-ChangeLog for XBoard/WinBoard\r
-\r
-* 04/15/2009: Updated the winboard.rtf of 4.3.15 with the 4.3.16\r
-additions, and a more fitting description of ICS-analysis mode.\r
-\r
-* 04/15/2009: Added internationalization to xengineoutput.c and\r
-xoptions.c. Fixed missing */ in xboard.c.\r
-\r
-* 04/13/2009: transferred all changes since 4.2.7 to 4.3.pre16, to make \r
-4.4.pre1, which should lead to a full merger of the 4.2 and 4.3 line\r
-\r
-* 02/28/2009: fixed an error in the parser. This should fix bug #22812. \r
- \r
-* 06/12/2005: bugfix some more possible buffer overflows. \r
- \r
-* 06/27/2004: added simple icsEngineAnalyze for xboard\r
-\r
-* 06/26/2004: added icsEngineAnalyze for winboard: Analyze observe games \r
-with a chessprogram on a Internet Chess Server (ICS) \r
-\r
-* 02/12/2004: Bugfix ICS interaction console crashed while chess \r
-engine starting and user type in some stuff. We wait now to finish \r
-the engine boot.\r
-\r
-* 02/11/2004: Winboard: Added color lines for the ics interaction \r
-console if zippy used \r
- \r
-* 02/09/2004: Added mousewheel support for winboard. Play moves \r
-backward and forward with the mousewheel. \r
- \r
-xboard/WinBoard 4.2.7 -- Fri Nov 28 13:36:00 PST 2003 -- Tim Mann\r
-\r
-* 11/26/2003: In WinBoard, setting the -debug flag now logs ICS output\r
-to WinBoard.debug too. (This isn't needed in xboard because ICS\r
-output already goes to stdout, so it's easy to capture along with the\r
-debug output on stderr.) This was issue #280 in the ToDo file.\r
-\r
-* 11/23/2003: Cleaned up some minor problems in cygwin.mak. Thanks to\r
-Hans Werner Strube for the problem report.\r
-\r
-* 11/23/2003: Updated the default list of chess servers in\r
-winboard/defaults.h. Deleted two that appear to be dead and added a\r
-new one that is active.\r
-\r
-* 11/19/2003: Swapped icon_white.bm and icon_black.bm in XBoard.\r
-Hopefully this will get them the right way around by default on more X\r
-window managers. I wish I understood this better.\r
-\r
-* 11/18/2003: Implemented a simple 32-bit random number generator for\r
-WinBoard, replacing the Windows rand(), which ranges only up to\r
-0x7fff. Formerly on Windows, only zippy.lines sayings that started in\r
-the first 32767 bytes of the file could ever be used. This was issue\r
-#505 from the ToDo file.\r
-\r
-* 11/16/2003: The xboard man page and info files are now built from a\r
-common set of texinfo source files, and the xboard man page now covers\r
-cmail as well. Formerly, ever since the texinfo file was first\r
-contributed to the project, it was separate from the man page and the\r
-two files had to be updated in parallel, making for a maintenance\r
-nightmare. To make combining the files possible, I took the Perl\r
-script "texi2man" from the GNU Units project and added support for a\r
-larger subset of the texinfo markup language. I then carefully\r
-compared the old man page and old texinfo file to make sure the latest\r
-and clearest words survived into the new combined texinfo file. It\r
-would be great to merge in WinBoard's help file too, but that's a\r
-larger project. It would have to be heavily conditionalized to\r
-deal with differences in features between XBoard and WinBoard.\r
-\r
-* 11/15/2003: Cleaned up and applied a small patch from Daniel\r
-Mehrmann, to stop overly long PVs in thinking output from causing a\r
-buffer overflow crash in backend.c.\r
- \r
-* 11/5/2003: When a chess engine sends a "telluser" command (including\r
-the cases where "tellall" or "tellopponent" acts like telluser), the\r
-information now goes into a nonmodel popup that is automatically\r
-dismissed when the user clicks anywhere on the board. This fix is\r
-more significant on WinBoard, where formerly you got a fully modal\r
-dialog that had to be dismissed by clicking on OK before anything else\r
-could happen. The bug was issue #406 in the ToDo file.\r
-\r
-* 11/1/2003: Removed email addresses from this file to reduce spam\r
-load, as it gets linked to from the Web.\r
-\r
-* 11/1/2003: Updated READ_ME and winboard/READ_ME.txt.\r
-\r
-* Modified xboard and winboard makefiles to be able to build the\r
-project in the new combined directory structure.\r
-\r
-* Applied a small security fix to pxboard, from Martin Maeok.\r
-\r
-* Fixed a bug in the game list dialog. The change in 4.2.6 to opening\r
-games in text mode (meant to avoid getting extra \r's into comments)\r
-caused a new bug in determining seek offsets when parsing a game file\r
-to form the game list. Also, the change was incomplete; on some code\r
-paths games were still being opened in binary mode. Thanks to Lenik\r
-Terenin for reporting the offset bug. I've now gone back to always\r
-using binary mode when reading game files, and I've fixed the comment\r
-bug by adding code to remove \r's from parsed comments explicitly. I\r
-still use text mode for writing game files so that games written by\r
-WinBoard will have Windows-style line endings.\r
-\r
-* Fix for minor bug in WinBoard installer. If you chose a non-default\r
-destination directory, the default directory was still used for a\r
-couple of unimportant things, namely setting the App Paths registry\r
-keys (unused by WinBoard) and trying to copy the existing WinBoard.ini\r
-file to WinBoard.old. I inherited this bug from the InstallShield 5\r
-sample template. Thanks to "l.d." for noticing the incorrect keys.\r
-\r
-* Patch from Chris Priest: when two engines are being run through rsh,\r
-avoid reusing the same stderr port for both. I'm not sure why this\r
-should be needed, but it's harmless, at least.\r
-\r
-* Bugfix: The kludge to deal with old engines that give an error\r
-message because they don't know the "st" command was too sloppy; it\r
-could hit on an "st" substring anywhere in an error message. GNU\r
-Chess 4 is the only engine I know of where the kludge was needed, so I\r
-changed the kludge to match a longer, more GNU-specific string.\r
-\r
-* Changed the WinBoard self-extracting installer to choose a unique\r
-temporary subdirectory name within the Windows temp directory instead\r
-of always putting wb-setup directly in temp. Besides being better\r
-practice, this avoids the need to deltree wb-setup first, which\r
-occasionally alarms someone who thinks that deltree is only used by\r
-trojans to delete all your files. (Yes, I'm serious.)\r
-\r
-* Fixed a bug where FICS-style "wild/0" strings were not parsed as the\r
-proper wild type. The "/" was not being skipped.\r
-\r
-* Fixed a WinBoard bug where temporary files created by game\r
-copy/paste were being created in the root directory of the current\r
-drive instead of the TMP directory and were not always deleted on exit.\r
-\r
-* Fixed a small bug in winboard.c's ErrorDialog() function. Thanks to\r
-"Ron" (no last name given). The bug might have caused a problem when\r
-pressing OK or Cancel in an error dialog when more than one error\r
-dialog was being displayed, but I'm not really sure.\r
-\r
-* Removed a hack that worked around a bug in very old versions of\r
-Crafty, where it would sometimes reply "illegal move" to a "."\r
-command. The hack kept us from recognizing real illegal move messages\r
-in analyze mode from engines that don't respond to the "." command.\r
-Thanks to Fabien Letouzey for the report.\r
-\r
-* Fixed a bug in the xboard version of GetDelayedEvent. It would\r
-return the most recently scheduled event even if it had already fired.\r
-This caused at least one visible error: in -ics -xreuse mode, starting\r
-the engine again and seeing another "feature done=1" would re-run the\r
-initialization code in InitBackEnd3, including the code that opens the\r
-connection to ICS. The WinBoard version didn't have this bug. Thanks\r
-to Bob Hyatt for the bug report.\r
-\r
-* The promotion popup for ICC wild 26 (giveaway) now includes King.\r
-Thanks to Fredrik Josefsson for the bug report.\r
-\r
-* The first game in a file (or being pasted from the clipboard) can\r
-now start with a bare move -- no PGN tags, no move number "1", etc.\r
-Suggested by Shane Harrelson. One could imagine taking this farther\r
-and accepting something like "e4 e5 1/2-1/2 d4 d5" as two games, but\r
-I haven't done that.\r
-\r
-* Bug fix: xboard didn't really accept a paste of multiple games,\r
-contrary to what I wrote when adding the feature to WinBoard in\r
-4.2.4. Now it works in both.\r
-\r
-* Fixed generic start/end of game messages to work on chess.net, where\r
-they put ratings in parens after the player names.\r
-\r
-* Updated config.sub and config.guess to newer versions from\r
-automake-1.4p5-2. This makes configure work with MacOS X + X11.\r
-\r
-* Bugfix: when examining a game fragment on FICS where black plays\r
-first, don't show two "(0:00.000)" times on the initial "none" move.\r
-\r
-* If TestLegality is on and one of the engines makes an illegal move\r
-in TwoMachines mode, it forfeits immediately. Formerly the game would\r
-get stuck at that point and the engine that made the illegal move\r
-would eventually lose on time.\r
-\r
-xboard/WinBoard 4.2.6 -- Fri Feb 1 22:26:31 PST 2002\r
-Tim Mann\r
-\r
-Another small bugfix release.\r
-\r
-* Put in a small change from Alexander Mai to allow xboard to build in\r
-an OS/2 EMX environment.\r
-\r
-* Fix WinBoard-only bug where editing a PGN file with comments would\r
-insert more \r characters before the \n after every Load/Save cycle.\r
-For some unknown reason we were reading the files in "rb" mode but\r
-writing them in "a" mode, so we kept the \r characters on reading and\r
-added an extra one on writing. Fix: change the "rb" to "r". Thanks\r
-to Joel (last name not given) for the bug report.\r
-\r
-* Put the arguments to rsh/remsh in the right order for better\r
-portability. Thanks to Michael Kalisz.\r
-\r
-* FreezeUI is now implemented in WinBoard; it was previously only\r
-implemented in xboard. This function prevents the user from entering\r
-moves or other commands while we are waiting for an engine to\r
-initialize itself. Implementing it fixes a bug where the user could\r
-start a game (etc.) during feature negotiation. One of the symptoms\r
-of this bug was that we could send "new" one or move moves *after* the\r
-first game started!\r
-\r
-* Fixed some handle leaks (WinBoard only), including a nasty one that\r
-leaked one handle per command sent to ICS. Thanks to several folks\r
-who helped characterize the bug and tried to look for leaks.\r
-\r
-* We now install and look for the info file in ${prefix}/share/info\r
-instead of ${prefix}/info. The latter is still the default in\r
-autoconf, but the former is currently used in Red Hat Linux and\r
-probably elsewhere.\r
-\r
-xboard/WinBoard 4.2.5 -- Sat Dec 15 11:42:51 PST 2001\r
-Tim Mann\r
-\r
-* Changed the bundled GNU Chess 5.02 in the WinBoard package to\r
-include a much smaller book and to use much less hash table space by\r
-default (8 MB transposition table, 0.5 MB pawn evaluation table). The\r
-large book included with 4.2.4 made the WinBoard download too big for\r
-some people, and the default hash tables were larger than the\r
-available physical memory on some people's computers. I built the\r
-small book by running Crafty's "small.zip" book line collection\r
-through a Perl script that makes it look enough like real PGN games\r
-that the GNU Chess book builder will accept it. The script and some\r
-minor patches to GNU Chess 5 are available in the WinBoard source\r
-distribution and at http://www.tim-mann.org/gnuchess.html.\r
-\r
-* Fixed a bug in the code that deals with engines that complain that\r
-"time" and "otim" are illegal moves. This was a new bug in 4.2.4.\r
-\r
-* Revamped the implementation of ToStart in analysis mode. Formerly\r
-there was some ill-conceived code that would try to get back to the\r
-start of the game by doing a "new" command (and all the followup\r
-commands that requires) while remaining in analysis mode. This is\r
-problematic for engine authors to support, though it works with\r
-Crafty. This code was trying to solve the problem of ToStart being\r
-slow because the engine would try to start an analysis after every\r
-"undo" command all the way back to the start. But ToEnd already had a\r
-much better solution to this problem, and now ToStart does the same\r
-thing: we exit from analysis mode and enter force mode instead,\r
-make/unmake moves to get to the end/start of the game, and then\r
-reenter analysis mode.\r
-\r
-* Formerly, Zippy could try to start playing a game before the engine\r
-was initialized; that is, during the initial timeout for protover 1\r
-engines, or before "feature done=1" for protover 2 engines. We now\r
-wait until the engine is initialized before connecting to ICS, which\r
-fixes this in the common case. If you turn off engine reuse for\r
-multiple games (that is, if you give the -xreuse option), there could\r
-still be problems; see item 503 in the ToDo file. Thanks to Dieter\r
-Buerssner for the bug report.\r
-\r
-* Bugfix: All WinBoard versions since the merge with WinBoard Plus\r
-(but not xboard) have had a bug in changing the PeriodicUpdates,\r
-PonderNextMove, and ShowThinking options from the menu. The bug\r
-mostly just caused changing these options during a game to not take\r
-effect until after the next reset. For TwoMachines games, though,\r
-changing PonderNextMove just before the game would take effect\r
-immediately for the second engine but not until the next game for the\r
-first engine. Thanks to Koundinya Veluri for the bug report.\r
-\r
-* Bugfix: In 4.2.4, we sometimes got confused when trying to leave and\r
-reenter analyze mode. One symptom was that Analyze File did not work.\r
-Thanks to Igor Syry for the bug report.\r
-\r
-xboard/WinBoard 4.2.4 -- Sun Dec 9 14:56:30 PST 2001\r
-Tim Mann\r
- \r
-* WinBoard now includes GNU Chess 5.02 in place of GNU Chess 5.00.\r
-\r
-* WinBoard's PasteGameFromClipboard will now handle a paste with\r
-multiple games in it, popping up the game list dialog. xboard\r
-already did this. Suggested by Robert Gerstman.\r
-\r
-* We now use the "clearboard" command on ICC where appropriate.\r
-\r
-* Bugfix: don't generate a bogus "variant normal" command to an engine\r
-for the loadable ICC wild types that we internally flag as\r
-VariantLoadable. Also clarified the message that Zippy sends when\r
-declining such wild games -- it can't deal with the possibility of\r
-loading an arbitrary position into the game. Thanks to Dieter\r
-Buerssner for reporting the problem. It would be nice to be able to\r
-actually play these wild types some day; presumably there would have\r
-to be an option to either send "loadgame" with a specified position,\r
-or to deal with an opponent sending it.\r
-\r
-* If we get a holdings message from ICS when we thought we were\r
-playing normal chess, we now try asking for a move list so that we can\r
-find out from the header what's really happening. Formerly we guessed\r
-bughouse in this case. Response to a comment from Gian-Carlo\r
-Pascutto.\r
-\r
-* Fixed two longstanding bugs in the clock code. These affected only\r
-play between a user and a local engine, or between two local engines,\r
-not ICS play. (1) The last fractional second used by a player before\r
-moving and virtually pushing his clock was being charged to his\r
-opponent instead of to him. (2) The time and otim commands were being\r
-sent to an engine before the (buggy) fractional second update was\r
-done. The second bug was pretty harmless in itself, but the first one\r
-was serious. Many thanks to Peter Rosendahl for carefully diagnosing\r
-and reporting these bugs!\r
-\r
-* Changed WinBoard timestamp key. Nothing is changed other than the\r
-key and a recompilation. ICC may phase out the old key soon; if they\r
-do, you'll need to use the timestamp.exe from WinBoard 4.2.4 or later\r
-to connect to chessclub.com.\r
-\r
-* Fixed an xboard-only bug where most dialogs would not take keyboard\r
-input unless the mouse was actually over the dialog, even if the\r
-dialog window had focus. Thanks to Jason Varsoke for the bug report.\r
-\r
-* Bugfix; Remember to send time and otim commands to engine before\r
-sending playother. Thanks to Bob Hyatt for the bug report. Also\r
-fixed a bug where time and otim were sometimes sent even with feature\r
-time=0.\r
-\r
-* Added small patches from Wilkin Ng that are meant to fix a crash in\r
-CopyGameToClipboard and a "can't unlock clipboard memory" error in\r
-PasteTextFromClipboard, under Windows 2000.\r
-\r
-* Changed cygwin.mak to not use -mno-cygwin. In other words, it now\r
-uses cygwin1.dll instead of the mingw libraries. This works around\r
-bugs in fileno() and stat() that I encountered in mingw. (fileno\r
-seems to always return 0. stat fails because the library routine uses\r
-a different definition of struct stat than the header files provide.)\r
-Thanks to Robert Gerstman for reporting the symptoms these bugs caused\r
-when WinBoard was compiled with Cygwin.\r
-\r
-* Added -showButtonBar option. This lets you delete the << < P > >>\r
-buttons and thus widen the message widget a bit.\r
-\r
-* Added code to address a very obscure bug. If an engine dies and\r
-needs to be restarted while in one of the analyze modes, it was not\r
-getting put back into analyze mode. This bug should not really ever\r
-have gotten tickled unless reuse was turned off and the engine sends\r
-game end commands (such as 1-0) when a game ends by rule while in\r
-analyze mode. The next version of the protocol spec will say that\r
-engines should not do that, but version 2 and earlier didn't address\r
-the issue.\r
-\r
-* We now use the FICS "iset ms 1" feature to get times in ms instead\r
-of seconds. Thanks to DAV for email telling me about this feature.\r
-\r
-* Changed clock display to show tenths of seconds for 9.9 seconds and\r
-less, instead of 0.9 seconds and less as before.\r
-\r
-* It has been discovered that Zippy can play simuls on ICC (but not on\r
-FICS). If you arrange for Zippy to send the ICC command "simulize" in\r
-the -zippyGameStart string, it will accept additional games while\r
-playing. Zippy will use the same engine for every game, so whenever\r
-it switches opponents, the engine's state will be reset with the "new"\r
-command. This will of course weaken its play, so don't enable simuls\r
-if you want your engine to have the highest possible rating. Zippy\r
-was never designed to work with simuls; it just works by accident, and\r
-it hasn't been tested much. So please report any bugs you notice, but\r
-don't expect them to be fixed rapidly. Thanks to Paul McGuire for\r
-noticing that this works.\r
- \r
-* Bugfix: Suppress the direct command to engine popup if there is no\r
-engine. In WinBoard this case used to cause a crash. Thanks to\r
-"Dargon" for the bug report.\r
-\r
-* Bugfix: formerly we did part of the engine initialization for the\r
-very first game too soon, before feature negotiation. One result of\r
-this is that engines would never get the "ics" command for the first\r
-game.\r
-\r
-* Lengthened timeout to detect protocol version 1 chess engines to 10\r
-seconds. This should reduce problems with protocol version 2 engines\r
-that are slow to initialize missing the timeout and not getting a\r
-chance to send their feature commands before the first game starts.\r
-\r
-* Klaus Friedel says that adding a short sleep to WinBoard after\r
-starting a new chess engine solves a problem that occurs under Windows\r
-2000, in which engines sometimes don't see the initial command(s) from\r
-WinBoard and hang. I don't understand how that can happen, but the\r
-sleep is harmless, so I've put it in. Others have also reported what\r
-may be the same problem, so hopefully this will fix it for them too.\r
-\r
-* Bugfix: editing the Result field in EditTags will no longer cause a\r
-later crash. Thanks to DAV for a clear bug report that let me\r
-reproduce the problem.\r
-\r
-* ICC wild 28 is now recognized as shatranj, but it is not supported.\r
-You might be able to play it by turning off Test Legality.\r
-\r
-* Formerly we would always turn off "feature time" if the engine\r
-printed an error message with the string "time" or "otim" in it; now\r
-we do that only if the message comes before the engine makes its first\r
-move. This change is useful because some engines spew a lot of bogus\r
-error messages about commands they don't fully parse, so something\r
-like "result 0-1 {White lost on time}" could generate such a message.\r
-Engines shouldn't do that, but if they do, mysteriously turning off\r
-"feature time" is not a good way to react.\r
-\r
-* Fixed an infrequently occurring Zippy bug: formerly, resuming from\r
-adjournment by position (that is, with GetMoveList turned off) or\r
-starting/resuming a wild game (nonstandard starting position) would\r
-try to set up the position without putting the engine into force mode\r
-first. That was probably tolerated by most engines, but if the\r
-position was black-to-play and the engine hadn't set feature\r
-setboard=1, then the fake "a2a3" move (which we use as a kludge to get\r
-black to be on move before sending the edit command) would appear to\r
-be a real move, and the engine might reply to it! This bug could also\r
-be seen when trying to use Zippy to play a simul -- something that\r
-Zippy was never designed to support, but which seems to mostly work\r
-anyway. Thanks to Paul McGuire for sending a WinBoard.debug file that\r
-showed the bug occurring. Some other cases of resuming adjournments\r
-or starting games from nonstandard positions may have been broken too;\r
-I think I've straightened out the problems.\r
-\r
-* Agreeing to a draw in the human vs. local engine case formerly did\r
-not work if the human offered first; now it does. A human's\r
-unsolicited offer is considered valid until he makes another move.\r
-Thanks to Bruce Moreland for the bug report.\r
-\r
-* Bugfix: We used to look for just "fr" in Event tags or strings from\r
-ICSes to recognize Fischer Random games. This caused a lot of false\r
-matches. Now we look for "wild/fr" instead, which is what FICS uses.\r
-\r
-* Bugfix: Clicking on a move in the MoveList window only updated the\r
-displayed position; if a chess engine was active, its state was not\r
-updated. Thanks to Alejandro Dubrovsky for the bug report.\r
- \r
-* Bugfix: The "resign" command from engine to xboard formerly did not\r
-work in ICS (Zippy) mode.\r
-\r
-* Bugfix: Formerly we would register a garbage premove if the user\r
-clicked on a piece, then clicked on an edge or outside the board. Now\r
-such an errant click is ignored.\r
-\r
-* Bugfix: GameEnds would send "exit" to an engine in analyze mode even\r
-if we did not actually want to leave analyze mode.\r
-\r
-* Bugfix: "feature pause" was being rejected. We don't currently use\r
-it, but that is no reason to reject it. Thanks to Gian-Carlo Pascutto\r
-for the bug report.\r
-\r
-* Bugfix: when "partner" needed to be sent both to ICS and the engine,\r
-Zippy was erroneously sending the ICS prefix character to the engine\r
-too. Thanks to Gian-Carlo Pascutto for the bug report.\r
-\r
-* Zippy now declines challenges when the engine is not yet ready to\r
-play again, instead of ignoring them. This is needed so that the\r
-server will let the opponent repeat the challenge. It might be better\r
-to remember such challenges and accept them when the engine is ready,\r
-but that would be a bit more complicated to implement.\r
-\r
-* Bugfix: Zippy's emotes didn't work on FICS because there, "i" is a\r
-built-in alias for "it", not a real command. So sending "$i foo" gave\r
-an error message instead of doing "it foo". We now leave out the\r
-alias-suppressing prefix for emotes.\r
-\r
-xboard/WinBoard 4.2.3 -- Mon Feb 19 19:55:05 PST 2001\r
-Tim Mann\r
-\r
-* Bugfix: The error message "Variant X not supported by gnuchessx"\r
-formerly could pop up even in -ncp mode.\r
-\r
-* Fixed an xboard bug in premove highlighting. If you had\r
-HighlightLastMove turned on, premoves got highlighted in\r
-highlightSquareColor (yellow) instead of premoveHighlightColor (red).\r
-\r
-* Modified premove again. Now we are back to displaying the move\r
-locally immediately after sending it to the server, as in versions\r
-prior to 4.2.1. This is good because it lets you register your next\r
-premove sooner. As a better fix to the problem that the change in\r
-4.2.1 had been trying to address, we now suppress animating the\r
-opponent's move if you have a premove reply pending. However, it's\r
-probably still a good idea for you to turn off AnimateMoves entirely\r
-if you are trying to play extremely fast games.\r
- \r
-* Removed an erroneous patch that left zombie chess engines around\r
-when both sigterm and reuse were turned off. (Bug was in xboard only,\r
-not winboard.)\r
-\r
-* Bugfix: loading a game with autostepping did not work for games with\r
-PGN result "*" (unfinished). This bug was introduced in 4.1.0, caused\r
-by some outdated code that was supposed to leave you in EditGame mode\r
-after loading an unfinished game. I fixed this, and also changed it\r
-to leave you in EditGame mode after loading *any* game, but without\r
-changing the tags to say it's an edited game. It's not really clear\r
-whether that is the best thing is to do here -- ideally, perhaps, the\r
-tags should change to say "edited game" if you actually make any\r
-changes, but that is harder to make work.\r
-\r
-xboard/WinBoard 4.2.2 -- Tue Feb 6 20:00:00 PST 2001\r
-Tim Mann\r
-\r
-* Fixed a problem introduced in 4.2.1. In -zippyPlay mode, 4.2.1\r
-started sending the initString immediately after the old game ended,\r
-but then when the next game started, it would still send "force" and\r
-another initString. Another problem was that the first initString put\r
-the engine out of sync with the displayed board position, though that\r
-might not usually have been noticeable. This is now changed to do a\r
-full Reset at the end of the previous game, and avoid doing a Reset at\r
-the start of a new game if we are still in BeginningOfGame mode.\r
-\r
-* Fixed some limitations in -zippyPlay mode. The engine was not being\r
-fed the moves or history of games that were displayed but not being\r
-played, so it would get confused if you tried to do something like\r
-examine a game, then enter EditGame mode from somewhere in the middle\r
-of the game.\r
-\r
-* Made a small change so that cygwin can compile xboard for Windows\r
-(an X server is required to run it). Thanks to Volker Zell. Most\r
-people would probably prefer to run WinBoard on Windows, however; note\r
-that cygwin could already compile WinBoard.\r
-\r
-* Added some missing documentation to engine-intf.html: It is okay to\r
-send "feature done=0" even before you receive the xboard and protover\r
-commands, if this is needed to give your engine enough time to\r
-initialize. See engine-intf.html for more discussion.\r
-\r
-* Bugfix: "feature done=0" did not work for the second engine; now it does.\r
-\r
-xboard/WinBoard 4.2.1 -- Sat Feb 3 19:52:26 PST 2001\r
-Tim Mann\r
-\r
-* Bugfix: in Zippy mode with feature san=1, the elapsed time was being\r
-sent to the engine after the SAN move; for example, "e4 (0:01)" was\r
-sent instead of just "e4".\r
-\r
-* It seems that scroll wheel mice with incompletely installed software\r
-(under Windows 95, at least) can send repeated middle button up events\r
-when the wheel is turned. Moved QuickPaste from middle button up to\r
-middle button down to avoid problems with this.\r
-\r
-* A premove is now sent *before* the opponent's move that it replies\r
-to is animated. The premove itself is no longer displayed (or\r
-animated) when sent; instead, it is displayed when the chess server\r
-echoes it back as a board update.\r
-\r
-* Bug fix: in -xreuse mode, xboard was only sending command line\r
-arguments to the engine the first time it was started. (WinBoard\r
-didn't have this bug.)\r
-\r
-* In -zippyPlay mode, we now initialize the chess engine for a new\r
-game immediately after the old game ends. (In -xreuse mode, this\r
-means starting a new engine process; in the default -reuse mode, it\r
-just means sending "new".) If the engine supports ping, we don't\r
-accept challenges until the "new" has finished. This should help\r
-avoid losing time (re)initializing the engine after the game starts.\r
-\r
-* We now handle the new FICS field in style 12 that says whether the\r
-clocks are ticking.\r
-\r
-* whiteFlag and blackFlag are now reset whenever an ICS board image\r
-arrives, giving autoflag a fresh chance to work.\r
-\r
-* Suppressed "geometry error" debug messages unless -debug flag is given.\r
-\r
-* Bugfix: avoid core dump on Solaris with -debug flag, caused by\r
-passing NULL to a %s format in GameEnds.\r
-\r
-* Added -firstProtocolVersion and -secondProtocolVersion. This will\r
-allow use of extremely broken engines that hang or die when given the\r
-"protover 2" command. It should be rarely if ever needed.\r
-\r
-* Zippy now strips highlights from player names in the Creating\r
-message; previously the ratings would not be extracted from this\r
-message properly if you had set the highlight variable.\r
-\r
-* Bug fix: Zippy with -zp but not -zt used to be fooled by false\r
-partner tells inside channel tells; e.g.: \r
-Garf(24): Garf (your partner) tells you: sit\r
-\r
-* Bug fix: when an engine reported its name with the new "feature\r
-myname=" command, we had been putting just that name into the window\r
-title even when in TwoMachines mode.\r
-\r
-* By default, WinBoard no longer uses the new feature introduced in\r
-4.2.0beta of keeping the ICS menu, ICS server list, and lists of chess\r
-engine command lines in separate files; instead, the lists are back in\r
-the winboard.ini file. This gets rid of some problems where the\r
-separate files could not be opened because the working directory was\r
-not set to WinBoard's installation directory.\r
-\r
-* WinBoard command lines and ini files now have another optional\r
-syntax for quoting an option value. All characters within { } curly\r
-braces are interpreted literally except for '}' itself. SaveSettings\r
-now uses this syntax for string values that contain a backslash or\r
-newline and do not contain a '}'. This should address the problem\r
-that the separate .ini files had been meant to fix; engine command\r
-line lists can now be written without \-escapes.\r
- \r
-* Fixed three bugs in relaying moves between engines in TwoMachines\r
-mode: an engine would be sent SAN if the *other* engine had set\r
-feature san=1, a relayed SAN move did not end with a newline, and\r
-feature usermove was not implemented for relayed moves.\r
-\r
-* Fixed several bugs in exiting: File/Exit would sometimes hang;\r
-timestamp/timeseal would not get killed off; an engine crash would\r
-cause error messages to be printed recursively until stack overflow.\r
-\r
-* Fixed a bug in the code to detect which ICS is in use and adapt to\r
-it; the chess.net case was broken.\r
-\r
-* Removed the leading alias-suppression character when sending a move\r
-to ICS, because it seemed to break accuclock on chess.net.\r
-\r
-* Fixed a bug where a FICS prompt like "10:01_fics%" would be matched\r
-as finger note number 10, causing a problem detecting when the user is\r
-logged in.\r
-\r
-* Added tellicsnoalias command to protocol.\r
-\r
-* Changed st command in protocol back to old behavior.\r
-\r
-* Added done=0 feature to protocol, to lengthen initial timeout.\r
-\r
-* Added missing -colorSeek command line option to xboard. (Was\r
-present in WinBoard.)\r
-\r
-* Bug fix: setting feature reuse=0 was not working.\r
-\r
-xboard/WinBoard 4.2.0beta -- Sat Dec 16 16:34:56 PST 2000\r
-Tim Mann\r
-\r
-* Setting -searchTime no longer turns off -clockMode. Note that when\r
--searchTime is set, some engines may search for the lesser of\r
-searchTime and the amount of time their normal clock management would\r
-dictate, while others will disable their normal clock management and\r
-always search for exactly searchTime.\r
-\r
-* Fixed WinBoard bug where on Windows 2000 (and maybe Windows 98) the\r
-ICS Interaction window would scroll back to the top whenever it filled\r
-to capacity and WinBoard trimmed some text off the top.\r
-\r
-* Changed xboard dragging so that the center of the dragged piece is\r
-forced to be over the mouse cursor. (WinBoard dragging already worked\r
-that way.) This should avoid confusing cases when you start a drag\r
-with the mouse near the edge of a square -- formerly most or all of\r
-the piece could be over one square but the mouse cursor over another.\r
-Suggested by DAV.\r
-\r
-* Added move list window for xboard. Code contributed by Manuel\r
-Hoelss and re-hacked a bit by me. Performance of this window is poor,\r
-because the implementation regenerates the entire window contents\r
-whenever anything changes. It's hard to avoid this when using the\r
-Athena List widget, though we could be a little smarter and notice\r
-when the current move number has changed but the move list has not.\r
-There are also several drawing problems caused by bugs in the Athena\r
-Form and List widgets. The window should not really allow a\r
-horizontal scroll bar, but the bugs are much worse if I turn it off.\r
-In both Xaw and Xaw3d, the List widget tries to resize itself when\r
-XawListChange is called, even if you tell it not to; and what's worse,\r
-if the widget cannot resize itself to be large enough to avoid\r
-clipping any of the list item, it does not change the list! Arrgh.\r
-On top of that, the Xaw Form widget is very buggy in XFree86 4.0.1\r
-(X11R6.4.3).\r
-\r
-* The OK button in the WinBoard startup dialog is now simply disabled\r
-if none of the radio buttons is selected, instead of bringing up an\r
-error dialog. Suggested by Ted Milbaugh.\r
- \r
-* Used ping to address the worst of the race conditions in the\r
-protocol. Now if an engine supports ping, we ping it after sending\r
-the "new" command and after trying to place it in force mode at the\r
-end of a game. When a ping has been sent and the corresponding pong\r
-has not yet come back, we (1) ignore or undo any moves the engine\r
-sends, (2) ignore game end messages (such as "offer draw", etc.) from\r
-the engine, (3) ignore thinking output from the engine, (4) delay\r
-starting the next game if in -matchGames mode, (5) in -zippyPlay mode,\r
-respond to challenges with a polite message to try again soon instead\r
-of accepting them. There are a few more things that should be done\r
-(and item 5 might not be quite what we want), but it's hard to fit\r
-them all into the existing code.\r
- \r
-* Patched the version of GNU Chess 5.00 included with WinBoard to\r
-support protover, feature, setboard, and ping, and to fix some minor\r
-bugs. See gnu500+.patch.\r
-\r
-* Changed the GNU Chess 4 kludges for missing "st" and "sd" commands\r
-to be invoked only if the engine gives an error message for "st" or\r
-"sd", and to always use protocol commands instead of engine\r
-command-line options. See "Idioms" in engine-intf.html.\r
-\r
-* Added new protocol command "protover 2" to tell the engine what\r
-version of the protocol is in use. Version 2 is still compatible with\r
-old engines; see engine-intf.html.\r
-\r
-* Add new protocol command "feature ..." The engine can send this in\r
-response to the protover command command, to say what extended\r
-protocol features it would like to enable, etc. xboard responds\r
-"accepted F" or "rejected F" for each feature F that is set. See\r
-engine-intf.html.\r
-\r
-* Added new protocol command "setboard <fen>". This is an alternative\r
-to "edit", used only if the engine says "feature setboard=1".\r
-\r
-* Added new protocol command "ping <msg>". The engine is supposed to\r
-respond "pong <msg>". This gives us a tool to fix some race\r
-conditions in the protocol, but it is not used to the fullest yet.\r
-\r
-* Added new protocol command "tellopponent". This will do a "say" if\r
-you're on a chess server in Zippy mode, or pop up an information\r
-dialog otherwise.\r
-\r
-* Added new protocol command "tellall". This will do a "kibitz" if\r
-you're on a chess server in Zippy mode, or pop up an information\r
-dialog otherwise.\r
-\r
-* Added new protocol command "tellothers". This will do a "whisper" if\r
-you're on a chess server in Zippy mode, or do nothing otherwise.\r
-\r
-* Changed the WinBoard /icsNames, /icsMenu, /firstChessProgramNames,\r
-and /secondChessProgramNames options to accept a filename preceded by\r
-"@", meaning to find the value in the file. Changed the defaults to\r
-use this feature, with filenames icsnames.ini, icsmenu.ini, fcp.ini,\r
-and scp.ini. This should make it easier for users to edit the values,\r
-since one less level of quoting is needed, and each value is in its\r
-own file, not mixed into winboard.ini. Those who upgrade from an\r
-older winboard version and already have a winboard.ini file will not\r
-automatically have these values moved to a file; that has to be done\r
-by hand if desired.\r
-\r
-* We now strip .exe from engine names for "name" command, tags, etc.\r
-\r
-* Allowed WinBoard input widget to hold more than one line. You can get\r
-a newline into the widget with copy/paste or with Ctrl+Enter.\r
-\r
-* Fixed an xboard bug where the [P] button would appear in the\r
-opposite highlight state from what it should be after being pressed.\r
-\r
-* We now use the "/" or "$" alias suppression feature on the chess\r
-servers, to avoid problems if the user inadvertently aliases a\r
-needed command to something else.\r
-\r
-* Changed the method used to deiconize xboard in AutoRaise and cmail.\r
-This may fix bugs under some window managers where after\r
-deiconization, the board window was mapped but nothing was drawn\r
-inside.\r
-\r
-* Preliminary, partial support for playing several chess variants\r
-against a local engine or editing variant games. The -variant option\r
-must be given on the command line or WinBoard startup dialog; there is\r
-no menu. The current variant is not displayed (except in the\r
-Tags/EditTags window). Many variants will not work quite right even\r
-if the engine supports them; see item 326 in the ToDo file for\r
-details.\r
-\r
-* Added a workaround to detect the variant type when examining a\r
-scratch wild game on an ICS.\r
-\r
-* Fixed two cases where "variant" command should be sent to the engine\r
-when necessary but was not: loading a game from a file and restarting\r
-a dead engine. Thanks to Gian-Carlo Pascutto.\r
-\r
-* Added missing support for FICS games that start from a bsetup position\r
-with Black moving first.\r
-\r
-* Fixed a bug in loading a file from the game list window while in\r
-Analysis or AnalyzeFile mode. This now leaves us in AnalyzeFile\r
-mode, analyzing the new file.\r
-\r
-* Fixed a bug in loading games with a comment before the first move.\r
-\r
-* Fixed a bug in handling LoadGame (or -lgf) with -td 0.\r
-\r
-* Added a command line option to select an initial minor mode from the\r
-Mode menu. This should satisfy requests from a couple of users with\r
-special applications.\r
-\r
-* Fixed a problem where some things in WinBoard's General Options\r
-dialog box were grayed out at the wrong time.\r
-\r
-* We look for a few messages from the chess engine pipe that are\r
-intended to catch problems starting an engine via rsh, such as "No\r
-such file". Moved code so that these strings won't match until other\r
-protocol messages have been looked for, and documented the messages in\r
-engine-intf.html.\r
-\r
-* Fixed the WinBoard bug that sometimes made the console input box\r
-white-on-white even when not in password-entry mode.\r
-\r
-* Small changes to WinBoard to be compilable with the latest Cygwin\r
-net release (as of 10-16-2000). Thanks to Mark Schoenberg.\r
-\r
-* Recompiled GNU Chess 5.0 for WinBoard with the latest Cygwin net\r
-release (as of 10-16-2000). Also rebuilt the book just to be sure,\r
-since I had one bug report about it. It came out identical and seems\r
-to work fine.\r
-\r
-* Added messages for some common InstallShield errors instead of just\r
-printing InstallShield's stupid error code numbers.\r
-\r
-* Added -firstComputerString and -secondComputerString, allowing you\r
-to suppress or change the command that is sent to a chess engine when\r
-its opponent is another computer.\r
-\r
-* Added "configure --with-Xaw3d" to allow use of Xaw3d widgets instead\r
-of Xaw widgets in xboard. Thanks to Johnny C. Lam of the NetBSD\r
-project. I've left Xaw as the default because Xaw3d is too ugly.\r
- \r
-* The version of the Xaw Form widget released in XFree86 4.0.1\r
-(X11R6.4.3) has a bug that causes xboard to display the button bar\r
-on top of the message widget. I've reported the bug and have\r
-installed a kludge workaround into xboard.\r
-\r
-xboard/WinBoard 4.1.0 -- Sun Sep 17 17:30:14 PDT 2000\r
-Tim Mann\r
-\r
-* Merged Winboard Plus 4.0.8 from Mark Williams into xboard\r
- source pool. Status of Winboard Plus features in xboard:\r
-\r
- - White pieces now have borders, but the implementation is\r
- completely different from WinBoard's; see below.\r
-\r
- - Options menu not changed, probably won't be.\r
-\r
- - Copy&paste support working, using Mark's changes to backend.c, Ben\r
- Nye's changes to xboard.c for FEN positions, and some code of my\r
- own in xboard.c for PGN games.\r
-\r
- - Premove hooked up and working. No pre-first-move, though.\r
-\r
- - ICS Alarm hooked up and working.\r
-\r
- - Auto-flip working.\r
-\r
- - PGN Training mode hooked up and working.\r
-\r
- - Improved menu item enable/disable working.\r
-\r
- - Improved >> button working.\r
-\r
- - Auto activate board working. I changed this to be optional; you\r
- might not always want it, especially in Zippy mode.\r
-\r
- - Blindfold working.\r
-\r
- - Documentation updated.\r
-\r
-* Fixed more colorization bugs. Commands like "message foo tells you:\r
-xxx" and "tell 33 tells you: xxx" will no longer generate bogus\r
-colorization.\r
-\r
-* Added low-tech sound support to xboard, by invoking an external\r
-program on a filename for each sound to be played.\r
- \r
-* ICC wild 27 is now recognized as VariantAtomic, and it sets the\r
-"ignore check" flag, but is not otherwise supported.\r
-\r
-* Converted the piece bitmaps from .bm to .xpm for use with xboard's\r
-xpm support. (An .xim version was not created.) Wrote a shell script\r
-using ImageMagick to do the conversion and to bucket fill from\r
-coordinate 0,0 with the background color. Used xpaint by hand to\r
-clean up a few pieces where background color "leaked" into the inside\r
-or didn't flow all the way around the outside, then a sed script to\r
-fix up color names and bitmap names in the xpaint output. If any more\r
-sizes are added later, they should be straightforward to convert with\r
-reference to the existing scripts. With this conversion, not only do\r
-the white pieces now have dark borders, but (unlike with WinBoard) the\r
-light details on the black pieces are opaque.\r
-\r
-* If the XPM library is found when building xboard, the new xpm pieces\r
-are compiled in as the default. External bitmap (or xpm) pieces can\r
-still be used by giving the -bitmapDirectory (or -xpmDirectory)\r
-option. If the XPM library is not found, the old bitmap pieces are\r
-the default. In this case external bitmap (or xim) pieces can be used\r
-by giving the -bitmapDirectory (or -xpmDirectory) option. There is no\r
-way to compile in xim pieces.\r
-\r
-Winboard Plus 4.0.8 -- Sat Aug 5 15:51 PDT 2000 \r
-Mark Williams\r
-\r
-* Bugfix release.\r
-\r
-* Main menu now visible in Win NT. Thanks to Microsoft for creating a \r
-compiler which auto-mutilates the WinBoard.rc file so that the menu is\r
-displayed under Win 98 but not Win NT. I fixed the problem by hand editing the\r
-.rc file. Sigh.\r
-\r
-* "Reset game" now works properly when invoked from Analysis mode when two\r
-engines are present. Correction of bug introduced in Winboard Plus. Thanks to\r
-Mogens Larsen for reporting the bug.\r
-\r
-* Pasting a FEN position with Black to move now works in all modes.\r
-Thanks to Mogens Larsen for reporting the bug.\r
-\r
-* Added gnuchess.dat to the distribution and a couple of text files that were\r
-missing in 4.0.7.\r
-\r
-*** Merged in the following changes from Tim Mann:\r
-\r
-* Bugfix: Highlights would sometimes not be taken down, at least in\r
-xboard. The problem is that SetHighlight works in chess coordinates,\r
-not view coordinates, so if flipView has been toggled since the\r
-highlight was put up, it gets taken down from the wrong square. Fixed\r
-by being careful to call ClearHighlights before toggling flipView, not\r
-after. Ugh.\r
-\r
-* Bugfix: HighlightLastMove would sometimes highlight square a1 after\r
-a FICS "tomove black" command.\r
-\r
-* Bugfix: a move list with initial position that has black to play was\r
-not being handled correctly.\r
-\r
-* Removed "decline abort" and "decline adjourn" commands from Zippy.\r
-The syntax is changing on FICS, and Zippy really doesn't have to\r
-explicitly decline the requests anyway; it's sufficient to not accept\r
-them.\r
-\r
-* ICC wild 26 is now recognized as VariantSuicide (the FICS name; ICC\r
-calls it "giveaway").\r
-\r
-* Bugfix: PGN games with black to move in the initial position weren't\r
-being legality checked correctly. I think this was introduced in\r
-4.0.6 when I fixed a different PGN bug. Thanks to Mark Williams for\r
-spotting the bug and suggesting a fix.\r
- \r
-* Bugfix: the initial "name(" of a kibitz wasn't being colorized.\r
-\r
-Winboard Plus 4.0.7 -- Thu May 12 17:57 PDT 2000 \r
-Mark Williams\r
-\r
-* New white pieces with black borders.\r
-\r
-* Major overhaul to Options menu. New dialogs for setting General Options,\r
- Board Options, ICS Options, Sounds, Fonts, Colors.\r
-\r
-* Clipboard support for PGN game scores and FEN positions.\r
-\r
-* Optional ICS Premove with user-specified first moves for White and Black.\r
-\r
-* New sound events: ICS Win, ICS Loss, ICS Draw, ICS Unfinished, ICS Alarm.\r
-\r
-* New auto-flip option when playing against a chess program.\r
-\r
-* Added PGN Training mode.\r
-\r
-* Certain menu options now disabled while program is thinking.\r
-\r
-* ">>" button now always goes to the end of the game.\r
-\r
-* In ICS mode, the board is automatically activated at the start of a\r
-new game.\r
-\r
-4.0.7 -- Sun Mar 5 17:17:49 PST 2000 Tim Mann\r
-\r
-* Fixed a nasty bug in parsing ICS game histories that was introduced\r
-in 4.0.6.\r
- \r
-4.0.6 -- Fri Mar 3 16:20:11 PST 2000 Tim Mann\r
-\r
-* Fixed bugs in Zippy's code for responding to messages sent with the\r
-ICS "message" command.\r
- \r
-* Fixed bugs where xboard could still create dialogs partially off the\r
-top of the screen. Fixed unwanted interactions between initial sizes\r
-and positions of various unrelated xboard dialogs. Deleted\r
-borderXoffset and borderYoffset resources.\r
-\r
-* Fixed restoring the xterm name on exit to work in more cases.\r
- \r
-* Small fix to the WinBoard self-extracting installer: when it starts\r
-up, it now always deletes any old wb-setup directory left over from a\r
-previous installation. Formerly this worked only on Windows 95/98, so\r
-on NT the self-extractor would sometimes stop and ask the user whether\r
-it was OK to overwrite the old wb-setup files.\r
-\r
-* Modified WinBoard to be compilable with the free Cygwin tools\r
-available from http://sourceware.cygnus.com/cygwin/. Based on work by\r
-Mark Schoenberg. (His mods were enough to get WinBoard through the\r
-compiler, but a few things were broken along the way, so I reworked them.)\r
- \r
-* Merged changes from Don Fong to make WinBoard compilable with\r
-Borland C++ 4.5. I do not have Borland C++ and am unable to test with\r
-it, but I did make sure the changes don't stop it working with MSVC++\r
-5.0 and Cygwin.\r
-\r
-* Forbade entering TwoMachines mode from MachineWhite or MachineBlack\r
-mode when machine is on move. This used to confuse the engine and\r
-cause problems, because when we try to get the engine to stop, it\r
-might make a move first, and it might not do that immediately.\r
- \r
-* Variant classification now deals with new ICC wild 25, classifying\r
-it as "3check". Also, we are now conservative about new wild numbers\r
-we don't know about, classifying them as "unknown" instead of\r
-"normal".\r
-\r
-* Replaced bad GNU Chess 5.00 book in WinBoard distribution with a\r
-correct one. 1.e4 now no longer takes GNU Chess 5.00 out of book!\r
-Thanks to Pete Galati.\r
-\r
-* Made move parser accept and ignore nonstandard ep suffix on PGN moves,\r
-e.g., "exf6ep" or "exf6e.p."\r
-\r
-* Fixed bugs in parsing PGN files starting with no move number, or\r
-with a move number other than "1." (including "1..."). Thanks to\r
-Michael Soulier and Stefan Zipproth for example PGN files\r
-demonstrating the bugs.\r
- \r
-* Changed InitComboStringsFromString to not modify the input string;\r
-this caused an exception when WinBoard was compiled with MSVC++ 6.\r
-Thanks to Bert Tuyt for the report.\r
-\r
-* In WinBoard, dragging a piece off the edge of the board without\r
-releasing the mouse button no longer instantly aborts the move. You\r
-still must release the mouse button inside a square to complete a\r
-move, but you can now drag off the edge and come back inside.\r
- \r
-* WinBoard bugfix: If you went into EditGame or EditPosition mode\r
-while observing or playing an ICS game, and a new move came in\r
-(snapping you back to ICSClient mode) while you were dragging a piece\r
-around, the drag state would not be reset, causing the piece you were\r
-dragging to remain on the board wherever you dropped it. Thanks to\r
-David Brinegar for the bug report.\r
-\r
-* WinBoard bugfix: If you moved or resized the board while your\r
-opponent was moving, and you had AnimateMoving on, his move would not\r
-be displayed until after your next move. Thanks to DAV for reporting\r
-the bug repeatedly until I finally understood it.\r
-\r
-* Added a Zippy "farewell" feature; see zippy.README.\r
- \r
-* Fixed a bug (xboard only) in processing -zippyReplayTimeout on the\r
-command line. Thanks to Steve Beer for the report and patch.\r
-\r
-* Send "computer" command to both sides in TwoMachines matches.\r
- \r
-* Fixed a Y2K bug in Evan's cmail code! Thanks to Brian Mays for the\r
-report and patch.\r
- \r
-* Bugfix: Initialize variant field of GameInfo struct in gameinfo.c.\r
-This could cause crashes in LoadGame. Thanks to Andrzej Nagorko.\r
- \r
-* Fixed several pattern matching problems: Finger notes and formula\r
-vars no longer get replied to by zippyTalk or colorized. Channel\r
-tells by players with many titles are now colorized fully, and\r
-zippyTalk handles channel tells by such players correctly. The shout\r
-"--> foo(99): bar" no longer gets colorized as a channel tell. Code\r
-is cleaned up a bit, and autocomment capture now uses the same\r
-criteria as colorization.\r
-\r
-* xboard fix: Enter key now closes error popups as in WinBoard.\r
-Especially nice for the "Exiting: Connection closed by ICS" popup.\r
-\r
-4.0.5 -- Tue Dec 7 10:30:40 PST 1999 Tim Mann\r
-\r
-* Added missing documentation of SIGTERM usage into engine-intf.html.\r
-\r
-* Bugfix: New -zippyReplayTimeout option was misspelled in WinBoard as\r
--zippyReplyTimeout. Thanks to Francesco Di Tolla.\r
- \r
-* xboard -ics now restores the xterm's original title upon exit, at\r
-least if $WINDOWID is set.\r
-\r
-* Bugfix: -matchGames mode wasn't terminating properly. Final score\r
-popup would come up twice and engines would not be killed off. Thanks\r
-to Frank Quisinsky for the bug report. Bug was introduced in 4.0.4.\r
-\r
-* Bugfix: "tell 50 foo shouts: bar" no longer gets colored as a shout;\r
-similarly for "...s-shouts:" and "...c-shouts:". Thanks to David Lee\r
-for the bug report.\r
-\r
-4.0.4 -- Fri Dec 3 17:51:27 PST 1999 Tim Mann\r
-\r
-* Bug fix: formerly if you invoked SaveGame from EditPosition mode\r
-with black to play, the position was not saved properly. As a quick\r
-fix, SaveGame now takes you out of EditPosition mode before saving.\r
-\r
-* Changed -matchGames to keep track of the score (won-lost-drawn) and\r
-display it in the banner. The final score is displayed in a modal\r
-popup before the program exits.\r
-\r
-* Changed "Connection closed by ICS" to display in a model popup\r
-before the program exits.\r
-\r
-* Added -popupExitMessage option, default on. Setting this to false\r
-suppresses the modal popups that you sometimes get just before\r
-xboard/winboard exits -- both the two new ones listed above and the\r
-existing Fatal Error popup. This is useful when running Zippy\r
-unattended from a shell script (or .bat file) that loops and starts a\r
-new copy after a time delay when there is an error.\r
-\r
-* In xboard, added missing support for WM_DELETE_WINDOW to all\r
-windows. This makes xboard a better citizen, and is much needed with\r
-the newer X window managers that put an [X] button on every window and\r
-bind it to "kill application" if the applicationd does not support\r
-"delete window". We can't allow xboard to be thoughtlessly killed,\r
-since that leaves the chess engine running in the background.\r
-\r
-* We now avoid positioning tops of xboard dialog boxes offscreen.\r
-\r
-* zippy.lines can now use the caret ('^') character as an inter-saying\r
-separator. You no longer need to dig up a text editor that can put NUL\r
-('\000') characters in text files.\r
-\r
-* Bugfix: In traditional chess clock mode, White now gets time added\r
-to its clock as soon as it makes time control. Previously both White\r
-and Black got their time added only when Black made time control,\r
-which would cause some engines to make their 41st move as White too\r
-quickly, thinking they were low on time.\r
-\r
-* The zippyAcceptOnly feature no longer sends a decline command or\r
-a tell. Thus you can use it to put Zippy into a manual accept mode.\r
-\r
-* Bugfix: "tell 50 foo tells you: bar" no longer gets colored as a\r
-personal tell; similarly for "...whispers:" and "...kibitzes:".\r
-\r
-* WinBoard no longer blanks the message line when you start a new\r
-move, unless there was an error message there from the previous move.\r
-\r
-* WinBoard now never puts the white piece drop menu on the middle\r
-mouse button. Both colors are always on the right button. Windows\r
-users often don't think to look for a middle button menu, or don't\r
-really have a working middle button despite what Windows says.\r
-\r
-* Guest login handles on ICC are now parsed again; an ICC wording\r
-change had broken this feature.\r
- \r
-* Autodetect when the engine does not support the "draw" command and\r
-don't relay the command to it in that case. Needed because sending an\r
-unsupported command to GNU Chess makes it move immediately, so people\r
-could make Zippy move without thinking by continually offering a draw.\r
-Thanks to Frank Walker for the problem report.\r
-\r
-* Small changes based on code from Robert Jurjevic: The WinBoard\r
-analysis window can be minimized (though not to the taskbar). The\r
-WinBoard ICS Interaction window will autoscroll if you drag the mouse\r
-above or below the window while selecting, and password entry mode\r
-leaves the entry line as the background color instead of using 75%\r
-gray. Seeks are now colorized with a new color of their own.\r
-\r
-* Added -zippyMaxGames feature.\r
- \r
-* -zippyNoplayCrafty command line option was missing in xboard; fixed.\r
-Thanks to John Perry.\r
-\r
-* Fixed bug in detecting when Zippy loses his bughouse partner.\r
-Thanks to Ben Dean-Kawamura.\r
-\r
-* allobs fix in 4.0.3 didn't work; corrected it.\r
-\r
-* WinBoard will now update the board immediately if a move is made\r
-while the window is being moved or resized.\r
- \r
-4.0.3 -- Sun Aug 15 18:44:39 PDT 1999 Tim Mann\r
-\r
-* Bugfix: moved winboard wizard functions that send a command directly\r
-to the chess engine from Ctrl+Alt+1 and Ctrl+Alt+2 to Alt+1 and Alt+2.\r
-Ctrl+Alt is equivalent to the European AltGr key, so the old assignments\r
-conflicted with typing an @-sign on some keyboards.\r
- \r
-* Bugfix: prevent "If this message stays up, your chess program does\r
-not support analysis" from appearing if AnalysisMode is selected when\r
-already in Analysis or AnalyzeFile mode. Also, deleting analysis window\r
-in WinBoard now switches you to EditGame mode, to avoid the anomaly of\r
-being in an analysis mode with no analysis window present.\r
- \r
-* Change all Zippy environment variables to work as command line\r
-options. For now they still work as environment variables too, but\r
-the environment variables are deprecated.\r
-\r
-* Use unsigned long to hold node counts from engines.\r
-\r
-* Print error instead of crashing on attempts to use xpm or xim pieces\r
-in monochrome mode. Thanks to Jim Torrance for the bug report.\r
-\r
-* Tightened pattern recognition for ICS messages sent to Zippy; should\r
-no longer match ICC allobs output. Fixed recognition of when Zippy is\r
-sent a message; small change to FICS output had broken it.\r
- \r
-* Zippy now exits if the engine dies unexpectedly.\r
-\r
-* Added Zippy "spoofedby" feature; see zippy.README.\r
- \r
-* Narrowed the margins on some older WinBoard dialogs to make their\r
-style uniform with the newer ones.\r
-\r
-* Bugfix: Changing Ponder Next Move from the Options menu did not take\r
-effect until the next game. This bug was in WinBoard only. Thanks to\r
-Stefan Zipproth for the bug report.\r
-\r
-* Got rid of "Internal error: bad move type" message when the engine\r
-makes a move that we can parse but think is illegal. Now the move is\r
-just passed on (which also may be the wrong thing to do).\r
-\r
-4.0.2 -- Thu Feb 25 19:55:32 PST 1999 Tim Mann\r
-\r
-* Added one more built-in sound choice to WinBoard: move.wav from Pete\r
-Galati.\r
- \r
-* Added new larger piece sizes: big, huge, giant, colossal, titanic.\r
- \r
-* Modified the xboard font searcher to be able to use scalable fonts.\r
-The new -fontSizeTolerance flag controls how closely a nonscalable\r
-font must match to be used in preference to a scalable font.\r
- \r
-* Zippy environment variables ZIPPYABORT and ZIPPYADJOURN now control\r
-whether Zippy will accept abort and adjourn requests.\r
-\r
-* We now determine the variant type being played on ICS, send it as a\r
-command "variant VARTYPE" to the chess engine (if in Zippy mode), and\r
-put it in the PGN tags. See engine-intf.txt for variant names. See\r
-ZIPPYVARIANTS in zippy.README to control what variants Zippy will\r
-accept. Note that this now applies to bughouse, too.\r
-\r
-* Zippy now won't do -zippyTalk in a channel unless his handle is\r
-mentioned there.\r
-\r
-* Zippy now ignores bughouse holdings if not actually playing, instead\r
-of stupidly trying to abort the game. Let me know if other strange\r
-things happen when Zippy is observing a game.\r
-\r
-* Set ICS Interaction title bar to "user@server". User name is\r
-determined by parsing message during the login sequence. Zippy now\r
-uses this method to get its name too, so ZIPPYNAME is eliminated.\r
-Problem: with xboard, the title bar gets set to "xterm" upon exit,\r
-since we didn't know what it was to start with.\r
-\r
-* Fixed xboard-only bug in -colorChannel1 command line option. Thanks\r
-to Fredrik Sandstrom for the bug report and fix.\r
-\r
-* Check for overflow of MAX_MOVES. Still not sure this is checked for\r
-everywhere it needs to be.\r
-\r
-* Added .epd to suffixes recognized by WinBoard as position files.\r
-This is a bit of a kludge, as the .fen reading code was not written\r
-with .epd files in mind, but reading them with it is said to work.\r
-\r
-* Added ZIPPYGAMESTART feature, suggested by Jason Hoblit. See\r
-zippy.README.\r
-\r
-* Restored the feature of soaking up the moves from a user-typed "moves",\r
-"oldmoves", or "smoves" ICS command when xboard/WinBoard is idle, but\r
-changed it so that the move list is also echoed to the screen. Some folks\r
-still liked the old feature since it is faster than examine mode, and\r
-printing the moves to the screen should eliminate the confusion it caused\r
-for other people.\r
-\r
-* Bugfix: in WinBoard, starting a click-click move and then clicking on\r
-a black line would cause the source square to be forgotten without taking\r
-the highlight down. Now the errant click is ignored.\r
-\r
-* Corrected shortcut key labels for LoadNext/PrevPosition in WinBoard's\r
-File menu. Thanks to Andreas Stabel for the bug report.\r
-\r
-* Bugfix: if you had a completely full ICS context menu in WinBoard\r
-(90 items), the last one would do nothing if selected.\r
-\r
-* The "computer" engine command added in 4.0.1 was not working; I had\r
-left out part of the code patch. Oops.\r
-\r
-4.0.1 -- Fri Feb 12 21:24:15 PST 1999 Tim Mann\r
-\r
-This is a minor bugfix release. The first item listed below is the\r
-only interesting new feature.\r
-\r
-* You can now type in moves from the keyboard in WinBoard. Either\r
-select TypeInMove from Step menu, or (if you are not in ICS mode),\r
-just start typing. In ICS mode you can type moves into the ICS\r
-interaction window anyway, so I've retained the feature that typing\r
-switches you there. Not implemented in xboard.\r
-\r
-* Removed the "noise 1000" command that used to be sent to the chess\r
-engine when entering analysis modes.\r
-\r
-* Deleted the feature where we soak up the output of a user-typed ICS\r
-"moves" or "oldmoves" command. This ancient feature is not really\r
-useful anymore, now that "examine" exists, and it caused a lot of\r
-complaints.\r
-\r
-* Increased maximum size of ICS text menu to 90 entries and added\r
-overflow checking.\r
-\r
-* The command sent to ICS by Zippy at the end of each game can now be\r
-customized with the ZIPPYGAMEEND environment variable.\r
-\r
-* We treat xboard.info as a pseudo-source since most people don't have\r
-the tools to rebuild it. But "make install" erroneously had a\r
-dependency on it, even though "make all" did not. Fixed.\r
-\r
-* Miscellaneous minor updates and clarifications to engine-intf.txt.\r
-In particular, documented the st and sd commands (support for command\r
-line options -searchTime and -searchDepth), warts and all.\r
-\r
-* Added a small code patch from Bob Hyatt to detect when Zippy's ICS\r
-opponent is a computer and send the command "computer" to the engine.\r
-Added this command to engine-intf.txt. Thanks, Bob.\r
-\r
-* Bugfix: configure was looking for usleep(), but config.h.in didn't\r
-have an entry for it, so HAVE_USLEEP was never defined. Also, in the\r
-non-HAVE_USLEEP case, there was a possible race condition between the\r
-signal handler and the pause() call. Thanks to Ben Dean-Kawamura for\r
-the bug reports.\r
-\r
-* Bugfix: a "1..." preceding Black's first move (usually present if\r
-there is a comment on White's first move) would cause the parser\r
-to think a new game started there and report "End of game" on the\r
-current game. Thanks to Dell Garner for the bug report.\r
-\r
-* Changed the abbreviation for -searchDepth from -sd to -depth to fix\r
-a clash with -secondDirectory.\r
-\r
-* Changed -searchDepth to be orthogonal to the various timing options.\r
-Previously it would search for an unlimited time to the given depth;\r
-now the engine is allowed to choose its search time in the normal way,\r
-but is told to cut off the search early if it reaches the given depth.\r
-\r
-* Bugfix: SaveSettings in WinBoard was saving both the long form\r
-option highlightSquareColor and its abbreviation (hsc).\r
-\r
-* Fixed a redisplay bug in DisplayBothClocks that could cause White's\r
-clock to be highlighted in EditPosition mode when Black's should have been.\r
-\r
-* Fixed Zippy's feature of passing on draw offers from the ICS opponent.\r
-The colorization code was eating the offer before Zippy saw it, so I disabled\r
-colorization of offers while in -zp or -zt mode. (Other types of\r
-colorization are already disabled in Zippy mode for similar reasons.)\r
-\r
-* Added some more commands to the default ICS context menu in WinBoard,\r
-and put "(name)" on the ones that insert a playername (or game number).\r
-\r
-* Added missing documentation to WinBoard help file: PonderNextMove, the\r
--ponder/-xponder argument, and the up/down arrow history feature in the\r
-ICS Interaction window.\r
-\r
-* Fixed ZIPPYNOPLAYCRAFTY feature to fire only if the opponent is Crafty,\r
-not if some other Crafty is observing the game and kibitzes.\r
-\r
-* Fixed bugs in generating "partner" commands when Zippy is playing\r
-bughouse.\r
-\r
-4.0.0 -- Sat Jun 20 16:59:47 PDT 1998 Tim Mann\r
-\r
-* Fixed WinBoard resizing so that the edges you do not drag remain in\r
-place, even when the final size is different from what you dragged to.\r
-(This doesn't work on NT 3.51 or earlier, if anyone cares.)\r
-\r
-* Fixed problems with resizing WinBoard on Windows NT: you no longer get\r
-whitespace around the board, a clipped board, or a lot of flashing during\r
-the drag.\r
-\r
-* Added customization for highlight-square color.\r
-\r
-* Bugfix: backend.c wrote to stderr in a few obscure places, which doesn't\r
-work in WinBoard.\r
-\r
-* Added Index Number field back to LoadGame/LoadPosition dialog boxes in\r
-WinBoard. This required some extra code to work with both the\r
-Explorer-style dialog boxes and the old-style NT 3.51 dialog boxes. Ugh.\r
-\r
-* WinBoard startup dialog now understands -zp mode. The first chess\r
-engine selector is enabled and the value is used.\r
-\r
-* Bugfix: ResetGame would send "exit" to engine twice if it was in an\r
-analysis mode.\r
-\r
-* Bugfix: The response "Illegal move: bk" to the "bk" command, indicating\r
-that it is not implemented, would confuse xboard.\r
-\r
-* Bugfix: Ignore empty hints ("Hint:\n") instead of printing a message\r
-saying that some bogus string (often "Hint:") is illegal.\r
-\r
-* Bugfix: LoadNextGame/LoadPreviousGame/ReloadSameGame were broken.\r
-\r
-3.6.12 -- Sat Jun 13 14:57:10 PDT 1998 Tim Mann\r
-\r
-Beta test release of xboard and WinBoard.\r
-\r
-* Spruced up xboard man page a bit.\r
-\r
-* Added Highlight Last Move to xboard too.\r
-\r
-* The revamped xboard mouse click code had several more bugs than the\r
-previous version, so I revamped it again. All fixed now, I hope.\r
-\r
-* xboard bugfix: crash in CreatePieceMenu.\r
-\r
-* Oops. winboard-3_6_11beta.exe installed 3.6.10beta, not the new version.\r
-\r
-3.6.11 -- Fri Jun 12 20:00:48 PDT 1998 Tim Mann\r
-\r
-Beta test release of xboard and WinBoard.\r
-\r
-* Major reorganization to engine-intf.txt. Some new features added,\r
-many existing features clarified and hints for engine programmers added.\r
-Support for new features added to program.\r
-\r
-* Changed defaults for -scp (etc.) back to being independent of -fcp, as\r
-in 3.6.2. That is, the default is no longer to copy the value from -fcp if\r
--scp is not specified. This will sometimes make command lines longer but\r
-will remove some confusing situations.\r
-\r
-* Split -reuseChessPrograms into two options: -reuseFirst and\r
--reuseSecond. Fixed obscure bugs when reuse is off.\r
-\r
-* Detect ICC and change some command usage slightly there: only ICC has\r
-set-quietly; only FICS has iset and bsetup clear. With this feature, we\r
-can now safely use bsetup clear when appropriate instead of deleting each\r
-piece one by one.\r
-\r
-* Added indent to lines that are wrapped by WinBoard ICS Interaction\r
-window. This seems to tickle a Microsoft bug in the RichEdit control:\r
-occasionally the start of the next line after the wrapped line is indented\r
-too. I think the wrapped indent feature is useful enough that it's worth\r
-having in spite of the bug.\r
-\r
-* WinBoard bugfix: bounding box for the board was computed incorrectly by\r
-mouse code. It would think you moved off the bottom of the board before\r
-you really did, so it was hard to drag pieces along the bottom rank on\r
-smaller board sizes.\r
-\r
-* Fixed obscure parser.l bug: ambiguity between capture using : instead of\r
-x and email header line. Also removed or simplified a lot of complex\r
-patterns for English (as opposed to PGN) end-of-game indications while I\r
-was in there.\r
-\r
-* Added PonderNextMove option.\r
-\r
-* xboard EditPosition piece menus now let you set the side to play by\r
-selecting the "White" or "Black" label at the top of the menu, like\r
-WinBoard. (Both xboard and WinBoard still let you set the side to play by\r
-clicking on the clock.)\r
-\r
-* Merged documentation of Crafty and GNU Chess thinking output in\r
-engine-intf.txt. Corrected code in backend.c to match documentation; it\r
-used to require the PV to start in column 27 (!).\r
-\r
-* Fixed bug that caused crashes in "-reuseChessProgram false" mode.\r
-\r
-* Draw by agreement in Two Machines mode now works as it is supposed to.\r
-Other minor bugs in handling game end messages from machines are also\r
-fixed, and engine-intf.txt is revised in this area.\r
-\r
-* Revamped xboard code for handling mouse clicks on the board. In\r
-particular, it had a bug if a click-click promotion move was made.\r
-\r
-* Fixed and reinstated optimization for << in analysis modes: send\r
-initString and re-send the board if needed. Sending repeated undos\r
-is bad because Crafty prints some analysis after every one.\r
-\r
-* Don't go into a spin loop while pausing between xboard animation frames.\r
-This caused problems, especially when compiling with -O2 on HP-UX.\r
-\r
-* WinBoard Options/Colors/RevertToDefaults now also turns off Monochrome\r
-if it was on, and similarly for Options/ICSInteractionColors/RevertToDefaults.\r
-This seemed to confuse people before.\r
-\r
-* Bugfix: ICS Interaction context menu items with neither of the two\r
-optional flags set did not work.\r
-\r
-* Bugfix: PGN move numbers are optional, but we were insisting on "1"\r
-right after the tags.\r
-\r
-* Bugfix: only the first game of an -mg match was loading -lpf or -lgf.\r
-\r
-* Other minor fixes and code cleanup.\r
-\r
-3.6.10 -- Mon Jun 1 01:32:31 PDT 1998 Tim Mann\r
-\r
-* Added ZIPPYNOPLAYCRAFTY feature; see zippy.README.\r
-\r
-* Added timestamps for chess engine interaction to -debug output.\r
-\r
-* Now allow 10 seconds (was 5) between games in match mode for engines to\r
-respond to "force" command that ended previous game.\r
-\r
-* When a game is picked from the game list and the names of White and\r
-Black are known, display them in the window banner instead of the filename\r
-and game number.\r
-\r
-* Changed default for -scp and -sd to be the values of -fcp and -fd.\r
-\r
-* Added boxes for both engines to WinBoard startup dialog. Changed to\r
-dropdown boxes whose content can be set from winboard.ini, similar to\r
-the box for ICS name.\r
-\r
-* Accept "offer draw" (or "*offer*draw*") from engine to offer a draw.\r
-\r
-* Accept "move mmmm" from engine as well as silly "1. ... mmmm" syntax.\r
-\r
-* Added support for bughouse engines (Zippy mode only).\r
-\r
-* Move bombproofing for engines sending illegal or out of turn moves.\r
-\r
-* Always send "xboard\n" to engine as first command. Eliminates need\r
-to run crafty as "crafty xboard".\r
-\r
-* Rewrote xboard code for input from engines to fix longstanding bugs.\r
-Previously an engine that sent one line in two separate writes with \r
-some time lapse in between (or perhaps that sent several lines in one\r
-write) could make xboard hang. WinBoard did not have this bug.\r
-\r
-* Fixed minor bugs in dealing with illegal moves.\r
-\r
-* Added "iset startpos 1" for FICS.\r
-\r
-* Removed special support to put "GNU Chess" or "Crafty" in the window\r
-banner instead of the engine's base filename. This gives a more level\r
-playing field for other engines. Also fixed bugs in the code that finds the\r
-engine's base filename.\r
-\r
-* Bugfix: Abort or Resign at the very start of a game in chess engine mode\r
-would fail to send "force" to the engine.\r
-\r
-* Fixed some minor bugs in new "result" messages, and changed format to\r
-include a trailing PGN comment giving the reason the game ended.\r
-\r
-* Changed syntax of /font options in WinBoard; old syntax was assuming\r
-that a font name can't contain a digit, which is wrong. Old font names in\r
-WinBoard.ini files are still accepted.\r
-\r
-* Serious further work on getting WinBoard to read/write files in the\r
-"right" directories and documenting exactly what it does.\r
-\r
-* Added LoadPreviousPosition, LoadNextPosition, ReloadSamePosition.\r
-\r
-* Misc. tiny fixes and cleanup.\r
-\r
-3.6.9 -- Sun May 24 20:53:08 PDT 1998 Tim Mann\r
-\r
-xboard and WinBoard beta release.\r
-\r
-* Tightened up illegal move handling. Illegal or meaningless moves from a\r
-file or chess engine should no longer get translated into a1a1 and blindly\r
-applied. Explicit moves to the same square (like a1a1) no longer make the\r
-piece on that square capture itself and vanish.\r
-\r
-* Added AlwaysOnTop feature to winboard.\r
-\r
-* Fixed bug in winboard "@" command line indirection operator.\r
-\r
-* Removed buggy "optimization" code for ToStart in analysis modes.\r
-\r
-* Fixed typo bug in zippy.c that would often cause winboard to crash\r
-right after starting a game in -zp mode.\r
-\r
-3.6.8 -- Sat May 23 22:23:19 PDT 1998 Tim Mann\r
-\r
-xboard and WinBoard beta release.\r
-\r
-* Added -firstDirectory and -secondDirectory so that chess engines can\r
-be started in a different directory from xboard/WinBoard itself.\r
-\r
-* Added -matchGames to allow more than one game in -matchMode. The games\r
-are played with colors alternating between the two chess engines. Had to\r
-add a time delay at the end of each game to catch up with game ending\r
-messages from both chess engines -- yuck.\r
-\r
-* Changed TwoMachines mode to have firstChessProgram play White by\r
-default. Added -firstPlaysBlack to restore old behavior.\r
-\r
-* Major rework of code in backend.c for dealing with first and second\r
-chess engines. Generalized the code and created a struct type with one\r
-instance for each engine. Several small bugs fixed along the way. \r
-\r
-* Fixed bugs in Abort in local chess engine mode.\r
-\r
-* Tightened pattern matching to recognize moves from machine. Should cure\r
-bogus "Illegal move" errors while Crafty is pondering with Show Thinking\r
-on, among other things.\r
-\r
-* WinBoard keeps focus in board window after popping up a comment due to\r
-Forward/Backward/ToStart/ToEnd commands.\r
-\r
-* Finally got rid of warnings on compiling moves.c under Windows.\r
-\r
-* Fixed so WinBoard will compile on machines where WM_MOUSELEAVE is not\r
-defined.\r
-\r
-* Removed various bits of unused code.\r
-\r
-* Parse (and ignore) NAGs in PGN files.\r
-\r
-* Updated engine-intf.txt.\r
-\r
-* Send "result R" to the chess program at the end of each game, where\r
-R is the PGN result 1-0, 0-1, 1/2-1/2, or *.\r
-\r
-* Bugfix: suppress animation when loading a game with timeDelay=0.\r
-\r
-* Bug fix: pondering output from Crafty that contained "..." could be\r
-mistaken for a move, causing bogus error messages and general chaos.\r
-\r
-* xboard "make clean" bug fix: moved things created by configure to be\r
-removed only by "make distclean".\r
-\r
-* Fixed a remaining case where move was being animated before being\r
-relayed to opponent.\r
-\r
-* Backend was reversing time/otim commands to the chess program (new bug),\r
-and was often not sending them on the first move of a game or the first\r
-move after a mode change (old bug). Fixing the latter required a kludge\r
-to work with both GNU Chess and Crafty, because Crafty swaps white and\r
-black clock times when it swaps sides, while GNU Chess does not. The\r
-kludge is that we always make sure the chess engine thinks its opponent is\r
-on move before we set the clock. This will sometimes result in sequences\r
-like "white\ntime xxx\notim yyy\nblack\ngo", or the same with white and\r
-black interchanged.\r
-\r
-* Removed last trace of old -whiteString and -blackString arguments.\r
-\r
-* Fixed so that you can type "bd" into the Direct Command dialog when\r
-debugging gnuchess, without having xboard parse the clock display\r
-(starting with "White") as "White wins" and end the game.\r
-\r
-* Changed moves.c to make a distinction between IllegalMove (where we\r
-could tell what move was intended, but it violates the chess rules) and\r
-MeaninglessMove (where we could not tell). This is a step towards getting\r
-rid of cases where we translate meaningless moves into "a1a1", but some\r
-work is probably needed to track them all down.\r
-\r
-* Fixed bug in WinBoard monoMode dragging.\r
-\r
-* Changed WinBoard to new style file dialogs. In the process, disabled\r
-the feature that let you enter the index number of a game or position within\r
-the file in the dialog. This is no loss in LoadGame, as you can pick your\r
-game from the game list dialog that follows, but it does remove some\r
-functionality from LoadPosition.\r
-\r
-3.6.7 -- Mon May 18 21:25:00 PDT 1998 Tim Mann\r
-\r
-xboard and WinBoard beta test release. I've been unable to reproduce some\r
-reported drawing bugs, so they may still not be fixed.\r
-\r
-* Changed PopUpErrors option to PopupMoveErrors, which is more useful, and\r
-changed default to off. Errors other than move errors should always be in\r
-popups; they are often too big for the message area and too important to\r
-put where they can be easily missed. But it seems good to get rid of the\r
-popups for move errors by default.\r
-\r
-* xboard analysis window no longer forces itself to top whenever there is\r
-new output. Also, now uses built-in Xaw word wrapping instead of trying\r
-to do its own; works better.\r
-\r
-* Bugfix: Reset did not take Crafty out of analyze mode.\r
-\r
-* A chess engine no longer has to claim to be Crafty to be able to use\r
-AnalysisMode and AnalyzeFile; it just has to implement the analyze\r
-command as Crafty does. Put in heuristics to generate more informative\r
-error messages if the engine does not support analyze, and checked that\r
-they work at least with GNU Chess.\r
-\r
-* Added click-click moving, HighlightLastMove, and HighlightDragging to\r
-WinBoard. The highlight features are unlikely to go into xboard unless\r
-the xboard drawing code is cleaned up to do *all* drawing on the board\r
-from DrawPosition, as WinBoard does. This is low priority for me.\r
-\r
-* Eliminated bogus "Error gathering move list: no header" popup. You\r
-could get this by observing two fast games at once without turning off\r
-GetMoveList.\r
-\r
-* Disable WinBoard Sounds menu entirely in -ncp mode, since not even\r
-MoveSound is used in that mode.\r
-\r
-* WinBoard bugfix: Several problems were caused if the user changed \r
-WinBoard's current directory in a Load, Save, or Browse dialog. In\r
-particular, WinBoard.ini would get saved in the wrong directory, and\r
-sound .wav file names would not get saved with a full pathname. I think\r
-all such problems are now fixed.\r
-\r
-* WinBoard bugfix: iconizing the board after an aborted mouse resize would\r
-(partially) resize it to Tiny.\r
-\r
-* WinBoard bugfix: board was not being drawn in color on 256-color\r
-displays. This bug was introduced in 3.6.6.\r
-\r
-3.6.6 -- Tue May 12 17:43:43 PDT 1998 Tim Mann\r
-\r
-xboard and WinBoard beta release. Note: not all reported bugs are fixed.\r
-\r
-* Move animation in WinBoard, programmed by Henrik Gram. Great stuff!\r
-\r
-* Animate backward moves too.\r
-\r
-* xboard bugfix: -font (and friends) can now specify a font alias (such\r
-as "fixed"), not just a full X Consortium name pattern. Previously this\r
-would give a resource conversion error message.\r
-\r
-* Some coding style cleanup in xboard.c.\r
-\r
-* Earlier error check for moving wrong color piece in EditGame mode.\r
-\r
-* Completed fix to pattern matching; see 3.6.5.\r
-\r
-* Fixed some software rot bugs in Zippy.\r
-\r
-* Split AnimateDragging as separate option from AnimateMoves.\r
-\r
-* Added FlashMoves to options menu and -flash/-xflash to command line\r
-options (xboard only).\r
-\r
-* Some preliminary work on visible bughouse holding support. Most of the\r
-code is not present in this release because I have not gotten it working\r
-properly yet; my first approach went down a blind alley and I had to\r
-remove most of the partially working code in preparation for a rewrite.\r
-\r
-3.6.5 -- Fri May 8 14:22:09 PDT 1998 Tim Mann\r
-\r
-Not generally released.\r
-\r
-* Pack bughouse holdings display in banner more tightly when board is one\r
-of the smaller sizes (when smallLayout or tinyLayout is true, that is).\r
-An interim measure, but should help.\r
-\r
-* Completed fix to make move list parsing recognize the end condition and\r
-final comment.\r
-\r
-* Fixed pattern matching for chatter (tells, etc.) to be more reliable.\r
-This should reduce the incidence of colors starting in the wrong place and\r
-of incorrectly matching things that look like other patterns inside\r
-chatter, such as "shout <12>". (These errors were already rare.)\r
-\r
-* WinBoard now lets you customize the list of ICS's in the startup dialog.\r
-For now, at least, requires editing WinBoard.ini with a text editor.\r
-\r
-* Bug fix: WinBoard window sizing and position setting save/restore did\r
-not work right when the taskbar was at the top (or left side) of the\r
-screen and not in autohide mode.\r
-\r
-* Merged xboard click/click mode and drag mode, and deleted\r
-ClickClickMoving option on menu. Now if you click on a piece, it\r
-highlights and a further click on another square will move it. (A second\r
-click on the same square takes down the highlight.) Or if you press down\r
-on a piece and start to drag, you can drag it to a new square.\r
-\r
-* When making click/click style moves, if your second click is on a piece\r
-of the same color, instead of saying "Illegal move", we now cancel the first\r
-starting square, replace it with the second, and wait for another click to\r
-finish the move.\r
-\r
-* Separate -secondInitString. Default: same as -initString. Suggested by\r
-Remi Coulom.\r
-\r
-* Patch from Frank McIngvale to make animation work with XIMs. Yay!\r
-\r
-* Changed move animation to happen after move is passed on to ICS or the\r
-chess engine, where applicable. Fixed problems with updating moveList\r
-that this uncovered.\r
-\r
-* Changed game list to show PGN result token for each game.\r
-\r
-* The usual minor bug fixes.\r
-\r
-3.6.4 -- Thu Apr 30 23:14:43 PDT 1998 Tim Mann\r
-\r
-xboard and WinBoard beta test release.\r
-\r
-* xboard documentation updated, both man page and info file. An attempt\r
-to generate both from the same source with LinuxDocSGML was abandoned, at\r
-least for now. WinBoard doc updated too.\r
-\r
-* Merged updates to animation code from Hugh. Fixed a couple of remaining\r
-bugs, mostly to do with handling Pause mode correctly.\r
-\r
-* Added SaveSettingsOnExit to WinBoard.\r
-\r
-* WinBoard now saves the last screen position of the Comment, Edit Tags,\r
-Game List, and Analysis windows (in addition to the board and ICS\r
-Interaction windows) in WinBoard.ini.\r
-\r
-* WinBoard now provides a way to customize the right-button context menu\r
-in the output area of the ICS Interaction window. For now, requires\r
-editing WinBoard.ini with a text editor. \r
-\r
-* Various minor fixes to ICS message recognition, most affecting only Zippy.\r
-\r
-* Colorize the notification when someone sends you a message while you are\r
-logged in, not the output of the "messages" command.\r
-\r
-* Fixed colorization to turn off at the right place more reliably.\r
-\r
-* Added a new color and WinBoard sound for "requests": abort, adjourn,\r
-draw, pause, and takeback. The same color and sound are used for all of\r
-these.\r
-\r
-* Added GUI to change sounds in WinBoard.\r
-\r
-* Suppressed WinBoard error popup when a sound can't be played. They were\r
-popping up when two separate WinBoards tried to play a sound at the same\r
-time (such as during a bughouse match).\r
-\r
-* Fixed WinBoard crash when a sound file didn't exist.\r
-\r
-* WinBoard ports of timestamp and timeseal now produce decent error\r
-messages if they fail to connect, and WinBoard captures the messages and\r
-puts them into a popup. Previously WinBoard would exit with no message on\r
-such errors.\r
-\r
-* WinBoard resizing with mouse improved; now accurately picks the largest\r
-size that fits in the new area.\r
-\r
-* Added option to turn off error message popups.\r
-\r
-* Added sizes slim, dinky, and teeny.\r
-\r
-* Fixed some minor problems with error message wording.\r
-\r
-3.6.3 -- Mon Feb 23 19:08:57 PST 1998 Tim Mann\r
-\r
-xboard beta test release only. Man page is updated for the changes, but info\r
-file is not.\r
-\r
-* Bug fix: LoadGame could not load a PGN game whose first move was\r
-castling (which is possible from setup positions).\r
-\r
-* Bug fix: we were ignoring illegal move messages from chess engines in\r
-modes where the engine is refereeing but not participating (EditGame,\r
-LoadGame, AnalyzeFile). The problem was in a workaround for a Crafty bug,\r
-where Crafty generates a bogus illegal move message if a "." (used by\r
-the PeriodicUpdates feature) is sent in analysis mode when the current\r
-analysis reveals a forced mate. Installed a different workaround (that\r
-works in most but not all cases) and reported the Crafty bug. Bob Hyatt\r
-replied with a fix, so the Crafty bug should be gone in Crafty 14.12 or so.\r
-\r
-* WinBoard only: enabled resizing board with the mouse. It snaps to the\r
-nearest (but not too much larger) predefined size.\r
-\r
-* The xboard default font is now sized according to piece size, just as\r
-clockFont and coordFont have always been.\r
-\r
-* Added more sizes: bulky, moderate, average, middling, mediocre, petite.\r
- \r
-* xboard only: Added Animate Moves and Click-Click Moving to Options menu. \r
-\r
-* xboard only: Added code to animate piece movement, from Hugh Fisher.\r
-\r
-* New feature: autoflag is implemented in MachineWhite, MachineBlack, and\r
-TwoMachines modes. If it is on and either a chess program or the user\r
-oversteps his time, xboard will automatically call the flag and end the\r
-game. This feature was requested by someone who runs matches between\r
-programs and wants to penalize GNU Chess for its habit of running slightly\r
-over at the end of a time control. I personally think it's pointless.\r
-\r
-* Fixed a bug in Zippy's pattern matching; he can now reply to ICC\r
-messages again.\r
-\r
-* Generate prettier notation for illegal moves. If a move is illegal only\r
-because it leaves the player in check, generate notation as if that were\r
-not illegal. For instance, if two knights are a knight's move away from\r
-f3, one on g1 and one on e5 that is pinned, the notation would be Nf3 to\r
-move the g1 knight, Nef3 to move the e5 knight. (Suggested by Philippe\r
-Schnoebelen.) In addition, if a move is illegal because the type of piece\r
-moved cannot go that way, would be jumping over another piece, etc., we\r
-give fully disambiguated coordinate notation; for example, Ng1g3, Ke1xe8,\r
-d2xd8=Q, etc. An alternative would be to still write Ng3 if there is only\r
-one knight on the board, or Ngg3 if the other knight is not on the g file,\r
-but life is too short to code up all this stuff, and perhaps the way I did\r
-it is better as it emphasizes that this move was really made despite being\r
-illegal. I wonder if the new PGN standard revision will speak to notation\r
-of illegal moves?\r
-\r
-* Fixed gross bug from 3.6.2: if a chess program said "checkmate" and\r
-White was left on move, the PGN outcome was "1-0 {Black mates}" instead\r
-of "0-1 {Black mates}"! The bug occurred only for that specific string.\r
-\r
-3.6.2 -- Wed Jul 23 16:47:29 PDT 1997 Tim Mann\r
-\r
-* There was a bug in backing up from the end of a game against a chess\r
-engine, introduced when -reuse mode was added. Fixed.\r
-\r
-* Recognize "{" as terminating an ICS move list. Previously we needed to\r
-see a prompt (containing %), but occasionally ICC can send more stuff\r
-right after a move list with no prompt in between.\r
-\r
-* In WinBoard, -mm now implies -cp, so you don't get the startup dialog.\r
-\r
-* WinBoard startup dialog no longer sets -scp. People used to get\r
-confused because they would give the -fcp and -scp arguments, but omit\r
--cp. This would bring up the startup dialog, which would set both -fcp\r
-and -scp to the value in the engine name box. Now you can change -scp\r
-only with the command-line argument. That will confuse some people too,\r
-but hopefully fewer. I think overall it's better than putting spaces for\r
-both -fcp and -scp in the dialog, which would puzzle newbies.\r
-\r
-* Bug fix: Analyze File mode now works in WinBoard.\r
-\r
-* Bug fix: WinBoard window no longer cuts off part of the bottom row if\r
-the menu bar wraps to a second line.\r
-\r
-* Accept game end messages of the form "PGN-result {comment}" from the\r
-chess engine, where PGN-result is 0-1, 1-0, or 1/2-1/2. Accept "resign"\r
-or "computer resigns" from the chess engine as a synonym for "0-1 {White\r
-resigns}" or "1-0 {Black resigns}". Accept any message from the chess\r
-engine containing "game is a draw" as a synonym for "1/2-1/2 {Draw}".\r
-Accept "White resigns" or "Black resigns".\r
-\r
-* Enable "Action / Draw" menu item in chess engine mode. It sends the\r
-command "draw" to the engine. Accept any message from the chess engine\r
-containing "offers a draw" as a draw offer. WARNING: Draw offers from the\r
-user and the engine (or from two engines) are not yet matched up by xboard\r
-in chess engine mode. Two engines could get into a loop offering each\r
-other draws.\r
-\r
-* Bug fix: Game end messages from the chess engine are always ignored in\r
-Zippy mode. Previously they could sometimes be processed, which was\r
-sometimes making Zippy hang at the start of a new game that followed\r
-quickly after an old one.\r
-\r
-* Zippy can now respond to titled players in channels. Zippy will avoid\r
-talking to himself in a channel if he knows his own name.\r
-\r
-* Bug fix: in colorization arguments, the bold setting was being ignored\r
-if the background color was defaulted. (xboard only.)\r
-\r
-* Extended ParseFEN to accept Crafty 12.2's interpretation of FEN.\r
-If fewer than 8 squares are given in a row, or fewer than 8 rows are\r
-given, the uncovered squares are empty. Also, there can be a / after the\r
-8th row.\r
-\r
-3.6.1 -- Sat May 17 01:02:33 PDT 1997 Tim Mann\r
-\r
-* Bug fix: Hitting escape while entering a password on WinBoard no longer\r
-sets the font color back to black (which made further typing visible).\r
-\r
-* Bug fix: On Windows NT 4.0, WinBoard /ics /icshelper=timestamp would\r
-often hang if you tried to exit with the Exit menu item, the [X] button,\r
-etc. The same fix may also have corrected the problem where running a\r
-chess program with /xreuse would sometimes crash Windows 95 (but not NT)\r
-when the chess program was killed and quickly restarted.\r
-\r
-* Bug fix: Periodic Updates would not work if turned on after having been\r
-off. Also, the default was needlessly "off" in WinBoard.\r
-\r
-* Zippy bug fix: Continuing an adjourned game was totally broken. The\r
-wrong moves, or no moves at all, were being fed to the chess program.\r
-\r
-* WinBoard change: Giving -ics without -icshost now pops up the startup\r
-dialog with "Use an Internet Chess Server" pre-selected, so that you get a\r
-menu of chess servers instead of going directly to ICC.\r
-\r
-* Bug fix: WinBoard's SaveSettings was saving -icshost, -icsport, and\r
--icshelper in winboard.ini. This causes a problem if you use a different\r
-icshost later that needs the default values for icsport (5000) and\r
-icshelper ("", meaning none).\r
-\r
-* Disabled complaints about unexpected "[Ii]llegal move" messages from\r
-the chess program; we still get them at times.\r
-\r
-* Greatly simplified the code for Move Now and SIGINT (ATTENTION). Fixes\r
-the bug where Move Now did not work with GNU Chess in WinBoard, and\r
-several more obscure bugs as well. Reintroduces a minor bug: GNU Chess might\r
-not think on your time after a Move Now command. Trying to fix this\r
-causes too many other problems. Documented change in engine-intf.txt.\r
-\r
-* Cleaned up code for obtaining ratings from ICS. It was kludgey and may\r
-have had bugs on systems with no "Creating:" message. It should fail\r
-gracefully there, just not finding the ratings.\r
-\r
-3.6.0 -- Thu May 8 19:55:58 PDT 1997 Tim Mann\r
-\r
-* WinBoard now has right-button context menus in the ICS Interaction\r
-window. Some of the items do immediate commands on the player name you\r
-have selected or pointed to. (Suggested by Paolo Casaschi.) Also, the\r
-middle button or shift+right does a immediate Copy and Paste.\r
-\r
-* Fixed a bug in Zippy's wild rejection. The bug was causing Zippy to\r
-reject all forms of wild. Now it rejects only 1, 9, 16, 17, and 24, as\r
-was intended. These variants have different rules, while the other\r
-variants defined so far only have different starting positions.\r
-(Actually, wild 2, 3, and 4 never allow castling, but may sometimes by\r
-chance have king and rook start on squares where castling appears legal.\r
-This could cause a problem later.)\r
-\r
-* Zippy now resumes adjourned games by feeding the chess program \r
-the move list instead of the position. Setting -getMoveList to False \r
-restores the old behavior. Feeding in the move list is better because \r
-it enables the chess program to correctly handle en passant legality, \r
-castling legality, draw by repetition, and draw by the 50 move rule. \r
-\r
-* Added a WinBoard startup dialog for people who run WinBoard.exe without\r
-using the Start menu or reading the help file. Instead of being dumped\r
-directly into GNU Chess mode, you now get a menu of choices. You now have\r
-to give the new WinBoard -cp option to go directly into chess engine mode.\r
-I did not add this feature to xboard.\r
-\r
-* Handling of "illegal move" from Crafty is now back on. (It was turned\r
-off in 3.4.6; see below.) Crafty 12.0 doesn't seem to send bogus ones\r
-anymore. I did have to suppress sending time and otim in analyze mode to\r
-make this work, but there is no harm in that.\r
-\r
-* Zippy now sends "gameend" to ICS at the end of each game. You can alias\r
-this to "seek" or whatever you like.\r
-\r
-* Added Crafty support for Move Now, using the "?" command. We test\r
-whether this command exists by trying it once at the start of the first\r
-game, before it really makes sense. If we don't get a message like\r
-"Illegal move ... ?", we assume it's OK. (We're careful about this\r
-because sending a "?" to GNU Chess on Move Now keeps it from pondering the\r
-next move as it should.)\r
-\r
-* Added support for a tellusererror command from the chess engine. See\r
-engine-intf.txt.\r
-\r
-* Attempted to make engine-intf.txt complete.\r
-\r
-* Minor fixes/cleanup to GameEnds code, to be sure we always interrupt\r
-when needed, and always undo an extra move generated by stopping the chess\r
-program while it is thinking.\r
-\r
-3.5.7 -- Sat May 03 22:37:44 PDT 1997 Tim Mann\r
-\r
-Beta release of both xboard and WinBoard.\r
-\r
-* Updated xboard documentation. I really wish the man page was built from\r
-the info file instead of being separate! It's a pain to update them both.\r
-\r
-* Updated documentation of the interface between XBoard/WinBoard and chess\r
-programs, and renamed it to engine-intf.txt.\r
-\r
-* Added support for tellics, telluser, and askuser commands from the chess\r
-engine. See engine-intf.txt.\r
-\r
-* Various bug fixes. On WinBoard, 256 color displays are finally handled\r
-right; no more color flashing when you switch windows unless the colors\r
-really need to be updated. Also, I think the problem of the console font\r
-failing to change or changing back by itself is finally fixed.\r
-\r
-3.5.6 -- Tue Apr 29 03:08:00 PDT 1997\r
-\r
-Beta release, WinBoard only. ChangeLog was out of date in release,\r
-updated here.\r
-\r
-* Added ICC timestamp and FICS timeseal to WinBoard distribution. These\r
-are my own ports to Win32, based on and used by permission of the owners\r
-of the proprietary source code (Daniel Sleator for timestamp, Henrik Gram\r
-for timeseal). The owners permit these programs to be distributed only in\r
-binary form (to help prevent cheating), so to avoid running afoul of the\r
-GPL, I have kept them as separate programs, not linked into the WinBoard\r
-address space. Updated Start menu icons to use them.\r
-\r
-* Miscellaneous smaller changes.\r
-\r
-3.5.5 -- Fri Apr 25 03:06:00 PDT 1997\r
-\r
-Beta release, WinBoard only. ChangeLog was out of date in release;\r
-updated here.\r
-\r
-* Added simple sound support to WinBoard.\r
-\r
-* Updated WinBoard documentation.\r
-\r
-* Internal implementation of the telnet protocol is now more complete.\r
-You can now hop through a VMS host on the way to ICS. For example, do\r
-"xboard -ics -icshost vms.host.edu -icsport 23", then log in. Do not use\r
-the -telnet flag; that says to use an *external* telnet program. To avoid\r
-double echoes, you need to force character mode in VMS telnet after\r
-connecting from VMS to ICS. Do "^]^Mset mode char^M^M".\r
-\r
-* Display opponent names in the title bar for MachineWhite, MachineBlack,\r
-and TwoMachines modes.\r
-\r
-* WinBoard now has an installer, built with InstallShield. The installer\r
-works with a binary-only distribution. Sources are still freely\r
-available, but now separately.\r
-\r
-* Added SaveSettings to WinBoard, which saves current option settings to\r
-winboard.ini. Made sure all options can be saved and loaded, including\r
-fonts and com port settings.\r
-\r
-* If the game ends while you are dragging a piece, we now don't let you\r
-finish the move. Formerly the move was accepted and your opponent's clock\r
-would start running again.\r
-\r
-3.5.4 -- Fri Apr 18 01:15:24 PDT 1997 Tim Mann\r
-\r
-Beta test release of WinBoard and xboard. The documentation remains\r
-out of date.\r
-\r
-* Many fixes and improvements to new WinBoard user interface code.\r
-\r
-* In Zippy mode, avoid sending another copy of the same move to the chess\r
-program if ICS sends us another copy of the board image. Hard to believe\r
-it took me until now to diagnose and fix this problem!\r
-\r
-3.5.3 -- Sat Apr 12 19:49:33 PDT 1997 Tim Mann\r
-\r
-Beta test release of WinBoard and xboard.\r
-\r
-* Fixed fatal bug in WinBoard input handling.\r
-\r
-* Made code to stop chess program for reuse a bit smarter. Removed kludge\r
-of "white" in initString; it didn't work well, and is unneeded\r
-with Crafty 11.21 and later.\r
-\r
-3.5.2 -- Sat Apr 12 15:40:01 PDT 1997 Tim Mann\r
-\r
-Beta test release of WinBoard.\r
-\r
-* Ignore check and permit promotion to King during suicide games; no need\r
-to turn off TestLegality.\r
-\r
-* Renamed CheckLegality to TestLegality to avoid confusion with the chess\r
-term "check".\r
-\r
-* Added Rematch to Action menu.\r
-\r
-* WinBoard now has a custom ICS interaction window with scrollback, a\r
-separate line for input, and colorization. Accelerators that conflict\r
-with normal editing keys were changed (by requiring Alt+) so they can work\r
-in both the console and the main window.\r
-\r
-* WinBoard error popups are now non-modal and disappear when you make a\r
-new move, as in xboard.\r
-\r
-* Configure now defaults to --disable-ptys on all systems. If anyone has\r
-an ancient SysV system where pipes don't work with select, they can still\r
-do "configure --enable-ptys" explicitly. I would appreciate getting a bug\r
-report if this happens to anyone, with complete output from configure and\r
-"uname -a".\r
-\r
-* "make install" now makes the installation directories too.\r
-\r
-* Fixed a bug that would cause an "Illegal move" message for Black from\r
-GNU Chess to be incorrectly considered bogus.\r
-\r
-* Handle name changes during an ICS game (FICS bname and wname commands).\r
-\r
-* You can force both chess programs to be killed at the end of each game\r
-by turning off the reuseChessPrograms option. There are still some\r
-problems with reusing Crafty even in version 11.20.\r
-\r
-* Now the second chess program stays around by default too, if it ever\r
-gets started.\r
-\r
-3.5.1 -- Sat Apr 5 16:47:48 PST 1997 Tim Mann\r
-\r
-Beta test release.\r
-\r
-* Don't kill off and restart the chess program for each game; keep the\r
-same one running, using the "new" command to start a new game. This\r
-change works around the problem in Windows 95 that makes WinBoard crash it\r
-at times, and is generally desirable to make new games start faster. The\r
-second chess program (for TwoMachines) is still killed at the end of the\r
-game, and unfortunately this can still crash Windows 95. Temporarily\r
-added "white" to the initString to make this work with Crafty 11.20, which\r
-has a minor bug in "new". Older versions of Crafty have worse bugs in\r
-"new"; they should not be used with this version of xboard.\r
-\r
-* Support for FICS suicide chess: Parse illegal moves (that leave King in\r
-check) in game history. If CheckLegality is off, allow promotion to King\r
-and illegal moves in game files. We still generate e2e4 style notation\r
-for illegal moves.\r
-\r
-* Handle FICS "has timeseal; checking" message.\r
-\r
-* Changed the coords from white back to black; this was a bug.\r
-\r
-* Fixed problems compiling with K&R compilers.\r
-\r
-* Fixed an old bug in RegisterMove that was crashing cmail on some systems\r
-(notably linux).\r
-\r
-3.5.0 -- Thu Jan 2 16:59:49 PST 1997 Tim Mann\r
-\r
-Thanks to Frank McIngvale for much of the work on versions 3.4.4 and above!\r
-\r
-* Fix Crafty resumed game time bug (frankm)\r
-\r
-* Word wrap text in Analysis window (frankm)\r
-\r
-* More debug info for XPM loading (frankm)\r
-\r
-* Replaced config.sub, config.guess, etc., with up-to-date versions from\r
-autoconf 2.12. Hopefully this will fix problems on Pentium Pro machines.\r
-\r
-* Removed some Makefile gunk that was causing looping for one person.\r
-\r
-3.4.7 -- Thu Dec 19 14:22:41 PST 1996 Tim Mann\r
-\r
-All changes from Frank:\r
-\r
-* Retrieve ratings from ICC (and FICS, etc., when they add the Creating:\r
-message), save them in the PGN tags, and pass them to Crafty in Zippy mode.\r
-\r
-* Add settable time delay between characters in ICS login script.\r
-\r
-* Colorize messages like personal tells. Fix false recognition of channel\r
-tells.\r
-\r
-* Pass "tells" from Crafty through to ICS (in Zippy mode).\r
-\r
-* Implement ~/ filename convention from C shell for game and position file\r
-names.\r
-\r
-* ZIPPYACCEPTONLY feature for testing.\r
-\r
-3.4, patchlevel 6 -- Sat Nov 23 16:58:50 PST 1996 Tim Mann\r
-\r
-* Put recognition of "illegal move" messages from Crafty for\r
-illegal castling, etc., inside an #if that is currently turned off,\r
-because of a bug in Crafty that generates bogus "illegal move" messages\r
-after some moves that are actually legal and accepted by Crafty.\r
-\r
-* Added -checkLegality option; previously this could not be turned off.\r
-\r
-* Fixed an old bug in finding default board size parameters.\r
-\r
-* Differentiated among channel tell, kibitz/whisper, and personal tell/say.\r
-\r
-* Fixed a bug in detecting Xpm in the configure script.\r
-\r
-3.4, patchlevel 5 -- Mon Nov 18 16:22:53 PST 1996 Tim Mann\r
-\r
-* Added zic2xpm to the kit; it had been omitted by mistake.\r
-\r
-* Added some default colors for -colorize\r
-\r
-3.4, patchlevel 4 -- Sat Nov 16 18:10:17 PST 1996 Tim Mann\r
-\r
-This is meant to be a beta release in preparation for version 3.5.\r
-\r
-* Added InfoXBoard and ManXBoard to the Help menu.\r
-\r
-* Made Frank's ICS input box optional, defaulting to off.\r
-\r
-* Merged in Frank McIngvale's XbKit. Many new features, including\r
--clickClick mode, the Analysis modes, piece flashing, ZIICS import,\r
-ICS text colorization, and the ICS input box. Many thanks to Frank for\r
-supplying and documenting this code.\r
-\r
-3.4, patchlevel 3 -- Mon Nov 11 18:23:14 PST 1996 Tim Mann\r
-\r
-Small set of changes made while Frank McIngvale was working on XbKit in\r
-parallel. Unreleased in this form.\r
-\r
-* Updated zippy.README.\r
-\r
-* Removed useless X event handler and removed strange code for copying\r
-form translation table to board that worked around the bug it caused.\r
-This makes changing bindings in .Xdefaults more straightforward.\r
-\r
-* Now pressing the Control key steps back one move, and releasing it steps\r
-forward again.\r
-\r
-* Moved quit from "q" to "Q" for greater safety.\r
-\r
-* Use "unobserve" instead of "observe" to stop observing; needed on FICS.\r
-\r
-* Support for interface variable.\r
-\r
-* Strip titles from people who are talking to us, so (for example) Zippy\r
-won't try things like "tell Darooha(*) hello". Needed on FICS.\r
-\r
-3.4, patchlevel 2 -- Tue Jul 9 19:06:42 PDT 1996 Tim Mann\r
-\r
-This patchlevel is not planned to be an announced release. It's in\r
-preparation for integrating Frank McIngvale's XbKit. It mostly contains\r
-minor fixes I've accumulated since 3.4.pl1.\r
-\r
-* WinBoard /telnet option now fires up an external program, as\r
-with xboard, instead of trying to use a feature of NT 3.1 that does not\r
-exist in later versions of NT or in Windows 95. ChangeLog for 3.4.pl1\r
-said this had been implemented there, but it really wasn't.\r
-\r
-* Indicating player to move by the icon color now works under Windows 95.\r
-\r
-* WinBoard now kills the chess program when you exit using the system menu\r
-or the [X] button. Thanks to Michael Lowe.\r
-\r
-* Minor changes to Zippy, including: Now understands wild challenges on\r
-FICS; these used to crash it. Removed limit on how fast a game will be\r
-accepted. Use "set formula ..." on the chess server to limit this if you\r
-are using GNU Chess. Now sends correct opponent name to Crafty.\r
-\r
-* Added some missing default values to documentation. Thanks to Stuart\r
-Cracraft.\r
-\r
-* Bugfix: Trying to print "No fonts match pattern" error message would\r
-crash. This can happen to Linux users who don't install Helvetica, for\r
-example. \r
-\r
-* Bugfix: Defaulting feature in -size n,n,n,n,n,n would put us in an\r
-infinite loop.\r
-\r
-* Added more directories to search for Athena widgets on HPUX.\r
-\r
-* New cmail (3.12) from Evan Welsh; includes small fix from Kayvan Sylvan.\r
-\r
-* Recognize "illegal move" messages from Crafty for illegal castling, etc.\r
-\r
-* Bugfix: "name" command added to zippy.c for Crafty was producing error\r
-message if GNU Chess was in use.\r
-\r
-* In bughouse mode, suppress holding messages from console window; show\r
-holdings only in banner.\r
-\r
-* Minor fixes/cleanup to Makefile.in and configure.in.\r
-\r
-3.4, patchlevel 1 -- Mon Dec 11 13:43:12 PST 1995 Tim Mann\r
-\r
-* This patchlevel updates WinBoard to match xboard, and includes a few\r
-fixes and minor improvements. "-size tiny" and "-size n,n,n,n,n,n"\r
-are still not implemented for WinBoard.\r
-\r
-* Installed support for Crafty based on code from Bob Hyatt.\r
-Currently the only documentation for this is in the FAQ, and a few\r
-things don't work with Crafty 8.23. Please do not report these\r
-problems as bugs in either xboard or Crafty. Bob and I know about\r
-them. The worst ones (if not all of them) should be fixed in Crafty\r
-8.24.\r
-\r
-* Changed the kludge command we send when gnuchess wants to print\r
-something that doesn't end with a newline, from "help" to "bogus".\r
-This works because the error message gnuchess prints ends with a\r
-newline. It also improves compatibility with Crafty, which doesn't\r
-need the kludge, but for which sending "help" causes a problem.\r
-\r
-* Don't draw grid at all if lineGap is 0; previously we drew the grid\r
-with X "0-width" lines (usually 1 pixel wide) and then overwrote it.\r
-\r
-* Makefile: Removed xboard.info from "all" target so we won't try to\r
-rebuild it, because this fails on hosts that don't have makeinfo\r
-installed. Other minor fixes to "clean" targets, etc.\r
-\r
-* Fixes and cleanup to Auto Comment code that handles continuation\r
-lines and highlighting.\r
-\r
-* Auto Observe now tries to observe the game from the point of view of\r
-the player who was on your gnotify list. Requested by rng.\r
-Limitations: We can't tell which player it was unless you have ICS\r
-highlighting turned on. Also, currently "observe foo" works as\r
-required (observing from foo's point of view) only on ICC, but FICS\r
-will probably implement this soon.\r
-\r
-* "-size tiny" now makes the default font smaller automatically. This\r
-was implemented by introducing an extra Form widget in the hierarchy\r
-for all xboard windows, named either normalLayout, smallLayout, or\r
-tinyLayout. So you can have resource specifications that apply only\r
-to certain layouts; in particular, XBoard*tinyLayout*font.\r
-\r
-* Bug fix: EditGame or EditPosition while playing or examining still was\r
-not really being permitted.\r
-\r
-* WinBoard bug fix: On the EditPosition menu, King did not work.\r
-\r
-* Added text catalog of WinSock error messages to WinBoard, because\r
-Microsoft still has not put them in the system message catalog.\r
-\r
-* Removed support for older ICS game-ending messages that do not have\r
-a PGN result token (*, 0-1, 1-0, or 1/2-1/2) after the closing '}'.\r
-The code for older messages was sometimes firing on the newer\r
-messages, due to parsing ambiguity. If the current code sees an old\r
-message, it will understand that the game is over, but will always\r
-display * as a result token instead of trying to guess the result by\r
-interpreting the text message.\r
-\r
-3.4, patchlevel 0 -- Tue Nov 21 01:02:50 PST 1995 Tim Mann\r
-\r
-* This patchlevel was released for xboard only.\r
-\r
-* Updated the info file. It should now be as up-to-date as the man page,\r
-with good English except in the parts that pertain only to AmyBoard.\r
-\r
-* Added "-size tiny", requested by Bob Hyatt. Also cleaned up bitmap\r
-support and added "-size n,n,n,n,n,n" to allow arbitrary-sized bitmaps,\r
-if the actual bitmaps are supplied by the user.\r
-\r
-* Updated bughouse support.\r
-\r
-3.3, patchlevel 4 -- Sat Nov 18 02:27:21 PST 1995 Tim Mann\r
-\r
-* Unreleased beta that works with preliminary FICS bughouse code. Will\r
-need changes before release to track FICS message changes.\r
-\r
-* Removed use of .EX macro from man page. It is not supported by some\r
-nroff -man macro packages, notably the one on Slackware Linux. Switched\r
-to boldface for references to xboard and other commands within the man\r
-page, as this seems to be the modern way.\r
-\r
-* Bug fix: If ICS rejected a move, it was correctly undone on the board,\r
-but the message widget still displayed the bad move. Reported by DAV.\r
-\r
-* Normally, xboard in ICS mode fetches the move list whenever the board\r
-display switches to a new game. Doing this is now an option\r
-(getMoveList) that can be turned off, which is useful if you are watching\r
-multiple blitz games. Requested by rng.\r
-\r
-* Move list fetching code is now smarter: it ignores a move list if it is\r
-not for the right game.\r
-\r
-* Added support for bughouse as implemented on FICS. Holdings are shown\r
-in the window title in place of the strength numbers. A menu on mouse\r
-buttons 2 and 3 (same on both) lets you drop pieces. There is no checking\r
-as to whether you actually hold the piece you are trying to drop; we rely\r
-on ICS to check that. Notation of the form P@f7 is generated and parsed.\r
-The mate detector does not understand that non-contact mate is not really\r
-mate in bughouse, but this does no real harm. It results in a "#"\r
-suffix being displayed on the move notation, but xboard does not assume the\r
-game is over.\r
-\r
-* Bug fix: Promotion to a knight was not working with ICC! Thanks to\r
-Wendigo for the report.\r
-\r
-* Bug fix: Special pty code for host types *-*-aix3* and *-*-irix3*\r
-(supplied from configure.in) had a bug that would cause childio.c to\r
-fail to compile, due to a "continue" that was not within a loop.\r
-\r
-* Bug fix: In pgntags.c, memory was being freed while still in use. One\r
-symptom this caused was that on some machines, cmail would fail with a\r
-message that it could not find the BlackNA tag. The error was in some\r
-submitted code that I included in version 3.2.pl3 without reading\r
-carefully enough. Anders Forberg noticed the symptoms, and Evan Welsh\r
-(who had nothing to do with causing the bug) found the bug and submitted a\r
-fix; thanks to them both.\r
-\r
-* Removed restriction against using EditGame while playing, observing,\r
-or examining on ICS. You still get a warning popup.\r
-\r
-3.3, patchlevel 3 -- Sat Sep 16 11:44:05 PDT 1995 Tim Mann\r
-\r
-* Bug fix: Going directly from MachineWhite to TwoMachines mode would kill\r
-off the second chess program after Black's first move.\r
-\r
-* Added -timeIncrement feature. Thanks to Joel Rivat.\r
-\r
-* Deleted code that tries to keep you from observing more than one game,\r
-or observing while playing or examining. There is actually no problem in\r
-doing this, except that every time an update comes in from a different\r
-game than is currently being displayed, xboard fetches the history of the\r
-new game, which may be time-consuming if you are on a slow link.\r
-\r
-* Fixed configure so as not to crash when neither lex nor flex is found.\r
-lex or flex is needed only if the user wants to rebuild parser.c. Thanks\r
-to Phil Humpherys for reporting the crash.\r
-\r
-* Bug fix: config.h.in used #define instead of #undef for some macros used\r
-in the pty code in childio.c. This causes the code to fail to compile on\r
-some architectures, because the symbols are supposed to be undefined, not\r
-defined to empty, when they are not set in configure. Bug originated in\r
-3.3.pl0 when config.h was introduced. Thanks to Phil Humpherys for report.\r
-\r
-* Bug fix: ShowThinking would not show anything when current position had\r
-no move to display in the move window. E.g., if position was created by\r
-LoadPosition or EditPosition.\r
-\r
-3.3, patchlevel 2 -- Mon Aug 28 11:11:11 PDT 1995 Tim Mann\r
-\r
-* Zippy code was omitted from xboard-3.3.pl1 by mistake; now included.\r
-\r
-* For WinBoard, added hint to help file that you may need to turn off\r
-LocalLineEditing while typing dialing commands to your modem.\r
-\r
-3.3, patchlevel 1 -- Sat Aug 19 15:13:30 PDT 1995 Tim Mann\r
-\r
-* Zippy distribution is no longer separate from regular xboard distribution.\r
-\r
-* Deal properly with Show Thinking output from GNU Chess when it is\r
-thinking on its opponent's time. In TwoMachines mode this output is\r
-suppressed to avoid interfering with the output from the machine that is\r
-on move; in other modes it is displayed (including the move that GNU Chess\r
-is predicting the user will make next). GNU Chess produces this output\r
-only if it is built without -DQUIETBACKGROUND defined; this symbol is\r
-defined by default in patchlevels before pl75, but undefined by default in\r
-pl75.\r
-\r
-* Bug fix: Handling of initial board position in move list for wild games\r
-was broken, so wild games could not be observed and adjourned wild games\r
-could not be continued. Thanks to "Maximum Entropy" for the bug report.\r
-\r
-* Added feature: algebraic notation now shows "+" indicator for check\r
-and "#" for checkmate, as called for in PGN standard. Thanks to Kevin\r
-Maher for the suggestion.\r
-\r
-3.3, patchlevel 0 -- Thu Jul 27 22:21:07 PDT 1995 Tim Mann\r
-\r
-* Changed configuration to use a config.h file instead of passing zillions\r
-of -D options on the cc command line.\r
-\r
-* Merged a small fix and some updates to the texinfo file from Jochen\r
-Wiedmann. The texinfo file still needs work.\r
-\r
-3.2, patchlevel 5 -- Tue Jul 18 20:29:39 PDT 1995 Tim Mann\r
-\r
-* Beta test release of xboard only.\r
-\r
-* Updated WinBoard code to include new xboard features.\r
-\r
-* Added texinfo file from Jochen Wiedmann to the release, but not as the\r
-primary documentation. It needs updating, and the English needs work.\r
-I did make a few improvements, mostly to change incorrect uses of @var to\r
-either @samp or @code as appropriate.\r
-\r
-* Merged in code changes to 3.2.pl4beta from Jochen Wiedmann.\r
-\r
-* Fixed EditComment; did not pop up window in previous beta.\r
-\r
-* Added AutoComment feature.\r
-\r
-* Added GameListDestroy to disable the outdated game list popup in cases\r
-where we load a new game file without building a new popup.\r
-\r
-* Added yyskipmoves feature to parser.l to speed up building of gamelist.\r
-\r
-* gamelist.c wouldn't compile with a non-ANSI compiler. Fixed.\r
-\r
-* Change to yy_text handling in patchlevel 3 still had problems. Can't\r
-use AC_DECL_YYTEXT in configure.in, because that defines YYTEXT_POINTER\r
-according to whether the lexer on the current host makes yytext a pointer.\r
-But most people will be using a parser.c that was generated on another\r
-host and shipped with the package.\r
-\r
-3.2, patchlevel 4 -- Sun Jun 25 19:13:43 PDT 1995 Tim Mann\r
-\r
-* Beta test release of xboard only. \r
-\r
-* Added FIREWALLS section to man page.\r
-\r
-* Changed -icsport to be a string. Now with the -telnet option,\r
-specifying -icsport "" suppresses the second argument to telnet.\r
-\r
-* Added EditTags feature. Removed AboutGame from menu, because EditTags\r
-subsumes it. EditTags suggested by Jochen Wiedmann and first implemented by\r
-him in AmyBoard. xboard implementation is my own.\r
-\r
-* Fixed some missing or incorrect prototypes.\r
-\r
-3.2, patchlevel 3 -- Sat Jun 3 18:57:38 1995 Tim Mann \r
-\r
-* Beta test release of xboard only. \r
-\r
-* New version of cmail from Evan Welsh, to fix compatibility problems with\r
-perl 5.0.\r
-\r
-* Added game list feature on Load Game, based on code from Jochen\r
-Wiedmann. Integrated it with cmail.\r
-\r
-* Several bug fixes from Jochen Wiedmann, including one to my yy_text\r
-workaround for the difference in the type of yytext between lex and flex.\r
-\r
-* Handle clock pause on FICS.\r
-\r
-* Suppress clocks in untimed FICS games (time control 0 0).\r
-\r
-* Rebuilt configure script with autoconf 2.3. This fixes a bug in\r
-configuring for X11R6, where -lSM -lICE would not be added when needed.\r
-\r
-* Fixed inconsistent type declarations on IntSigHandler and\r
-CmailSigHandler. Bug report from Josh Daynard.\r
-\r
-* backend.c wouldn't compile with a non-ANSI compiler. Fixed.\r
-\r
-3.2, patchlevel 2 -- Tue Feb 7 14:50:30 1995 Tim Mann \r
-\r
-* Minor release of both xboard and WinBoard.\r
-\r
-* Added recognition of some FICS messages. On the other hand FICS is also\r
-changing some of its messages to match what xboard already recognizes.\r
-\r
-* Temporarily went back to using "promote" command on ICS instead of\r
-"a7a8=Q", because FICS doesn't implement the latter yet.\r
-\r
-* We now avoid using overlapped I/O on pipes in WinBoard, to make Windows\r
-95 beta 2 happy. This lets WinBoard work with GNU Chess on Windows 95!\r
-\r
-* Installed patches from Jochen Wiedmann to coordinate with Amiga XBoard.\r
-\r
-* Installed patch to cmail bug in LoadGame from Evan Welsh.\r
-\r
-* Bugfix: checkmate and stalemate moves entered with EditGame in ICS mode\r
-were not being handled correctly. Bug was in GameEnds().\r
-\r
-* Implemented EchoOn and EchoOff for xboard, using system("stty echo\n").\r
-Now passwords won't be echoed when you connect directly to ICS. Also,\r
-telnet negotiation characters aren't displayed (when possible).\r
-\r
-* Implemented more of the telnet protocol. Now connecting to a telnet\r
-server with "-icsport 23" should work even without giving the -telnet\r
-option. The telnet is in "old line-by-line mode".\r
-\r
-3.2, patchlevel 1 -- Sat Dec 10 13:50:46 1994 Tim Mann \r
-\r
-* This patchlevel released for WinBoard only.\r
-\r
-* winboard.c: Fixed ConsoleInputThread(). Needed to change CRLF to LF,\r
-not to CR. This was stopping normal /ics mode from working. Thanks to\r
-Asher Kobin for the bug report.\r
-\r
-* winboard.c: Fixed Raw(), EchoOn(), EchoOff(). Now they take effect\r
-immediately, not on the next console read after the one in progress.\r
-\r
-* winboard.c: Attempted to make WinBoard work with gnuchessx running\r
-directly on Windows (not remotely via rsh). It now works on NT, but only\r
-if gnuchess is told not to think on its opponent's time ("easy\n" removed\r
-from initString). The problem seems to be that GenerateConsoleCtrlEvent\r
-is not doing anything. On Windows 95 beta 2, we get error messages on\r
-both reading and writing to gnuchessx; I didn't investigate why.\r
-\r
-3.2, patchlevel 0 -- Wed Dec 7 13:23:36 1994 Tim Mann \r
-\r
-* Thanks to all the beta testers who gave me feedback: Josef Nelissen,\r
-Steve Booth, Evan Welsh, Dima Dakhnovsky, Chris Petroff, Peter Jansen,\r
-Derek Terveer, Michel van der List, Richard Lloyd, Shelly Mistry, and Mike\r
-Lee. Sorry if I forgot anyone. Thanks to Virendra Kumar Mehta for\r
-information about DYNIX/ptx.\r
-\r
-* Don't exit on keyboard EOF unless we get two in a row.\r
-\r
-* WinBoard only: added -localLineEdit switch to allow turning off local\r
-line editing if you really want to. It is still a bad idea to let the\r
-echoing be done remotely, however; see below.\r
-\r
-* Fixed some configure problems on HP-UX. [Steve Booth]\r
-\r
-* Fixed (I hope) configure problem on SunOS 5.3/Solaris 2.3. [Josef Nelissen]\r
-\r
-* cmail bugfix from Evan Welsh (cmail 3.4).\r
-\r
-3.1, patchlevel 9 -- Fri Dec 2 23:54:56 1994 Tim Mann \r
-\r
-* Beta distribution only\r
-\r
-* Always do local echo/edit of user typing in ICS mode. Doing the echo\r
-downstream may seem nicer in some modes, and it can be hard to turn that\r
-echo off, but the echoed characters can be interleaved with ICS output\r
-and make it impossible to parse correctly. For xboard this involved only\r
-a change to recommendations in the man page, as Raw() isn't implemented.\r
-For WinBoard, removing Raw() made a real difference. Added code in \r
-WinBoard to change /r/n back into /r on keyboard input, as we get the \r
-former when Raw() is not called.\r
-\r
-* Do not issue ICS "refresh" command after we start to observe a game\r
-unless we get to the next prompt without seeing a board image. Newest\r
-version of ICS doesn't require this refresh, but old versions around still\r
-do.\r
-\r
-* cmail bugfix and small code cleanup in LoadGame, from Evan Welsh.\r
-\r
-* Added keyboard accelerators N/P for LoadNextGame/LoadPreviousGame. Evan\r
-Welsh request.\r
-\r
-* Using "-" on the command line as a filename for loading (saving) games\r
-or positions specifies the standard input (standard output). Alain Picard\r
-suggestion.\r
-\r
-* On WinBoard only, a command line option without a leading '-' or '/' is\r
-now taken as the value of -lgf.\r
-\r
-* Changed to not use stdin, stdout, stderr as initializers in backend.c;\r
-needed for GNU libc compatibility. You also must build parser.c with flex\r
-(not lex) if you are using GNU libc, to avoid having the same problem\r
-there.\r
-\r
-* Changed WinBoard to avoid using "overlapped" input on the console. It\r
-now seems to fully work on Windows 95 beta 2.\r
-\r
-* Improved comment popups on WinBoard. Now newlines are handled properly,\r
-and the plain Comment popup window doesn't disappear and reappear when we\r
-step to a new move with a new comment.\r
-\r
-* Fixed bugs in detecting the absence of the time and otim commands.\r
-\r
-* Added built-in implementation of rcmd protocol to WinBoard. Windows NT\r
-does not implement passing signals through rsh, and Windows 95 does not\r
-have rsh at all.\r
-\r
-* Added -remoteUser option.\r
-\r
-3.1, patchlevel 8 -- Mon Nov 28 15:26:07 1994 Tim Mann \r
-\r
-* Beta distribution only\r
-\r
-* Rearranged ChangeLog file into reverse chronological order to be closer\r
-to GNU standards.\r
-\r
-* Integrated new cmail code from Evan Welsh (including cmail RCS rev 3.2).\r
-Includes a bug fix to TruncateGame.\r
-\r
-* Updated ICS address to be chess.lm.com.\r
-\r
-* Bug fixes to handling the aftermath of FatalError. Thanks to Chris\r
-Petroff for the bug report.\r
-\r
-* Test for remsh before rsh, other fixes for HP-UX. Thanks to Richard\r
-Lloyd. I wasn't able to do all the things he suggested, so there may\r
-still be some rough edges in building on HP-UX. See the FAQ file for hints.\r
-\r
-* Bug fix; added missing check for HAVE_SYS_SYSTEMINFO. Thanks to Josef\r
-Nelissen for testing on Solaris 2.x.\r
-\r
-* Updated WinBoard to match xboard. (WinBoard still has a few option\r
-dialogs that don't exist in xboard.)\r
-\r
-* Changed Hint output to a popup.\r
-\r
-* ShowThinking output and move output no longer overwrite each other.\r
-ShowThinking output won't appear if the displayed position is not current. \r
-ShowThinking output in TwoMachines mode made clearer and documented.\r
-\r
-* Implemented --enable-ptys and --disable-ptys arguments to configure.\r
-\r
-* Fixed Book and Hint code to work over a pty with echo enabled and tabs\r
-expanded to spaces. Thanks to Dima Dahknovsky for the bug report.\r
-\r
-* Moved Attention calls from all over xboard to one place, inside\r
-SendToProgram.\r
-\r
-* Added bulletproofing to ShowThinkingEvent.\r
-\r
-* Added code to handle "refresh N" boards that come in from ICS properly,\r
-assuming ICS is changed to mark them with a new relation code (-3).\r
-\r
-3.1, patchlevel 7 -- Sun Nov 13 22:16:01 PST 1994 -- Tim Mann\r
-\r
-* Beta distribution only\r
-\r
-* Changed ShowThinking to just show the current best line in the\r
-DisplayMessage area, instead of dumping everything to stdout.\r
-\r
-* Installed new cmail (RCS rev 3.1) and cmail.man (RCS rev 1.10), and\r
-changes to cmail code in backend.c, from Evan Welsh.\r
-\r
-* Miscellaneous minor fixes.\r
-\r
-3.1, patchlevel 6 -- Fri Nov 4 12:53:53 PST 1994 -- Tim Mann\r
-\r
-* This patchlevel was not actually released to anyone.\r
-\r
-* Updated the pty code to be based on GNU Emacs 19.24, and moved it to a\r
-separate file. It was hard to split out just the pty configuration from\r
-all the stuff emacs does with its custom configure script and .h files,\r
-but I did my best.\r
-\r
-* Converted from imake to GNU autoconf. This was a serious upheaval. \r
-\r
-* Put in code to help trap "error gathering move list" problem reported by\r
-Michel van der List if it recurs. I couldn't reproduce it.\r
-\r
-3.1, patchlevel 5 -- Mon Oct 31 21:12:00 PST 1994 -- Tim Mann\r
-\r
-* Beta distribution only.\r
-\r
-* We now test for checkmate or stalemate in EditGame mode after every user\r
-move, and in LoadGame mode whenever we hit the end of a game without\r
-seeing a PGN end marker. cmail needs an update to deal with this\r
-correctly; Evan promises one.\r
-\r
-* Bugfixes in new move generator. Thanks to Mike Lee for reporting one of\r
-the bugs.\r
-\r
-* Imakefile was omitted from patchlevel 4.\r
-\r
-3.1, patchlevel 4 -- Mon Sep 19 18:19:46 PDT 1994 -- Tim Mann\r
-\r
-* Beta distribution only.\r
-\r
-* The move generator includes a mate tester. Initially this is used only\r
-by cmail, and even that usage needs further work.\r
-\r
-* Wrote a true move generator and used it to replace all the move\r
-disambiguation and legality checking code in parser.l. The move generator\r
-is capable of dealing correctly with en passant and castling availability,\r
-but the rest of the program still does not keep track of this information.\r
-\r
-* Bug fix: xboard did not handle "foo has made you an examiner of game 23"\r
-message. Thus you could not use examine features until the next board\r
-came in, showing your new relation to the game. Thanks to POOKIEWOOKIE on ICS\r
-for the bug report.\r
-\r
-* Added AutoObserve feature. Thanks to Chris Petroff for the idea.\r
-\r
-* Added Book feature to use new gnuchess "bk" command. Mike McGann request.\r
-\r
-* Redid code to handle missing "time" command in gnuchess, because latest\r
-gnuchess no longer sends a response to this command. \r
-\r
-* Eliminated need for -DFLEX. Thanks to Michael Shields (Vladimir?) for\r
-the idea.\r
-\r
-* Added missing code to implement MoveNow in TwoMachines mode.\r
-\r
-* Added ShowThinking feature. Thanks to Richard Lloyd for the idea.\r
-\r
-* Applied patches from Evan Welsh; some fixes and improvements to the\r
-cmail code.\r
-\r
-* Fixed bug in moving from EndOfGame mode to MachineWhite or MachineBlack,\r
-introduced in previous patchlevel. Also fixed related bug in ending a\r
-game in ICS mode; was entering EndOfGame mode instead of IcsIdle.\r
-\r
-* Added patch to implement internetChessServerLogonScript flag, from Kevin\r
-O'Connor. Thanks!\r
-\r
-3.1, patchlevel 3 -- Wed Sep 7 13:22:07 PDT 1994 -- Tim Mann\r
-\r
-* Beta distribution only.\r
-\r
-* Merged in new cmail code from Evan Welsh. He added the ability to have\r
-more than one game per message, needed for official IECG matches. I added\r
-the ability to resign or offer/accept/decline a draw in a cmail game.\r
-\r
-* Bugfix: invalid -tc option caused segmentation fault; DisplayFatalError\r
-was called too early in initialization. Georges Honore reported this bug.\r
-\r
-* Decided to keep EndOfGame mode as an element of the user interface---it\r
-means that a gnuchess game or loaded game has ended, and the user must\r
-explicitly select EditGame to edit it, rather than just being able to\r
-enter more moves freely. But internally there is no longer an invariant\r
-tying this mode to whether the chess program is running.\r
-\r
-* Zippy bugfix: Was saving only the final position in the -sgf file when\r
-the game ended by something other than resignation or flag. Also fixed\r
-the longstanding bug that Zippy would think the final board of such a game\r
-was a new game and restart the chess program.\r
-\r
-* Now does a better job of faking castling availability in FEN. We still\r
-don't really keep track of it, but now at least we don't say that castling\r
-is still available when the king or rook is not on its home square.\r
-\r
-* Bugfix: Initial board of game history for wild games was going through\r
-too much processing, causing us to forget the game length, which is now\r
-needed by ParseGameHistory. This was causing problems with resuming\r
-adjourned wild games.\r
-\r
-* Updated ICS host to ics.onenet.net.\r
-\r
-* Zippy now accepts challenges where the opponent specified his color.\r
-\r
-* Added ZIPPYPASSWORD2 to let operator give commands directly to gnuchess.\r
-\r
-* Bitmap directory can include alternative icons now, too.\r
-\r
-* Handle "Game * (*) has no examiners" message from ICS.\r
-\r
-* Revamped window title and icon name selection.\r
-\r
-3.1, patchlevel 2 -- Sun Jun 12 17:16:28 PDT 1994 -- Tim Mann\r
-\r
-* "Beta" distribution for Zippy users only.\r
-\r
-* Bugfix: common.h was assuming that X11 type Boolean is char, which is\r
-not always true. This might have caused all sorts of obscure bugs!\r
-\r
-* Installed new bitmaps from Elmar Bartel as the default. Many thanks!\r
-The old bitmaps can be used by changing the "bitmaps" symbolic link before\r
-compiling xboard, or by using the -bitmapDirectory option at runtime.\r
-\r
-* Loading a game that ends with the PGN unfinished symbol ("*") now always\r
-leaves you in EditGame mode.\r
-\r
-* Added documentation of -icscomm to man page. Thanks to Maarten Remkes\r
-for the linux script.\r
-\r
-* ^C now kills gnuchess as well as xboard. Thanks to Dima Dakhnovsky for\r
-reminding me how to do this.\r
-\r
-* Bitmap icon color now indicates player to move. Stuart Cracraft\r
-suggestion.\r
-\r
-* Changed piece bitmap flags to have just one flag, which points to a\r
-directory full of bitmaps, instead of a flag for each bitmap. Also\r
-changed bitmap naming convention.\r
-\r
-* "Connection closed by ICS" is no longer a FatalError popup. This was\r
-too annoying in the normal case where the user typed "quit".\r
-\r
-* Changed default font to 14 pixels instead of 10 points. This seems to\r
-make it close to the size I want it to be on more displays.\r
-\r
-* Major mode (GNU Chess, etc.) appears in title bar. Stuart Cracraft\r
-request.\r
-\r
-* Bug fix: EditGameEvent, MachineBlackEvent, MachineWhiteEvent, and\r
-TwoMachinesEvent were calling PauseEvent to get out of pause mode, which\r
-now has undesired side effects, such as advancing the display to the\r
-forwardMostMove. It works fine to just set pausing = FALSE instead.\r
-\r
-* IcsExamining mode now lets you access ICS edit position commands using\r
-the same popup menus as xboard's EditPosition mode. Thanks to DAV on ICS\r
-for inspiring the idea.\r
-\r
-* Corrected test for gcc on HP in Imakefile; thanks to Richard Lloyd.\r
-\r
-3.1, patchlevel 1 -- Wed Jun 1 16:25:11 PDT 1994 -- Tim Mann\r
-\r
-* Added parser.c.lex and parser.c.flex to the distribution.\r
-\r
-* Added HP gcc options to Imakefile, from Mats Nylen.\r
-\r
-* EndOfGame mode no longer highlights EditGame mode indicator, because the\r
-modes really do differ. I would like to get rid of EndOfGame mode in the\r
-future, at least as far as users can see.\r
-\r
-* Larger %a in parser.l, needed for RS/6000 users.\r
-\r
-* Minor improvements to Mail Move error messages.\r
-\r
-* When -debug flag is given to xboard, -v is passed to cmail.\r
-\r
-* Old Save Style uses "1. ..." instead of "1..." when black moves after a\r
-comment; more like xboard 3.0's actual style.\r
-\r
-* New version of cmail from Evan Welsh. Looks for UCB Mail in a more\r
-portable way and has some minor bug fixes.\r
-\r
-* Bug fix: Saving a FEN position while in EditPosition mode with black to\r
-play was showing white to play in the saved position.\r
-\r
-3.1, patchlevel 0 -- Fri May 20 16:36:15 PDT 1994 -- Tim Mann\r
-\r
-* This is the first general release since 3.0, patchlevel 9. Releases\r
-since then have been limited-distribution or beta releases.\r
-\r
-* Thanks to my version 3.1 beta testers: Dmitry Dakhnovsky, Ed Hanway,\r
-Richard Lloyd, Mike McGann, Shelly Mistry, Josef Nelissen, Chris Petroff,\r
-Jack Robertson, Michel van der List, Ky Macpherson, Derek Terveer, and\r
-Evan Welsh. Sorry if I've forgotten anyone who gave me feedback.\r
-\r
-* Updated man page.\r
-\r
-* Minor cleanup on menu sensitivity code.\r
-\r
-* Integrated another even better version of cmail from Evan Welsh,\r
-including some code he supplied in xboard itself.\r
-\r
-* A few more fixes to cmail support.\r
-\r
-* Automatically update clocks after an ICS "moretime" command.\r
-\r
-* Handle ICS automatic examine mode (set examine 1) after a game.\r
-\r
-3.0, patchlevel 14 -- Tue May 17 13:41:44 PDT 1994 -- Tim Mann\r
-\r
-* Beta test release only.\r
-\r
-* Don't suppress prompt on first board of game being examined; otherwise\r
-it looks like nothing happened at all (i.e., like you're lagged).\r
-\r
-* Added StopExamining and StopObserving (Chris Petroff suggestion).\r
-\r
-* Made Reset do a refresh on ICS. John Chanak's original ICS code for\r
-xboard tried to do this; I finally decided it was a good idea after all.\r
-\r
-* Fixed bugs in handling updates that come in while you are pausing in\r
-examine mode. This is pretty tricky to do right.\r
-\r
-* Made un-Pausing immediately pop you to the current position. This is\r
-always necessary in examine mode, since the game may have changed under\r
-you; your remembered moves might no longer be right. So I made it do the\r
-same in all modes.\r
-\r
-* Took Detach Examine mode back out...used Pause mode for this instead!\r
-\r
-* Put in a trap for the GNU Chess bug of printing an Illegal Move message\r
-when its own hint move is illegal.\r
-\r
-* Attempted to fix a Zippy bug; bogus "exited unexpectedly" messages after\r
-it checkmates its opponent. This involved adding an argument to GameEnds\r
-to say who says it ended (ICS, GNU, etc.) and taking different actions in\r
-different cases. Unfortunately, this just restored an older Zippy bug, where\r
-Zippy restarts gnuchess when it gets the board with the final position,\r
-because GameEnds still puts xboard in EndOfGame mode. Sigh.\r
-\r
-* We now capture elapsed time on last move when getting game history.\r
-(Josef Nelissen bug report)\r
-\r
-* Rewrote code to redisplay last file title so it really works.\r
-\r
-* Fixed bug in oldSaveStyle.\r
-\r
-* Larger %a and %o were needed for lex.\r
-\r
-3.0, patchlevel 13 -- Mon May 16 16:26:22 PDT 1994 -- Tim Mann\r
-\r
-* Beta test release only.\r
-\r
-* FatalError popups stay on the screen now. If the error is really fatal,\r
-all functions are disabled, and the program exits when you press OK.\r
-\r
-* Redisplay last file title when using Load (Next/Previous/Same) Game.\r
-\r
-* Zippy understands new match challenge message format on ICS.\r
-\r
-* Added Revert command.\r
-\r
-* When examining a game on ICS, < > buttons do ICS backward/forward\r
-commands, unless you set the Detach Examine option. Thanks to Dima\r
-Dakhnovsky for the idea.\r
-\r
-* Fixed various minor problems in cmail mode.\r
-\r
-* cmail generates the tags now. New version of cmail from Evan Welsh.\r
-\r
-* cmail mode won't let you do MailMove unless the currently displayed\r
-position is exactly one move past the end of the game you loaded.\r
-\r
-* Fixed building of man pages in Imakefile\r
-\r
-* Updates to INSTALL file\r
-\r
-3.0, patchlevel 12 -- Sat May 7 21:10:03 PDT 1994 -- Tim Mann \r
-\r
-* Beta test release only.\r
-\r
-* Brought man page up to date.\r
-\r
-* Added Shift+R to resign from keyboard.\r
-\r
-* Some items on Action menu available in GNU Chess mode now.\r
-\r
-* Revamped Action menu.\r
-\r
-* Reordered functions in backend.c as a small step toward reorganizing\r
-this whole mess.\r
-\r
-* Generate TimeControl PGN tag.\r
-\r
-* Get type of ICS game (e.g., rated blitz) and save in PGN tags.\r
-\r
-* Bug fix: Clocks were not redisplayed when entering EditGame mode.\r
-\r
-* Bug fix: Clocks were not being redisplayed after loading a game file\r
-with -td 0, so they could show the wrong color active.\r
-\r
-* Bug fix: Chess programs would be killed and match mode would exit\r
-prematurely when loading a PGN game fragment ending with "*".\r
-\r
-* ICS command "sposition" no longer confuses xboard.\r
-\r
-* Integrated new version of cmail (with support code in xboard) from Evan\r
-Welsh.\r
-\r
-* Added TruncateGame, MoveNow, RetractMove, and QuietPlay.\r
-\r
-* Bug fix: switching between MachineWhite and MachineBlack was not calling\r
-Attention(). Reported by Dino Dini.\r
-\r
-* More improvements to INSTALL and Imakefile.\r
-\r
-* Pack moves into 79 character lines in PGN output. We don't generate\r
-check indications, and we always break the line before the result,\r
-so this is not quite PGN export format.\r
-\r
-* Use FEN tag in PGN.\r
-\r
-* Improved finding and counting of game starts in save files.\r
-\r
-* Negative position or game numbers in -lpi/-lgi mean to seek to that byte\r
-offset. Hook for possible future features, not in man page.\r
-\r
-* Detect and handle absence of either "time" or "otim" commands in\r
-gnuchess.\r
-\r
-* Don't use "promote" command to ICS anymore.\r
-\r
-* Handle switching sides and taking back moves on FICS.\r
-\r
-* Handle flip state flag in style 12 board.\r
-\r
-* Handle examine mode on ICS.\r
-\r
-* Improved error popups for various kinds of illegal moves.\r
-\r
-* Suppress unasked-for hints from gnuchess (which it generates in post\r
-mode).\r
-\r
-* Load/save position functions use FEN. Old style also supported.\r
-\r
-* Added detailed error messages if loading a bitmap file fails.\r
-\r
-* Small board has 2-pixel lines between squares instead of 3-pixel.\r
-\r
-* Added OldSaveStyle and AboutGame.\r
-\r
-* Renamed ForceMoves to EditGame.\r
-\r
-3.0, patchlevel 11 -- Tue Sep 21 15:25:36 PDT 1993 -- Tim Mann \r
-\r
-* The following changes were present in xboard 3.0, patchlevel 11, but the\r
-first group did not make it into WinBoard 3.0 until later. xboard\r
-3.0.pl11 was a limited-distribution release only, mostly to Zippy users.\r
-\r
-* Man page minor fixes.\r
-\r
-* Added a missing file close.\r
-\r
-* Removed automatic error popdown on Reset, which was destroying some\r
-error messages before they could be read.\r
-\r
-* Fixed char vs. unsigned char warnings on bitmaps.\r
-\r
-* Use ICS board style 12. Some improvements to ICS parsing.\r
-\r
-* Comment window is now labelled with the move the comment is on, and\r
-comments don't pop down when you step to the next move.\r
-\r
-* Save files now in PGN format.\r
-\r
-* Support for loading PGN files. PGN tags pop up when a PGN game file\r
-is loaded.\r
-\r
-* More info in INSTALL and Imakefile about building for Suns (and\r
-other systems).\r
-\r
-* WinBoard 3.0 patchlevel 11 split off from an early version of xboard\r
-3.0 patchlevel 11, so it does not have all the features of that\r
-patchlevel. The following changes made it into both xboard and\r
-WinBoard:\r
-\r
-* Made Comment dialog non-modal in WinBoard.\r
-\r
-* EndOfGame mode is now more transparent. It looks like ForceMoves\r
-mode except that there is no chess program running.\r
-\r
-* Small bug fixes in clock management. Most noticeably, pausing when\r
-it is gnuchess's move now works as documented (again).\r
-\r
-* Add minimal support for -icscomm option. Not documented yet because\r
-I haven't sorted out the issues with setting the tty modes on the comm\r
-port device, or with locking it properly. But it's usable by wizards.\r
-\r
-* Don't restart the chess program upon Backward event from EndOfGame mode.\r
-\r
-* Suppress extra prompt after ICS sends us a board.\r
-\r
-3.0, patchlevel 10 -- Sat Sep 11 18:44:03 PDT 1993 -- Tim Mann \r
-\r
-* Beta test release only.\r
-\r
-* Zippy now plays chess. zippy.c and zippy.h are still not included\r
-in the standard distribution, but are available on request.\r
-\r
-* Switched to using style 12 on ICS.\r
-\r
-* Updated man page, and documented use of XBoard*form.translations to\r
-add more shortcut keys.\r
-\r
-* Added shortcut keys "d" to claim/offer/accept a draw, and "t" to\r
-call flag. Suggested by venu on ICS.\r
-\r
-* More explicit instructions in INSTALL file.\r
-\r
-3.0, patchlevel 9 -- Tue Sep 7 14:02:00 PDT 1993 -- Tim Mann\r
-\r
-* General release, minor update to 3.0.pl8.\r
-\r
-* Loosened checking on whether it's okay to start a move, to satisfy\r
-ICS ultra-blitz players. Now we don't check whether it's your turn\r
-until you let go of the piece.\r
-\r
-* Parser now recognizes "+-+" as meaning the game ended in a draw.\r
-\r
-* Got rid of S_NONE symbol, which seems to conflict with some symbol\r
-Sun defines.\r
-\r
-* Tweaked the man page. Clarified that there is currently no way for\r
-two people running copies of xboard to play each other without going\r
-through the Internet Chess Server.\r
-\r
-* Fixed a bug in color name conversion. Asking for two different\r
-colors whose names were the same in the first four characters would\r
-get you two copies of the first one. Thanks to Volker Zink for the\r
-bug report.\r
-\r
-* Improved confusing Usage() message.\r
-\r
-* Added a bunch of Sun information to the Imakefile and INSTALL file.\r
-Thanks to Ed Hanway, Arik Klingensmith, and others who responded.\r
-\r
-* Test for defined(WIN32) instead of !defined(unix).\r
-\r
-* Avoid using (void *) type with non-ANSI C compilers. Thanks to\r
-James Altucher for the bug report.\r
-\r
-3.0, patchlevel 8 -- Thu Sep 2 12:23:01 PDT 1993 -- Tim Mann\r
-\r
-* Note: Patchlevel 8 was the first non-beta release of xboard 3.0\r
-\r
-* Added cmail to distribution. Contributed (and still maintained) by\r
-Evan Welsh.\r
-\r
-* Bug fix: -queen option wasn't initializing menu check. Reported by\r
-Pat Surry.\r
-\r
-3.0, patchlevel 7 -- Thu Aug 26 13:23:24 PDT 1993 -- Tim Mann\r
-\r
-* Sent WinBoard 3.0.pl7 to Torre on ICS\r
-\r
-* Added parser.h to hold the interface to parser.l\r
-\r
-* Upgraded COPYING file and copyright notices to GNU GPL version 2.\r
-\r
-3.0, patchlevel 6 -- Tue Aug 24 15:16:13 PDT 1993 -- Tim Mann\r
-\r
-* We no longer display intermediate positions or intermediate comments\r
-while loading a game file with -timeDelay 0 or loading an opening to\r
-start up a -matchMode game.\r
-\r
-* Loading an empty game from an xboard save file now gives a status\r
-message "No moves in game" instead of an error popup saying "Game not\r
-found in file."\r
-\r
-* Added comment.awk to distribution.\r
-\r
-3.0, patchlevel 5 -- Tue Aug 17 16:45:54 PDT 1993 -- Tim Mann\r
-\r
-* Bug fix: xboard would crash if it couldn't get all its colors; now\r
-it switches to monoMode instead. Also, xboard was trying to convert\r
-color resources even when using a b/w display. Reported by Larry\r
-Rogers.\r
-\r
-* Bug fix: Declared fields of TimeMark as signed so that we get signed\r
-instead of unsigned arithmetic. SubtractTimeMarks was breaking on\r
-Alpha AXP (which has 64-bit longs) with old declarations. Reported by\r
-Michel van der List.\r
-\r
-* Bug fixes: Keyboard accelerators now work after EditComment window is\r
-popped down. Iconize keyboard accelerator now works even if xboard\r
-was started with -iconic flag and later deiconized.\r
-\r
-* Bug fix: The routine that tests whether a move is illegal because it\r
-would leave you in check was not handling e.p. captures properly.\r
-Reported by Patrick Surry.\r
-\r
-* Bug (?) fix: Was adding time to clocks at time control even when\r
-loading a game file. Actually it's not entirely clear how time\r
-controls should be dealt with when some moves are loaded from a file\r
-or clicked in with ForceMoves. For now ForceMoves mode does add the\r
-time (because it can be used to change moves during a live game), but\r
-LoadGame mode does not.\r
-\r
-* Updated usage message.\r
-\r
-* Previous attempted fix to matchMode had broken TwoMachines mode and\r
-generally needed more work. Also simplified command line interface to\r
-matchMode.\r
-\r
-3.0, patchlevel 4 -- Thu Aug 5 14:17:18 PDT 1993 -- Tim Mann\r
-\r
-* Thanks again to the beta testers listed for 3.0 patchlevel 3, and also\r
-Desnogues, Steve Cariglia, Niklas Engsner, Mark Silver, and Roger Rowe.\r
-\r
-* Reorganized man page, splitting OPTIONS into subsections.\r
-\r
-* matchMode was very broken; fixed.\r
-\r
-* Changed convention for turning off command line options from --opt\r
-to -xopt, to be less inconsistent with GNU standards. Also changed\r
-the long command line options to take True/False arguments like\r
-resources; seems to make more sense this way.\r
-\r
-* Added AlwaysQueen option -- suppresses promotion dialog and always\r
-promotes to a queen if you move a pawn to the last rank. Has no\r
-effect on gnuchess (or your ICS opponents!) -- they can still\r
-underpromote.\r
-\r
-* Subtracted an extra fudge term when determining how wide message and\r
-title widgets should be. This fixes a problem some beta testers had.\r
-Wish I knew why it's needed.\r
-\r
-* Bugfix in parser; symptom was that you couldn't do LoadGame after\r
-observing a game on ICS.\r
-\r
-* Bugfix in Forward; didn't work after game ended while Pause was turned on.\r
-\r
-* Removed bogus execute bits on .h files.\r
-\r
-* Use REMOTE_SHELL and TELNET_PROGRAM definitions.\r
-\r
-* MachineWhite and MachineBlack now work from TwoMachines mode.\r
-\r
-* Popping down an error message with the [ok] button was not turning off\r
-the errorUp flag, so the next move would cause xboard to try to pop it\r
-down again, resulting in a wild memory reference and sometimes a crash.\r
-\r
-3.0, patchlevel 3 -- Tue Aug 3 17:40:27 1993 -- Tim Mann\r
-\r
-* Thanks to my beta testers: Patrick Surry, Takuya Kojima, Robert J. Luoma,\r
-Chris L. Petroff, Richard K. Lloyd, Michel van der List, Craig Metz,\r
-Antoon Frehe, Simon Clift, Shelly, Eric Peterson, Christopher Mitchell,\r
-Martin Koch, Ed Hanway, Steve Booth, Udo, Ken Hobday, and Joseph Duhamel.\r
-\r
-* Improved error messages for trying to move the wrong color pieces or\r
-to move when it's not your turn.\r
-\r
-* Special code for monoMode on 1-bit displays now understands displays\r
-where 1=white and 0=black.\r
-\r
-* Declare getenv() if <stdlib.h> not included; avoids a compiler warning.\r
-\r
-* Documented borderXoffset and borderYoffset.\r
-\r
-* Added -titleInWindow option for use with X window managers that\r
-don't let us set the title in the window banner.\r
-\r
-* Fixed error message printing in WinBoard; system error messages no\r
-longer appear as numeric codes.\r
-\r
-* The error message popup is now non-modal; you don't have to press the\r
-[ok] button before you can do something else. In addition, the popup is\r
-positioned so that it doesn't cover up the board (too much), and making a\r
-move or otherwise clicking on the board pops it down. (Not implemented in\r
-WinBoard.)\r
-\r
-* You can now call your opponent's flag in ICS mode by clicking on his\r
-clock. \r
-\r
-* Fixed minor bugs in -flipView option and documented exactly how xboard\r
-decides which way to flip the view.\r
-\r
-3.0, patchlevel 2 -- Fri Jul 30 22:20:23 PDT 1993 -- Tim Mann\r
-\r
-* Added Autosave to Options menu. Would be better to have Save\r
-Options dialog as in WinBoard, but this was quick to do and gives the\r
-most-needed functionality.\r
-\r
-* Changed "Reload Game" on menu to "Reload Same Game".\r
-\r
-3.0, patchlevel 1 -- Thu Jul 8 21:22:59 PDT 1993 -- Tim Mann\r
-\r
-* Sent a copy of patchlevel 1 to Patrick Surry to beta-test.\r
-\r
-* Added -cmail option that sets appData.cmailMode. Currently a no-op.\r
-In the future this may set special modes for use by the cmail script\r
-for playing chess by email.\r
-\r
-* Added LoadNextGame, LoadPreviousGame, and ReloadGame to File menu.\r
-ReloadGame suggested by Patrick Surry.\r
-\r
-* Added -flipView command-line option. Suggested by Patrick Surry.\r
-\r
-* Fixed bugs in parser.l: (1) Pattern for "# xboard game file ..."\r
-needed to match to end of line. (2) Start of a new file was not matching\r
-the ^ start-of-line character. The fix for this is a kludge.\r
-\r
-* Made game counting code in LoadGame more robust, and made LoadGame\r
-able to detect the end of a saved partial game (by noticing the start\r
-of the next game) in game files created by XBoard itself. We don't\r
-try to find the start of the next game that way in other kinds of game\r
-files, because the only way I can think of to do that is to look for\r
-another move #1, and that technique gets too many false hits.\r
-\r
-* Fixed recently introduced bug in LoadGame when game starts with a\r
-position diagram.\r
-\r
-3.0, patchlevel 0 -- Fri Jun 25 14:17:17 PDT 1993 -- Tim Mann\r
-\r
-* Changes in this patchlevel were too numerous to list. Larger ones are\r
-listed below.\r
-\r
-* Added a popup dialog to enter and edit comments. Inspired by some\r
-code from Patrick Surry. Changed the normal read-only comment popup\r
-to the same style.\r
-\r
-* Added ICS init script feature from Karl Schwamb.\r
-\r
-* Added some ESIX fixes and OMIT_SOCKETS ifdef option, from Kayvan Sylvan.\r
-\r
-* Revamped code to allow use of flex instead of lex on parser.l.\r
-Using flex requires adding -DFLEX to defines in Imakefile.\r
-\r
-* Source code is split into front end (xboard.c), which knows about X\r
-and Unix, and back end (backend.c), which knows about chess, gnuchess,\r
-and the ICS. There is also a front end for Windows NT.\r
-\r
-* Boolean command line options now use "-foo" to turn on and "--foo"\r
-to turn off instead of "-foo true" and "-foo false". [Later -xfoo;\r
-see above.] \r
-\r
-* Added menu commands to control autoflag, bell, and coords options.\r
-\r
-* User interface has a new look: (1) Menu bar instead of array of\r
-buttons. A few very commonly used features have small buttons in\r
-addition to being on the menus. (2) Large font for clock. (3) Pop-up\r
-dialogs for errors.\r
-\r
-2.1, patchlevel 11 -- Sat Jun 5 00:01:01 PDT 1993 -- mann@src.dec.com\r
-\r
-* Added code to deal with "wild" games on ICS. This includes allowing\r
-castling with the king on d1 or d8, which is allowed in wild(1) games\r
-if the king started there. Notation is o-o to castle "short"---to\r
-whichever side the king is closer to---and o-o-o to castle "long."\r
-Right now wild castling is always allowed by xboard; we rely on ICS or\r
-gnuchess to reject it when we aren't really in wild mode.\r
-\r
-* memcpy call had arguments in wrong order.\r
-\r
-* Removed April Fool code\r
-\r
-2.1, patchlevel 10 -- Mon Feb 15 10:19:31 PST 1993 -- mann@src.dec.com\r
-\r
-* Avoid trying to select on a pipe when using System V. Needed to\r
-copy some code from InitChessProgram() up into establish().\r
-\r
-* Bug fix in disambiguating pawn moves like "ed".\r
-\r
-* Fix to error handling in ReceiveFromProgram.\r
-\r
-* Bug fix: entering EditPosition mode with black to play highlighted\r
-White's clock instead of Black's.\r
-\r
-* Added telnetProgram resource in case "telnet" is not the name of the\r
-telnet program.\r
-\r
-2.1, patchlevel 9 -- Fri Jan 22 19:08:27 PST 1993 -- mann@src.dec.com\r
-\r
-* Entering Force Moves mode clears "flag has fallen" messages from display.\r
-\r
-* ICS host name can now be in numeric format; for example 128.2.232.4.\r
-\r
-* Bug fix: LegalityTest was failing to test whether a pawn move was\r
-illegal because the move would discover a check.\r
-\r
-* Handle ICS message "mann asserts a win over manntest, who disconnected."\r
-\r
-* Bug fix: A recent change to PromotionCallBack had broken\r
-underpromotion to a knight.\r
-\r
-* Bug fix: In EditPosition mode, dragging a piece onto a square border\r
-would make it vanish. xboard wasn't distinguishing this case from\r
-dragging the piece off the board. Thanks to Matthew Kidd.\r
-\r
-* Removed "static" declaration from yywrap for compatibility with IRIX\r
-version of lex. Thanks to stiller@blaze.cs.jhu.edu.\r
-\r
-* Added substitutes for bzero, bcopy, and gethostname for Solaris\r
-SVR4. Thanks to Michael Grant.\r
-\r
-* Bug fixes to queen move disambiguation. Bugs showed up only when\r
-promotion resulted in more than one queen on the board.\r
-\r
-2.1, patchlevel 8 -- Fri Dec 11 17:54:18 PST 1992 -- mann@src.dec.com\r
-\r
-* parser bug fix: It now really works to leave off the piece a pawn is\r
-promoting to and let it default to queen.\r
-\r
-* When starting to observe or play an ICS game, don't draw board in\r
-initial position and then immediately redraw it in the current\r
-position.\r
-\r
-* Handle ICS messages when an "abuser" forfeits a game by\r
-disconnecting and when a game is aborted ("removed") by an\r
-administrator.\r
-\r
-* Bug fix: A user move when in LoadGame+Pause mode was resuming the\r
-game load instead of putting us in force mode.\r
-\r
-* It seems that crashes inside sscanf when xboard is compiled with gcc\r
-(as on IBM PS/2 AIX, mentioned below, and also on VAX Ultrix 3.1) are\r
-caused by an incompatibility between gcc and the sscanf implementation\r
-on these platforms. A workaround is to specify -fwritable-strings to\r
-gcc (see the gcc documentation). Added info on how to do this to the\r
-Imakefile. Thanks to Tom McConnell for this information.\r
-\r
-* Clocks are allowed to go negative. This is mostly for ICS\r
-compatibility, but it affects gnuchess mode too. Also, we give the\r
-time bonus when a player hits the time control boundary even if his\r
-flag is already down. This choice is a bit debatable, but it makes\r
-things look better when you are in TwoMachines mode and gnuchess's\r
-time management screws up causing it to exceed its time limit.\r
-\r
-* Implemented move legality checking code. Moves made with the mouse\r
-or parsed from a file are checked for legality before being made.\r
-This is mostly in preparation for future extensions, such as\r
-human-human play. For now it makes -noChessProgram mode more useful.\r
-\r
-* If the user takes back moves, we restore the clocks to the earlier\r
-settings.\r
-\r
-* We now handle the output of the ICS oldmoves command, including\r
-parsing the game end condition.\r
-\r
-* Added autoCallFlag mode.\r
-\r
-* Fixed glitches in the medium size outline king and rook bitmaps, and\r
-touched up the medium size solid king and outline queen.\r
-\r
-* bug fix: DisplayMove would not display backwardMostMove - 1.\r
-\r
-* Added CallFlag button and removed AcceptMatch. CallFlag is more\r
-important with new ICS, and accepting the current match offer is easy\r
-with the new ICS command "accept" (can be abbreviated "ac").\r
-\r
-* LoadGame and LoadPosition display tail of file name (plus index\r
-number, if any) as title.\r
-\r
-* MachineWhite, MachineBlack, and TwoMachines now work properly from\r
-LoadGame and LoadGame+Pause mode.\r
-\r
-* Use o-o and o-o-o to castle on ICS, not 00 and 000.\r
-\r
-* Stripped out code for old ICS messages; new ICS is now installed.\r
-\r
-* Bug fix: don't offer autosave when paused during LoadGame.\r
-\r
-2.1, patchlevel 7 - Fri Dec 11 17:40:56 PST 1992 - mann@src.dec.com\r
-\r
-* Track change to "Illegal move" message in new ICS.\r
-\r
-2.1, patchlevel 6 -- Tue Dec 8 10:48:44 PST 1992 -- mann@src.dec.com\r
-\r
-* Kludged around bug in keeping comment popup where you put it by\r
-adding borderXoffset and borderYoffset resources that give the width\r
-of the borders added by the window manager. Yucch.\r
-\r
-* Changed searchDepth kludge back to using "help" instead of "bd"; the\r
-latter didn't work because the output contains a line starting with\r
-"White", so we think gnuchess is telling us that White won. Oops.\r
-\r
-* Removed some code that uses an X11R5 feature, XrmGetDatabase.\r
-Without this, the auto font sizing code is harder to make work, so to\r
-keep my sanity I had to change it to affect only the fonts that appear\r
-in the main window and the comment popup, not the other popups. Maybe\r
-this is better anyway.\r
-\r
-* AcceptMatch button now works after a counterchallenge, too.\r
-\r
-* Added code for more variants of messages about games being adjourned\r
-or aborted. These messages need to be unified in new version of ICS.\r
-\r
-* Added workaround for minor bug in ICS; game number on first board\r
-can be wrong.\r
-\r
-* Removed code to say "refresh n" instead of "refresh"; was broken and\r
-wasn't needed anyway.\r
-\r
-* Added missing casts for compilers that distinguish enums from ints\r
-and missing cast in connect call.\r
-\r
-* Added code to recognize "both sides are out of time" draw message\r
-proposed for next version of ICS.\r
-\r
-* Thanks to Danny Sleator and Joe Peterson for bug reports.\r
-\r
-2.1, patchlevel 5 -- Sun Dec 6 19:52:40 PST 1992 -- mann@src.dec.com\r
-\r
-* Removed gcc and CDEBUGFLAGS from Imakefile.\r
-\r
-* Corrected setting of mode to ForceMoves when game file ends or\r
-contains an AmbiguousMove or BadMove. Previous bug was harmless.\r
-\r
-* Added AcceptMatch button and mention of 50-move rule for Draw button\r
-to man page.\r
-\r
-2.1, patchlevel 4 -- Sun Dec 6 02:55:42 PST 1992 -- mann@src.dec.com\r
-\r
-* Now handles revised messages from new version of ICS. New ICS is\r
-not released yet, so this code might change further. Next patchlevel\r
-will remove support for old ICS; both are there now.\r
-\r
-* Initial processing for a new game being watched or played now\r
-happens when we see the first board image. Removes the need to parse\r
-some messages and unifies some code.\r
-\r
-2.1, patchlevel 3 -- Tue Dec 1 19:40:40 PST 1992 -- mann@src.dec.com\r
-\r
-* Handles ICS messages "Draw : neither player has mating\r
-material" and "Draw : White has no material, Black has no time."\r
-\r
-* Added AcceptMatch button for ICS mode.\r
-\r
-* Fixed bug in previous fix to yylexstr().\r
-\r
-* Fixed bugs in code for loading old position files that don't start\r
-with "#" and for handling case where user asked for nth position in\r
-file but there aren't that many.\r
-\r
-* Handles ICS message "* has restored your old game"\r
-\r
-* ResetProc always clears title line now.\r
-\r
-* Don't issue just "refresh" when watching a game; use game number.\r
-Upcoming new version of ICS may need this.\r
-\r
-* Added code to try to prevent user from watching and/or playing more\r
-than one game at a time. There is a race condition inherent here; if\r
-we get more than one board from the game before our command to stop\r
-watching it takes effect, we'll think the user started it again. Not\r
-clear how to fix this.\r
-\r
-* Redid ParseBoard8 to use sscanf. Code is a good deal cleaner now.\r
-Also, we now parse out the game number too, though we don't make much\r
-use of it yet.\r
-\r
-* (Tried to put in a feature that recognizes the current game in a\r
-game file must have ended when we see the start of a new one, but had\r
-to disable it because we have too many false hits with the current\r
-parser, especially in gnuchess listing files.)\r
-\r
-* Moves read from game files or received from ICS are now translated\r
-into canonical algebraic form just like all other moves. Minor nit:\r
-If you use Reset while playing or observing a game in ICS mode, the\r
-game history (including the current board position) is lost, so the\r
-next move of the current game can't be translated.\r
-\r
-* Default fonts now vary with board size, and are chosen by pixel size\r
-instead of point size (since piece bitmaps have a fixed pixel size).\r
-\r
-* Bug fix: An extra Forward was required to skip over time indications\r
-in game files.\r
-\r
-2.1 patchlevel 2 -- Fri Nov 27 23:30:00 PST 1992 -- mann@src.dec.com\r
-\r
-* If you move the comment popup, the next time it pops up it will come\r
-back where you put it.\r
-\r
-* Fixed yylexstr() so calls to it can be interspersed with calls to\r
-yylex().\r
-\r
-* Fixed bugs in Forward/Backward while in LoadGame mode.\r
-\r
-* Changed Save{Game,Position} functions to append instead of\r
-overwriting if file exists. Changed Load{Game,Position} functions to\r
-deal with multiple games/positions per file.\r
-\r
-* Changed load{Game,Position}File resources to trigger automatic load\r
-on program startup. Changed save{Game,Position}File resources to\r
-trigger automatic save after every completed game and on program exit.\r
-\r
-* Added autoSaveGames mode.\r
-\r
-* Fixed bug with PromoPiece in call to MakeAlg from MakeMove.\r
-\r
-* Many changes to get rid of picky compiler warnings and generally\r
-clean up the code.\r
-\r
-2.1 patchlevel 1 -- Fri Nov 27 02:45:00 PST 1992 -- mann@src.dec.com\r
-\r
-* A last minute change before patchlevel 0 went out broke\r
-ParseGameHistory(). Immediately fixed in patchlevel 1.\r
-\r
-Version 2.1, patchlevel 0 -- Fri Nov 27 02:00:00 PST 1992 -- mann@src.dec.com\r
-\r
-* Uses "time" command of gnuchess 4.0 and following to keep clocks in\r
-sync. Still works with older versions without this command; we test\r
-whether the command is present the first time each chess program is\r
-started.\r
-\r
-* File name dialog pops up under the mouse cursor, so that it's got the\r
-keyboard focus if the window manager is using pointer focus.\r
-\r
-* Attempts to move the wrong color piece or an empty square are filtered\r
-out in xboard instead of being passed on to GNU Chess or the ICS.\r
-\r
-* The reason a game ended is now remembered even if you move backward\r
-and forward after it ends. It is forgotten only if you make a move\r
-(which is as it should be---this is now a different game, which hasn't\r
-ended yet). The message saying why the game ended no longer wipes out\r
-the last move.\r
-\r
-* Pause, Backward, Forward, ForceMoves, and EditPosition now work from\r
-TwoMachines mode.\r
-\r
-* Forward and Backward now change only the board display unless you\r
-are in ForceMoves mode. Pause mode keeps new moves that are received\r
-from being displayed on your screen until you unpause (or use\r
-Forward).\r
-\r
-* Added option to ring the bell after opponents' moves.\r
-\r
-* Saved games that start from other than the standard initial position\r
-now begin with a postion diagram as in saved position files. The\r
-loader is modified to understand such save files.\r
-\r
-* Improved error checking when trying to read from gnuchess.\r
-\r
-* Parser understands things that look like time indications, e.g., (0:12),\r
-instead of popping them up as comments.\r
-\r
-* Send "quit" to gnuchess before trying to kill it. I needed this\r
-locally because sending a SIGTERM to rsh was not killing the remote\r
-program on some internal field test systems we have.\r
-\r
-* Merged in code from John Chanak to make xboard a front end to the\r
-Internet Chess Server, and added several improvements of my own.\r
-(These include parsing end of game messages, loading the current state\r
-and previous history of a game that's joined in progress via "watch"\r
-or "load", automatic switch from board style 1 to 8 when needed,\r
-removing irrelevant buttons and adding some new ones, adding the\r
-useTelnet and gateway resources, and miscellaneous code cleanup, bug\r
-fixes, and documentation.) Many thanks to John for writing and\r
-contributing the initial version of this code.\r
-\r
-Fri Oct 30 20:16:40 PST 1992 (patchlevel 25) mann@src.dec.com\r
-\r
-* gnuchess now castles by sending us "o-o" or "o-o-o" (starting with a\r
-preliminary version of 4.0.pl60 that I have). Added code to handle\r
-this. The old format ("e1g1", etc.) still works too.\r
-\r
-* Added code to format moves in normal abbreviated algebraic notation\r
-(for example, e4, exd4, f8Q, Nf6, 0-0) instead of coordinate algebraic\r
-(for example, e2e4, e3d4, f7f8q, g1f6, e1g1). Moves entered with the\r
-mouse or received from gnuchess are translated into this canonical\r
-format for display on the message line or in saved game files. Moves\r
-read from game files are not translated, however; they are shown and\r
-saved just as they appear in the file.\r
-\r
-Mon Sep 14 13:19:01 PDT 1992 (patchlevel 24) mann@src.dec.com\r
-\r
-* It's not really correct to write an ep capture of a pawn on e5 as\r
-fxe5; this should be written as fxe6 because e6 is where the capturing\r
-pawn ends up. Nevertheless, the parser now interprets fxe5 as the ep\r
-capture f5xe6 unless there is a pawn on f4, in which case it\r
-interprets fxe5 as f4xe5. By design, the parser does not flag fxe5 as\r
-ambiguous if there are pawns on both f4 and f5; instead it prefers the\r
-more legitimate f4xe5 interpretation.\r
-\r
-* A move like fxe6 or fe6 is now interpreted as an e.p. capture of the\r
-pawn on e5 if there is one there and e6 is empty.\r
-\r
-* A move like fxe5 can no longer be interpreted as an e.p. capture if\r
-there isn't a pawn on e5 to be captured. Previously this could happen\r
-erroneously if there were pawns on both f4 and f5, and the f4 pawn was\r
-capturing a piece on e5.\r
-\r
-* The parser no longer munges the move it is parsing; in the past, for\r
-instance, it would remove the "x" from a move like dxc5 before echoing\r
-it to the screen.\r
-\r
-* The parser now detects when a move is ambiguous and returns an\r
-error, instead of arbitrarily choosing one possibility as it used to.\r
-\r
-Mon Aug 10 18:40:47 PDT 1992 (patchlevel 23) mann@src.dec.com\r
-\r
-* Added code so parser can handle fully qualified algebraic, e.g.,\r
-Ng1-f3, N/g1-f3, Ng1f3, or even Pe2-e4. The "P" and "/" work only for\r
-fully qualified moves, not generally.\r
-\r
-* Fixed parser bugs in handling moves with rank or file disambiguator,\r
-e.g. N1f3 or Ngf3.\r
-\r
-Mon Jul 6 17:55:32 PDT 1992 (patchlevel 22) mann@src.dec.com\r
-\r
-* AIXV3 patch from Tom McConnell; thanks!\r
-\r
-* After hitting the Backward button we see the last move made instead of\r
-the word "Pausing" displayed.\r
-\r
-* Fixed a couple of problems compiling on IRIX; thanks to Michel Arsenault\r
-and Alan Walsh for bug reports and help with fixes.\r
-\r
-* Added optional display of algebraic notation coordinates along left and\r
-bottom edges of board. This was inspired by some code from Jean-Christophe\r
-Engel; thanks!\r
-\r
-* Swapped EditPosition and Pause buttons to reduce danger of losing the\r
-game in progress by hitting EditPosition when you wanted Backward. Thanks\r
-to Ove Lundberg for complaining (though it bugged me too).\r
-\r
-* Despite one complaint, I kept the feature of changing both clocks when black\r
-makes time control, rather than changing each individually when the player\r
-involved makes it. This is to avoid having it look like White is way ahead on\r
-time while Black is thinking about the last move of the time control period\r
-(i.e., when White has made time control but Black hasn't yet).\r
-\r
-* Corrected clocks to work as in real tournaments. Time is *added* when you\r
-reach time control; previously the clocks were simply set to the length of the\r
-new time period. Also, when a player's flag falls, he still does not receive a\r
-new time allotment at the next time control, but his opponent does still\r
-receive more time if *his* flag has not fallen; previously, time controls were\r
-ignored for both players if either flag fell. I forget who reported this bug.\r
-\r
-* Added a small ESIX patch from Kayvan Sylvan.\r
-\r
-Mon Jun 22 13:24:38 PDT 1992 (patchlevel 21)\r
-\r
-* Added some SVR4 support code from Ronald Cole. It's Greek to me.\r
-\r
-* Note: Stephen Meatheringham reports a bug causing xboard to crash with an\r
-error from the X server when run on a Sun Sparcstation IPX with Solaris 1.0.1\r
-and OpenWindows 3.0. This bug has not been tracked down yet.\r
-\r
-* Fixed a problem with ATTENTION code. On some operating systems, you have to\r
-be even more cautious about when you send a SIGINT to gnuchess, because the\r
-signal handler gets deinstalled each time it is used, and gnuchess does not\r
-reinstall it immediately. In particular, if you send a SIGINT and make an\r
-illegal move or ask for a hint, gnuchess does not reinstall the handler until\r
-*after* you make your next move, so you had better not send a SIGINT before\r
-it. I put a workaround for this case into xboard; I hope there are no more.\r
-\r
-* The ATTENTION code is needed when compiling for the ESIX operating system,\r
-because ESIX has a bug in the FIONREAD ioctl, so the code in gnuchess that\r
-lets you interrupt its thinking on your time just by typing in your move does\r
-not work. Perhaps gnuchess will have a workaround for this eventually.\r
-\r
-* Fixed yet another bug in using XtGetValues; code to inhibit shell resizing\r
-was leaving a null pointer as the place to store the current sizes.\r
-\r
-* Man page fixes: corrected -sl to -sd, updated LIMITATIONS.\r
-\r
-* Added include of <sys/time.h> conditional on HAS_GETTIMEOFDAY. I hope this\r
-works for all systems; on mine, <time.h> and <sys/time.h> are the same file,\r
-but with an #ifndef that makes it harmless to include both.\r
-\r
-* Thanks for reports from Mike Pearlman, Stephen Meatheringham, Kayvan Sylvan,\r
-d87-mal@nada.kth.se, Urban Koistinen, and Ronald Cole.\r
-\r
-Mon Jun 8 11:39:18 PDT 1992 (patchlevel 20)\r
-\r
-* Documented default value of initString and explained what it means. This\r
-paragraph also serves to inform the user that xboard by default will tell\r
-gnuchess to think on his time, something one user apparently didn't understand.\r
-\r
-* Redid -searchDepth (formerly -searchLevel) and -searchTime code. They both\r
-work correctly with gnuchess 3.1 now. The -searchDepth option also works\r
-correctly with gnuchess 4.0. The -searchTime option does not work with\r
-gnuchess 4.0.pl50 or earlier because those gnuchess versions do not have a\r
-working searchTime feature. Instead of having xboard do a half-baked emulation\r
-of this feature by using a 1-move time control, I will be submitting a patch to\r
-the gnuchess folks to restore the feature as in 3.1.\r
-\r
-* Improved clock code. It now keeps accurate track of fractional seconds of\r
-clock running time, if your system has gettimeofday(); if not, it is generous\r
-about them---if a clock has been going for n.m seconds when it is stopped, only\r
-n seconds are charged. Previously, xboard would charge one second immediately\r
-when a clock was started, so if n.m had elapsed when it was stopped, n+1 would\r
-be charged. This should stop xboard from thinking gnuchess has let its flag\r
-fall on the last move of a time control, as it often did before. I also\r
-improved the comments and condensed the code a little. I hope there are no\r
-systems that have X11 and don't have gettimeofday(), but if there are, I'd like\r
-to know what to replace it with.\r
-\r
-* "Flag dropped" messages now show up on the top line, beside the clocks, so\r
-that they don't obscure more interesting messages on the second line.\r
-\r
-* Fixed confusion of NULL and '\000'.\r
-\r
-* Include time.h to get ctime() declaration.\r
-\r
-* Fix to "parser bug" messages in parser.l.\r
-\r
-* Changed code to work with old-fashioned tolower() macro that requires its\r
-argument to be an uppercase letter.\r
-\r
-* Minor fix to some usage error messages; was reversing program name and\r
-erroneous argument value.\r
-\r
-* Thanks to Mitch Wright, Ranier Orth, and Henrik Schmiediche for bug reports.\r
-\r
-Fri Jun 5 13:06:08 PDT 1992 (patchlevel 19)\r
-\r
-* Note: xboard does not seem to work when compiled with gcc 1.40 on a\r
-PS/2 running AIX. It crashes at the sscanf in line 768 of xboard.c.\r
-You can work around the problem by specifying the -timeControl option\r
-on the command line instead of defaulting it. This does not seem to\r
-be a bug in xboard itself; it runs okay on PS/2 AIX when compiled with\r
-MetaWare High C. [But see 2.1.pl8 above.]\r
-\r
-* Removed bogus files from distribution.\r
-\r
-* Changed variable name that conflicted with SVR4 ttyname function.\r
-\r
-* Thanks to Christoph Strozyk for another bug report, and to several\r
-of the folks mentioned under patchlevel 18 for testing it.\r
-\r
-Wed Jun 3 17:50:37 PDT 1992 (patchlevel 18) mann@src.dec.com\r
-\r
-* Added an include of sys/fcntl.h to pick up the definition of O_RDWR for\r
-System V users.\r
-\r
-* Fixed a bug in CatchPipeSignal; was testing the wrong variable to determine\r
-which chess program got the signal.\r
-\r
-* Removed the declaration of strrchr, which was causing problems for some\r
-people, and added an include of <string.h> or <strings.h> instead.\r
-\r
-* Fixed a bunch of type errors uncovered by compilers that check more carefully\r
-than the one I was using. I just patched many of them with casts---typically\r
-cases where a function didn't take the same number and type of arguments as the\r
-X header file prototype said it should---because I didn't see any other way to\r
-fix them. The versions of the X header files that I have don't actually have\r
-full prototypes for these function types; they declare only the return type and\r
-just give the argument types as comments.\r
-\r
-* InitChessProgram returns immediately if chess program died while we were\r
-waiting for it to say "Chess". I think this fixes a bug that could make xboard\r
-crash or go into an infinite loop printing "Warning: Select failed; error code\r
-9" if gnuchess crashed there.\r
-\r
-* Removed code that tries to put the file descriptor used to read messages from\r
-gnuchess into nonblocking mode. I don't see how this kludge could ever have\r
-fixed the problem it was intended to (see below), and it seemed to be causing\r
-a race condition when we were waiting for the initial message from gnuchess\r
-after it started up.\r
-\r
-* Thanks to Richard K. Lloyd, Konstantinos Konstantinides, Mark\r
-Seiden, Erik Schoenfelder, Andreas Stolcke, Rainer Orth, Henry Thomas,\r
-and Kris Van Hees for bug reports and help with fixes.\r

-* 'xboard' suffered from a couple of serious bugs. An initial\r
- size needed to be given to the message label to avoid a race\r
- condition (!) so I gave it some text (otherwise occasionally\r
- xboard would fail because the message widget was 0 width under\r
- MIT X11R4). The sizes needed to be Dimension, not int, because\r
- they were written in by Xt -- on my big-endian box Dimension\r
- is short, causing chaos. Also, I hacked a declaration in for\r
- strrchr() to shut the compiler up -- this is arguably a kludge,\r
- but I couldn't think of anything better; maybe you can.\r
-\r
-Fri May 22 13:40:50 PDT 1992 (patchlevel 16)\r
-\r
-* First real (non-beta) release of version 2.0.\r
-\r
-* Added GNU copyleft notices covering version 2.0 enhancements.\r
-\r
-Thu May 21 12:30:09 PDT 1992 (patchlevel 15)\r
-\r
-* Removed -g from Imakefile.\r
-\r
-* Added casts in parser.l to prevent warning messages from some C compilers.\r
-\r
-* Bugfix: code to exit if chess program couldn't be started had bug in error\r
-message printing.\r
-\r
-Tue May 19 11:58:06 PDT 1992 (patchlevel 14)\r
-\r
-* Fixes one small bug: If LoadGame does not find a game in the file, it resets\r
-xboard to BeginningOfGame mode (as if the Reset button was pressed), instead of\r
-leaving it in LoadGame mode.\r
-\r
-Mon Apr 13 18:32:27 PDT 1992 (patchlevel 13)\r
-\r
-* Improved error handling when gnuchessx crashes. Now displays a message and\r
-enters EndOfGame state without exiting. This should help with diagnosing\r
-gnuchessx problems, since the position and move history are not lost.\r
-\r
-* Debugged man page.\r
-\r
-Version 2.0 -- Thu Apr 2 16:04:54 PST 1992 (patchlevel 12)\r
-\r
-* Added small 40x40 pixel pieces; board size now specified as small, medium, or\r
-large. \r
-\r
-* Improved man page.\r
-\r
-* Saved position files now say "white to play" if it's white's move.\r
-\r
-* SavePosition while in EditPosition mode now gets side to play right.\r
-\r
-* Made "Pawn" the default on edit position menus.\r
-\r
-* Removed "To play" from edit position menus, since it's redundant. Left\r
-support code in so it can be restored if someone wants it.\r
-\r
-* Tightened parser's definition of a move number to help further with skipping\r
-over stuff before the first move.\r
-\r
-* Put back feature of skipping over stuff in game files before a start of game\r
-marker. This helps when loading electronic mail messages that have things\r
-like "00" in the header (looks like castling), or that talk about moves in\r
-running text before the actual game score. Tradeoff is that we can't load\r
-games that don't either have move numbers or say "gnuchess game" just before\r
-the moves.\r
-\r
-* Changed version number to 2.0 because others have used "1.3" for patched\r
-versions of 1.2. Display version number and patchlevel at startup.\r
-\r
-Thu Apr 2 15:30:22 PST 1992 (patchlevel 11)\r
-\r
-* Bugfix: Match started with TwoMachines button now handles the case where\r
-user loaded/edited a position *and* forced some moves.\r
-\r
-* added error message feedback to many cases where the user's button press is\r
-rejected because it isn't allowed in the current mode.\r
-\r
-* added -noChessProgram option to allow use as a passive chessboard without\r
-gnuchess, replacing old buggy scheme that tried to do this automatically when\r
-gnuchess was not found on the search path.\r
-\r
-* parser accepts "=" in front of promotion piece\r
-\r
-* parser accepts ":" notation for captures\r
-\r
-* Removed SwitchSides button to make room for EditPosition. Left code in\r
-place, ifdef'ed out.\r
-\r
-* Added EditPosition mode.\r
-\r
-* Reformatted xboard.c to eliminate long lines.\r
-\r
-* Promotion popup now appears near rank to which pawn is moving.\r
-\r
-* UI improvement: Button representing current program mode is kept highlighted.\r
-\r
-* Bug fix: Hint button is now disabled when machine is on move.\r
-\r
-Sat Mar 21 14:57:37 PST 1992 (patchlevel 10)\r
-\r
-* TwoMachines now works from MachineWhite or MachineBlack mode.\r
-\r
-* ForceMoves and Backward/Forward now work at the end of a game started by\r
-the TwoMachines button.\r
-\r
-* Sends o-o or o-o-o to gnuchess instead of O-O or O-O-O.\r
-\r
-* Bug fix: SwitchSides button is now disabled when machine is on move.\r
-\r
-* Added -searchLevel option and corrected handling of -searchTime to reflect\r
-the way gnuchess really handles command line options instead of what the\r
-documentation used to say. Allowed optional ":seconds" on times.\r
-\r
-Tue Mar 17 21:00:35 PST 1992 (patchlevel 9)\r
-\r
-* Removed non-working code that tried to recover when a remote chess program\r
-could not be started; now exits with a message instead.\r
-\r
-* Now waits for chess program to print its first message (normally "Chess")\r
-before sending it any commands.\r
-\r
-* Matches between two machines can now start from a black-to-play position or\r
-black-to-play opening.\r
-\r
-* Bug fix: The program would sometimes lose track of the board position after\r
-the end of the game, drawing a board full of white pawns next time it got an X\r
-redraw request. Now fixed.\r
-\r
-* Cleaned up handling of illegal moves in game files. Now we just stop reading\r
-and go into ForceMoves mode.\r
-\r
-* Saved games against gnuchess indicate who won (restored and debugged 1.2\r
-feature). \r
-\r
-* Setting -searchTime turns off -clockMode.\r
-\r
-* My trick for setting up a black-to-play position broke in the transition from\r
-gnuchess 3.1+ to 4.0. Installed a different trick that works with both.\r
-\r
-* Bug fix: Was clobbering memory by mallocing one byte too few for the file\r
-name in SetupPositionFromFileProc. This usually resulted in a crash on the\r
-second attempt to load a position from a file.\r
-\r
-Mon Mar 16 16:49:00 PST 1992 (patchlevel 8)\r
-\r
-* Game and position files are saved in CHESSDIR as well as loaded from there.\r
-We actually chdir there, so gnuchess listing files also wind up there.\r
-\r
-* Underpromotion moves from gnuchess really work now.\r
-\r
-Sat Mar 14 14:55:24 PST 1992 (patchlevel 7)\r
-\r
-* Cleaned up lots of bugs and kruft in parser.l. It's a wonder the old version\r
-worked at all. Improved rejection of random text interspersed with the moves.\r
-\r
-* Relabeled buttons to reduce confusion (Play From File --> Load Game;\r
-Setup From File --> Load Position).\r
-\r
-* Bug fix: Doesn't exit at the end of a game that was started by pressing\r
-the Two Machines button.\r
-\r
-* Bug fix: Doesn't get confused if you hit Machine Black (White) while\r
-the machine is already playing black (white) and is on move.\r
-\r
-* Prints "White to play" or "Black to play" after loading a position file.\r
-\r
-* Bug fix: No longer hangs if no start-of-game is found in a game file.\r
-\r
-* More permissive about game file format. The first line is not assumed\r
-to be a header comment unless it starts with "#". We don't insist on\r
-seeing a "1." before the first move.\r
-\r
-* Added pop-up dialog to allow underpromotion. Moving a pawn to the last rank\r
-pops up a dialog to let you select what piece to promote to. Also added code\r
-to handle underpromotion moves from gnuchess or from a game file correctly.\r
-\r
-* Added code to send SIGINT to gnuchess before trying to move, if gnuchess\r
-might be busy thinking on our time. The code is ifdef'ed out because it's\r
-not necessary; only beta-test versions of gnuchess 4.0 at patchlevel 19 or\r
-below require it.\r
-\r
-Mon Feb 24 20:10:22 PST 1992\r
-\r
-* Merged fixes received from Stuart Cracraft and Mike McGann, to iconic mode\r
-and to ShutdownChessPrograms. (They both sent the same fixes.) I did not\r
-install the change that removed "easy" from the initialization string, so\r
-xboard will still try to run gnuchessx in "hard" mode (thinking on opponent's\r
-time) by sending this command.\r
-\r
-Version 1.3 -- Thu Dec 19 18:19:00 PST 1991 mann@src.dec.com (Tim Mann)\r
-\r
-* I've fixed a slew of bugs in this version of xboard:\r
-\r
-* You can now back up from the end of a game, even if gnuchess was playing\r
-against you. Since gnuchess exits upon mate or draw (when it's not in force\r
-mode), this feature works by starting up a new copy of gnuchess and feeding it\r
-the saved starting position and moves. Drawback: the new gnuchess starts with\r
-clocks at the beginning of a fresh time control.\r
-\r
-* Note: the "force" command to gnuchess is a toggle. I fixed a couple of\r
-places in xboard where "force" was being issued when gnuchess was already in\r
-force mode, which resulted in chaos. I don't know if they were in 1.2 or if I\r
-added them myself in the course of putting in new features.\r
-\r
-* ForceMoves button is now legal in PlayFromFile mode. It closes the game file\r
-and lets you force moves (or go Backward) from whatever position you've\r
-reached.\r
-\r
-* The parser now recognizes "white resigns" and "black resigns" (in any\r
-combination of upper and lower case, with or without the closing "s"). These\r
-used to be misinterpreted as meaning "white wins" or "black wins" respectively!\r
-Added "1 - 0" and "0 - 1" as equivalents for "1-0" and "0-1".\r
-\r
-* I removed the parser feature of considering "!" as a comment delimiter.\r
-"!" is so common as an annotation in game scores that this feature seems like a\r
-very bad idea.\r
-\r
-* Added a wait() after each successful call to kill() to avoid leaving zombie\r
-processes around.\r
-\r
-* Removed the feature of putting an indication of how the game ended into the\r
-internal move list when playing from a file. The only benefit of this was that\r
-it would get written back out if you saved the game at that point. This\r
-feature doesn't seem too useful, since you are unlikely to save a game you've\r
-read in without making any changes, and it caused a lot of problems in the code\r
-and user interface. The end condition is still displayed as a message when\r
-it's first read in from the file. End conditions when playing against gnuchess\r
-are still saved, too.\r
-\r
-* programName is now the last file name component of argv[0], not all of it.\r
-\r
-* xboard.c got three compiler warnings due to arguments that didn't match the\r
-prototypes on X toolkit functions. I got rid of them by adding some casts, and\r
-adding extra unused arguments to the ReceiveFromProgram function.\r
-\r
-* As I received it, the distribution had an extra period glued on the front\r
-of every line that started with a period. This broke the manpage in an\r
-obvious way. It also broke parser.l in a nonobvious way that stopped\r
-PlayFromFile from working.\r
-\r
-* Fixed one or two bugs where the clock was started when it shouldn't have\r
-been. I think one example was if you tried an illegal move in ForceMoves mode.\r
-\r
-* Now starts the machine's clock if you hit MachineWhite when white is on move\r
-or MachineBlack when black is on move.\r
-\r
-* Now updates the to-move indicator (highlight on clock display) when you use\r
-Forward/Backward or ForceMoves.\r
-\r
-* gnuchess 3.1+ has a bug that makes it try to think on its opponent's time\r
-even when in force mode; this causes problems with xboard's SetupFromFile\r
-command because gnuchess's saved hint move is garbage after the new position is\r
-loaded, so gnuchess prints out an error message when it tries to think about\r
-what it would do if the user made this move. Here is a patch for gnuchess\r
-3.1+:\r
-\r
-*** nondsp.c~ Mon Dec 2 12:37:18 1991\r
-*-- nondsp.c Thu Dec 19 15:36:06 1991\r
-***************\r
-*** 1223,1229 ****\r
- ok = flag.quit = false;\r
- player = opponent;\r
- ft = 0;\r
-! if (hint > 0 && !flag.easy && Book == NULL)\r
- {\r
- fflush (stdout);\r
- time0 = time ((long *) 0);\r
-*-- 1223,1229 ----\r
- ok = flag.quit = false;\r
- player = opponent;\r
- ft = 0;\r
-! if (hint > 0 && !flag.easy && Book == NULL && !flag.force)\r
- {\r
- fflush (stdout);\r
- time0 = time ((long *) 0);\r
-\r
-* SavePosition/SetupFromFile now handle black-to-play positions. If it's\r
-black's move in a saved position, the line "black to play" is printed\r
-immediately after the board display. Upon loading a position, xboard\r
-looks for "black" at the beginning of this line to determine whether it's\r
-black's move.\r
-\r
-* SetupFromFile now leaves you (effectively) in ForceMoves mode. This\r
-eliminates some cases where the program would get into an inconsistent state,\r
-and hopefully is more intuitive for the user, too.\r
-\r
-* PlayFromFile now leaves xboard in ForceMoves mode after playing through all\r
-the moves in the file. You can use Backward/Forward, make moves, get gnuchess\r
-to join the game with MachineWhite or MachineBlack, etc. The game file can end\r
-with either white or black to play.\r
-\r
-* Backward/Forward now seem to work in all cases. Previously using these\r
-buttons during a game against the machine would get xboard out of sync with\r
-gnuchess's idea of what was going on, resulting in chaos. Now using these\r
-buttons puts xboard in ForceMoves mode; you can bring gnuchess back into the\r
-game using the MachineWhite or MachineBlack buttons.\r
-\r
-Thu Jun 27 15:06:25 PDT 1991\r
-\r
- * Remove comment popups during a reset.\r
-\r
- * Bug in my forward move fix. Didn't work for playgamefile mode.\r
-\r
-Thu Jun 20 15:04:06 PDT 1991\r
-\r
- * Can't do a backward move when it isn't your turn because gnuchess\r
- gets confused. Similar bug for forward move. Do a bunch of moves,\r
- back up move and go forward. These get filtered out now.\r
-\r
- * Put easy back into the initString. This DISABLES easy mode which by\r
- default is ON.\r
-\r
- * New-line wasn't always being added to forward move strings sent to gnuchess.\r
-\r
- * Parsed comments as [ ..............text follows ] into d7d5\r
-\r
- * Long game file comments cause core dumps on HP systems.\r
-\r
- * Multiple uses of the get positition file button got confused\r
- on the second click.\r
-\r
- Minor fixes to the 1.2 release\r
-\r
-Version 1.2 -- Tue Jun 11 17:14:12 PDT 1991\r
-\r
- * For version 1.2, Jeff Kenton, Richard LLoyd, David Jensen, Martin D.,\r
- Bill Schmidt, Scott Hemphill, Paul Vaughan and Bill Shauck all found\r
- a lot of bugs that we put into xboard just to see if they were paying\r
- attention. They were.\r
-\r
- * Changed the protocol that xboard uses to work with the new version of\r
- gnuchessr.\r
-\r
- * There was an off by one error with the clock resetting code. Also,\r
- the clock display highliting was wrong. Thanks to Bill Shauck for\r
- pointing these out.\r
-\r
- * enumerations are not really integers on some C compilers. I added casting.\r
- The new version of gnuchess expects the "go" command for two machine\r
- and machine plays white cases. The whiteString resource is for\r
- compatibility with previous gnuchess versions which get confused by go.\r
- Thanks to Martin D. for catching these.\r
-\r
- * Fixed a bug where the checkmate message wasn't being parsed and xboard\r
- kept playing. Also, the message was added to game file if saved.\r
- Thanks to Scott Hemhill for pointing this out.\r
-\r
- * Fixed a bug where saving a long game, resetting and saving a short game\r
- resulted in appending the end of the long game to the short one.\r
- If a game is just being played out and there is no reason for gnuchessr\r
- to be used, ignore pipe signals. This allows people to use xboard\r
- as a chess board without need for gnuchess. Also, trivially bad moves\r
- such as e2e2 are not passed on to gnuchessr but instead ignored out of\r
- hand. This allows people using xboard as a chessboard with gnuchessr\r
- to pick a piece up, think and put it back down without making a move.\r
- Thanks to Jeff Kenton for pointing these out.\r
-\r
- * Added the CHESSDIR environment variable. Game and position files are\r
- found in this directory. If this variable is not declared, then the\r
- current directory is used. File names starting with / are treated\r
- specially.\r
-\r
- * The bitmap file names were changed so that none exceeded 14 characters.\r
- This is necessary for R5.\r
-\r
- fcntl(from_prog[0], F_SETFL, O_NDELAY);\r
-\r
- The xboard fix was to set non-blocking i/o on the read pipe for gnuchessr\r
-\r
- printz ("Illegal move (no matching move generated)");\r
-\r
- * fixed a problem with the new version of gnuchessr where xboard wasn't\r
- getting gnuchessr error messages for illegal moves. The problem seems\r
- to be fixed *without* any gnuchess changes but this is likely to be\r
- highly system dependant. There should be a new line on line 246 of nondsp.c\r
-\r
- * -iconic doesn't work at all now. The Iconify() does work. This was\r
- a tradeoff and it is really an Xt bug.\r
-\r
- * Fixed a compiler warning for gcc and an error for the IBM RT compilers.\r
- This is the VOID_PROC macro in xboard.h. Thanks to David Jensen for this.\r
-\r
- * If the DisplayWidth or DisplayHeight is less than 800, use small size mode.\r
- Also the size of the name widget was reduced from 500 pixels to 400 pixels\r
- because in small size mode there was a gap on the right.\r
- Changed the default font from fixed to helvetica_oblique14 to:\r
- **-helvetica-bold-r-normal--14-*-*-*-*-*-*-*\r
- helvetica_oblique14 is a font alias not on all R4 systems.\r
- Curiously enough, the 17 point is not available on 75dpi systems\r
- and the 18 point font is not available on 100dpi systems.\r
- Thanks to Richard K. Lloyd for pointing these out.\r
-\r
- * Minor hacks to work with R5 alpha. Had to add an event handler to the\r
- boardWidget to get translations to work. This may go away with the real R5.\r
- Added <Message>WM_PROTOCOLS: QuitProc() for R5 ICCCM compatibility.\r
-\r
- * If the first character of the file is not `1' then the first line\r
- of a game or position file is displayed as the name in a label widget.\r
-\r
- * Added a PopUp dialog for getting file names.\r
-\r
- * Modified the code to use the R4 routines rather than R3 compatibility.\r
-\r
- * Changed the forwards/backwards/readgamefile code to allow a play to step\r
- back and forth in a game. If he steps all the way to the beginning\r
- he has to restart the game. If he gets into a mated position, same problem.\r
-\r
- * Moved the man page from xboard.1 to xboard.man. This makes imake man page\r
- installs work correctly. Thanks to Richard K. Lloyd for pointing this out.\r
-\r
- * Corrected the queening code. XBoard was sending the wrong syntax.\r
- It was sending for example h8(Q) when it should have been sending h8q.\r
- Thanks to Paul Vaughan and Mike McGann for pointing this out.\r
-\r
- * Added a lex parser for algebraic games. It should be easy to use the parser\r
- for other interfaces such as the Microsoft Windows version.\r
- It parses comments of the form [anything] and ! to the end of a line.\r
-\r
-Version 1.1 -- Mon Jan 7 14:46:03 PST 1991\r
-\r
- * Roger Dubar, Konstantinos Konstantinides, Wolfgang S. Rupprecht,\r
- Paul Scowen, Mvh Smidt and Kayvan Sylvan all helped immensely during\r
- beta-testing.\r
-\r
- * older non-ANSI versions of Sun compilers complain vociferously.\r
-\r
- * the remoteShell resource was added for HP-UX systems\r
- and other systems where the remoteShell isn't rsh.\r
-\r
- * -iconic doesn't work properly. If XBoard is opened iconic then\r
- iconifying it later with a keystroke doesn't work. I think\r
- this is an Xt bug.\r
-\r
- * For systems with smaller screens, XBoard can use smaller pieces,\r
- and a smaller board. -bigSizeMode False uses a smaller set of pieces.\r
- These are scaled versions of the large pieces. They look ok but could\r
- be improved.\r
-\r
- * getlogin() does not work in all cases.\r
- It was replaced by getpwuid(getuid())->pw_name).\r
-\r
- * Warning messages get displayed in the message box.\r
-\r
- * Any button restarts a paused game.\r
-\r
- * Kayvan Sylvan contributed a patch for ESIX.\r
- It seems that select() on pipes is broken on his system. We declined\r
- to incorporate his patch though, because it was a work-around for\r
- something that was broken on one system, and selfishly, that system\r
- was not my own. Nevertheless, it is likely that other System V users\r
- on PC's may need to use this patch and it is is included as the file\r
- ESIX.patch. To use it, type\r
-\r
- patch xboard.c ESIX.patch\r
-\r
- * Fixed a bug where hint didn't work. The local version of gnuchessr\r
- had been hacked. The fix was to clone stderr and stdout for gnuchessr.\r
-\r
- * Fixed a bug where a player could play after a game had been finished.\r
-\r
- * The bitmaps have been pushed into the bitmaps directory.\r
-\r
- * Substantially rewrote and simplified the Two Machine code.\r
-\r
- * Added StrStr() because many systems don't have this ANSI function.\r
-\r
- * Added keyboard equivalents. Added an iconify keystroke, C or c.\r
-\r
- * Works with gcc now. gcc complained about casting float constants\r
- as XtPointers.\r
-\r
- * Detect if the visual doesn't support color. If so, run in monoMode.\r
- An alternative would be to detect grayscale visual and use a collection\r
- of gray user interface colors.\r
-\r
- XBoard.clockMode: False\r
-\r
- * For people who don't like or use chess clocks a clockMode switch\r
- has been added. It is on by default. It can be turned off in the\r
- .Xdefaults file with\r
-\r
- * Added a declaration, xtVersion, which will quickly break on R3 Intrinsics.\r
-\r
- * Hal Peterson contributed a new Imakefile.\r
-\r
- * Rewrote DisplayClocks().\r
-\r
- * Rewrote TwoMachinesPlay mode.\r
-\r
- * Konstantinos Konstantinides added the -searchTime option.\r
-\r
- * Substantially rewrote and simplified the clock code. If a game was paused\r
- and then resumed, the clocks were out of sync.\r
-\r
- * Fixed a bug in HandleUserMove() where the user could make a move while the\r
- machine was thinking. The fix detects and ignores these moves. onMove\r
- was not being used and was removed.\r

+
+2009-10-30 20:02:40 -0700 H.G. Muller <h.g.muller@hccnet.nl>:
+use xtell instead of tell in wchat
+
+2009-10-28 20:35:06 -0700 H.G. Muller <h.g.muller@hccnet.nl>:
+prevent buffer overflow
+
+This is a buffer-size adjustments to prevent the JAWS version from
+crashing when it has to read out loud very long comments.
+
+2009-10-28 02:17:16 -0700 Tim Mann <tim@tim-mann.org>:
+Further copy/paste fixes
+
+We needed to implement the XA_TARGETS target in order for more
+sophisticated apps to really believe we put anything on the clipboard
+they can use.
+
+2009-10-27 23:57:25 -0700 Tim Mann <tim@tim-mann.org>:
+Make copy/paste position and game use clipboard, bug #27810
+
+Copy actually sets both the clipboard and the selection for
+convenience and compatibility with the old way of doing things.
+Paste pastes from the clipboard by default, but the new -pasteSelection
+option lets you get back the old behavior of pasting from the
+selection.
+
+2009-10-27 15:44:28 -0700 H.G. Muller <h.g.muller@hccnet.nl>:
+switch focus to the board after loading a game
+
+2009-10-27 15:32:07 -0700 H.G. Muller <h.g.muller@hccnet.nl>:
+fix for bug #27826: fixed autoDisplayComment
+
+apparently the -autoDisplayComment option was not working,
+not even in WinBoard. This patch should fix it,both for WB and XB.
+(Unfortunately xboard.c and winboard.c were using a different name
+for the same front-end variable I needed, so I had to change one of them.)
+
+2009-10-27 12:24:56 -0700 H.G. Muller <h.g.muller@hccnet.nl>:
+fix for bug #27826: ported two options to xboard
+
+also updated the documentation
+
+2009-10-27 12:22:36 -0700 H.G. Muller <h.g.muller@hccnet.nl>:
+fixed jaws version
+
+turns out the new mouse handler broke the JAWS patch, as I discarded
+the function IsPromotion. I adapted it to call HasPromotionChoice instead.

+more work on variant switch
+
+the previous solution to the cosmetic problem of displaying a wrong shuffle
+in an ICS game that was observed from the very start unfortunately turned
+out to cause a real error in diplaying a stored game through the smoves
+command, for variants not using the FIDE setup as standard.
+
+This patch displays the position from before setting up the start position
+of the new variant, but does setup boards[0] to the initial position of that
+variant. (If this is a wrong shuffle, it is thus ot displayed, and a new board
+will immediately be sent from the ICS to correct the shuffle.)

+holdings update and regression fix
+
+The holdings-update patch was not yet satisfactory, because FICS seems to send
+holdings both before and after the board! And those received before did overwrite
+the holdings received after the previous board. I know tried to fix that in a kludgey
+way, by hiding a flag in the board that tells if the holdings have already been written
+by the ICS or not, and ignore new holdings when they are. (Except in bughouse,
+where holdings updates cannot be tied to a particular board and multiple updates
+between boards are normal. (I hope?).)
+
+I also undid a regression in my previous fix for the minor graphics problem,
+and solved it in a slightly different way to prevent flicker.
+
+2009-10-22 21:23:39 -0700 H.G. Muller <h.g.muller@hccnet.nl>:
+improved mouse handler

+I improved the mouse handler in a way which will preclude disappearence of pieces

+is now fixed, by removing the prefixing.

+fix for bug #8847: moving backward while examining on FICS not reported to engine
+
+I moved Daniel's code that backs up the engine when a bord with a
+lower number is received to a place where it is always done in zippy mode,
+rather than only when the engine is analyzing.
+
+Apart from taking back moves, there was also the case where the
+user moves forward by more than one move (usually immediately to
+end-of-game). In this case a new movelist is fetched from the ICS
+to recover the moves that were skipped. But this assumes that the
+engine is at the start of the game and feeds all these moves to the
+engine. So the engine had to be reset in this case to stay in sync.

+Adjustment to joining to work around server not always including space.
+
+This patch implements commit 98aa02bda540f17f1f50be00e494efafe439b004
+into the updated joining routine. This issue seems not to be server
+variance, but instead the server electing to omit the space between
+words when it occurs at exactly your width setting (-1 actually).
+
+This patch makes the joiner add back the space just like the referenced
+commit. Note: this is just a workaround to a server issue-- the joiner
+actually joins correctly before this patch.

+2009-10-09 00:04:51 -0600 Eric Mullins <emwine@earthlink.net>:
+Updated navigation accelerators, fixing ICS problems.
+
+Recent changes to the navigation accelerators were in the wrong
+accelerator table. Since the goal was to correct non-JAWS versions
+back to 4.2.7 behavior, I updated it to how 4.2.7 did it, but still
+retained the #ifdef JAWS conditional compilation.
+
+On an ICS, the navigation keys took control away from the ics
+client to navigate the game. The update requires the ALT key to
+be pressed, but it works identical to 4.2.7, not causing an
+unexpected focus back to the board window when you're just editing
+text.

+fixed premove recapture problem;promotion popup appearing on
+obviously illegal moves; promotions in Superchess and Great Shatranj
+
+1) the premove recapture problem
+2) the promotion popup appearing on obviously illegal moves (the 1. e2a8
+problem)
+3) promotions in Superchess and Great Shatranj, where the piece can now be
+selected from the holdings

+2009-10-05 21:01:32 -0700 Arun Persaud <arun@nubati.net>:
+bugfix: segfault when invalid option argument was given (bug #27427)
+
+when given a wrong argument to an option (e.g. -tc 0) xboard aborts
+before setting up the window, but tried to write a message to the
+messageWidget which doesn't exist at that point.
+
+2009-10-05 20:05:00 -0700 H.G. Muller <h.g.muller@hccnet.nl>:
+small improvement for JAWS version
+
+This is a patch to make JAWS read out any comments when /autoDiplaycomment=true.
+As focus does not stay on the Comment window, the comment was not spoken otherwise.
+
+2009-10-05 20:02:50 -0700 H.G. Muller <h.g.muller@hccnet.nl>:
+updated to winboard internationalization scripts
+
+Also a slight improvement of the internationalization scripting,
+to prevent it from crashing on messages containing a slash.
+
+2009-10-05 20:01:53 -0700 H.G. Muller <h.g.muller@hccnet.nl>:
+new forceIllegalMoves option
+
+The -forceIllegalMoves option uses setboard or edit to force a position
+when an engine refuses the move leading to it by an "Illegal Move" message.
+Especially for engines using the edit command this was a bit tricky,
+because of the a2a3 kludge to avoid using the white and black commands.
+
+2009-10-05 01:01:54 -0600 Eric Mullins <emwine@earthlink.net>:
+removed _winmajor if not defined so that VC 2008 can compile the project
+
+The oldDialog variable should just be set to 0 in all cases now, and
+as such, legacy code supporting the old dialog ought to be removed.
+The test for _winmajor is against < 4, which is always false at present,
+causing oldDialog to be 0 in every conceviable circumstance.
+
+2009-10-04 09:58:29 -0700 Arun Persaud <arun@nubati.net>:
+getting ready for 4.4.1 release
+
+2009-10-02 20:47:01 -0600 Eric Mullins <emwine@earthlink.net>:
+Simplified future version changes.
+
+Added a numeric version to config.h that is now used in winboard.rc
+instead of being hard-coded there. Just be sure to preserve the
+proper format (4 comma-separated 16 bit integers) or else it won't
+compile.
+
+2009-10-02 16:56:01 -0700 Arun Persaud <arun@nubati.net>:
+updated version number to 4.4.1.pre
+
+should have done this straight after the last release, but forgot...
+
+2009-10-02 16:48:03 -0700 H.G. Muller <h.g.muller@hccnet.nl>:
+worked on premove bug
+
+I made an attempt to make premove unsensitive to a race condition,
+just in case the premove problem was caused by that (which seems unlikely,
+but in any case I added some debug printout to test this).
+
+2009-10-02 16:41:12 -0700 H.G. Muller <h.g.muller@hccnet.nl>:
+fixed loading of saved games via command line
+
+the variables forwardMostMove and backwardMostMove where set to zero
+at the wrong place.
+
+2009-10-02 16:39:20 -0700 H.G. Muller <h.g.muller@hccnet.nl>:
+small fixes for the JAWS version
+
+* I moved saying 'check' by the JAWS version to where castling also benefits from it.
+* I made sure the check symbols are also recognized on promotion moves
+* In the non-JAWS version, define the plain arrows as shortcut keys for the button bar
+
+2009-10-01 16:50:28 -0600 Eric Mullins <emwine@earthlink.net>:
+Fixed bug dereferencing garbage, causing crash.
+
+Commit fa8be4a3fc5d81e9ec1f6c218fcf55c95d34fd10 included code to free the
+resultDetails of the gameInfo structure. That exact code exists a few lines
+above where it was added. None of these free() calls finish by setting the
+member to NULL afterword, therefore repeated attempts to test/free() the
+members result in an attempt to free() memory winboard no longer owns, and
+an eventual crash.

+Add resource ID for new Mute menu item.
+
+I know this was probably done by HG, and simply left out of

+
+2009-09-29 22:04:25 -0700 H.G. Muller <h.g.muller@hccnet.nl>:
+bugfix for protocol extensions: egtbpath -> egtpath
+
+A new and very bad bug was discovered in the implementation of
+the protocol extensions: XBoard sends a command "egtbpath" to the
+engine in stead of "egtpath" from the protocol specs.
+After discussion on WB forum it was decided that egtpath was better
+than the egtbpath I originally had proposed, and I changed it accordingly,
+but I had not realized that this string occurred TWICE in backend.c,
+depending on if matched the -defaultPathEGTB of -egtFormats option.
+I only changed the first occurence.
+
+2009-09-27 12:27:44 -0700 H.G. Muller <h.g.muller@hccnet.nl>:
+fix for edit-position "moves" being sent by XBoard to the engine
+
+2009-09-27 12:25:25 -0700 H.G. Muller <h.g.muller@hccnet.nl>:
+Engine did not start playing when out of GUI book on second move with white
+
+2009-09-27 12:24:30 -0700 H.G. Muller <h.g.muller@hccnet.nl>:
+Opening Engine #1 Settings crashed XBoard when there were no
+text-edit options in the dialog (to which to set keyboard focus)
+
+
+2009-09-27 12:18:35 -0700 H.G. Muller <h.g.muller@hccnet.nl>:
+added a "Mute All Sounds" item in the WinBoard Options menu, on Eric's request
+
+2009-09-27 12:15:20 -0700 H.G. Muller <h.g.muller@hccnet.nl>:
+Updated the RTF docs for the chat windows, engine-settings dialog,
+/keepAlive option and new game-list tag
+
+2009-09-27 12:14:25 -0700 H.G. Muller <h.g.muller@hccnet.nl>:

+command-line options
+
+2009-09-27 12:11:49 -0700 H.G. Muller <h.g.muller@hccnet.nl>:

+
+2009-09-27 12:10:38 -0700 H.G. Muller <h.g.muller@hccnet.nl>:

+
+2009-09-27 12:05:32 -0700 H.G. Muller <h.g.muller@hccnet.nl>:
+rewrote wevalgraph for better frontend/backend separation
+
+I have finished re-writing the eval-graph code to have some
+front-end / backe-end separation, something I had already started on my
+holiday in Norway (when I had no internet :-) ).
+The new code now appears to work exactly like the old code,
+and I guess it could be ported to gtk comparatively easily.
+
+2009-09-27 12:00:51 -0700 H.G. Muller <h.g.muller@hccnet.nl>:
+fix for keepalive and chat window
+
+I made a fix to the keepAlive option so it does not send the date command
+to the ICS after every move. This required changing ScheduleDelayedEvent()
+so that it does not execute the event if a new identical one gets scheduled.
+I also added the option to XBoard. Affects xboard.c (DOS!) and winboard.c
+
+(This also cures the regression of the winboard.c copyright patch)
+
+I extended the chatbox patch to also listen to channel tells, and divert
+them to a chatbox for that channel number. Affects
+backend.c and wchat.c
+
+That should make those patches fully operational. No docs for either of them
+yet, though.
+
+2009-09-27 10:36:23 -0700 H.G. Muller <h.g.muller@hccnet.nl>:

+
+2009-09-27 10:35:58 -0700 H.G. Muller <h.g.muller@hccnet.nl>:

+2009-09-27 10:35:13 -0700 H.G. Muller <h.g.muller@hccnet.nl>:
+fixed the HAVE_LIBXPM-dependent compile errors
+
+2009-09-27 10:24:47 -0700 H.G. Muller <h.g.muller@hccnet.nl>:
+added a chat window to keep track of multiple conversations
+
+The chat-window patch affects:
+winboard.c, backend.c, winboard.rc, resource.h, backend.h, and adds
+the file winboard/wchat.c, which also affects makefile.gcc and makefile.ms.
+
+In addition I added a new option -keepAlive, which affects
+common.h (in addition to winboard.c and backend.c).
+
+As I had to modify backend.h, I also defined the -reset option type there,
+which we are going to add later. This required some changes
+to suppress warnings in wsettings.c.
+
+2009-09-27 10:22:16 -0700 Arun Persaud <arun@nubati.net>:

+
+I was going through old WB forum posts, and I encountered a

+be properly set (actually: cleared) after setting up a position
+in Edit Position mode (as opposed to pasting a FEN).
+
+2009-09-03 23:11:18 -0700 Arun Persaud <arun@nubati.net>:

+2009-09-03 22:30:18 -0700 H.G. Muller <h.g.muller@hccnet.nl>:
+updated polyglot protocol
+
+I added a new option type "-reset" to the protocol for the new option feature.
+4.4.0 does not implement it yet, but Michel wants it for future Polyglots,
+and I think it is best to update the protocol in one big swoop.
+So I want to already include it in the specs now. (engine-intf.html)
+I made xboard's response to an unknown option type compliant
+with the new protocol specs.

+
+2009-08-31 20:29:49 -0700 H.G. Muller <h.g.muller@hccnet.nl>:
+workaround for error message for missing pieces used in variants
+and initstring bugfix: error messages showed for non-existing pieces
+showed up for old user supplied pixmaps.
+Loading a pixmap of the king for the missing pieces now.
+
+Another bad bug surfaced: the -initString argument does not work in any
+XBoard version! (Including 4.2.7b) The escape sequences for linefeed in
+the string are not understood: -initString "new\nrandom\n" actually sends
+the \ and n to the engine (which then does not recognize the line as a
+valid command)!
+
+So I also added a patch to expand escape sequences in the InitString and
+ComputerString command-line options.
+
+2009-08-31 20:27:24 -0700 H.G. Muller <h.g.muller@hccnet.nl>:
+updated installe script
+
+I re-organized the doc files in the install, so they now all go in the
+WinBoard\doc folder (and none in the root). I so included the COPYING
+and COPYRIGHT files there. This required some updates of the links in
+some html files, and of the menu link to README.html in the install script.
+I also fixed an error with the current directory
+in the menu short-cuts of some engines (which started in the fonts folder,
+and could not find the opening book there...).

+
+make tried to compile zippy even when --disable-zippy was given.
+Also fixed a bug in xboard.c where #ifdef instead of #if was used
+to test for ZIPPY (it's either 0 or 1, so we need #if). Also added
+some special checks for OS X, not sure if these will do it, but it's a start;)
+
+2009-08-22 19:09:54 -0700 Arun Persaud <arun@nubati.net>:

+2009-08-22 17:47:44 -0700 H.G. Muller <h.g.muller@hccnet.nl>:
+A small cosmetic change in the size of buttons
+inside a groupbox of the Engine-Setup dialog.
+
+2009-08-22 17:32:14 -0700 H.G. Muller <h.g.muller@hccnet.nl>:
+make xboard usable with UCI engines
+
+I made a small patch in xoptions.c (where the corresponding Engine Settings
+dialog was for XBoard), to make it at least usable for UCI engines: I now
+divide the options over upto 4 columns, if there are too many to fit into
+a single column. This seems to work. Still looks very ugly, but it is
+functional.
+
+2009-08-22 17:30:05 -0700 H.G. Muller <h.g.muller@hccnet.nl>:
+fix premove for winboard
+
+This might fix the illusive premove problem. In 4.2.7 the code was not properly
+indented, and this led to an unbalanced braces error that I then fixed the
+wrong way. Click-click premoves did only work after clicking the toSquare twice.
+It might be that they actually did work after clicking it once,
+but that the highlights were not displayed (although set)
+for lack of a display refresh.
+
+2009-08-22 17:28:11 -0700 H.G. Muller <h.g.muller@hccnet.nl>:
+fixed bug for double saved games
+
+This patch should solve the problem with doubly saved games when XBoard is
+closed. I calculate a cecksum of each saved game now (including move comments),
+and suppress saving if the checksum is not changed.
+
+2009-08-22 17:25:58 -0700 H.G. Muller <h.g.muller@hccnet.nl>:
+fixed xengineoutput.c, to keep the duplicated code identical to that of wengineo.c.
+
+2009-08-22 17:24:08 -0700 H.G. Muller <h.g.muller@hccnet.nl>:

+
+2009-08-22 17:07:10 -0700 H.G. Muller <h.g.muller@hccnet.nl>:
+fixed several bugs in the backend and added some more polyglot support
+
+* I added recognition for the new UCI3 option types that are recognized in the WB
+option features, to make sure this version is compatible with future Polyglots.
+Also fixed a bug that failed to strip an asterisk prefix from the first
+combo-box item.
+
+* I fixed the ICS-time-in-PGN bug.
+
+* I fixed a bug which caused a space to be missing when long lines broken up by
+an ICS were joined.
+
+2009-08-22 17:02:58 -0700 H.G. Muller <h.g.muller@hccnet.nl>:

+output.
+
+2009-08-22 16:23:32 -0600 Eric Mullins <emwine@earthlink.net>:
+Beginnings of installer for 4.4.0. HGM asked me to forward the nsi file,

+temporary fix for pre-select
+
+As a temporary kludge I replaced looking into the holdings for the piece type
+by figuring out which piece would belong on the clicked holdings square.
+This is a non-trivial process, as it depends on which pieces participate
+in a certain variant.
+
+2009-07-30 00:19:37 -0700 H.G. Muller <h.g.muller@hccnet.nl>:
+changed click-click moves
+
+I got complaints about the way XBoard 4.4.0 handles click-click moves,
+in particular changing the selected piece after selecting King
+(for which I suppressed interference with FRC castling in a rather brutal way).
+People tell me it is very annoying that clicks sometimes don't work to select a piece.
+WinBoard uses refined logic in the back-end to handle this, but the XBoard
+front-end is not interfaced with that yet.
+(This would require a major rewrite of the mouse handler.)
+This temporary patch suppresses this behavior in all variants that do not support
+Fischer castling, and even there only exhibit it for Rook-after-King selection
+(which will be interpreted as an attempt to enter a castling move as K x own R).

+MSVC 6.0 still works, but I had to change the target windows
+version to 0x500 which causes warnings about building beta
+applications. This is all due to the use of MENUBARINFO data
+type in the jaws binary. You can reduce the WINVER to 0x0400
+safely if you are not building a JAWS binary, and MSVC 4.x
+will work fine.

+
+I integrated the JAWS patch now into WinBoard in such a way that the
+JAWS and standard version can use the same resource file. This new
+winboard.c contains the improved dialog layot of the JAWS version,
+but none of the menus and JAWS-specific acclerator keys. The latter
+are now generated at run time by code in jaw.s. As a result jaws.h
+could be cancelled, as there the JAWS-specific defines are no
+longer needed outside jaws.c (now the .rc does not use them), and
+is incorporated in it.

+2009-07-12 10:04:30 -0700 H.G. Muller <h.g.muller@hccnet.nl>:
+fix for Animation of castling moves in Chess960
+
+Animation of castling moves in Chess960 turned out to sometimes make the
+king disappear from the display. For the time being I patched this in
+xboard.c to suppress animation of FRC castling moves altogether. As FRC
+castlings internally are represented as KxR, the to-square does not make
+sense anyway, which made the animation look very weird even when it led
+not to a king disappearance act. And the Rook move of a castling is never
+animated.

+2009-07-11 16:54:53 -0600 Eric Mullins <eric@hiarcs.(none)>:

+
+* Cleanup: moved "Some definitions required..." from winboard.c to config.h,
+and combined some definitions from borland w/ MS.
+
+* Changed internal HtmlHelp return type and 4th argument to facilitate various
+compilers. These changes, while not strictly adhering to HtmlHelp() conventions,
+won't impact anything since the function modified is internal only.
+
+* Modified HtmlHelp return values to integer to silence warnings.
+* Added help.c to the project in makefile.gcc & makefile.ms.
+* Fixed duplicate resource in winboard.rc.
+
+2009-07-09 22:08:15 -0700 H.G. Muller <h.g.muller@hccnet.nl>:

+
+* JAWS support
+* help files should now work under Vista (the user has to have either
+ a program to view old windows help files or to view html-files installed)
+* I fixed the tabbing between all windows that were added according to Tim's sugestions.
+* I added typing in of a move number in the move type-in dialog as a shortcut
+ to going to that position by use of the < and > buttons. Mainly intended to
+ ease life for the blind, but I think it can be generally useful.
+ (Although the move-history dialog provides that functionality too,
+ this is quicker if you don't happen to have it open.)
+* I added typing of a FEN in the move type-in dialog in Edit Position mode.
+ (Which could not be used without mouse at all, and is defective
+ in crazyhouse even with mouse, as there was no way to populate holdings.)

+major overhaul of the -stickyWindows feature
+
+I did a major overhaul of the -stickyWindows feature.
+The game-list and ICS-interaction windows are now also sticky.
+I also added a form of stickiness when the main window is resized;
+edges of auxiliary windows sticking to the right or bottom side of
+the main window stay attached when the window resizes
+(due to nr of board squares or their size). The way the window
+coordinates are saved in the .ini file is now relative to the
+main window, and some dummy options are added to be able to
+recognize right- and bottom-edge sticking, and reconstruct that
+when WB starts up with another board size. Also added are
+volatile options to ensure there will be space for auxiliary windows
+above and left of the main window.

+
+changed the format of the autoKibitz: score/depth in stead of depth/score,
+as in PGN. I also supress the ICS time for the move now in the PGN
+if extended info is available. When enhancing the functionality of
+the autoKibitz command (using the opponent engine kibitz for the saved PGN)
+I discovered that the xengineoutput.c in our tree was obsolete,
+and contained a routine of which the arguments were no longer compatble
+with the call from backend.c, and caused segfaulting. I copied in
+the corresponding routine in wengineo.c, which was compatible. That the
+compiler did not flag this is a sign of badly organized code, I suppose...
+
+The enhancement itself affected backend.c.

+
+I had overlooked one place from which the FEN writer
+(of whicf I changed the argument types), which made WB crash
+if you copied a FEN (or PGN that cotained FEN) to the clipboard.
+I must have overlooked a warning during compile, or some depedency
+is not correct in the makefile. Anyway, wclipboard.c had to be changed.
+I also moved adjudication of some losing conditions to before tetsing
+for stalemate, (e.g. in atomic, if your king get destroyd you lose,
+even if you have no moves after that because it was your only piece.).
+this affects backend.c.
+I had used the same bits in the rule-modifier flags for indicating
+mandatory capture as was already used for indicating FRC-style castling.
+This led to frequent illegal move calls in FRC... (moves.h)

+added option for work-around for some FRC engines in regards to FRCFENs
+
+It suddenly occurred to me that I had promised on CCC to include an option
+to provide a work-around for the problem that some FRC engines do not
+understand FRC FENs (and thus do not play at all under WinBoard,
+as FRC always has to begin with sending the initial position).
+So I added the options -firstNeedsNoncompliantFEN, -secondNeedsNoncompliantFEN.
+This affects winboard.c and xboard.c, (for defining the option),
+common.h, backend.h, backend.c, (for implementing it),
+xboard.texi and winboard.rtf (decribing it).
+This option provides users with a means to always force the FEN castling field
+to KQkq (but can be used for many other work-arounds as well).

+
+There also seemed to be a bug with the shuffling of opening positions;
+I had changed the declaration of the position number from
+long long int to u64 to comply with MSVC, but this suppressed shuffling
+completely. I now changed it to int. I recently noted a problem with true
+randomizing anyway: this was based on srand(time()), but time() apparently
+did not change fast enough, so that starting several games in rapid succession
+(because the book line contained a 3-fold repetition) produced identical games.
+So I now seed the random once and for all during startup, based on the msec of
+the time mark, and removed the other calls to srand().

+
+2009-06-13 09:07:07 -0700 H.G. Muller <h.g.muller@hccnet.nl>:
+Fixed bug in atomic patch that interfered with non-atomic variants
+
+2009-06-10 21:46:11 -0700 H.G. Muller <h.g.muller@hccnet.nl>:
+fixed different use of engine option compared to Polyglot
+
+it turns out the new Polyglot uses a sightly different version
+of the GUI->engine option command than the one I proposed
+(and implemented in XBoard; Michel sneaked in an '=' sign
+between the NAME and VALUE of the option, to allow for
+more unambiguous parsing. I guess in principle this is a good idea,
+so I adapted XBoard to Polyglot rather than the other way around.
+The result is that there are canges in xboard.c, and the documentation.
+I noticed that I unjustly had internationalized the option strings
+to be send to the engine in xoptions.c; this was of course nonsense,
+as this was WB protocol. So I undid that too.

+automatically test ini file extension for files from commandline option @filename
+
+The winboard.c is a patch that automatically tries indirection files on the
+command line (@filename type arguments) also with an extension .ini if the name itself
+did not match any existing file and contained no period. This saves the user typing the
+.ini all the time (which I started to find pretty annoying while working on the installer

+
+2009-06-04 18:27:26 -0700 Arun Persaud <arun@nubati.net>:
+cleanup: got rid of a lot of files that are not needed for a new release
+
+lots of documentation was available in several places,
+old unused source files and not used graphics file were floating around
+in the tree. This should clean up most of it. No need to keep these files
+around, especially since we are using version control.
+
+2009-05-29 18:56:06 -0700 H.G. Muller <h.g.muller@hccnet.nl>:
+Added the Action-menu items that allow the user to adjudicate
+ongoing games in Two-Machines mode. This was an already existing
+backend function from Winboard_x; I only had to create a menu item for it
+to be called. Due to an oversight I had forgotten to do that so far.
+(Logically, I should have done it in the 4.3.5 release,
+where I updated the XBoard menus to conform to the WinBoard menus.)
+
+I tested them, and they seem to work. (As expected.)

+
+2009-05-28 22:11:11 -0700 H.G. Muller <h.g.muller@hccnet.nl>:
+corrected 'animate dragging'
+
+I finally figured out how the 'animate dragging' works in XBoard,
+so that I could add code to do the unstacking of multiple pieces
+in the holdings, rather than always leaving an empty square while
+you drag them. (And then suddenly re-growing the remaining pieces
+as you make the drop.) It does not look as fancy as in WinBoard
+yet, because the counts still only decrease when you release the
+piece, rather than when you lift it. But this is not nearly as
+disturbing as leaving empty holdings (if only temporarily) when
+you still have pieces there.
+
+2009-05-28 22:06:15 -0700 H.G. Muller <h.g.muller@hccnet.nl>:
+Added comand-line options -debugFile (as synonym for -nameOfDebugFile,
+as WinBoard also has these synonyms), and -engineDebugOutput

+
+* 06/27/2004: added simple icsEngineAnalyze for xboard
+
+* 06/26/2004: added icsEngineAnalyze for winboard: Analyze observe games

+
+* 02/11/2004: Winboard: Added color lines for the ics interaction
+console if zippy used
+
+* 02/09/2004: Added mousewheel support for winboard. Play moves
+backward and forward with the mousewheel.
+
+xboard/WinBoard 4.2.7 -- Fri Nov 28 13:36:00 PST 2003 -- Tim Mann
+
+* 11/26/2003: In WinBoard, setting the -debug flag now logs ICS output
+to WinBoard.debug too. (This isn't needed in xboard because ICS
+output already goes to stdout, so it's easy to capture along with the
+debug output on stderr.) This was issue #280 in the ToDo file.
+
+* 11/23/2003: Cleaned up some minor problems in cygwin.mak. Thanks to
+Hans Werner Strube for the problem report.
+
+* 11/23/2003: Updated the default list of chess servers in
+winboard/defaults.h. Deleted two that appear to be dead and added a
+new one that is active.
+
+* 11/19/2003: Swapped icon_white.bm and icon_black.bm in XBoard.
+Hopefully this will get them the right way around by default on more X
+window managers. I wish I understood this better.
+
+* 11/18/2003: Implemented a simple 32-bit random number generator for
+WinBoard, replacing the Windows rand(), which ranges only up to
+0x7fff. Formerly on Windows, only zippy.lines sayings that started in
+the first 32767 bytes of the file could ever be used. This was issue
+#505 from the ToDo file.
+
+* 11/16/2003: The xboard man page and info files are now built from a
+common set of texinfo source files, and the xboard man page now covers
+cmail as well. Formerly, ever since the texinfo file was first
+contributed to the project, it was separate from the man page and the
+two files had to be updated in parallel, making for a maintenance
+nightmare. To make combining the files possible, I took the Perl
+script "texi2man" from the GNU Units project and added support for a
+larger subset of the texinfo markup language. I then carefully
+compared the old man page and old texinfo file to make sure the latest
+and clearest words survived into the new combined texinfo file. It
+would be great to merge in WinBoard's help file too, but that's a
+larger project. It would have to be heavily conditionalized to
+deal with differences in features between XBoard and WinBoard.
+
+* 11/15/2003: Cleaned up and applied a small patch from Daniel
+Mehrmann, to stop overly long PVs in thinking output from causing a
+buffer overflow crash in backend.c.
+
+* 11/5/2003: When a chess engine sends a "telluser" command (including
+the cases where "tellall" or "tellopponent" acts like telluser), the
+information now goes into a nonmodel popup that is automatically
+dismissed when the user clicks anywhere on the board. This fix is
+more significant on WinBoard, where formerly you got a fully modal
+dialog that had to be dismissed by clicking on OK before anything else
+could happen. The bug was issue #406 in the ToDo file.
+
+* 11/1/2003: Removed email addresses from this file to reduce spam
+load, as it gets linked to from the Web.
+
+* 11/1/2003: Updated READ_ME and winboard/READ_ME.txt.
+
+* Modified xboard and winboard makefiles to be able to build the
+project in the new combined directory structure.
+
+* Applied a small security fix to pxboard, from Martin Maeok.
+
+* Fixed a bug in the game list dialog. The change in 4.2.6 to opening
+games in text mode (meant to avoid getting extra \r's into comments)
+caused a new bug in determining seek offsets when parsing a game file
+to form the game list. Also, the change was incomplete; on some code
+paths games were still being opened in binary mode. Thanks to Lenik
+Terenin for reporting the offset bug. I've now gone back to always
+using binary mode when reading game files, and I've fixed the comment
+bug by adding code to remove \r's from parsed comments explicitly. I
+still use text mode for writing game files so that games written by
+WinBoard will have Windows-style line endings.
+
+* Fix for minor bug in WinBoard installer. If you chose a non-default
+destination directory, the default directory was still used for a
+couple of unimportant things, namely setting the App Paths registry
+keys (unused by WinBoard) and trying to copy the existing WinBoard.ini
+file to WinBoard.old. I inherited this bug from the InstallShield 5
+sample template. Thanks to "l.d." for noticing the incorrect keys.
+
+* Patch from Chris Priest: when two engines are being run through rsh,
+avoid reusing the same stderr port for both. I'm not sure why this
+should be needed, but it's harmless, at least.
+
+* Bugfix: The kludge to deal with old engines that give an error
+message because they don't know the "st" command was too sloppy; it
+could hit on an "st" substring anywhere in an error message. GNU
+Chess 4 is the only engine I know of where the kludge was needed, so I
+changed the kludge to match a longer, more GNU-specific string.
+
+* Changed the WinBoard self-extracting installer to choose a unique
+temporary subdirectory name within the Windows temp directory instead
+of always putting wb-setup directly in temp. Besides being better
+practice, this avoids the need to deltree wb-setup first, which
+occasionally alarms someone who thinks that deltree is only used by
+trojans to delete all your files. (Yes, I'm serious.)
+
+* Fixed a bug where FICS-style "wild/0" strings were not parsed as the
+proper wild type. The "/" was not being skipped.
+
+* Fixed a WinBoard bug where temporary files created by game
+copy/paste were being created in the root directory of the current
+drive instead of the TMP directory and were not always deleted on exit.
+
+* Fixed a small bug in winboard.c's ErrorDialog() function. Thanks to
+"Ron" (no last name given). The bug might have caused a problem when
+pressing OK or Cancel in an error dialog when more than one error
+dialog was being displayed, but I'm not really sure.
+
+* Removed a hack that worked around a bug in very old versions of
+Crafty, where it would sometimes reply "illegal move" to a "."
+command. The hack kept us from recognizing real illegal move messages
+in analyze mode from engines that don't respond to the "." command.
+Thanks to Fabien Letouzey for the report.
+
+* Fixed a bug in the xboard version of GetDelayedEvent. It would
+return the most recently scheduled event even if it had already fired.
+This caused at least one visible error: in -ics -xreuse mode, starting
+the engine again and seeing another "feature done=1" would re-run the
+initialization code in InitBackEnd3, including the code that opens the
+connection to ICS. The WinBoard version didn't have this bug. Thanks
+to Bob Hyatt for the bug report.
+
+* The promotion popup for ICC wild 26 (giveaway) now includes King.
+Thanks to Fredrik Josefsson for the bug report.
+
+* The first game in a file (or being pasted from the clipboard) can
+now start with a bare move -- no PGN tags, no move number "1", etc.
+Suggested by Shane Harrelson. One could imagine taking this farther
+and accepting something like "e4 e5 1/2-1/2 d4 d5" as two games, but
+I haven't done that.
+
+* Bug fix: xboard didn't really accept a paste of multiple games,
+contrary to what I wrote when adding the feature to WinBoard in
+4.2.4. Now it works in both.
+
+* Fixed generic start/end of game messages to work on chess.net, where
+they put ratings in parens after the player names.
+
+* Updated config.sub and config.guess to newer versions from
+automake-1.4p5-2. This makes configure work with MacOS X + X11.
+
+* Bugfix: when examining a game fragment on FICS where black plays
+first, don't show two "(0:00.000)" times on the initial "none" move.
+
+* If TestLegality is on and one of the engines makes an illegal move
+in TwoMachines mode, it forfeits immediately. Formerly the game would
+get stuck at that point and the engine that made the illegal move
+would eventually lose on time.
+
+xboard/WinBoard 4.2.6 -- Fri Feb 1 22:26:31 PST 2002
+Tim Mann
+
+Another small bugfix release.
+
+* Put in a small change from Alexander Mai to allow xboard to build in
+an OS/2 EMX environment.
+
+* Fix WinBoard-only bug where editing a PGN file with comments would
+insert more \r characters before the \n after every Load/Save cycle.
+For some unknown reason we were reading the files in "rb" mode but
+writing them in "a" mode, so we kept the \r characters on reading and
+added an extra one on writing. Fix: change the "rb" to "r". Thanks
+to Joel (last name not given) for the bug report.
+
+* Put the arguments to rsh/remsh in the right order for better
+portability. Thanks to Michael Kalisz.
+
+* FreezeUI is now implemented in WinBoard; it was previously only
+implemented in xboard. This function prevents the user from entering
+moves or other commands while we are waiting for an engine to
+initialize itself. Implementing it fixes a bug where the user could
+start a game (etc.) during feature negotiation. One of the symptoms
+of this bug was that we could send "new" one or move moves *after* the
+first game started!
+
+* Fixed some handle leaks (WinBoard only), including a nasty one that
+leaked one handle per command sent to ICS. Thanks to several folks
+who helped characterize the bug and tried to look for leaks.
+
+* We now install and look for the info file in ${prefix}/share/info
+instead of ${prefix}/info. The latter is still the default in
+autoconf, but the former is currently used in Red Hat Linux and
+probably elsewhere.
+
+xboard/WinBoard 4.2.5 -- Sat Dec 15 11:42:51 PST 2001
+Tim Mann
+
+* Changed the bundled GNU Chess 5.02 in the WinBoard package to
+include a much smaller book and to use much less hash table space by
+default (8 MB transposition table, 0.5 MB pawn evaluation table). The
+large book included with 4.2.4 made the WinBoard download too big for
+some people, and the default hash tables were larger than the
+available physical memory on some people's computers. I built the
+small book by running Crafty's "small.zip" book line collection
+through a Perl script that makes it look enough like real PGN games
+that the GNU Chess book builder will accept it. The script and some
+minor patches to GNU Chess 5 are available in the WinBoard source
+distribution and at http://www.tim-mann.org/gnuchess.html.
+
+* Fixed a bug in the code that deals with engines that complain that
+"time" and "otim" are illegal moves. This was a new bug in 4.2.4.
+
+* Revamped the implementation of ToStart in analysis mode. Formerly
+there was some ill-conceived code that would try to get back to the
+start of the game by doing a "new" command (and all the followup
+commands that requires) while remaining in analysis mode. This is
+problematic for engine authors to support, though it works with
+Crafty. This code was trying to solve the problem of ToStart being
+slow because the engine would try to start an analysis after every
+"undo" command all the way back to the start. But ToEnd already had a
+much better solution to this problem, and now ToStart does the same
+thing: we exit from analysis mode and enter force mode instead,
+make/unmake moves to get to the end/start of the game, and then
+reenter analysis mode.
+
+* Formerly, Zippy could try to start playing a game before the engine
+was initialized; that is, during the initial timeout for protover 1
+engines, or before "feature done=1" for protover 2 engines. We now
+wait until the engine is initialized before connecting to ICS, which
+fixes this in the common case. If you turn off engine reuse for
+multiple games (that is, if you give the -xreuse option), there could
+still be problems; see item 503 in the ToDo file. Thanks to Dieter
+Buerssner for the bug report.
+
+* Bugfix: All WinBoard versions since the merge with WinBoard Plus
+(but not xboard) have had a bug in changing the PeriodicUpdates,
+PonderNextMove, and ShowThinking options from the menu. The bug
+mostly just caused changing these options during a game to not take
+effect until after the next reset. For TwoMachines games, though,
+changing PonderNextMove just before the game would take effect
+immediately for the second engine but not until the next game for the
+first engine. Thanks to Koundinya Veluri for the bug report.
+
+* Bugfix: In 4.2.4, we sometimes got confused when trying to leave and
+reenter analyze mode. One symptom was that Analyze File did not work.
+Thanks to Igor Syry for the bug report.
+
+xboard/WinBoard 4.2.4 -- Sun Dec 9 14:56:30 PST 2001
+Tim Mann
+
+* WinBoard now includes GNU Chess 5.02 in place of GNU Chess 5.00.
+
+* WinBoard's PasteGameFromClipboard will now handle a paste with
+multiple games in it, popping up the game list dialog. xboard
+already did this. Suggested by Robert Gerstman.
+
+* We now use the "clearboard" command on ICC where appropriate.
+
+* Bugfix: don't generate a bogus "variant normal" command to an engine
+for the loadable ICC wild types that we internally flag as
+VariantLoadable. Also clarified the message that Zippy sends when
+declining such wild games -- it can't deal with the possibility of
+loading an arbitrary position into the game. Thanks to Dieter
+Buerssner for reporting the problem. It would be nice to be able to
+actually play these wild types some day; presumably there would have
+to be an option to either send "loadgame" with a specified position,
+or to deal with an opponent sending it.
+
+* If we get a holdings message from ICS when we thought we were
+playing normal chess, we now try asking for a move list so that we can
+find out from the header what's really happening. Formerly we guessed
+bughouse in this case. Response to a comment from Gian-Carlo
+Pascutto.
+
+* Fixed two longstanding bugs in the clock code. These affected only
+play between a user and a local engine, or between two local engines,
+not ICS play. (1) The last fractional second used by a player before
+moving and virtually pushing his clock was being charged to his
+opponent instead of to him. (2) The time and otim commands were being
+sent to an engine before the (buggy) fractional second update was
+done. The second bug was pretty harmless in itself, but the first one
+was serious. Many thanks to Peter Rosendahl for carefully diagnosing
+and reporting these bugs!
+
+* Changed WinBoard timestamp key. Nothing is changed other than the
+key and a recompilation. ICC may phase out the old key soon; if they
+do, you'll need to use the timestamp.exe from WinBoard 4.2.4 or later
+to connect to chessclub.com.
+
+* Fixed an xboard-only bug where most dialogs would not take keyboard
+input unless the mouse was actually over the dialog, even if the
+dialog window had focus. Thanks to Jason Varsoke for the bug report.
+
+* Bugfix; Remember to send time and otim commands to engine before
+sending playother. Thanks to Bob Hyatt for the bug report. Also
+fixed a bug where time and otim were sometimes sent even with feature
+time=0.
+
+* Added small patches from Wilkin Ng that are meant to fix a crash in
+CopyGameToClipboard and a "can't unlock clipboard memory" error in
+PasteTextFromClipboard, under Windows 2000.
+
+* Changed cygwin.mak to not use -mno-cygwin. In other words, it now
+uses cygwin1.dll instead of the mingw libraries. This works around
+bugs in fileno() and stat() that I encountered in mingw. (fileno
+seems to always return 0. stat fails because the library routine uses
+a different definition of struct stat than the header files provide.)
+Thanks to Robert Gerstman for reporting the symptoms these bugs caused
+when WinBoard was compiled with Cygwin.
+
+* Added -showButtonBar option. This lets you delete the << < P > >>
+buttons and thus widen the message widget a bit.
+
+* Added code to address a very obscure bug. If an engine dies and
+needs to be restarted while in one of the analyze modes, it was not
+getting put back into analyze mode. This bug should not really ever
+have gotten tickled unless reuse was turned off and the engine sends
+game end commands (such as 1-0) when a game ends by rule while in
+analyze mode. The next version of the protocol spec will say that
+engines should not do that, but version 2 and earlier didn't address
+the issue.
+
+* We now use the FICS "iset ms 1" feature to get times in ms instead
+of seconds. Thanks to DAV for email telling me about this feature.
+
+* Changed clock display to show tenths of seconds for 9.9 seconds and
+less, instead of 0.9 seconds and less as before.
+
+* It has been discovered that Zippy can play simuls on ICC (but not on
+FICS). If you arrange for Zippy to send the ICC command "simulize" in
+the -zippyGameStart string, it will accept additional games while
+playing. Zippy will use the same engine for every game, so whenever
+it switches opponents, the engine's state will be reset with the "new"
+command. This will of course weaken its play, so don't enable simuls
+if you want your engine to have the highest possible rating. Zippy
+was never designed to work with simuls; it just works by accident, and
+it hasn't been tested much. So please report any bugs you notice, but
+don't expect them to be fixed rapidly. Thanks to Paul McGuire for
+noticing that this works.
+
+* Bugfix: Suppress the direct command to engine popup if there is no
+engine. In WinBoard this case used to cause a crash. Thanks to
+"Dargon" for the bug report.
+
+* Bugfix: formerly we did part of the engine initialization for the
+very first game too soon, before feature negotiation. One result of
+this is that engines would never get the "ics" command for the first
+game.
+
+* Lengthened timeout to detect protocol version 1 chess engines to 10
+seconds. This should reduce problems with protocol version 2 engines
+that are slow to initialize missing the timeout and not getting a
+chance to send their feature commands before the first game starts.
+
+* Klaus Friedel says that adding a short sleep to WinBoard after
+starting a new chess engine solves a problem that occurs under Windows
+2000, in which engines sometimes don't see the initial command(s) from
+WinBoard and hang. I don't understand how that can happen, but the
+sleep is harmless, so I've put it in. Others have also reported what
+may be the same problem, so hopefully this will fix it for them too.
+
+* Bugfix: editing the Result field in EditTags will no longer cause a
+later crash. Thanks to DAV for a clear bug report that let me
+reproduce the problem.
+
+* ICC wild 28 is now recognized as shatranj, but it is not supported.
+You might be able to play it by turning off Test Legality.
+
+* Formerly we would always turn off "feature time" if the engine
+printed an error message with the string "time" or "otim" in it; now
+we do that only if the message comes before the engine makes its first
+move. This change is useful because some engines spew a lot of bogus
+error messages about commands they don't fully parse, so something
+like "result 0-1 {White lost on time}" could generate such a message.
+Engines shouldn't do that, but if they do, mysteriously turning off
+"feature time" is not a good way to react.
+
+* Fixed an infrequently occurring Zippy bug: formerly, resuming from
+adjournment by position (that is, with GetMoveList turned off) or
+starting/resuming a wild game (nonstandard starting position) would
+try to set up the position without putting the engine into force mode
+first. That was probably tolerated by most engines, but if the
+position was black-to-play and the engine hadn't set feature
+setboard=1, then the fake "a2a3" move (which we use as a kludge to get
+black to be on move before sending the edit command) would appear to
+be a real move, and the engine might reply to it! This bug could also
+be seen when trying to use Zippy to play a simul -- something that
+Zippy was never designed to support, but which seems to mostly work
+anyway. Thanks to Paul McGuire for sending a WinBoard.debug file that
+showed the bug occurring. Some other cases of resuming adjournments
+or starting games from nonstandard positions may have been broken too;
+I think I've straightened out the problems.
+
+* Agreeing to a draw in the human vs. local engine case formerly did
+not work if the human offered first; now it does. A human's
+unsolicited offer is considered valid until he makes another move.
+Thanks to Bruce Moreland for the bug report.
+
+* Bugfix: We used to look for just "fr" in Event tags or strings from
+ICSes to recognize Fischer Random games. This caused a lot of false
+matches. Now we look for "wild/fr" instead, which is what FICS uses.
+
+* Bugfix: Clicking on a move in the MoveList window only updated the
+displayed position; if a chess engine was active, its state was not
+updated. Thanks to Alejandro Dubrovsky for the bug report.
+
+* Bugfix: The "resign" command from engine to xboard formerly did not
+work in ICS (Zippy) mode.
+
+* Bugfix: Formerly we would register a garbage premove if the user
+clicked on a piece, then clicked on an edge or outside the board. Now
+such an errant click is ignored.
+
+* Bugfix: GameEnds would send "exit" to an engine in analyze mode even
+if we did not actually want to leave analyze mode.
+
+* Bugfix: "feature pause" was being rejected. We don't currently use
+it, but that is no reason to reject it. Thanks to Gian-Carlo Pascutto
+for the bug report.
+
+* Bugfix: when "partner" needed to be sent both to ICS and the engine,
+Zippy was erroneously sending the ICS prefix character to the engine
+too. Thanks to Gian-Carlo Pascutto for the bug report.
+
+* Zippy now declines challenges when the engine is not yet ready to
+play again, instead of ignoring them. This is needed so that the
+server will let the opponent repeat the challenge. It might be better
+to remember such challenges and accept them when the engine is ready,
+but that would be a bit more complicated to implement.
+
+* Bugfix: Zippy's emotes didn't work on FICS because there, "i" is a
+built-in alias for "it", not a real command. So sending "$i foo" gave
+an error message instead of doing "it foo". We now leave out the
+alias-suppressing prefix for emotes.
+
+xboard/WinBoard 4.2.3 -- Mon Feb 19 19:55:05 PST 2001
+Tim Mann
+
+* Bugfix: The error message "Variant X not supported by gnuchessx"
+formerly could pop up even in -ncp mode.
+
+* Fixed an xboard bug in premove highlighting. If you had
+HighlightLastMove turned on, premoves got highlighted in
+highlightSquareColor (yellow) instead of premoveHighlightColor (red).
+
+* Modified premove again. Now we are back to displaying the move
+locally immediately after sending it to the server, as in versions
+prior to 4.2.1. This is good because it lets you register your next
+premove sooner. As a better fix to the problem that the change in
+4.2.1 had been trying to address, we now suppress animating the
+opponent's move if you have a premove reply pending. However, it's
+probably still a good idea for you to turn off AnimateMoves entirely
+if you are trying to play extremely fast games.
+
+* Removed an erroneous patch that left zombie chess engines around
+when both sigterm and reuse were turned off. (Bug was in xboard only,
+not winboard.)
+
+* Bugfix: loading a game with autostepping did not work for games with
+PGN result "*" (unfinished). This bug was introduced in 4.1.0, caused
+by some outdated code that was supposed to leave you in EditGame mode
+after loading an unfinished game. I fixed this, and also changed it
+to leave you in EditGame mode after loading *any* game, but without
+changing the tags to say it's an edited game. It's not really clear
+whether that is the best thing is to do here -- ideally, perhaps, the
+tags should change to say "edited game" if you actually make any
+changes, but that is harder to make work.
+
+xboard/WinBoard 4.2.2 -- Tue Feb 6 20:00:00 PST 2001
+Tim Mann
+
+* Fixed a problem introduced in 4.2.1. In -zippyPlay mode, 4.2.1
+started sending the initString immediately after the old game ended,
+but then when the next game started, it would still send "force" and
+another initString. Another problem was that the first initString put
+the engine out of sync with the displayed board position, though that
+might not usually have been noticeable. This is now changed to do a
+full Reset at the end of the previous game, and avoid doing a Reset at
+the start of a new game if we are still in BeginningOfGame mode.
+
+* Fixed some limitations in -zippyPlay mode. The engine was not being
+fed the moves or history of games that were displayed but not being
+played, so it would get confused if you tried to do something like
+examine a game, then enter EditGame mode from somewhere in the middle
+of the game.
+
+* Made a small change so that cygwin can compile xboard for Windows
+(an X server is required to run it). Thanks to Volker Zell. Most
+people would probably prefer to run WinBoard on Windows, however; note
+that cygwin could already compile WinBoard.
+
+* Added some missing documentation to engine-intf.html: It is okay to
+send "feature done=0" even before you receive the xboard and protover
+commands, if this is needed to give your engine enough time to
+initialize. See engine-intf.html for more discussion.
+
+* Bugfix: "feature done=0" did not work for the second engine; now it does.
+
+xboard/WinBoard 4.2.1 -- Sat Feb 3 19:52:26 PST 2001
+Tim Mann
+
+* Bugfix: in Zippy mode with feature san=1, the elapsed time was being
+sent to the engine after the SAN move; for example, "e4 (0:01)" was
+sent instead of just "e4".
+
+* It seems that scroll wheel mice with incompletely installed software
+(under Windows 95, at least) can send repeated middle button up events
+when the wheel is turned. Moved QuickPaste from middle button up to
+middle button down to avoid problems with this.
+
+* A premove is now sent *before* the opponent's move that it replies
+to is animated. The premove itself is no longer displayed (or
+animated) when sent; instead, it is displayed when the chess server
+echoes it back as a board update.
+
+* Bug fix: in -xreuse mode, xboard was only sending command line
+arguments to the engine the first time it was started. (WinBoard
+didn't have this bug.)
+
+* In -zippyPlay mode, we now initialize the chess engine for a new
+game immediately after the old game ends. (In -xreuse mode, this
+means starting a new engine process; in the default -reuse mode, it
+just means sending "new".) If the engine supports ping, we don't
+accept challenges until the "new" has finished. This should help
+avoid losing time (re)initializing the engine after the game starts.
+
+* We now handle the new FICS field in style 12 that says whether the
+clocks are ticking.
+
+* whiteFlag and blackFlag are now reset whenever an ICS board image
+arrives, giving autoflag a fresh chance to work.
+
+* Suppressed "geometry error" debug messages unless -debug flag is given.
+
+* Bugfix: avoid core dump on Solaris with -debug flag, caused by
+passing NULL to a %s format in GameEnds.
+
+* Added -firstProtocolVersion and -secondProtocolVersion. This will
+allow use of extremely broken engines that hang or die when given the
+"protover 2" command. It should be rarely if ever needed.
+
+* Zippy now strips highlights from player names in the Creating
+message; previously the ratings would not be extracted from this
+message properly if you had set the highlight variable.
+
+* Bug fix: Zippy with -zp but not -zt used to be fooled by false
+partner tells inside channel tells; e.g.:
+Garf(24): Garf (your partner) tells you: sit
+
+* Bug fix: when an engine reported its name with the new "feature
+myname=" command, we had been putting just that name into the window
+title even when in TwoMachines mode.
+
+* By default, WinBoard no longer uses the new feature introduced in
+4.2.0beta of keeping the ICS menu, ICS server list, and lists of chess
+engine command lines in separate files; instead, the lists are back in
+the winboard.ini file. This gets rid of some problems where the
+separate files could not be opened because the working directory was
+not set to WinBoard's installation directory.
+
+* WinBoard command lines and ini files now have another optional
+syntax for quoting an option value. All characters within { } curly
+braces are interpreted literally except for '}' itself. SaveSettings
+now uses this syntax for string values that contain a backslash or
+newline and do not contain a '}'. This should address the problem
+that the separate .ini files had been meant to fix; engine command
+line lists can now be written without \-escapes.
+
+* Fixed three bugs in relaying moves between engines in TwoMachines
+mode: an engine would be sent SAN if the *other* engine had set
+feature san=1, a relayed SAN move did not end with a newline, and
+feature usermove was not implemented for relayed moves.
+
+* Fixed several bugs in exiting: File/Exit would sometimes hang;
+timestamp/timeseal would not get killed off; an engine crash would
+cause error messages to be printed recursively until stack overflow.
+
+* Fixed a bug in the code to detect which ICS is in use and adapt to
+it; the chess.net case was broken.
+
+* Removed the leading alias-suppression character when sending a move
+to ICS, because it seemed to break accuclock on chess.net.
+
+* Fixed a bug where a FICS prompt like "10:01_fics%" would be matched
+as finger note number 10, causing a problem detecting when the user is
+logged in.
+
+* Added tellicsnoalias command to protocol.
+
+* Changed st command in protocol back to old behavior.
+
+* Added done=0 feature to protocol, to lengthen initial timeout.
+
+* Added missing -colorSeek command line option to xboard. (Was
+present in WinBoard.)
+
+* Bug fix: setting feature reuse=0 was not working.
+
+xboard/WinBoard 4.2.0beta -- Sat Dec 16 16:34:56 PST 2000
+Tim Mann
+
+* Setting -searchTime no longer turns off -clockMode. Note that when
+-searchTime is set, some engines may search for the lesser of
+searchTime and the amount of time their normal clock management would
+dictate, while others will disable their normal clock management and
+always search for exactly searchTime.
+
+* Fixed WinBoard bug where on Windows 2000 (and maybe Windows 98) the
+ICS Interaction window would scroll back to the top whenever it filled
+to capacity and WinBoard trimmed some text off the top.
+
+* Changed xboard dragging so that the center of the dragged piece is
+forced to be over the mouse cursor. (WinBoard dragging already worked
+that way.) This should avoid confusing cases when you start a drag
+with the mouse near the edge of a square -- formerly most or all of
+the piece could be over one square but the mouse cursor over another.
+Suggested by DAV.
+
+* Added move list window for xboard. Code contributed by Manuel
+Hoelss and re-hacked a bit by me. Performance of this window is poor,
+because the implementation regenerates the entire window contents
+whenever anything changes. It's hard to avoid this when using the
+Athena List widget, though we could be a little smarter and notice
+when the current move number has changed but the move list has not.
+There are also several drawing problems caused by bugs in the Athena
+Form and List widgets. The window should not really allow a
+horizontal scroll bar, but the bugs are much worse if I turn it off.
+In both Xaw and Xaw3d, the List widget tries to resize itself when
+XawListChange is called, even if you tell it not to; and what's worse,
+if the widget cannot resize itself to be large enough to avoid
+clipping any of the list item, it does not change the list! Arrgh.
+On top of that, the Xaw Form widget is very buggy in XFree86 4.0.1
+(X11R6.4.3).
+
+* The OK button in the WinBoard startup dialog is now simply disabled
+if none of the radio buttons is selected, instead of bringing up an
+error dialog. Suggested by Ted Milbaugh.
+
+* Used ping to address the worst of the race conditions in the
+protocol. Now if an engine supports ping, we ping it after sending
+the "new" command and after trying to place it in force mode at the
+end of a game. When a ping has been sent and the corresponding pong
+has not yet come back, we (1) ignore or undo any moves the engine
+sends, (2) ignore game end messages (such as "offer draw", etc.) from
+the engine, (3) ignore thinking output from the engine, (4) delay
+starting the next game if in -matchGames mode, (5) in -zippyPlay mode,
+respond to challenges with a polite message to try again soon instead
+of accepting them. There are a few more things that should be done
+(and item 5 might not be quite what we want), but it's hard to fit
+them all into the existing code.
+
+* Patched the version of GNU Chess 5.00 included with WinBoard to
+support protover, feature, setboard, and ping, and to fix some minor
+bugs. See gnu500+.patch.
+
+* Changed the GNU Chess 4 kludges for missing "st" and "sd" commands
+to be invoked only if the engine gives an error message for "st" or
+"sd", and to always use protocol commands instead of engine
+command-line options. See "Idioms" in engine-intf.html.
+
+* Added new protocol command "protover 2" to tell the engine what
+version of the protocol is in use. Version 2 is still compatible with
+old engines; see engine-intf.html.
+
+* Add new protocol command "feature ..." The engine can send this in
+response to the protover command command, to say what extended
+protocol features it would like to enable, etc. xboard responds
+"accepted F" or "rejected F" for each feature F that is set. See
+engine-intf.html.
+
+* Added new protocol command "setboard <fen>". This is an alternative
+to "edit", used only if the engine says "feature setboard=1".
+
+* Added new protocol command "ping <msg>". The engine is supposed to
+respond "pong <msg>". This gives us a tool to fix some race
+conditions in the protocol, but it is not used to the fullest yet.
+
+* Added new protocol command "tellopponent". This will do a "say" if
+you're on a chess server in Zippy mode, or pop up an information
+dialog otherwise.
+
+* Added new protocol command "tellall". This will do a "kibitz" if
+you're on a chess server in Zippy mode, or pop up an information
+dialog otherwise.
+
+* Added new protocol command "tellothers". This will do a "whisper" if
+you're on a chess server in Zippy mode, or do nothing otherwise.
+
+* Changed the WinBoard /icsNames, /icsMenu, /firstChessProgramNames,
+and /secondChessProgramNames options to accept a filename preceded by
+"@", meaning to find the value in the file. Changed the defaults to
+use this feature, with filenames icsnames.ini, icsmenu.ini, fcp.ini,
+and scp.ini. This should make it easier for users to edit the values,
+since one less level of quoting is needed, and each value is in its
+own file, not mixed into winboard.ini. Those who upgrade from an
+older winboard version and already have a winboard.ini file will not
+automatically have these values moved to a file; that has to be done
+by hand if desired.
+
+* We now strip .exe from engine names for "name" command, tags, etc.
+
+* Allowed WinBoard input widget to hold more than one line. You can get
+a newline into the widget with copy/paste or with Ctrl+Enter.
+
+* Fixed an xboard bug where the [P] button would appear in the
+opposite highlight state from what it should be after being pressed.
+
+* We now use the "/" or "$" alias suppression feature on the chess
+servers, to avoid problems if the user inadvertently aliases a
+needed command to something else.
+
+* Changed the method used to deiconize xboard in AutoRaise and cmail.
+This may fix bugs under some window managers where after
+deiconization, the board window was mapped but nothing was drawn
+inside.
+
+* Preliminary, partial support for playing several chess variants
+against a local engine or editing variant games. The -variant option
+must be given on the command line or WinBoard startup dialog; there is
+no menu. The current variant is not displayed (except in the
+Tags/EditTags window). Many variants will not work quite right even
+if the engine supports them; see item 326 in the ToDo file for
+details.
+
+* Added a workaround to detect the variant type when examining a
+scratch wild game on an ICS.
+
+* Fixed two cases where "variant" command should be sent to the engine
+when necessary but was not: loading a game from a file and restarting
+a dead engine. Thanks to Gian-Carlo Pascutto.
+
+* Added missing support for FICS games that start from a bsetup position
+with Black moving first.
+
+* Fixed a bug in loading a file from the game list window while in
+Analysis or AnalyzeFile mode. This now leaves us in AnalyzeFile
+mode, analyzing the new file.
+
+* Fixed a bug in loading games with a comment before the first move.
+
+* Fixed a bug in handling LoadGame (or -lgf) with -td 0.
+
+* Added a command line option to select an initial minor mode from the
+Mode menu. This should satisfy requests from a couple of users with
+special applications.
+
+* Fixed a problem where some things in WinBoard's General Options
+dialog box were grayed out at the wrong time.
+
+* We look for a few messages from the chess engine pipe that are
+intended to catch problems starting an engine via rsh, such as "No
+such file". Moved code so that these strings won't match until other
+protocol messages have been looked for, and documented the messages in
+engine-intf.html.
+
+* Fixed the WinBoard bug that sometimes made the console input box
+white-on-white even when not in password-entry mode.
+
+* Small changes to WinBoard to be compilable with the latest Cygwin
+net release (as of 10-16-2000). Thanks to Mark Schoenberg.
+
+* Recompiled GNU Chess 5.0 for WinBoard with the latest Cygwin net
+release (as of 10-16-2000). Also rebuilt the book just to be sure,
+since I had one bug report about it. It came out identical and seems
+to work fine.
+
+* Added messages for some common InstallShield errors instead of just
+printing InstallShield's stupid error code numbers.
+
+* Added -firstComputerString and -secondComputerString, allowing you
+to suppress or change the command that is sent to a chess engine when
+its opponent is another computer.
+
+* Added "configure --with-Xaw3d" to allow use of Xaw3d widgets instead
+of Xaw widgets in xboard. Thanks to Johnny C. Lam of the NetBSD
+project. I've left Xaw as the default because Xaw3d is too ugly.
+
+* The version of the Xaw Form widget released in XFree86 4.0.1
+(X11R6.4.3) has a bug that causes xboard to display the button bar
+on top of the message widget. I've reported the bug and have
+installed a kludge workaround into xboard.
+
+xboard/WinBoard 4.1.0 -- Sun Sep 17 17:30:14 PDT 2000
+Tim Mann
+
+* Merged Winboard Plus 4.0.8 from Mark Williams into xboard
+ source pool. Status of Winboard Plus features in xboard:
+
+ - White pieces now have borders, but the implementation is
+ completely different from WinBoard's; see below.
+
+ - Options menu not changed, probably won't be.
+
+ - Copy&paste support working, using Mark's changes to backend.c, Ben
+ Nye's changes to xboard.c for FEN positions, and some code of my
+ own in xboard.c for PGN games.
+
+ - Premove hooked up and working. No pre-first-move, though.
+
+ - ICS Alarm hooked up and working.
+
+ - Auto-flip working.
+
+ - PGN Training mode hooked up and working.
+
+ - Improved menu item enable/disable working.
+
+ - Improved >> button working.
+
+ - Auto activate board working. I changed this to be optional; you
+ might not always want it, especially in Zippy mode.
+
+ - Blindfold working.
+
+ - Documentation updated.
+
+* Fixed more colorization bugs. Commands like "message foo tells you:
+xxx" and "tell 33 tells you: xxx" will no longer generate bogus
+colorization.
+
+* Added low-tech sound support to xboard, by invoking an external
+program on a filename for each sound to be played.
+
+* ICC wild 27 is now recognized as VariantAtomic, and it sets the
+"ignore check" flag, but is not otherwise supported.
+
+* Converted the piece bitmaps from .bm to .xpm for use with xboard's
+xpm support. (An .xim version was not created.) Wrote a shell script
+using ImageMagick to do the conversion and to bucket fill from
+coordinate 0,0 with the background color. Used xpaint by hand to
+clean up a few pieces where background color "leaked" into the inside
+or didn't flow all the way around the outside, then a sed script to
+fix up color names and bitmap names in the xpaint output. If any more
+sizes are added later, they should be straightforward to convert with
+reference to the existing scripts. With this conversion, not only do
+the white pieces now have dark borders, but (unlike with WinBoard) the
+light details on the black pieces are opaque.
+
+* If the XPM library is found when building xboard, the new xpm pieces
+are compiled in as the default. External bitmap (or xpm) pieces can
+still be used by giving the -bitmapDirectory (or -xpmDirectory)
+option. If the XPM library is not found, the old bitmap pieces are
+the default. In this case external bitmap (or xim) pieces can be used
+by giving the -bitmapDirectory (or -xpmDirectory) option. There is no
+way to compile in xim pieces.
+
+Winboard Plus 4.0.8 -- Sat Aug 5 15:51 PDT 2000
+Mark Williams
+
+* Bugfix release.
+
+* Main menu now visible in Win NT. Thanks to Microsoft for creating a
+compiler which auto-mutilates the WinBoard.rc file so that the menu is
+displayed under Win 98 but not Win NT. I fixed the problem by hand editing the
+.rc file. Sigh.
+
+* "Reset game" now works properly when invoked from Analysis mode when two
+engines are present. Correction of bug introduced in Winboard Plus. Thanks to
+Mogens Larsen for reporting the bug.
+
+* Pasting a FEN position with Black to move now works in all modes.
+Thanks to Mogens Larsen for reporting the bug.
+
+* Added gnuchess.dat to the distribution and a couple of text files that were
+missing in 4.0.7.
+
+*** Merged in the following changes from Tim Mann:
+
+* Bugfix: Highlights would sometimes not be taken down, at least in
+xboard. The problem is that SetHighlight works in chess coordinates,
+not view coordinates, so if flipView has been toggled since the
+highlight was put up, it gets taken down from the wrong square. Fixed
+by being careful to call ClearHighlights before toggling flipView, not
+after. Ugh.
+
+* Bugfix: HighlightLastMove would sometimes highlight square a1 after
+a FICS "tomove black" command.
+
+* Bugfix: a move list with initial position that has black to play was
+not being handled correctly.
+
+* Removed "decline abort" and "decline adjourn" commands from Zippy.
+The syntax is changing on FICS, and Zippy really doesn't have to
+explicitly decline the requests anyway; it's sufficient to not accept
+them.
+
+* ICC wild 26 is now recognized as VariantSuicide (the FICS name; ICC
+calls it "giveaway").
+
+* Bugfix: PGN games with black to move in the initial position weren't
+being legality checked correctly. I think this was introduced in
+4.0.6 when I fixed a different PGN bug. Thanks to Mark Williams for
+spotting the bug and suggesting a fix.
+
+* Bugfix: the initial "name(" of a kibitz wasn't being colorized.
+
+Winboard Plus 4.0.7 -- Thu May 12 17:57 PDT 2000
+Mark Williams
+
+* New white pieces with black borders.
+
+* Major overhaul to Options menu. New dialogs for setting General Options,
+ Board Options, ICS Options, Sounds, Fonts, Colors.
+
+* Clipboard support for PGN game scores and FEN positions.
+
+* Optional ICS Premove with user-specified first moves for White and Black.
+
+* New sound events: ICS Win, ICS Loss, ICS Draw, ICS Unfinished, ICS Alarm.
+
+* New auto-flip option when playing against a chess program.
+
+* Added PGN Training mode.
+
+* Certain menu options now disabled while program is thinking.
+
+* ">>" button now always goes to the end of the game.
+
+* In ICS mode, the board is automatically activated at the start of a
+new game.
+
+4.0.7 -- Sun Mar 5 17:17:49 PST 2000 Tim Mann
+
+* Fixed a nasty bug in parsing ICS game histories that was introduced
+in 4.0.6.
+
+4.0.6 -- Fri Mar 3 16:20:11 PST 2000 Tim Mann
+
+* Fixed bugs in Zippy's code for responding to messages sent with the
+ICS "message" command.
+
+* Fixed bugs where xboard could still create dialogs partially off the
+top of the screen. Fixed unwanted interactions between initial sizes
+and positions of various unrelated xboard dialogs. Deleted
+borderXoffset and borderYoffset resources.
+
+* Fixed restoring the xterm name on exit to work in more cases.
+
+* Small fix to the WinBoard self-extracting installer: when it starts
+up, it now always deletes any old wb-setup directory left over from a
+previous installation. Formerly this worked only on Windows 95/98, so
+on NT the self-extractor would sometimes stop and ask the user whether
+it was OK to overwrite the old wb-setup files.
+
+* Modified WinBoard to be compilable with the free Cygwin tools
+available from http://sourceware.cygnus.com/cygwin/. Based on work by
+Mark Schoenberg. (His mods were enough to get WinBoard through the
+compiler, but a few things were broken along the way, so I reworked them.)
+
+* Merged changes from Don Fong to make WinBoard compilable with
+Borland C++ 4.5. I do not have Borland C++ and am unable to test with
+it, but I did make sure the changes don't stop it working with MSVC++
+5.0 and Cygwin.
+
+* Forbade entering TwoMachines mode from MachineWhite or MachineBlack
+mode when machine is on move. This used to confuse the engine and
+cause problems, because when we try to get the engine to stop, it
+might make a move first, and it might not do that immediately.
+
+* Variant classification now deals with new ICC wild 25, classifying
+it as "3check". Also, we are now conservative about new wild numbers
+we don't know about, classifying them as "unknown" instead of
+"normal".
+
+* Replaced bad GNU Chess 5.00 book in WinBoard distribution with a
+correct one. 1.e4 now no longer takes GNU Chess 5.00 out of book!
+Thanks to Pete Galati.
+
+* Made move parser accept and ignore nonstandard ep suffix on PGN moves,
+e.g., "exf6ep" or "exf6e.p."
+
+* Fixed bugs in parsing PGN files starting with no move number, or
+with a move number other than "1." (including "1..."). Thanks to
+Michael Soulier and Stefan Zipproth for example PGN files
+demonstrating the bugs.
+
+* Changed InitComboStringsFromString to not modify the input string;
+this caused an exception when WinBoard was compiled with MSVC++ 6.
+Thanks to Bert Tuyt for the report.
+
+* In WinBoard, dragging a piece off the edge of the board without
+releasing the mouse button no longer instantly aborts the move. You
+still must release the mouse button inside a square to complete a
+move, but you can now drag off the edge and come back inside.
+
+* WinBoard bugfix: If you went into EditGame or EditPosition mode
+while observing or playing an ICS game, and a new move came in
+(snapping you back to ICSClient mode) while you were dragging a piece
+around, the drag state would not be reset, causing the piece you were
+dragging to remain on the board wherever you dropped it. Thanks to
+David Brinegar for the bug report.
+
+* WinBoard bugfix: If you moved or resized the board while your
+opponent was moving, and you had AnimateMoving on, his move would not
+be displayed until after your next move. Thanks to DAV for reporting
+the bug repeatedly until I finally understood it.
+
+* Added a Zippy "farewell" feature; see zippy.README.
+
+* Fixed a bug (xboard only) in processing -zippyReplayTimeout on the
+command line. Thanks to Steve Beer for the report and patch.
+
+* Send "computer" command to both sides in TwoMachines matches.
+
+* Fixed a Y2K bug in Evan's cmail code! Thanks to Brian Mays for the
+report and patch.
+
+* Bugfix: Initialize variant field of GameInfo struct in gameinfo.c.
+This could cause crashes in LoadGame. Thanks to Andrzej Nagorko.
+
+* Fixed several pattern matching problems: Finger notes and formula
+vars no longer get replied to by zippyTalk or colorized. Channel
+tells by players with many titles are now colorized fully, and
+zippyTalk handles channel tells by such players correctly. The shout
+"--> foo(99): bar" no longer gets colorized as a channel tell. Code
+is cleaned up a bit, and autocomment capture now uses the same
+criteria as colorization.
+
+* xboard fix: Enter key now closes error popups as in WinBoard.
+Especially nice for the "Exiting: Connection closed by ICS" popup.
+
+4.0.5 -- Tue Dec 7 10:30:40 PST 1999 Tim Mann
+
+* Added missing documentation of SIGTERM usage into engine-intf.html.
+
+* Bugfix: New -zippyReplayTimeout option was misspelled in WinBoard as
+-zippyReplyTimeout. Thanks to Francesco Di Tolla.
+
+* xboard -ics now restores the xterm's original title upon exit, at
+least if $WINDOWID is set.
+
+* Bugfix: -matchGames mode wasn't terminating properly. Final score
+popup would come up twice and engines would not be killed off. Thanks
+to Frank Quisinsky for the bug report. Bug was introduced in 4.0.4.
+
+* Bugfix: "tell 50 foo shouts: bar" no longer gets colored as a shout;
+similarly for "...s-shouts:" and "...c-shouts:". Thanks to David Lee
+for the bug report.
+
+4.0.4 -- Fri Dec 3 17:51:27 PST 1999 Tim Mann
+
+* Bug fix: formerly if you invoked SaveGame from EditPosition mode
+with black to play, the position was not saved properly. As a quick
+fix, SaveGame now takes you out of EditPosition mode before saving.
+
+* Changed -matchGames to keep track of the score (won-lost-drawn) and
+display it in the banner. The final score is displayed in a modal
+popup before the program exits.
+
+* Changed "Connection closed by ICS" to display in a model popup
+before the program exits.
+
+* Added -popupExitMessage option, default on. Setting this to false
+suppresses the modal popups that you sometimes get just before
+xboard/winboard exits -- both the two new ones listed above and the
+existing Fatal Error popup. This is useful when running Zippy
+unattended from a shell script (or .bat file) that loops and starts a
+new copy after a time delay when there is an error.
+
+* In xboard, added missing support for WM_DELETE_WINDOW to all
+windows. This makes xboard a better citizen, and is much needed with
+the newer X window managers that put an [X] button on every window and
+bind it to "kill application" if the applicationd does not support
+"delete window". We can't allow xboard to be thoughtlessly killed,
+since that leaves the chess engine running in the background.
+
+* We now avoid positioning tops of xboard dialog boxes offscreen.
+
+* zippy.lines can now use the caret ('^') character as an inter-saying
+separator. You no longer need to dig up a text editor that can put NUL
+('\000') characters in text files.
+
+* Bugfix: In traditional chess clock mode, White now gets time added
+to its clock as soon as it makes time control. Previously both White
+and Black got their time added only when Black made time control,
+which would cause some engines to make their 41st move as White too
+quickly, thinking they were low on time.
+
+* The zippyAcceptOnly feature no longer sends a decline command or
+a tell. Thus you can use it to put Zippy into a manual accept mode.
+
+* Bugfix: "tell 50 foo tells you: bar" no longer gets colored as a
+personal tell; similarly for "...whispers:" and "...kibitzes:".
+
+* WinBoard no longer blanks the message line when you start a new
+move, unless there was an error message there from the previous move.
+
+* WinBoard now never puts the white piece drop menu on the middle
+mouse button. Both colors are always on the right button. Windows
+users often don't think to look for a middle button menu, or don't
+really have a working middle button despite what Windows says.
+
+* Guest login handles on ICC are now parsed again; an ICC wording
+change had broken this feature.
+
+* Autodetect when the engine does not support the "draw" command and
+don't relay the command to it in that case. Needed because sending an
+unsupported command to GNU Chess makes it move immediately, so people
+could make Zippy move without thinking by continually offering a draw.
+Thanks to Frank Walker for the problem report.
+
+* Small changes based on code from Robert Jurjevic: The WinBoard
+analysis window can be minimized (though not to the taskbar). The
+WinBoard ICS Interaction window will autoscroll if you drag the mouse
+above or below the window while selecting, and password entry mode
+leaves the entry line as the background color instead of using 75%
+gray. Seeks are now colorized with a new color of their own.
+
+* Added -zippyMaxGames feature.
+
+* -zippyNoplayCrafty command line option was missing in xboard; fixed.
+Thanks to John Perry.
+
+* Fixed bug in detecting when Zippy loses his bughouse partner.
+Thanks to Ben Dean-Kawamura.
+
+* allobs fix in 4.0.3 didn't work; corrected it.
+
+* WinBoard will now update the board immediately if a move is made
+while the window is being moved or resized.
+
+4.0.3 -- Sun Aug 15 18:44:39 PDT 1999 Tim Mann
+
+* Bugfix: moved winboard wizard functions that send a command directly
+to the chess engine from Ctrl+Alt+1 and Ctrl+Alt+2 to Alt+1 and Alt+2.
+Ctrl+Alt is equivalent to the European AltGr key, so the old assignments
+conflicted with typing an @-sign on some keyboards.
+
+* Bugfix: prevent "If this message stays up, your chess program does
+not support analysis" from appearing if AnalysisMode is selected when
+already in Analysis or AnalyzeFile mode. Also, deleting analysis window
+in WinBoard now switches you to EditGame mode, to avoid the anomaly of
+being in an analysis mode with no analysis window present.
+
+* Change all Zippy environment variables to work as command line
+options. For now they still work as environment variables too, but
+the environment variables are deprecated.
+
+* Use unsigned long to hold node counts from engines.
+
+* Print error instead of crashing on attempts to use xpm or xim pieces
+in monochrome mode. Thanks to Jim Torrance for the bug report.
+
+* Tightened pattern recognition for ICS messages sent to Zippy; should
+no longer match ICC allobs output. Fixed recognition of when Zippy is
+sent a message; small change to FICS output had broken it.
+
+* Zippy now exits if the engine dies unexpectedly.
+
+* Added Zippy "spoofedby" feature; see zippy.README.
+
+* Narrowed the margins on some older WinBoard dialogs to make their
+style uniform with the newer ones.
+
+* Bugfix: Changing Ponder Next Move from the Options menu did not take
+effect until the next game. This bug was in WinBoard only. Thanks to
+Stefan Zipproth for the bug report.
+
+* Got rid of "Internal error: bad move type" message when the engine
+makes a move that we can parse but think is illegal. Now the move is
+just passed on (which also may be the wrong thing to do).
+
+4.0.2 -- Thu Feb 25 19:55:32 PST 1999 Tim Mann
+
+* Added one more built-in sound choice to WinBoard: move.wav from Pete
+Galati.
+
+* Added new larger piece sizes: big, huge, giant, colossal, titanic.
+
+* Modified the xboard font searcher to be able to use scalable fonts.
+The new -fontSizeTolerance flag controls how closely a nonscalable
+font must match to be used in preference to a scalable font.
+
+* Zippy environment variables ZIPPYABORT and ZIPPYADJOURN now control
+whether Zippy will accept abort and adjourn requests.
+
+* We now determine the variant type being played on ICS, send it as a
+command "variant VARTYPE" to the chess engine (if in Zippy mode), and
+put it in the PGN tags. See engine-intf.txt for variant names. See
+ZIPPYVARIANTS in zippy.README to control what variants Zippy will
+accept. Note that this now applies to bughouse, too.
+
+* Zippy now won't do -zippyTalk in a channel unless his handle is
+mentioned there.
+
+* Zippy now ignores bughouse holdings if not actually playing, instead
+of stupidly trying to abort the game. Let me know if other strange
+things happen when Zippy is observing a game.
+
+* Set ICS Interaction title bar to "user@server". User name is
+determined by parsing message during the login sequence. Zippy now
+uses this method to get its name too, so ZIPPYNAME is eliminated.
+Problem: with xboard, the title bar gets set to "xterm" upon exit,
+since we didn't know what it was to start with.
+
+* Fixed xboard-only bug in -colorChannel1 command line option. Thanks
+to Fredrik Sandstrom for the bug report and fix.
+
+* Check for overflow of MAX_MOVES. Still not sure this is checked for
+everywhere it needs to be.
+
+* Added .epd to suffixes recognized by WinBoard as position files.
+This is a bit of a kludge, as the .fen reading code was not written
+with .epd files in mind, but reading them with it is said to work.
+
+* Added ZIPPYGAMESTART feature, suggested by Jason Hoblit. See
+zippy.README.
+
+* Restored the feature of soaking up the moves from a user-typed "moves",
+"oldmoves", or "smoves" ICS command when xboard/WinBoard is idle, but
+changed it so that the move list is also echoed to the screen. Some folks
+still liked the old feature since it is faster than examine mode, and
+printing the moves to the screen should eliminate the confusion it caused
+for other people.
+
+* Bugfix: in WinBoard, starting a click-click move and then clicking on
+a black line would cause the source square to be forgotten without taking
+the highlight down. Now the errant click is ignored.
+
+* Corrected shortcut key labels for LoadNext/PrevPosition in WinBoard's
+File menu. Thanks to Andreas Stabel for the bug report.
+
+* Bugfix: if you had a completely full ICS context menu in WinBoard
+(90 items), the last one would do nothing if selected.
+
+* The "computer" engine command added in 4.0.1 was not working; I had
+left out part of the code patch. Oops.
+
+4.0.1 -- Fri Feb 12 21:24:15 PST 1999 Tim Mann
+
+This is a minor bugfix release. The first item listed below is the
+only interesting new feature.
+
+* You can now type in moves from the keyboard in WinBoard. Either
+select TypeInMove from Step menu, or (if you are not in ICS mode),
+just start typing. In ICS mode you can type moves into the ICS
+interaction window anyway, so I've retained the feature that typing
+switches you there. Not implemented in xboard.
+
+* Removed the "noise 1000" command that used to be sent to the chess
+engine when entering analysis modes.
+
+* Deleted the feature where we soak up the output of a user-typed ICS
+"moves" or "oldmoves" command. This ancient feature is not really
+useful anymore, now that "examine" exists, and it caused a lot of
+complaints.
+
+* Increased maximum size of ICS text menu to 90 entries and added
+overflow checking.
+
+* The command sent to ICS by Zippy at the end of each game can now be
+customized with the ZIPPYGAMEEND environment variable.
+
+* We treat xboard.info as a pseudo-source since most people don't have
+the tools to rebuild it. But "make install" erroneously had a
+dependency on it, even though "make all" did not. Fixed.
+
+* Miscellaneous minor updates and clarifications to engine-intf.txt.
+In particular, documented the st and sd commands (support for command
+line options -searchTime and -searchDepth), warts and all.
+
+* Added a small code patch from Bob Hyatt to detect when Zippy's ICS
+opponent is a computer and send the command "computer" to the engine.
+Added this command to engine-intf.txt. Thanks, Bob.
+
+* Bugfix: configure was looking for usleep(), but config.h.in didn't
+have an entry for it, so HAVE_USLEEP was never defined. Also, in the
+non-HAVE_USLEEP case, there was a possible race condition between the
+signal handler and the pause() call. Thanks to Ben Dean-Kawamura for
+the bug reports.
+
+* Bugfix: a "1..." preceding Black's first move (usually present if
+there is a comment on White's first move) would cause the parser
+to think a new game started there and report "End of game" on the
+current game. Thanks to Dell Garner for the bug report.
+
+* Changed the abbreviation for -searchDepth from -sd to -depth to fix
+a clash with -secondDirectory.
+
+* Changed -searchDepth to be orthogonal to the various timing options.
+Previously it would search for an unlimited time to the given depth;
+now the engine is allowed to choose its search time in the normal way,
+but is told to cut off the search early if it reaches the given depth.
+
+* Bugfix: SaveSettings in WinBoard was saving both the long form
+option highlightSquareColor and its abbreviation (hsc).
+
+* Fixed a redisplay bug in DisplayBothClocks that could cause White's
+clock to be highlighted in EditPosition mode when Black's should have been.
+
+* Fixed Zippy's feature of passing on draw offers from the ICS opponent.
+The colorization code was eating the offer before Zippy saw it, so I disabled
+colorization of offers while in -zp or -zt mode. (Other types of
+colorization are already disabled in Zippy mode for similar reasons.)
+
+* Added some more commands to the default ICS context menu in WinBoard,
+and put "(name)" on the ones that insert a playername (or game number).
+
+* Added missing documentation to WinBoard help file: PonderNextMove, the
+-ponder/-xponder argument, and the up/down arrow history feature in the
+ICS Interaction window.
+
+* Fixed ZIPPYNOPLAYCRAFTY feature to fire only if the opponent is Crafty,
+not if some other Crafty is observing the game and kibitzes.
+
+* Fixed bugs in generating "partner" commands when Zippy is playing
+bughouse.
+
+4.0.0 -- Sat Jun 20 16:59:47 PDT 1998 Tim Mann
+
+* Fixed WinBoard resizing so that the edges you do not drag remain in
+place, even when the final size is different from what you dragged to.
+(This doesn't work on NT 3.51 or earlier, if anyone cares.)
+
+* Fixed problems with resizing WinBoard on Windows NT: you no longer get
+whitespace around the board, a clipped board, or a lot of flashing during
+the drag.
+
+* Added customization for highlight-square color.
+
+* Bugfix: backend.c wrote to stderr in a few obscure places, which doesn't
+work in WinBoard.
+
+* Added Index Number field back to LoadGame/LoadPosition dialog boxes in
+WinBoard. This required some extra code to work with both the
+Explorer-style dialog boxes and the old-style NT 3.51 dialog boxes. Ugh.
+
+* WinBoard startup dialog now understands -zp mode. The first chess
+engine selector is enabled and the value is used.
+
+* Bugfix: ResetGame would send "exit" to engine twice if it was in an
+analysis mode.
+
+* Bugfix: The response "Illegal move: bk" to the "bk" command, indicating
+that it is not implemented, would confuse xboard.
+
+* Bugfix: Ignore empty hints ("Hint:\n") instead of printing a message
+saying that some bogus string (often "Hint:") is illegal.
+
+* Bugfix: LoadNextGame/LoadPreviousGame/ReloadSameGame were broken.
+
+3.6.12 -- Sat Jun 13 14:57:10 PDT 1998 Tim Mann
+
+Beta test release of xboard and WinBoard.
+
+* Spruced up xboard man page a bit.
+
+* Added Highlight Last Move to xboard too.
+
+* The revamped xboard mouse click code had several more bugs than the
+previous version, so I revamped it again. All fixed now, I hope.
+
+* xboard bugfix: crash in CreatePieceMenu.
+
+* Oops. winboard-3_6_11beta.exe installed 3.6.10beta, not the new version.
+
+3.6.11 -- Fri Jun 12 20:00:48 PDT 1998 Tim Mann
+
+Beta test release of xboard and WinBoard.
+
+* Major reorganization to engine-intf.txt. Some new features added,
+many existing features clarified and hints for engine programmers added.
+Support for new features added to program.
+
+* Changed defaults for -scp (etc.) back to being independent of -fcp, as
+in 3.6.2. That is, the default is no longer to copy the value from -fcp if
+-scp is not specified. This will sometimes make command lines longer but
+will remove some confusing situations.
+
+* Split -reuseChessPrograms into two options: -reuseFirst and
+-reuseSecond. Fixed obscure bugs when reuse is off.
+
+* Detect ICC and change some command usage slightly there: only ICC has
+set-quietly; only FICS has iset and bsetup clear. With this feature, we
+can now safely use bsetup clear when appropriate instead of deleting each
+piece one by one.
+
+* Added indent to lines that are wrapped by WinBoard ICS Interaction
+window. This seems to tickle a Microsoft bug in the RichEdit control:
+occasionally the start of the next line after the wrapped line is indented
+too. I think the wrapped indent feature is useful enough that it's worth
+having in spite of the bug.
+
+* WinBoard bugfix: bounding box for the board was computed incorrectly by
+mouse code. It would think you moved off the bottom of the board before
+you really did, so it was hard to drag pieces along the bottom rank on
+smaller board sizes.
+
+* Fixed obscure parser.l bug: ambiguity between capture using : instead of
+x and email header line. Also removed or simplified a lot of complex
+patterns for English (as opposed to PGN) end-of-game indications while I
+was in there.
+
+* Added PonderNextMove option.
+
+* xboard EditPosition piece menus now let you set the side to play by
+selecting the "White" or "Black" label at the top of the menu, like
+WinBoard. (Both xboard and WinBoard still let you set the side to play by
+clicking on the clock.)
+
+* Merged documentation of Crafty and GNU Chess thinking output in
+engine-intf.txt. Corrected code in backend.c to match documentation; it
+used to require the PV to start in column 27 (!).
+
+* Fixed bug that caused crashes in "-reuseChessProgram false" mode.
+
+* Draw by agreement in Two Machines mode now works as it is supposed to.
+Other minor bugs in handling game end messages from machines are also
+fixed, and engine-intf.txt is revised in this area.
+
+* Revamped xboard code for handling mouse clicks on the board. In
+particular, it had a bug if a click-click promotion move was made.
+
+* Fixed and reinstated optimization for << in analysis modes: send
+initString and re-send the board if needed. Sending repeated undos
+is bad because Crafty prints some analysis after every one.
+
+* Don't go into a spin loop while pausing between xboard animation frames.
+This caused problems, especially when compiling with -O2 on HP-UX.
+
+* WinBoard Options/Colors/RevertToDefaults now also turns off Monochrome
+if it was on, and similarly for Options/ICSInteractionColors/RevertToDefaults.
+This seemed to confuse people before.
+
+* Bugfix: ICS Interaction context menu items with neither of the two
+optional flags set did not work.
+
+* Bugfix: PGN move numbers are optional, but we were insisting on "1"
+right after the tags.
+
+* Bugfix: only the first game of an -mg match was loading -lpf or -lgf.
+
+* Other minor fixes and code cleanup.
+
+3.6.10 -- Mon Jun 1 01:32:31 PDT 1998 Tim Mann
+
+* Added ZIPPYNOPLAYCRAFTY feature; see zippy.README.
+
+* Added timestamps for chess engine interaction to -debug output.
+
+* Now allow 10 seconds (was 5) between games in match mode for engines to
+respond to "force" command that ended previous game.
+
+* When a game is picked from the game list and the names of White and
+Black are known, display them in the window banner instead of the filename
+and game number.
+
+* Changed default for -scp and -sd to be the values of -fcp and -fd.
+
+* Added boxes for both engines to WinBoard startup dialog. Changed to
+dropdown boxes whose content can be set from winboard.ini, similar to
+the box for ICS name.
+
+* Accept "offer draw" (or "*offer*draw*") from engine to offer a draw.
+
+* Accept "move mmmm" from engine as well as silly "1. ... mmmm" syntax.
+
+* Added support for bughouse engines (Zippy mode only).
+
+* Move bombproofing for engines sending illegal or out of turn moves.
+
+* Always send "xboard\n" to engine as first command. Eliminates need
+to run crafty as "crafty xboard".
+
+* Rewrote xboard code for input from engines to fix longstanding bugs.
+Previously an engine that sent one line in two separate writes with
+some time lapse in between (or perhaps that sent several lines in one
+write) could make xboard hang. WinBoard did not have this bug.
+
+* Fixed minor bugs in dealing with illegal moves.
+
+* Added "iset startpos 1" for FICS.
+
+* Removed special support to put "GNU Chess" or "Crafty" in the window
+banner instead of the engine's base filename. This gives a more level
+playing field for other engines. Also fixed bugs in the code that finds the
+engine's base filename.
+
+* Bugfix: Abort or Resign at the very start of a game in chess engine mode
+would fail to send "force" to the engine.
+
+* Fixed some minor bugs in new "result" messages, and changed format to
+include a trailing PGN comment giving the reason the game ended.
+
+* Changed syntax of /font options in WinBoard; old syntax was assuming
+that a font name can't contain a digit, which is wrong. Old font names in
+WinBoard.ini files are still accepted.
+
+* Serious further work on getting WinBoard to read/write files in the
+"right" directories and documenting exactly what it does.
+
+* Added LoadPreviousPosition, LoadNextPosition, ReloadSamePosition.
+
+* Misc. tiny fixes and cleanup.
+
+3.6.9 -- Sun May 24 20:53:08 PDT 1998 Tim Mann
+
+xboard and WinBoard beta release.
+
+* Tightened up illegal move handling. Illegal or meaningless moves from a
+file or chess engine should no longer get translated into a1a1 and blindly
+applied. Explicit moves to the same square (like a1a1) no longer make the
+piece on that square capture itself and vanish.
+
+* Added AlwaysOnTop feature to winboard.
+
+* Fixed bug in winboard "@" command line indirection operator.
+
+* Removed buggy "optimization" code for ToStart in analysis modes.
+
+* Fixed typo bug in zippy.c that would often cause winboard to crash
+right after starting a game in -zp mode.
+
+3.6.8 -- Sat May 23 22:23:19 PDT 1998 Tim Mann
+
+xboard and WinBoard beta release.
+
+* Added -firstDirectory and -secondDirectory so that chess engines can
+be started in a different directory from xboard/WinBoard itself.
+
+* Added -matchGames to allow more than one game in -matchMode. The games
+are played with colors alternating between the two chess engines. Had to
+add a time delay at the end of each game to catch up with game ending
+messages from both chess engines -- yuck.
+
+* Changed TwoMachines mode to have firstChessProgram play White by
+default. Added -firstPlaysBlack to restore old behavior.
+
+* Major rework of code in backend.c for dealing with first and second
+chess engines. Generalized the code and created a struct type with one
+instance for each engine. Several small bugs fixed along the way.
+
+* Fixed bugs in Abort in local chess engine mode.
+
+* Tightened pattern matching to recognize moves from machine. Should cure
+bogus "Illegal move" errors while Crafty is pondering with Show Thinking
+on, among other things.
+
+* WinBoard keeps focus in board window after popping up a comment due to
+Forward/Backward/ToStart/ToEnd commands.
+
+* Finally got rid of warnings on compiling moves.c under Windows.
+
+* Fixed so WinBoard will compile on machines where WM_MOUSELEAVE is not
+defined.
+
+* Removed various bits of unused code.
+
+* Parse (and ignore) NAGs in PGN files.
+
+* Updated engine-intf.txt.
+
+* Send "result R" to the chess program at the end of each game, where
+R is the PGN result 1-0, 0-1, 1/2-1/2, or *.
+
+* Bugfix: suppress animation when loading a game with timeDelay=0.
+
+* Bug fix: pondering output from Crafty that contained "..." could be
+mistaken for a move, causing bogus error messages and general chaos.
+
+* xboard "make clean" bug fix: moved things created by configure to be
+removed only by "make distclean".
+
+* Fixed a remaining case where move was being animated before being
+relayed to opponent.
+
+* Backend was reversing time/otim commands to the chess program (new bug),
+and was often not sending them on the first move of a game or the first
+move after a mode change (old bug). Fixing the latter required a kludge
+to work with both GNU Chess and Crafty, because Crafty swaps white and
+black clock times when it swaps sides, while GNU Chess does not. The
+kludge is that we always make sure the chess engine thinks its opponent is
+on move before we set the clock. This will sometimes result in sequences
+like "white\ntime xxx\notim yyy\nblack\ngo", or the same with white and
+black interchanged.
+
+* Removed last trace of old -whiteString and -blackString arguments.
+
+* Fixed so that you can type "bd" into the Direct Command dialog when
+debugging gnuchess, without having xboard parse the clock display
+(starting with "White") as "White wins" and end the game.
+
+* Changed moves.c to make a distinction between IllegalMove (where we
+could tell what move was intended, but it violates the chess rules) and
+MeaninglessMove (where we could not tell). This is a step towards getting
+rid of cases where we translate meaningless moves into "a1a1", but some
+work is probably needed to track them all down.
+
+* Fixed bug in WinBoard monoMode dragging.
+
+* Changed WinBoard to new style file dialogs. In the process, disabled
+the feature that let you enter the index number of a game or position within
+the file in the dialog. This is no loss in LoadGame, as you can pick your
+game from the game list dialog that follows, but it does remove some
+functionality from LoadPosition.
+
+3.6.7 -- Mon May 18 21:25:00 PDT 1998 Tim Mann
+
+xboard and WinBoard beta test release. I've been unable to reproduce some
+reported drawing bugs, so they may still not be fixed.
+
+* Changed PopUpErrors option to PopupMoveErrors, which is more useful, and
+changed default to off. Errors other than move errors should always be in
+popups; they are often too big for the message area and too important to
+put where they can be easily missed. But it seems good to get rid of the
+popups for move errors by default.
+
+* xboard analysis window no longer forces itself to top whenever there is
+new output. Also, now uses built-in Xaw word wrapping instead of trying
+to do its own; works better.
+
+* Bugfix: Reset did not take Crafty out of analyze mode.
+
+* A chess engine no longer has to claim to be Crafty to be able to use
+AnalysisMode and AnalyzeFile; it just has to implement the analyze
+command as Crafty does. Put in heuristics to generate more informative
+error messages if the engine does not support analyze, and checked that
+they work at least with GNU Chess.
+
+* Added click-click moving, HighlightLastMove, and HighlightDragging to
+WinBoard. The highlight features are unlikely to go into xboard unless
+the xboard drawing code is cleaned up to do *all* drawing on the board
+from DrawPosition, as WinBoard does. This is low priority for me.
+
+* Eliminated bogus "Error gathering move list: no header" popup. You
+could get this by observing two fast games at once without turning off
+GetMoveList.
+
+* Disable WinBoard Sounds menu entirely in -ncp mode, since not even
+MoveSound is used in that mode.
+
+* WinBoard bugfix: Several problems were caused if the user changed
+WinBoard's current directory in a Load, Save, or Browse dialog. In
+particular, WinBoard.ini would get saved in the wrong directory, and
+sound .wav file names would not get saved with a full pathname. I think
+all such problems are now fixed.
+
+* WinBoard bugfix: iconizing the board after an aborted mouse resize would
+(partially) resize it to Tiny.
+
+* WinBoard bugfix: board was not being drawn in color on 256-color
+displays. This bug was introduced in 3.6.6.
+
+3.6.6 -- Tue May 12 17:43:43 PDT 1998 Tim Mann
+
+xboard and WinBoard beta release. Note: not all reported bugs are fixed.
+
+* Move animation in WinBoard, programmed by Henrik Gram. Great stuff!
+
+* Animate backward moves too.
+
+* xboard bugfix: -font (and friends) can now specify a font alias (such
+as "fixed"), not just a full X Consortium name pattern. Previously this
+would give a resource conversion error message.
+
+* Some coding style cleanup in xboard.c.
+
+* Earlier error check for moving wrong color piece in EditGame mode.
+
+* Completed fix to pattern matching; see 3.6.5.
+
+* Fixed some software rot bugs in Zippy.
+
+* Split AnimateDragging as separate option from AnimateMoves.
+
+* Added FlashMoves to options menu and -flash/-xflash to command line
+options (xboard only).
+
+* Some preliminary work on visible bughouse holding support. Most of the
+code is not present in this release because I have not gotten it working
+properly yet; my first approach went down a blind alley and I had to
+remove most of the partially working code in preparation for a rewrite.
+
+3.6.5 -- Fri May 8 14:22:09 PDT 1998 Tim Mann
+
+Not generally released.
+
+* Pack bughouse holdings display in banner more tightly when board is one
+of the smaller sizes (when smallLayout or tinyLayout is true, that is).
+An interim measure, but should help.
+
+* Completed fix to make move list parsing recognize the end condition and
+final comment.
+
+* Fixed pattern matching for chatter (tells, etc.) to be more reliable.
+This should reduce the incidence of colors starting in the wrong place and
+of incorrectly matching things that look like other patterns inside
+chatter, such as "shout <12>". (These errors were already rare.)
+
+* WinBoard now lets you customize the list of ICS's in the startup dialog.
+For now, at least, requires editing WinBoard.ini with a text editor.
+
+* Bug fix: WinBoard window sizing and position setting save/restore did
+not work right when the taskbar was at the top (or left side) of the
+screen and not in autohide mode.
+
+* Merged xboard click/click mode and drag mode, and deleted
+ClickClickMoving option on menu. Now if you click on a piece, it
+highlights and a further click on another square will move it. (A second
+click on the same square takes down the highlight.) Or if you press down
+on a piece and start to drag, you can drag it to a new square.
+
+* When making click/click style moves, if your second click is on a piece
+of the same color, instead of saying "Illegal move", we now cancel the first
+starting square, replace it with the second, and wait for another click to
+finish the move.
+
+* Separate -secondInitString. Default: same as -initString. Suggested by
+Remi Coulom.
+
+* Patch from Frank McIngvale to make animation work with XIMs. Yay!
+
+* Changed move animation to happen after move is passed on to ICS or the
+chess engine, where applicable. Fixed problems with updating moveList
+that this uncovered.
+
+* Changed game list to show PGN result token for each game.
+
+* The usual minor bug fixes.
+
+3.6.4 -- Thu Apr 30 23:14:43 PDT 1998 Tim Mann
+
+xboard and WinBoard beta test release.
+
+* xboard documentation updated, both man page and info file. An attempt
+to generate both from the same source with LinuxDocSGML was abandoned, at
+least for now. WinBoard doc updated too.
+
+* Merged updates to animation code from Hugh. Fixed a couple of remaining
+bugs, mostly to do with handling Pause mode correctly.
+
+* Added SaveSettingsOnExit to WinBoard.
+
+* WinBoard now saves the last screen position of the Comment, Edit Tags,
+Game List, and Analysis windows (in addition to the board and ICS
+Interaction windows) in WinBoard.ini.
+
+* WinBoard now provides a way to customize the right-button context menu
+in the output area of the ICS Interaction window. For now, requires
+editing WinBoard.ini with a text editor.
+
+* Various minor fixes to ICS message recognition, most affecting only Zippy.
+
+* Colorize the notification when someone sends you a message while you are
+logged in, not the output of the "messages" command.
+
+* Fixed colorization to turn off at the right place more reliably.
+
+* Added a new color and WinBoard sound for "requests": abort, adjourn,
+draw, pause, and takeback. The same color and sound are used for all of
+these.
+
+* Added GUI to change sounds in WinBoard.
+
+* Suppressed WinBoard error popup when a sound can't be played. They were
+popping up when two separate WinBoards tried to play a sound at the same
+time (such as during a bughouse match).
+
+* Fixed WinBoard crash when a sound file didn't exist.
+
+* WinBoard ports of timestamp and timeseal now produce decent error
+messages if they fail to connect, and WinBoard captures the messages and
+puts them into a popup. Previously WinBoard would exit with no message on
+such errors.
+
+* WinBoard resizing with mouse improved; now accurately picks the largest
+size that fits in the new area.
+
+* Added option to turn off error message popups.
+
+* Added sizes slim, dinky, and teeny.
+
+* Fixed some minor problems with error message wording.
+
+3.6.3 -- Mon Feb 23 19:08:57 PST 1998 Tim Mann
+
+xboard beta test release only. Man page is updated for the changes, but info
+file is not.
+
+* Bug fix: LoadGame could not load a PGN game whose first move was
+castling (which is possible from setup positions).
+
+* Bug fix: we were ignoring illegal move messages from chess engines in
+modes where the engine is refereeing but not participating (EditGame,
+LoadGame, AnalyzeFile). The problem was in a workaround for a Crafty bug,
+where Crafty generates a bogus illegal move message if a "." (used by
+the PeriodicUpdates feature) is sent in analysis mode when the current
+analysis reveals a forced mate. Installed a different workaround (that
+works in most but not all cases) and reported the Crafty bug. Bob Hyatt
+replied with a fix, so the Crafty bug should be gone in Crafty 14.12 or so.
+
+* WinBoard only: enabled resizing board with the mouse. It snaps to the
+nearest (but not too much larger) predefined size.
+
+* The xboard default font is now sized according to piece size, just as
+clockFont and coordFont have always been.
+
+* Added more sizes: bulky, moderate, average, middling, mediocre, petite.
+
+* xboard only: Added Animate Moves and Click-Click Moving to Options menu.
+
+* xboard only: Added code to animate piece movement, from Hugh Fisher.
+
+* New feature: autoflag is implemented in MachineWhite, MachineBlack, and
+TwoMachines modes. If it is on and either a chess program or the user
+oversteps his time, xboard will automatically call the flag and end the
+game. This feature was requested by someone who runs matches between
+programs and wants to penalize GNU Chess for its habit of running slightly
+over at the end of a time control. I personally think it's pointless.
+
+* Fixed a bug in Zippy's pattern matching; he can now reply to ICC
+messages again.
+
+* Generate prettier notation for illegal moves. If a move is illegal only
+because it leaves the player in check, generate notation as if that were
+not illegal. For instance, if two knights are a knight's move away from
+f3, one on g1 and one on e5 that is pinned, the notation would be Nf3 to
+move the g1 knight, Nef3 to move the e5 knight. (Suggested by Philippe
+Schnoebelen.) In addition, if a move is illegal because the type of piece
+moved cannot go that way, would be jumping over another piece, etc., we
+give fully disambiguated coordinate notation; for example, Ng1g3, Ke1xe8,
+d2xd8=Q, etc. An alternative would be to still write Ng3 if there is only
+one knight on the board, or Ngg3 if the other knight is not on the g file,
+but life is too short to code up all this stuff, and perhaps the way I did
+it is better as it emphasizes that this move was really made despite being
+illegal. I wonder if the new PGN standard revision will speak to notation
+of illegal moves?
+
+* Fixed gross bug from 3.6.2: if a chess program said "checkmate" and
+White was left on move, the PGN outcome was "1-0 {Black mates}" instead
+of "0-1 {Black mates}"! The bug occurred only for that specific string.
+
+3.6.2 -- Wed Jul 23 16:47:29 PDT 1997 Tim Mann
+
+* There was a bug in backing up from the end of a game against a chess
+engine, introduced when -reuse mode was added. Fixed.
+
+* Recognize "{" as terminating an ICS move list. Previously we needed to
+see a prompt (containing %), but occasionally ICC can send more stuff
+right after a move list with no prompt in between.
+
+* In WinBoard, -mm now implies -cp, so you don't get the startup dialog.
+
+* WinBoard startup dialog no longer sets -scp. People used to get
+confused because they would give the -fcp and -scp arguments, but omit
+-cp. This would bring up the startup dialog, which would set both -fcp
+and -scp to the value in the engine name box. Now you can change -scp
+only with the command-line argument. That will confuse some people too,
+but hopefully fewer. I think overall it's better than putting spaces for
+both -fcp and -scp in the dialog, which would puzzle newbies.
+
+* Bug fix: Analyze File mode now works in WinBoard.
+
+* Bug fix: WinBoard window no longer cuts off part of the bottom row if
+the menu bar wraps to a second line.
+
+* Accept game end messages of the form "PGN-result {comment}" from the
+chess engine, where PGN-result is 0-1, 1-0, or 1/2-1/2. Accept "resign"
+or "computer resigns" from the chess engine as a synonym for "0-1 {White
+resigns}" or "1-0 {Black resigns}". Accept any message from the chess
+engine containing "game is a draw" as a synonym for "1/2-1/2 {Draw}".
+Accept "White resigns" or "Black resigns".
+
+* Enable "Action / Draw" menu item in chess engine mode. It sends the
+command "draw" to the engine. Accept any message from the chess engine
+containing "offers a draw" as a draw offer. WARNING: Draw offers from the
+user and the engine (or from two engines) are not yet matched up by xboard
+in chess engine mode. Two engines could get into a loop offering each
+other draws.
+
+* Bug fix: Game end messages from the chess engine are always ignored in
+Zippy mode. Previously they could sometimes be processed, which was
+sometimes making Zippy hang at the start of a new game that followed
+quickly after an old one.
+
+* Zippy can now respond to titled players in channels. Zippy will avoid
+talking to himself in a channel if he knows his own name.
+
+* Bug fix: in colorization arguments, the bold setting was being ignored
+if the background color was defaulted. (xboard only.)
+
+* Extended ParseFEN to accept Crafty 12.2's interpretation of FEN.
+If fewer than 8 squares are given in a row, or fewer than 8 rows are
+given, the uncovered squares are empty. Also, there can be a / after the
+8th row.
+
+3.6.1 -- Sat May 17 01:02:33 PDT 1997 Tim Mann
+
+* Bug fix: Hitting escape while entering a password on WinBoard no longer
+sets the font color back to black (which made further typing visible).
+
+* Bug fix: On Windows NT 4.0, WinBoard /ics /icshelper=timestamp would
+often hang if you tried to exit with the Exit menu item, the [X] button,
+etc. The same fix may also have corrected the problem where running a
+chess program with /xreuse would sometimes crash Windows 95 (but not NT)
+when the chess program was killed and quickly restarted.
+
+* Bug fix: Periodic Updates would not work if turned on after having been
+off. Also, the default was needlessly "off" in WinBoard.
+
+* Zippy bug fix: Continuing an adjourned game was totally broken. The
+wrong moves, or no moves at all, were being fed to the chess program.
+
+* WinBoard change: Giving -ics without -icshost now pops up the startup
+dialog with "Use an Internet Chess Server" pre-selected, so that you get a
+menu of chess servers instead of going directly to ICC.
+
+* Bug fix: WinBoard's SaveSettings was saving -icshost, -icsport, and
+-icshelper in winboard.ini. This causes a problem if you use a different
+icshost later that needs the default values for icsport (5000) and
+icshelper ("", meaning none).
+
+* Disabled complaints about unexpected "[Ii]llegal move" messages from
+the chess program; we still get them at times.
+
+* Greatly simplified the code for Move Now and SIGINT (ATTENTION). Fixes
+the bug where Move Now did not work with GNU Chess in WinBoard, and
+several more obscure bugs as well. Reintroduces a minor bug: GNU Chess might
+not think on your time after a Move Now command. Trying to fix this
+causes too many other problems. Documented change in engine-intf.txt.
+
+* Cleaned up code for obtaining ratings from ICS. It was kludgey and may
+have had bugs on systems with no "Creating:" message. It should fail
+gracefully there, just not finding the ratings.
+
+3.6.0 -- Thu May 8 19:55:58 PDT 1997 Tim Mann
+
+* WinBoard now has right-button context menus in the ICS Interaction
+window. Some of the items do immediate commands on the player name you
+have selected or pointed to. (Suggested by Paolo Casaschi.) Also, the
+middle button or shift+right does a immediate Copy and Paste.
+
+* Fixed a bug in Zippy's wild rejection. The bug was causing Zippy to
+reject all forms of wild. Now it rejects only 1, 9, 16, 17, and 24, as
+was intended. These variants have different rules, while the other
+variants defined so far only have different starting positions.
+(Actually, wild 2, 3, and 4 never allow castling, but may sometimes by
+chance have king and rook start on squares where castling appears legal.
+This could cause a problem later.)
+
+* Zippy now resumes adjourned games by feeding the chess program
+the move list instead of the position. Setting -getMoveList to False
+restores the old behavior. Feeding in the move list is better because
+it enables the chess program to correctly handle en passant legality,
+castling legality, draw by repetition, and draw by the 50 move rule.
+
+* Added a WinBoard startup dialog for people who run WinBoard.exe without
+using the Start menu or reading the help file. Instead of being dumped
+directly into GNU Chess mode, you now get a menu of choices. You now have
+to give the new WinBoard -cp option to go directly into chess engine mode.
+I did not add this feature to xboard.
+
+* Handling of "illegal move" from Crafty is now back on. (It was turned
+off in 3.4.6; see below.) Crafty 12.0 doesn't seem to send bogus ones
+anymore. I did have to suppress sending time and otim in analyze mode to
+make this work, but there is no harm in that.
+
+* Zippy now sends "gameend" to ICS at the end of each game. You can alias
+this to "seek" or whatever you like.
+
+* Added Crafty support for Move Now, using the "?" command. We test
+whether this command exists by trying it once at the start of the first
+game, before it really makes sense. If we don't get a message like
+"Illegal move ... ?", we assume it's OK. (We're careful about this
+because sending a "?" to GNU Chess on Move Now keeps it from pondering the
+next move as it should.)
+
+* Added support for a tellusererror command from the chess engine. See
+engine-intf.txt.
+
+* Attempted to make engine-intf.txt complete.
+
+* Minor fixes/cleanup to GameEnds code, to be sure we always interrupt
+when needed, and always undo an extra move generated by stopping the chess
+program while it is thinking.
+
+3.5.7 -- Sat May 03 22:37:44 PDT 1997 Tim Mann
+
+Beta release of both xboard and WinBoard.
+
+* Updated xboard documentation. I really wish the man page was built from
+the info file instead of being separate! It's a pain to update them both.
+
+* Updated documentation of the interface between XBoard/WinBoard and chess
+programs, and renamed it to engine-intf.txt.
+
+* Added support for tellics, telluser, and askuser commands from the chess
+engine. See engine-intf.txt.
+
+* Various bug fixes. On WinBoard, 256 color displays are finally handled
+right; no more color flashing when you switch windows unless the colors
+really need to be updated. Also, I think the problem of the console font
+failing to change or changing back by itself is finally fixed.
+
+3.5.6 -- Tue Apr 29 03:08:00 PDT 1997
+
+Beta release, WinBoard only. ChangeLog was out of date in release,
+updated here.
+
+* Added ICC timestamp and FICS timeseal to WinBoard distribution. These
+are my own ports to Win32, based on and used by permission of the owners
+of the proprietary source code (Daniel Sleator for timestamp, Henrik Gram
+for timeseal). The owners permit these programs to be distributed only in
+binary form (to help prevent cheating), so to avoid running afoul of the
+GPL, I have kept them as separate programs, not linked into the WinBoard
+address space. Updated Start menu icons to use them.
+
+* Miscellaneous smaller changes.
+
+3.5.5 -- Fri Apr 25 03:06:00 PDT 1997
+
+Beta release, WinBoard only. ChangeLog was out of date in release;
+updated here.
+
+* Added simple sound support to WinBoard.
+
+* Updated WinBoard documentation.
+
+* Internal implementation of the telnet protocol is now more complete.
+You can now hop through a VMS host on the way to ICS. For example, do
+"xboard -ics -icshost vms.host.edu -icsport 23", then log in. Do not use
+the -telnet flag; that says to use an *external* telnet program. To avoid
+double echoes, you need to force character mode in VMS telnet after
+connecting from VMS to ICS. Do "^]^Mset mode char^M^M".
+
+* Display opponent names in the title bar for MachineWhite, MachineBlack,
+and TwoMachines modes.
+
+* WinBoard now has an installer, built with InstallShield. The installer
+works with a binary-only distribution. Sources are still freely
+available, but now separately.
+
+* Added SaveSettings to WinBoard, which saves current option settings to
+winboard.ini. Made sure all options can be saved and loaded, including
+fonts and com port settings.
+
+* If the game ends while you are dragging a piece, we now don't let you
+finish the move. Formerly the move was accepted and your opponent's clock
+would start running again.
+
+3.5.4 -- Fri Apr 18 01:15:24 PDT 1997 Tim Mann
+
+Beta test release of WinBoard and xboard. The documentation remains
+out of date.
+
+* Many fixes and improvements to new WinBoard user interface code.
+
+* In Zippy mode, avoid sending another copy of the same move to the chess
+program if ICS sends us another copy of the board image. Hard to believe
+it took me until now to diagnose and fix this problem!
+
+3.5.3 -- Sat Apr 12 19:49:33 PDT 1997 Tim Mann
+
+Beta test release of WinBoard and xboard.
+
+* Fixed fatal bug in WinBoard input handling.
+
+* Made code to stop chess program for reuse a bit smarter. Removed kludge
+of "white" in initString; it didn't work well, and is unneeded
+with Crafty 11.21 and later.
+
+3.5.2 -- Sat Apr 12 15:40:01 PDT 1997 Tim Mann
+
+Beta test release of WinBoard.
+
+* Ignore check and permit promotion to King during suicide games; no need
+to turn off TestLegality.
+
+* Renamed CheckLegality to TestLegality to avoid confusion with the chess
+term "check".
+
+* Added Rematch to Action menu.
+
+* WinBoard now has a custom ICS interaction window with scrollback, a
+separate line for input, and colorization. Accelerators that conflict
+with normal editing keys were changed (by requiring Alt+) so they can work
+in both the console and the main window.
+
+* WinBoard error popups are now non-modal and disappear when you make a
+new move, as in xboard.
+
+* Configure now defaults to --disable-ptys on all systems. If anyone has
+an ancient SysV system where pipes don't work with select, they can still
+do "configure --enable-ptys" explicitly. I would appreciate getting a bug
+report if this happens to anyone, with complete output from configure and
+"uname -a".
+
+* "make install" now makes the installation directories too.
+
+* Fixed a bug that would cause an "Illegal move" message for Black from
+GNU Chess to be incorrectly considered bogus.
+
+* Handle name changes during an ICS game (FICS bname and wname commands).
+
+* You can force both chess programs to be killed at the end of each game
+by turning off the reuseChessPrograms option. There are still some
+problems with reusing Crafty even in version 11.20.
+
+* Now the second chess program stays around by default too, if it ever
+gets started.
+
+3.5.1 -- Sat Apr 5 16:47:48 PST 1997 Tim Mann
+
+Beta test release.
+
+* Don't kill off and restart the chess program for each game; keep the
+same one running, using the "new" command to start a new game. This
+change works around the problem in Windows 95 that makes WinBoard crash it
+at times, and is generally desirable to make new games start faster. The
+second chess program (for TwoMachines) is still killed at the end of the
+game, and unfortunately this can still crash Windows 95. Temporarily
+added "white" to the initString to make this work with Crafty 11.20, which
+has a minor bug in "new". Older versions of Crafty have worse bugs in
+"new"; they should not be used with this version of xboard.
+
+* Support for FICS suicide chess: Parse illegal moves (that leave King in
+check) in game history. If CheckLegality is off, allow promotion to King
+and illegal moves in game files. We still generate e2e4 style notation
+for illegal moves.
+
+* Handle FICS "has timeseal; checking" message.
+
+* Changed the coords from white back to black; this was a bug.
+
+* Fixed problems compiling with K&R compilers.
+
+* Fixed an old bug in RegisterMove that was crashing cmail on some systems
+(notably linux).
+
+3.5.0 -- Thu Jan 2 16:59:49 PST 1997 Tim Mann
+
+Thanks to Frank McIngvale for much of the work on versions 3.4.4 and above!
+
+* Fix Crafty resumed game time bug (frankm)
+
+* Word wrap text in Analysis window (frankm)
+
+* More debug info for XPM loading (frankm)
+
+* Replaced config.sub, config.guess, etc., with up-to-date versions from
+autoconf 2.12. Hopefully this will fix problems on Pentium Pro machines.
+
+* Removed some Makefile gunk that was causing looping for one person.
+
+3.4.7 -- Thu Dec 19 14:22:41 PST 1996 Tim Mann
+
+All changes from Frank:
+
+* Retrieve ratings from ICC (and FICS, etc., when they add the Creating:
+message), save them in the PGN tags, and pass them to Crafty in Zippy mode.
+
+* Add settable time delay between characters in ICS login script.
+
+* Colorize messages like personal tells. Fix false recognition of channel
+tells.
+
+* Pass "tells" from Crafty through to ICS (in Zippy mode).
+
+* Implement ~/ filename convention from C shell for game and position file
+names.
+
+* ZIPPYACCEPTONLY feature for testing.
+
+3.4, patchlevel 6 -- Sat Nov 23 16:58:50 PST 1996 Tim Mann
+
+* Put recognition of "illegal move" messages from Crafty for
+illegal castling, etc., inside an #if that is currently turned off,
+because of a bug in Crafty that generates bogus "illegal move" messages
+after some moves that are actually legal and accepted by Crafty.
+
+* Added -checkLegality option; previously this could not be turned off.
+
+* Fixed an old bug in finding default board size parameters.
+
+* Differentiated among channel tell, kibitz/whisper, and personal tell/say.
+
+* Fixed a bug in detecting Xpm in the configure script.
+
+3.4, patchlevel 5 -- Mon Nov 18 16:22:53 PST 1996 Tim Mann
+
+* Added zic2xpm to the kit; it had been omitted by mistake.
+
+* Added some default colors for -colorize
+
+3.4, patchlevel 4 -- Sat Nov 16 18:10:17 PST 1996 Tim Mann
+
+This is meant to be a beta release in preparation for version 3.5.
+
+* Added InfoXBoard and ManXBoard to the Help menu.
+
+* Made Frank's ICS input box optional, defaulting to off.
+
+* Merged in Frank McIngvale's XbKit. Many new features, including
+-clickClick mode, the Analysis modes, piece flashing, ZIICS import,
+ICS text colorization, and the ICS input box. Many thanks to Frank for
+supplying and documenting this code.
+
+3.4, patchlevel 3 -- Mon Nov 11 18:23:14 PST 1996 Tim Mann
+
+Small set of changes made while Frank McIngvale was working on XbKit in
+parallel. Unreleased in this form.
+
+* Updated zippy.README.
+
+* Removed useless X event handler and removed strange code for copying
+form translation table to board that worked around the bug it caused.
+This makes changing bindings in .Xdefaults more straightforward.
+
+* Now pressing the Control key steps back one move, and releasing it steps
+forward again.
+
+* Moved quit from "q" to "Q" for greater safety.
+
+* Use "unobserve" instead of "observe" to stop observing; needed on FICS.
+
+* Support for interface variable.
+
+* Strip titles from people who are talking to us, so (for example) Zippy
+won't try things like "tell Darooha(*) hello". Needed on FICS.
+
+3.4, patchlevel 2 -- Tue Jul 9 19:06:42 PDT 1996 Tim Mann
+
+This patchlevel is not planned to be an announced release. It's in
+preparation for integrating Frank McIngvale's XbKit. It mostly contains
+minor fixes I've accumulated since 3.4.pl1.
+
+* WinBoard /telnet option now fires up an external program, as
+with xboard, instead of trying to use a feature of NT 3.1 that does not
+exist in later versions of NT or in Windows 95. ChangeLog for 3.4.pl1
+said this had been implemented there, but it really wasn't.
+
+* Indicating player to move by the icon color now works under Windows 95.
+
+* WinBoard now kills the chess program when you exit using the system menu
+or the [X] button. Thanks to Michael Lowe.
+
+* Minor changes to Zippy, including: Now understands wild challenges on
+FICS; these used to crash it. Removed limit on how fast a game will be
+accepted. Use "set formula ..." on the chess server to limit this if you
+are using GNU Chess. Now sends correct opponent name to Crafty.
+
+* Added some missing default values to documentation. Thanks to Stuart
+Cracraft.
+
+* Bugfix: Trying to print "No fonts match pattern" error message would
+crash. This can happen to Linux users who don't install Helvetica, for
+example.
+
+* Bugfix: Defaulting feature in -size n,n,n,n,n,n would put us in an
+infinite loop.
+
+* Added more directories to search for Athena widgets on HPUX.
+
+* New cmail (3.12) from Evan Welsh; includes small fix from Kayvan Sylvan.
+
+* Recognize "illegal move" messages from Crafty for illegal castling, etc.
+
+* Bugfix: "name" command added to zippy.c for Crafty was producing error
+message if GNU Chess was in use.
+
+* In bughouse mode, suppress holding messages from console window; show
+holdings only in banner.
+
+* Minor fixes/cleanup to Makefile.in and configure.in.
+
+3.4, patchlevel 1 -- Mon Dec 11 13:43:12 PST 1995 Tim Mann
+
+* This patchlevel updates WinBoard to match xboard, and includes a few
+fixes and minor improvements. "-size tiny" and "-size n,n,n,n,n,n"
+are still not implemented for WinBoard.
+
+* Installed support for Crafty based on code from Bob Hyatt.
+Currently the only documentation for this is in the FAQ, and a few
+things don't work with Crafty 8.23. Please do not report these
+problems as bugs in either xboard or Crafty. Bob and I know about
+them. The worst ones (if not all of them) should be fixed in Crafty
+8.24.
+
+* Changed the kludge command we send when gnuchess wants to print
+something that doesn't end with a newline, from "help" to "bogus".
+This works because the error message gnuchess prints ends with a
+newline. It also improves compatibility with Crafty, which doesn't
+need the kludge, but for which sending "help" causes a problem.
+
+* Don't draw grid at all if lineGap is 0; previously we drew the grid
+with X "0-width" lines (usually 1 pixel wide) and then overwrote it.
+
+* Makefile: Removed xboard.info from "all" target so we won't try to
+rebuild it, because this fails on hosts that don't have makeinfo
+installed. Other minor fixes to "clean" targets, etc.
+
+* Fixes and cleanup to Auto Comment code that handles continuation
+lines and highlighting.
+
+* Auto Observe now tries to observe the game from the point of view of
+the player who was on your gnotify list. Requested by rng.
+Limitations: We can't tell which player it was unless you have ICS
+highlighting turned on. Also, currently "observe foo" works as
+required (observing from foo's point of view) only on ICC, but FICS
+will probably implement this soon.
+
+* "-size tiny" now makes the default font smaller automatically. This
+was implemented by introducing an extra Form widget in the hierarchy
+for all xboard windows, named either normalLayout, smallLayout, or
+tinyLayout. So you can have resource specifications that apply only
+to certain layouts; in particular, XBoard*tinyLayout*font.
+
+* Bug fix: EditGame or EditPosition while playing or examining still was
+not really being permitted.
+
+* WinBoard bug fix: On the EditPosition menu, King did not work.
+
+* Added text catalog of WinSock error messages to WinBoard, because
+Microsoft still has not put them in the system message catalog.
+
+* Removed support for older ICS game-ending messages that do not have
+a PGN result token (*, 0-1, 1-0, or 1/2-1/2) after the closing '}'.
+The code for older messages was sometimes firing on the newer
+messages, due to parsing ambiguity. If the current code sees an old
+message, it will understand that the game is over, but will always
+display * as a result token instead of trying to guess the result by
+interpreting the text message.
+
+3.4, patchlevel 0 -- Tue Nov 21 01:02:50 PST 1995 Tim Mann
+
+* This patchlevel was released for xboard only.
+
+* Updated the info file. It should now be as up-to-date as the man page,
+with good English except in the parts that pertain only to AmyBoard.
+
+* Added "-size tiny", requested by Bob Hyatt. Also cleaned up bitmap
+support and added "-size n,n,n,n,n,n" to allow arbitrary-sized bitmaps,
+if the actual bitmaps are supplied by the user.
+
+* Updated bughouse support.
+
+3.3, patchlevel 4 -- Sat Nov 18 02:27:21 PST 1995 Tim Mann
+
+* Unreleased beta that works with preliminary FICS bughouse code. Will
+need changes before release to track FICS message changes.
+
+* Removed use of .EX macro from man page. It is not supported by some
+nroff -man macro packages, notably the one on Slackware Linux. Switched
+to boldface for references to xboard and other commands within the man
+page, as this seems to be the modern way.
+
+* Bug fix: If ICS rejected a move, it was correctly undone on the board,
+but the message widget still displayed the bad move. Reported by DAV.
+
+* Normally, xboard in ICS mode fetches the move list whenever the board
+display switches to a new game. Doing this is now an option
+(getMoveList) that can be turned off, which is useful if you are watching
+multiple blitz games. Requested by rng.
+
+* Move list fetching code is now smarter: it ignores a move list if it is
+not for the right game.
+
+* Added support for bughouse as implemented on FICS. Holdings are shown
+in the window title in place of the strength numbers. A menu on mouse
+buttons 2 and 3 (same on both) lets you drop pieces. There is no checking
+as to whether you actually hold the piece you are trying to drop; we rely
+on ICS to check that. Notation of the form P@f7 is generated and parsed.
+The mate detector does not understand that non-contact mate is not really
+mate in bughouse, but this does no real harm. It results in a "#"
+suffix being displayed on the move notation, but xboard does not assume the
+game is over.
+
+* Bug fix: Promotion to a knight was not working with ICC! Thanks to
+Wendigo for the report.
+
+* Bug fix: Special pty code for host types *-*-aix3* and *-*-irix3*
+(supplied from configure.in) had a bug that would cause childio.c to
+fail to compile, due to a "continue" that was not within a loop.
+
+* Bug fix: In pgntags.c, memory was being freed while still in use. One
+symptom this caused was that on some machines, cmail would fail with a
+message that it could not find the BlackNA tag. The error was in some
+submitted code that I included in version 3.2.pl3 without reading
+carefully enough. Anders Forberg noticed the symptoms, and Evan Welsh
+(who had nothing to do with causing the bug) found the bug and submitted a
+fix; thanks to them both.
+
+* Removed restriction against using EditGame while playing, observing,
+or examining on ICS. You still get a warning popup.
+
+3.3, patchlevel 3 -- Sat Sep 16 11:44:05 PDT 1995 Tim Mann
+
+* Bug fix: Going directly from MachineWhite to TwoMachines mode would kill
+off the second chess program after Black's first move.
+
+* Added -timeIncrement feature. Thanks to Joel Rivat.
+
+* Deleted code that tries to keep you from observing more than one game,
+or observing while playing or examining. There is actually no problem in
+doing this, except that every time an update comes in from a different
+game than is currently being displayed, xboard fetches the history of the
+new game, which may be time-consuming if you are on a slow link.
+
+* Fixed configure so as not to crash when neither lex nor flex is found.
+lex or flex is needed only if the user wants to rebuild parser.c. Thanks
+to Phil Humpherys for reporting the crash.
+
+* Bug fix: config.h.in used #define instead of #undef for some macros used
+in the pty code in childio.c. This causes the code to fail to compile on
+some architectures, because the symbols are supposed to be undefined, not
+defined to empty, when they are not set in configure. Bug originated in
+3.3.pl0 when config.h was introduced. Thanks to Phil Humpherys for report.
+
+* Bug fix: ShowThinking would not show anything when current position had
+no move to display in the move window. E.g., if position was created by
+LoadPosition or EditPosition.
+
+3.3, patchlevel 2 -- Mon Aug 28 11:11:11 PDT 1995 Tim Mann
+
+* Zippy code was omitted from xboard-3.3.pl1 by mistake; now included.
+
+* For WinBoard, added hint to help file that you may need to turn off
+LocalLineEditing while typing dialing commands to your modem.
+
+3.3, patchlevel 1 -- Sat Aug 19 15:13:30 PDT 1995 Tim Mann
+
+* Zippy distribution is no longer separate from regular xboard distribution.
+
+* Deal properly with Show Thinking output from GNU Chess when it is
+thinking on its opponent's time. In TwoMachines mode this output is
+suppressed to avoid interfering with the output from the machine that is
+on move; in other modes it is displayed (including the move that GNU Chess
+is predicting the user will make next). GNU Chess produces this output
+only if it is built without -DQUIETBACKGROUND defined; this symbol is
+defined by default in patchlevels before pl75, but undefined by default in
+pl75.
+
+* Bug fix: Handling of initial board position in move list for wild games
+was broken, so wild games could not be observed and adjourned wild games
+could not be continued. Thanks to "Maximum Entropy" for the bug report.
+
+* Added feature: algebraic notation now shows "+" indicator for check
+and "#" for checkmate, as called for in PGN standard. Thanks to Kevin
+Maher for the suggestion.
+
+3.3, patchlevel 0 -- Thu Jul 27 22:21:07 PDT 1995 Tim Mann
+
+* Changed configuration to use a config.h file instead of passing zillions
+of -D options on the cc command line.
+
+* Merged a small fix and some updates to the texinfo file from Jochen
+Wiedmann. The texinfo file still needs work.
+
+3.2, patchlevel 5 -- Tue Jul 18 20:29:39 PDT 1995 Tim Mann
+
+* Beta test release of xboard only.
+
+* Updated WinBoard code to include new xboard features.
+
+* Added texinfo file from Jochen Wiedmann to the release, but not as the
+primary documentation. It needs updating, and the English needs work.
+I did make a few improvements, mostly to change incorrect uses of @var to
+either @samp or @code as appropriate.
+
+* Merged in code changes to 3.2.pl4beta from Jochen Wiedmann.
+
+* Fixed EditComment; did not pop up window in previous beta.
+
+* Added AutoComment feature.
+
+* Added GameListDestroy to disable the outdated game list popup in cases
+where we load a new game file without building a new popup.
+
+* Added yyskipmoves feature to parser.l to speed up building of gamelist.
+
+* gamelist.c wouldn't compile with a non-ANSI compiler. Fixed.
+
+* Change to yy_text handling in patchlevel 3 still had problems. Can't
+use AC_DECL_YYTEXT in configure.in, because that defines YYTEXT_POINTER
+according to whether the lexer on the current host makes yytext a pointer.
+But most people will be using a parser.c that was generated on another
+host and shipped with the package.
+
+3.2, patchlevel 4 -- Sun Jun 25 19:13:43 PDT 1995 Tim Mann
+
+* Beta test release of xboard only.
+
+* Added FIREWALLS section to man page.
+
+* Changed -icsport to be a string. Now with the -telnet option,
+specifying -icsport "" suppresses the second argument to telnet.
+
+* Added EditTags feature. Removed AboutGame from menu, because EditTags
+subsumes it. EditTags suggested by Jochen Wiedmann and first implemented by
+him in AmyBoard. xboard implementation is my own.
+
+* Fixed some missing or incorrect prototypes.
+
+3.2, patchlevel 3 -- Sat Jun 3 18:57:38 1995 Tim Mann
+
+* Beta test release of xboard only.
+
+* New version of cmail from Evan Welsh, to fix compatibility problems with
+perl 5.0.
+
+* Added game list feature on Load Game, based on code from Jochen
+Wiedmann. Integrated it with cmail.
+
+* Several bug fixes from Jochen Wiedmann, including one to my yy_text
+workaround for the difference in the type of yytext between lex and flex.
+
+* Handle clock pause on FICS.
+
+* Suppress clocks in untimed FICS games (time control 0 0).
+
+* Rebuilt configure script with autoconf 2.3. This fixes a bug in
+configuring for X11R6, where -lSM -lICE would not be added when needed.
+
+* Fixed inconsistent type declarations on IntSigHandler and
+CmailSigHandler. Bug report from Josh Daynard.
+
+* backend.c wouldn't compile with a non-ANSI compiler. Fixed.
+
+3.2, patchlevel 2 -- Tue Feb 7 14:50:30 1995 Tim Mann
+
+* Minor release of both xboard and WinBoard.
+
+* Added recognition of some FICS messages. On the other hand FICS is also
+changing some of its messages to match what xboard already recognizes.
+
+* Temporarily went back to using "promote" command on ICS instead of
+"a7a8=Q", because FICS doesn't implement the latter yet.
+
+* We now avoid using overlapped I/O on pipes in WinBoard, to make Windows
+95 beta 2 happy. This lets WinBoard work with GNU Chess on Windows 95!
+
+* Installed patches from Jochen Wiedmann to coordinate with Amiga XBoard.
+
+* Installed patch to cmail bug in LoadGame from Evan Welsh.
+
+* Bugfix: checkmate and stalemate moves entered with EditGame in ICS mode
+were not being handled correctly. Bug was in GameEnds().
+
+* Implemented EchoOn and EchoOff for xboard, using system("stty echo\n").
+Now passwords won't be echoed when you connect directly to ICS. Also,
+telnet negotiation characters aren't displayed (when possible).
+
+* Implemented more of the telnet protocol. Now connecting to a telnet
+server with "-icsport 23" should work even without giving the -telnet
+option. The telnet is in "old line-by-line mode".
+
+3.2, patchlevel 1 -- Sat Dec 10 13:50:46 1994 Tim Mann
+
+* This patchlevel released for WinBoard only.
+
+* winboard.c: Fixed ConsoleInputThread(). Needed to change CRLF to LF,
+not to CR. This was stopping normal /ics mode from working. Thanks to
+Asher Kobin for the bug report.
+
+* winboard.c: Fixed Raw(), EchoOn(), EchoOff(). Now they take effect
+immediately, not on the next console read after the one in progress.
+
+* winboard.c: Attempted to make WinBoard work with gnuchessx running
+directly on Windows (not remotely via rsh). It now works on NT, but only
+if gnuchess is told not to think on its opponent's time ("easy\n" removed
+from initString). The problem seems to be that GenerateConsoleCtrlEvent
+is not doing anything. On Windows 95 beta 2, we get error messages on
+both reading and writing to gnuchessx; I didn't investigate why.
+
+3.2, patchlevel 0 -- Wed Dec 7 13:23:36 1994 Tim Mann
+
+* Thanks to all the beta testers who gave me feedback: Josef Nelissen,
+Steve Booth, Evan Welsh, Dima Dakhnovsky, Chris Petroff, Peter Jansen,
+Derek Terveer, Michel van der List, Richard Lloyd, Shelly Mistry, and Mike
+Lee. Sorry if I forgot anyone. Thanks to Virendra Kumar Mehta for
+information about DYNIX/ptx.
+
+* Don't exit on keyboard EOF unless we get two in a row.
+
+* WinBoard only: added -localLineEdit switch to allow turning off local
+line editing if you really want to. It is still a bad idea to let the
+echoing be done remotely, however; see below.
+
+* Fixed some configure problems on HP-UX. [Steve Booth]
+
+* Fixed (I hope) configure problem on SunOS 5.3/Solaris 2.3. [Josef Nelissen]
+
+* cmail bugfix from Evan Welsh (cmail 3.4).
+
+3.1, patchlevel 9 -- Fri Dec 2 23:54:56 1994 Tim Mann
+
+* Beta distribution only
+
+* Always do local echo/edit of user typing in ICS mode. Doing the echo
+downstream may seem nicer in some modes, and it can be hard to turn that
+echo off, but the echoed characters can be interleaved with ICS output
+and make it impossible to parse correctly. For xboard this involved only
+a change to recommendations in the man page, as Raw() isn't implemented.
+For WinBoard, removing Raw() made a real difference. Added code in
+WinBoard to change /r/n back into /r on keyboard input, as we get the
+former when Raw() is not called.
+
+* Do not issue ICS "refresh" command after we start to observe a game
+unless we get to the next prompt without seeing a board image. Newest
+version of ICS doesn't require this refresh, but old versions around still
+do.
+
+* cmail bugfix and small code cleanup in LoadGame, from Evan Welsh.
+
+* Added keyboard accelerators N/P for LoadNextGame/LoadPreviousGame. Evan
+Welsh request.
+
+* Using "-" on the command line as a filename for loading (saving) games
+or positions specifies the standard input (standard output). Alain Picard
+suggestion.
+
+* On WinBoard only, a command line option without a leading '-' or '/' is
+now taken as the value of -lgf.
+
+* Changed to not use stdin, stdout, stderr as initializers in backend.c;
+needed for GNU libc compatibility. You also must build parser.c with flex
+(not lex) if you are using GNU libc, to avoid having the same problem
+there.
+
+* Changed WinBoard to avoid using "overlapped" input on the console. It
+now seems to fully work on Windows 95 beta 2.
+
+* Improved comment popups on WinBoard. Now newlines are handled properly,
+and the plain Comment popup window doesn't disappear and reappear when we
+step to a new move with a new comment.
+
+* Fixed bugs in detecting the absence of the time and otim commands.
+
+* Added built-in implementation of rcmd protocol to WinBoard. Windows NT
+does not implement passing signals through rsh, and Windows 95 does not
+have rsh at all.
+
+* Added -remoteUser option.
+
+3.1, patchlevel 8 -- Mon Nov 28 15:26:07 1994 Tim Mann
+
+* Beta distribution only
+
+* Rearranged ChangeLog file into reverse chronological order to be closer
+to GNU standards.
+
+* Integrated new cmail code from Evan Welsh (including cmail RCS rev 3.2).
+Includes a bug fix to TruncateGame.
+
+* Updated ICS address to be chess.lm.com.
+
+* Bug fixes to handling the aftermath of FatalError. Thanks to Chris
+Petroff for the bug report.
+
+* Test for remsh before rsh, other fixes for HP-UX. Thanks to Richard
+Lloyd. I wasn't able to do all the things he suggested, so there may
+still be some rough edges in building on HP-UX. See the FAQ file for hints.
+
+* Bug fix; added missing check for HAVE_SYS_SYSTEMINFO. Thanks to Josef
+Nelissen for testing on Solaris 2.x.
+
+* Updated WinBoard to match xboard. (WinBoard still has a few option
+dialogs that don't exist in xboard.)
+
+* Changed Hint output to a popup.
+
+* ShowThinking output and move output no longer overwrite each other.
+ShowThinking output won't appear if the displayed position is not current.
+ShowThinking output in TwoMachines mode made clearer and documented.
+
+* Implemented --enable-ptys and --disable-ptys arguments to configure.
+
+* Fixed Book and Hint code to work over a pty with echo enabled and tabs
+expanded to spaces. Thanks to Dima Dahknovsky for the bug report.
+
+* Moved Attention calls from all over xboard to one place, inside
+SendToProgram.
+
+* Added bulletproofing to ShowThinkingEvent.
+
+* Added code to handle "refresh N" boards that come in from ICS properly,
+assuming ICS is changed to mark them with a new relation code (-3).
+
+3.1, patchlevel 7 -- Sun Nov 13 22:16:01 PST 1994 -- Tim Mann
+
+* Beta distribution only
+
+* Changed ShowThinking to just show the current best line in the
+DisplayMessage area, instead of dumping everything to stdout.
+
+* Installed new cmail (RCS rev 3.1) and cmail.man (RCS rev 1.10), and
+changes to cmail code in backend.c, from Evan Welsh.
+
+* Miscellaneous minor fixes.
+
+3.1, patchlevel 6 -- Fri Nov 4 12:53:53 PST 1994 -- Tim Mann
+
+* This patchlevel was not actually released to anyone.
+
+* Updated the pty code to be based on GNU Emacs 19.24, and moved it to a
+separate file. It was hard to split out just the pty configuration from
+all the stuff emacs does with its custom configure script and .h files,
+but I did my best.
+
+* Converted from imake to GNU autoconf. This was a serious upheaval.
+
+* Put in code to help trap "error gathering move list" problem reported by
+Michel van der List if it recurs. I couldn't reproduce it.
+
+3.1, patchlevel 5 -- Mon Oct 31 21:12:00 PST 1994 -- Tim Mann
+
+* Beta distribution only.
+
+* We now test for checkmate or stalemate in EditGame mode after every user
+move, and in LoadGame mode whenever we hit the end of a game without
+seeing a PGN end marker. cmail needs an update to deal with this
+correctly; Evan promises one.
+
+* Bugfixes in new move generator. Thanks to Mike Lee for reporting one of
+the bugs.
+
+* Imakefile was omitted from patchlevel 4.
+
+3.1, patchlevel 4 -- Mon Sep 19 18:19:46 PDT 1994 -- Tim Mann
+
+* Beta distribution only.
+
+* The move generator includes a mate tester. Initially this is used only
+by cmail, and even that usage needs further work.
+
+* Wrote a true move generator and used it to replace all the move
+disambiguation and legality checking code in parser.l. The move generator
+is capable of dealing correctly with en passant and castling availability,
+but the rest of the program still does not keep track of this information.
+
+* Bug fix: xboard did not handle "foo has made you an examiner of game 23"
+message. Thus you could not use examine features until the next board
+came in, showing your new relation to the game. Thanks to POOKIEWOOKIE on ICS
+for the bug report.
+
+* Added AutoObserve feature. Thanks to Chris Petroff for the idea.
+
+* Added Book feature to use new gnuchess "bk" command. Mike McGann request.
+
+* Redid code to handle missing "time" command in gnuchess, because latest
+gnuchess no longer sends a response to this command.
+
+* Eliminated need for -DFLEX. Thanks to Michael Shields (Vladimir?) for
+the idea.
+
+* Added missing code to implement MoveNow in TwoMachines mode.
+
+* Added ShowThinking feature. Thanks to Richard Lloyd for the idea.
+
+* Applied patches from Evan Welsh; some fixes and improvements to the
+cmail code.
+
+* Fixed bug in moving from EndOfGame mode to MachineWhite or MachineBlack,
+introduced in previous patchlevel. Also fixed related bug in ending a
+game in ICS mode; was entering EndOfGame mode instead of IcsIdle.
+
+* Added patch to implement internetChessServerLogonScript flag, from Kevin
+O'Connor. Thanks!
+
+3.1, patchlevel 3 -- Wed Sep 7 13:22:07 PDT 1994 -- Tim Mann
+
+* Beta distribution only.
+
+* Merged in new cmail code from Evan Welsh. He added the ability to have
+more than one game per message, needed for official IECG matches. I added
+the ability to resign or offer/accept/decline a draw in a cmail game.
+
+* Bugfix: invalid -tc option caused segmentation fault; DisplayFatalError
+was called too early in initialization. Georges Honore reported this bug.
+
+* Decided to keep EndOfGame mode as an element of the user interface---it
+means that a gnuchess game or loaded game has ended, and the user must
+explicitly select EditGame to edit it, rather than just being able to
+enter more moves freely. But internally there is no longer an invariant
+tying this mode to whether the chess program is running.
+
+* Zippy bugfix: Was saving only the final position in the -sgf file when
+the game ended by something other than resignation or flag. Also fixed
+the longstanding bug that Zippy would think the final board of such a game
+was a new game and restart the chess program.
+
+* Now does a better job of faking castling availability in FEN. We still
+don't really keep track of it, but now at least we don't say that castling
+is still available when the king or rook is not on its home square.
+
+* Bugfix: Initial board of game history for wild games was going through
+too much processing, causing us to forget the game length, which is now
+needed by ParseGameHistory. This was causing problems with resuming
+adjourned wild games.
+
+* Updated ICS host to ics.onenet.net.
+
+* Zippy now accepts challenges where the opponent specified his color.
+
+* Added ZIPPYPASSWORD2 to let operator give commands directly to gnuchess.
+
+* Bitmap directory can include alternative icons now, too.
+
+* Handle "Game * (*) has no examiners" message from ICS.
+
+* Revamped window title and icon name selection.
+
+3.1, patchlevel 2 -- Sun Jun 12 17:16:28 PDT 1994 -- Tim Mann
+
+* "Beta" distribution for Zippy users only.
+
+* Bugfix: common.h was assuming that X11 type Boolean is char, which is
+not always true. This might have caused all sorts of obscure bugs!
+
+* Installed new bitmaps from Elmar Bartel as the default. Many thanks!
+The old bitmaps can be used by changing the "bitmaps" symbolic link before
+compiling xboard, or by using the -bitmapDirectory option at runtime.
+
+* Loading a game that ends with the PGN unfinished symbol ("*") now always
+leaves you in EditGame mode.
+
+* Added documentation of -icscomm to man page. Thanks to Maarten Remkes
+for the linux script.
+
+* ^C now kills gnuchess as well as xboard. Thanks to Dima Dakhnovsky for
+reminding me how to do this.
+
+* Bitmap icon color now indicates player to move. Stuart Cracraft
+suggestion.
+
+* Changed piece bitmap flags to have just one flag, which points to a
+directory full of bitmaps, instead of a flag for each bitmap. Also
+changed bitmap naming convention.
+
+* "Connection closed by ICS" is no longer a FatalError popup. This was
+too annoying in the normal case where the user typed "quit".
+
+* Changed default font to 14 pixels instead of 10 points. This seems to
+make it close to the size I want it to be on more displays.
+
+* Major mode (GNU Chess, etc.) appears in title bar. Stuart Cracraft
+request.
+
+* Bug fix: EditGameEvent, MachineBlackEvent, MachineWhiteEvent, and
+TwoMachinesEvent were calling PauseEvent to get out of pause mode, which
+now has undesired side effects, such as advancing the display to the
+forwardMostMove. It works fine to just set pausing = FALSE instead.
+
+* IcsExamining mode now lets you access ICS edit position commands using
+the same popup menus as xboard's EditPosition mode. Thanks to DAV on ICS
+for inspiring the idea.
+
+* Corrected test for gcc on HP in Imakefile; thanks to Richard Lloyd.
+
+3.1, patchlevel 1 -- Wed Jun 1 16:25:11 PDT 1994 -- Tim Mann
+
+* Added parser.c.lex and parser.c.flex to the distribution.
+
+* Added HP gcc options to Imakefile, from Mats Nylen.
+
+* EndOfGame mode no longer highlights EditGame mode indicator, because the
+modes really do differ. I would like to get rid of EndOfGame mode in the
+future, at least as far as users can see.
+
+* Larger %a in parser.l, needed for RS/6000 users.
+
+* Minor improvements to Mail Move error messages.
+
+* When -debug flag is given to xboard, -v is passed to cmail.
+
+* Old Save Style uses "1. ..." instead of "1..." when black moves after a
+comment; more like xboard 3.0's actual style.
+
+* New version of cmail from Evan Welsh. Looks for UCB Mail in a more
+portable way and has some minor bug fixes.
+
+* Bug fix: Saving a FEN position while in EditPosition mode with black to
+play was showing white to play in the saved position.
+
+3.1, patchlevel 0 -- Fri May 20 16:36:15 PDT 1994 -- Tim Mann
+
+* This is the first general release since 3.0, patchlevel 9. Releases
+since then have been limited-distribution or beta releases.
+
+* Thanks to my version 3.1 beta testers: Dmitry Dakhnovsky, Ed Hanway,
+Richard Lloyd, Mike McGann, Shelly Mistry, Josef Nelissen, Chris Petroff,
+Jack Robertson, Michel van der List, Ky Macpherson, Derek Terveer, and
+Evan Welsh. Sorry if I've forgotten anyone who gave me feedback.
+
+* Updated man page.
+
+* Minor cleanup on menu sensitivity code.
+
+* Integrated another even better version of cmail from Evan Welsh,
+including some code he supplied in xboard itself.
+
+* A few more fixes to cmail support.
+
+* Automatically update clocks after an ICS "moretime" command.
+
+* Handle ICS automatic examine mode (set examine 1) after a game.
+
+3.0, patchlevel 14 -- Tue May 17 13:41:44 PDT 1994 -- Tim Mann
+
+* Beta test release only.
+
+* Don't suppress prompt on first board of game being examined; otherwise
+it looks like nothing happened at all (i.e., like you're lagged).
+
+* Added StopExamining and StopObserving (Chris Petroff suggestion).
+
+* Made Reset do a refresh on ICS. John Chanak's original ICS code for
+xboard tried to do this; I finally decided it was a good idea after all.
+
+* Fixed bugs in handling updates that come in while you are pausing in
+examine mode. This is pretty tricky to do right.
+
+* Made un-Pausing immediately pop you to the current position. This is
+always necessary in examine mode, since the game may have changed under
+you; your remembered moves might no longer be right. So I made it do the
+same in all modes.
+
+* Took Detach Examine mode back out...used Pause mode for this instead!
+
+* Put in a trap for the GNU Chess bug of printing an Illegal Move message
+when its own hint move is illegal.
+
+* Attempted to fix a Zippy bug; bogus "exited unexpectedly" messages after
+it checkmates its opponent. This involved adding an argument to GameEnds
+to say who says it ended (ICS, GNU, etc.) and taking different actions in
+different cases. Unfortunately, this just restored an older Zippy bug, where
+Zippy restarts gnuchess when it gets the board with the final position,
+because GameEnds still puts xboard in EndOfGame mode. Sigh.
+
+* We now capture elapsed time on last move when getting game history.
+(Josef Nelissen bug report)
+
+* Rewrote code to redisplay last file title so it really works.
+
+* Fixed bug in oldSaveStyle.
+
+* Larger %a and %o were needed for lex.
+
+3.0, patchlevel 13 -- Mon May 16 16:26:22 PDT 1994 -- Tim Mann
+
+* Beta test release only.
+
+* FatalError popups stay on the screen now. If the error is really fatal,
+all functions are disabled, and the program exits when you press OK.
+
+* Redisplay last file title when using Load (Next/Previous/Same) Game.
+
+* Zippy understands new match challenge message format on ICS.
+
+* Added Revert command.
+
+* When examining a game on ICS, < > buttons do ICS backward/forward
+commands, unless you set the Detach Examine option. Thanks to Dima
+Dakhnovsky for the idea.
+
+* Fixed various minor problems in cmail mode.
+
+* cmail generates the tags now. New version of cmail from Evan Welsh.
+
+* cmail mode won't let you do MailMove unless the currently displayed
+position is exactly one move past the end of the game you loaded.
+
+* Fixed building of man pages in Imakefile
+
+* Updates to INSTALL file
+
+3.0, patchlevel 12 -- Sat May 7 21:10:03 PDT 1994 -- Tim Mann
+
+* Beta test release only.
+
+* Brought man page up to date.
+
+* Added Shift+R to resign from keyboard.
+
+* Some items on Action menu available in GNU Chess mode now.
+
+* Revamped Action menu.
+
+* Reordered functions in backend.c as a small step toward reorganizing
+this whole mess.
+
+* Generate TimeControl PGN tag.
+
+* Get type of ICS game (e.g., rated blitz) and save in PGN tags.
+
+* Bug fix: Clocks were not redisplayed when entering EditGame mode.
+
+* Bug fix: Clocks were not being redisplayed after loading a game file
+with -td 0, so they could show the wrong color active.
+
+* Bug fix: Chess programs would be killed and match mode would exit
+prematurely when loading a PGN game fragment ending with "*".
+
+* ICS command "sposition" no longer confuses xboard.
+
+* Integrated new version of cmail (with support code in xboard) from Evan
+Welsh.
+
+* Added TruncateGame, MoveNow, RetractMove, and QuietPlay.
+
+* Bug fix: switching between MachineWhite and MachineBlack was not calling
+Attention(). Reported by Dino Dini.
+
+* More improvements to INSTALL and Imakefile.
+
+* Pack moves into 79 character lines in PGN output. We don't generate
+check indications, and we always break the line before the result,
+so this is not quite PGN export format.
+
+* Use FEN tag in PGN.
+
+* Improved finding and counting of game starts in save files.
+
+* Negative position or game numbers in -lpi/-lgi mean to seek to that byte
+offset. Hook for possible future features, not in man page.
+
+* Detect and handle absence of either "time" or "otim" commands in
+gnuchess.
+
+* Don't use "promote" command to ICS anymore.
+
+* Handle switching sides and taking back moves on FICS.
+
+* Handle flip state flag in style 12 board.
+
+* Handle examine mode on ICS.
+
+* Improved error popups for various kinds of illegal moves.
+
+* Suppress unasked-for hints from gnuchess (which it generates in post
+mode).
+
+* Load/save position functions use FEN. Old style also supported.
+
+* Added detailed error messages if loading a bitmap file fails.
+
+* Small board has 2-pixel lines between squares instead of 3-pixel.
+
+* Added OldSaveStyle and AboutGame.
+
+* Renamed ForceMoves to EditGame.
+
+3.0, patchlevel 11 -- Tue Sep 21 15:25:36 PDT 1993 -- Tim Mann
+
+* The following changes were present in xboard 3.0, patchlevel 11, but the
+first group did not make it into WinBoard 3.0 until later. xboard
+3.0.pl11 was a limited-distribution release only, mostly to Zippy users.
+
+* Man page minor fixes.
+
+* Added a missing file close.
+
+* Removed automatic error popdown on Reset, which was destroying some
+error messages before they could be read.
+
+* Fixed char vs. unsigned char warnings on bitmaps.
+
+* Use ICS board style 12. Some improvements to ICS parsing.
+
+* Comment window is now labelled with the move the comment is on, and
+comments don't pop down when you step to the next move.
+
+* Save files now in PGN format.
+
+* Support for loading PGN files. PGN tags pop up when a PGN game file
+is loaded.
+
+* More info in INSTALL and Imakefile about building for Suns (and
+other systems).
+
+* WinBoard 3.0 patchlevel 11 split off from an early version of xboard
+3.0 patchlevel 11, so it does not have all the features of that
+patchlevel. The following changes made it into both xboard and
+WinBoard:
+
+* Made Comment dialog non-modal in WinBoard.
+
+* EndOfGame mode is now more transparent. It looks like ForceMoves
+mode except that there is no chess program running.
+
+* Small bug fixes in clock management. Most noticeably, pausing when
+it is gnuchess's move now works as documented (again).
+
+* Add minimal support for -icscomm option. Not documented yet because
+I haven't sorted out the issues with setting the tty modes on the comm
+port device, or with locking it properly. But it's usable by wizards.
+
+* Don't restart the chess program upon Backward event from EndOfGame mode.
+
+* Suppress extra prompt after ICS sends us a board.
+
+3.0, patchlevel 10 -- Sat Sep 11 18:44:03 PDT 1993 -- Tim Mann
+
+* Beta test release only.
+
+* Zippy now plays chess. zippy.c and zippy.h are still not included
+in the standard distribution, but are available on request.
+
+* Switched to using style 12 on ICS.
+
+* Updated man page, and documented use of XBoard*form.translations to
+add more shortcut keys.
+
+* Added shortcut keys "d" to claim/offer/accept a draw, and "t" to
+call flag. Suggested by venu on ICS.
+
+* More explicit instructions in INSTALL file.
+
+3.0, patchlevel 9 -- Tue Sep 7 14:02:00 PDT 1993 -- Tim Mann
+
+* General release, minor update to 3.0.pl8.
+
+* Loosened checking on whether it's okay to start a move, to satisfy
+ICS ultra-blitz players. Now we don't check whether it's your turn
+until you let go of the piece.
+
+* Parser now recognizes "+-+" as meaning the game ended in a draw.
+
+* Got rid of S_NONE symbol, which seems to conflict with some symbol
+Sun defines.
+
+* Tweaked the man page. Clarified that there is currently no way for
+two people running copies of xboard to play each other without going
+through the Internet Chess Server.
+
+* Fixed a bug in color name conversion. Asking for two different
+colors whose names were the same in the first four characters would
+get you two copies of the first one. Thanks to Volker Zink for the
+bug report.
+
+* Improved confusing Usage() message.
+
+* Added a bunch of Sun information to the Imakefile and INSTALL file.
+Thanks to Ed Hanway, Arik Klingensmith, and others who responded.
+
+* Test for defined(WIN32) instead of !defined(unix).
+
+* Avoid using (void *) type with non-ANSI C compilers. Thanks to
+James Altucher for the bug report.
+
+3.0, patchlevel 8 -- Thu Sep 2 12:23:01 PDT 1993 -- Tim Mann
+
+* Note: Patchlevel 8 was the first non-beta release of xboard 3.0
+
+* Added cmail to distribution. Contributed (and still maintained) by
+Evan Welsh.
+
+* Bug fix: -queen option wasn't initializing menu check. Reported by
+Pat Surry.
+
+3.0, patchlevel 7 -- Thu Aug 26 13:23:24 PDT 1993 -- Tim Mann
+
+* Sent WinBoard 3.0.pl7 to Torre on ICS
+
+* Added parser.h to hold the interface to parser.l
+
+* Upgraded COPYING file and copyright notices to GNU GPL version 2.
+
+3.0, patchlevel 6 -- Tue Aug 24 15:16:13 PDT 1993 -- Tim Mann
+
+* We no longer display intermediate positions or intermediate comments
+while loading a game file with -timeDelay 0 or loading an opening to
+start up a -matchMode game.
+
+* Loading an empty game from an xboard save file now gives a status
+message "No moves in game" instead of an error popup saying "Game not
+found in file."
+
+* Added comment.awk to distribution.
+
+3.0, patchlevel 5 -- Tue Aug 17 16:45:54 PDT 1993 -- Tim Mann
+
+* Bug fix: xboard would crash if it couldn't get all its colors; now
+it switches to monoMode instead. Also, xboard was trying to convert
+color resources even when using a b/w display. Reported by Larry
+Rogers.
+
+* Bug fix: Declared fields of TimeMark as signed so that we get signed
+instead of unsigned arithmetic. SubtractTimeMarks was breaking on
+Alpha AXP (which has 64-bit longs) with old declarations. Reported by
+Michel van der List.
+
+* Bug fixes: Keyboard accelerators now work after EditComment window is
+popped down. Iconize keyboard accelerator now works even if xboard
+was started with -iconic flag and later deiconized.
+
+* Bug fix: The routine that tests whether a move is illegal because it
+would leave you in check was not handling e.p. captures properly.
+Reported by Patrick Surry.
+
+* Bug (?) fix: Was adding time to clocks at time control even when
+loading a game file. Actually it's not entirely clear how time
+controls should be dealt with when some moves are loaded from a file
+or clicked in with ForceMoves. For now ForceMoves mode does add the
+time (because it can be used to change moves during a live game), but
+LoadGame mode does not.
+
+* Updated usage message.
+
+* Previous attempted fix to matchMode had broken TwoMachines mode and
+generally needed more work. Also simplified command line interface to
+matchMode.
+
+3.0, patchlevel 4 -- Thu Aug 5 14:17:18 PDT 1993 -- Tim Mann
+
+* Thanks again to the beta testers listed for 3.0 patchlevel 3, and also
+Desnogues, Steve Cariglia, Niklas Engsner, Mark Silver, and Roger Rowe.
+
+* Reorganized man page, splitting OPTIONS into subsections.
+
+* matchMode was very broken; fixed.
+
+* Changed convention for turning off command line options from --opt
+to -xopt, to be less inconsistent with GNU standards. Also changed
+the long command line options to take True/False arguments like
+resources; seems to make more sense this way.
+
+* Added AlwaysQueen option -- suppresses promotion dialog and always
+promotes to a queen if you move a pawn to the last rank. Has no
+effect on gnuchess (or your ICS opponents!) -- they can still
+underpromote.
+
+* Subtracted an extra fudge term when determining how wide message and
+title widgets should be. This fixes a problem some beta testers had.
+Wish I knew why it's needed.
+
+* Bugfix in parser; symptom was that you couldn't do LoadGame after
+observing a game on ICS.
+
+* Bugfix in Forward; didn't work after game ended while Pause was turned on.
+
+* Removed bogus execute bits on .h files.
+
+* Use REMOTE_SHELL and TELNET_PROGRAM definitions.
+
+* MachineWhite and MachineBlack now work from TwoMachines mode.
+
+* Popping down an error message with the [ok] button was not turning off
+the errorUp flag, so the next move would cause xboard to try to pop it
+down again, resulting in a wild memory reference and sometimes a crash.
+
+3.0, patchlevel 3 -- Tue Aug 3 17:40:27 1993 -- Tim Mann
+
+* Thanks to my beta testers: Patrick Surry, Takuya Kojima, Robert J. Luoma,
+Chris L. Petroff, Richard K. Lloyd, Michel van der List, Craig Metz,
+Antoon Frehe, Simon Clift, Shelly, Eric Peterson, Christopher Mitchell,
+Martin Koch, Ed Hanway, Steve Booth, Udo, Ken Hobday, and Joseph Duhamel.
+
+* Improved error messages for trying to move the wrong color pieces or
+to move when it's not your turn.
+
+* Special code for monoMode on 1-bit displays now understands displays
+where 1=white and 0=black.
+
+* Declare getenv() if <stdlib.h> not included; avoids a compiler warning.
+
+* Documented borderXoffset and borderYoffset.
+
+* Added -titleInWindow option for use with X window managers that
+don't let us set the title in the window banner.
+
+* Fixed error message printing in WinBoard; system error messages no
+longer appear as numeric codes.
+
+* The error message popup is now non-modal; you don't have to press the
+[ok] button before you can do something else. In addition, the popup is
+positioned so that it doesn't cover up the board (too much), and making a
+move or otherwise clicking on the board pops it down. (Not implemented in
+WinBoard.)
+
+* You can now call your opponent's flag in ICS mode by clicking on his
+clock.
+
+* Fixed minor bugs in -flipView option and documented exactly how xboard
+decides which way to flip the view.
+
+3.0, patchlevel 2 -- Fri Jul 30 22:20:23 PDT 1993 -- Tim Mann
+
+* Added Autosave to Options menu. Would be better to have Save
+Options dialog as in WinBoard, but this was quick to do and gives the
+most-needed functionality.
+
+* Changed "Reload Game" on menu to "Reload Same Game".
+
+3.0, patchlevel 1 -- Thu Jul 8 21:22:59 PDT 1993 -- Tim Mann
+
+* Sent a copy of patchlevel 1 to Patrick Surry to beta-test.
+
+* Added -cmail option that sets appData.cmailMode. Currently a no-op.
+In the future this may set special modes for use by the cmail script
+for playing chess by email.
+
+* Added LoadNextGame, LoadPreviousGame, and ReloadGame to File menu.
+ReloadGame suggested by Patrick Surry.
+
+* Added -flipView command-line option. Suggested by Patrick Surry.
+
+* Fixed bugs in parser.l: (1) Pattern for "# xboard game file ..."
+needed to match to end of line. (2) Start of a new file was not matching
+the ^ start-of-line character. The fix for this is a kludge.
+
+* Made game counting code in LoadGame more robust, and made LoadGame
+able to detect the end of a saved partial game (by noticing the start
+of the next game) in game files created by XBoard itself. We don't
+try to find the start of the next game that way in other kinds of game
+files, because the only way I can think of to do that is to look for
+another move #1, and that technique gets too many false hits.
+
+* Fixed recently introduced bug in LoadGame when game starts with a
+position diagram.
+
+3.0, patchlevel 0 -- Fri Jun 25 14:17:17 PDT 1993 -- Tim Mann
+
+* Changes in this patchlevel were too numerous to list. Larger ones are
+listed below.
+
+* Added a popup dialog to enter and edit comments. Inspired by some
+code from Patrick Surry. Changed the normal read-only comment popup
+to the same style.
+
+* Added ICS init script feature from Karl Schwamb.
+
+* Added some ESIX fixes and OMIT_SOCKETS ifdef option, from Kayvan Sylvan.
+
+* Revamped code to allow use of flex instead of lex on parser.l.
+Using flex requires adding -DFLEX to defines in Imakefile.
+
+* Source code is split into front end (xboard.c), which knows about X
+and Unix, and back end (backend.c), which knows about chess, gnuchess,
+and the ICS. There is also a front end for Windows NT.
+
+* Boolean command line options now use "-foo" to turn on and "--foo"
+to turn off instead of "-foo true" and "-foo false". [Later -xfoo;
+see above.]
+
+* Added menu commands to control autoflag, bell, and coords options.
+
+* User interface has a new look: (1) Menu bar instead of array of
+buttons. A few very commonly used features have small buttons in
+addition to being on the menus. (2) Large font for clock. (3) Pop-up
+dialogs for errors.
+
+2.1, patchlevel 11 -- Sat Jun 5 00:01:01 PDT 1993 -- mann@src.dec.com
+
+* Added code to deal with "wild" games on ICS. This includes allowing
+castling with the king on d1 or d8, which is allowed in wild(1) games
+if the king started there. Notation is o-o to castle "short"---to
+whichever side the king is closer to---and o-o-o to castle "long."
+Right now wild castling is always allowed by xboard; we rely on ICS or
+gnuchess to reject it when we aren't really in wild mode.
+
+* memcpy call had arguments in wrong order.
+
+* Removed April Fool code
+
+2.1, patchlevel 10 -- Mon Feb 15 10:19:31 PST 1993 -- mann@src.dec.com
+
+* Avoid trying to select on a pipe when using System V. Needed to
+copy some code from InitChessProgram() up into establish().
+
+* Bug fix in disambiguating pawn moves like "ed".
+
+* Fix to error handling in ReceiveFromProgram.
+
+* Bug fix: entering EditPosition mode with black to play highlighted
+White's clock instead of Black's.
+
+* Added telnetProgram resource in case "telnet" is not the name of the
+telnet program.
+
+2.1, patchlevel 9 -- Fri Jan 22 19:08:27 PST 1993 -- mann@src.dec.com
+
+* Entering Force Moves mode clears "flag has fallen" messages from display.
+
+* ICS host name can now be in numeric format; for example 128.2.232.4.
+
+* Bug fix: LegalityTest was failing to test whether a pawn move was
+illegal because the move would discover a check.
+
+* Handle ICS message "mann asserts a win over manntest, who disconnected."
+
+* Bug fix: A recent change to PromotionCallBack had broken
+underpromotion to a knight.
+
+* Bug fix: In EditPosition mode, dragging a piece onto a square border
+would make it vanish. xboard wasn't distinguishing this case from
+dragging the piece off the board. Thanks to Matthew Kidd.
+
+* Removed "static" declaration from yywrap for compatibility with IRIX
+version of lex. Thanks to stiller@blaze.cs.jhu.edu.
+
+* Added substitutes for bzero, bcopy, and gethostname for Solaris
+SVR4. Thanks to Michael Grant.
+
+* Bug fixes to queen move disambiguation. Bugs showed up only when
+promotion resulted in more than one queen on the board.
+
+2.1, patchlevel 8 -- Fri Dec 11 17:54:18 PST 1992 -- mann@src.dec.com
+
+* parser bug fix: It now really works to leave off the piece a pawn is
+promoting to and let it default to queen.
+
+* When starting to observe or play an ICS game, don't draw board in
+initial position and then immediately redraw it in the current
+position.
+
+* Handle ICS messages when an "abuser" forfeits a game by
+disconnecting and when a game is aborted ("removed") by an
+administrator.
+
+* Bug fix: A user move when in LoadGame+Pause mode was resuming the
+game load instead of putting us in force mode.
+
+* It seems that crashes inside sscanf when xboard is compiled with gcc
+(as on IBM PS/2 AIX, mentioned below, and also on VAX Ultrix 3.1) are
+caused by an incompatibility between gcc and the sscanf implementation
+on these platforms. A workaround is to specify -fwritable-strings to
+gcc (see the gcc documentation). Added info on how to do this to the
+Imakefile. Thanks to Tom McConnell for this information.
+
+* Clocks are allowed to go negative. This is mostly for ICS
+compatibility, but it affects gnuchess mode too. Also, we give the
+time bonus when a player hits the time control boundary even if his
+flag is already down. This choice is a bit debatable, but it makes
+things look better when you are in TwoMachines mode and gnuchess's
+time management screws up causing it to exceed its time limit.
+
+* Implemented move legality checking code. Moves made with the mouse
+or parsed from a file are checked for legality before being made.
+This is mostly in preparation for future extensions, such as
+human-human play. For now it makes -noChessProgram mode more useful.
+
+* If the user takes back moves, we restore the clocks to the earlier
+settings.
+
+* We now handle the output of the ICS oldmoves command, including
+parsing the game end condition.
+
+* Added autoCallFlag mode.
+
+* Fixed glitches in the medium size outline king and rook bitmaps, and
+touched up the medium size solid king and outline queen.
+
+* bug fix: DisplayMove would not display backwardMostMove - 1.
+
+* Added CallFlag button and removed AcceptMatch. CallFlag is more
+important with new ICS, and accepting the current match offer is easy
+with the new ICS command "accept" (can be abbreviated "ac").
+
+* LoadGame and LoadPosition display tail of file name (plus index
+number, if any) as title.
+
+* MachineWhite, MachineBlack, and TwoMachines now work properly from
+LoadGame and LoadGame+Pause mode.
+
+* Use o-o and o-o-o to castle on ICS, not 00 and 000.
+
+* Stripped out code for old ICS messages; new ICS is now installed.
+
+* Bug fix: don't offer autosave when paused during LoadGame.
+
+2.1, patchlevel 7 - Fri Dec 11 17:40:56 PST 1992 - mann@src.dec.com
+
+* Track change to "Illegal move" message in new ICS.
+
+2.1, patchlevel 6 -- Tue Dec 8 10:48:44 PST 1992 -- mann@src.dec.com
+
+* Kludged around bug in keeping comment popup where you put it by
+adding borderXoffset and borderYoffset resources that give the width
+of the borders added by the window manager. Yucch.
+
+* Changed searchDepth kludge back to using "help" instead of "bd"; the
+latter didn't work because the output contains a line starting with
+"White", so we think gnuchess is telling us that White won. Oops.
+
+* Removed some code that uses an X11R5 feature, XrmGetDatabase.
+Without this, the auto font sizing code is harder to make work, so to
+keep my sanity I had to change it to affect only the fonts that appear
+in the main window and the comment popup, not the other popups. Maybe
+this is better anyway.
+
+* AcceptMatch button now works after a counterchallenge, too.
+
+* Added code for more variants of messages about games being adjourned
+or aborted. These messages need to be unified in new version of ICS.
+
+* Added workaround for minor bug in ICS; game number on first board
+can be wrong.
+
+* Removed code to say "refresh n" instead of "refresh"; was broken and
+wasn't needed anyway.
+
+* Added missing casts for compilers that distinguish enums from ints
+and missing cast in connect call.
+
+* Added code to recognize "both sides are out of time" draw message
+proposed for next version of ICS.
+
+* Thanks to Danny Sleator and Joe Peterson for bug reports.
+
+2.1, patchlevel 5 -- Sun Dec 6 19:52:40 PST 1992 -- mann@src.dec.com
+
+* Removed gcc and CDEBUGFLAGS from Imakefile.
+
+* Corrected setting of mode to ForceMoves when game file ends or
+contains an AmbiguousMove or BadMove. Previous bug was harmless.
+
+* Added AcceptMatch button and mention of 50-move rule for Draw button
+to man page.
+
+2.1, patchlevel 4 -- Sun Dec 6 02:55:42 PST 1992 -- mann@src.dec.com
+
+* Now handles revised messages from new version of ICS. New ICS is
+not released yet, so this code might change further. Next patchlevel
+will remove support for old ICS; both are there now.
+
+* Initial processing for a new game being watched or played now
+happens when we see the first board image. Removes the need to parse
+some messages and unifies some code.
+
+2.1, patchlevel 3 -- Tue Dec 1 19:40:40 PST 1992 -- mann@src.dec.com
+
+* Handles ICS messages "Draw : neither player has mating
+material" and "Draw : White has no material, Black has no time."
+
+* Added AcceptMatch button for ICS mode.
+
+* Fixed bug in previous fix to yylexstr().
+
+* Fixed bugs in code for loading old position files that don't start
+with "#" and for handling case where user asked for nth position in
+file but there aren't that many.
+
+* Handles ICS message "* has restored your old game"
+
+* ResetProc always clears title line now.
+
+* Don't issue just "refresh" when watching a game; use game number.
+Upcoming new version of ICS may need this.
+
+* Added code to try to prevent user from watching and/or playing more
+than one game at a time. There is a race condition inherent here; if
+we get more than one board from the game before our command to stop
+watching it takes effect, we'll think the user started it again. Not
+clear how to fix this.
+
+* Redid ParseBoard8 to use sscanf. Code is a good deal cleaner now.
+Also, we now parse out the game number too, though we don't make much
+use of it yet.
+
+* (Tried to put in a feature that recognizes the current game in a
+game file must have ended when we see the start of a new one, but had
+to disable it because we have too many false hits with the current
+parser, especially in gnuchess listing files.)
+
+* Moves read from game files or received from ICS are now translated
+into canonical algebraic form just like all other moves. Minor nit:
+If you use Reset while playing or observing a game in ICS mode, the
+game history (including the current board position) is lost, so the
+next move of the current game can't be translated.
+
+* Default fonts now vary with board size, and are chosen by pixel size
+instead of point size (since piece bitmaps have a fixed pixel size).
+
+* Bug fix: An extra Forward was required to skip over time indications
+in game files.
+
+2.1 patchlevel 2 -- Fri Nov 27 23:30:00 PST 1992 -- mann@src.dec.com
+
+* If you move the comment popup, the next time it pops up it will come
+back where you put it.
+
+* Fixed yylexstr() so calls to it can be interspersed with calls to
+yylex().
+
+* Fixed bugs in Forward/Backward while in LoadGame mode.
+
+* Changed Save{Game,Position} functions to append instead of
+overwriting if file exists. Changed Load{Game,Position} functions to
+deal with multiple games/positions per file.
+
+* Changed load{Game,Position}File resources to trigger automatic load
+on program startup. Changed save{Game,Position}File resources to
+trigger automatic save after every completed game and on program exit.
+
+* Added autoSaveGames mode.
+
+* Fixed bug with PromoPiece in call to MakeAlg from MakeMove.
+
+* Many changes to get rid of picky compiler warnings and generally
+clean up the code.
+
+2.1 patchlevel 1 -- Fri Nov 27 02:45:00 PST 1992 -- mann@src.dec.com
+
+* A last minute change before patchlevel 0 went out broke
+ParseGameHistory(). Immediately fixed in patchlevel 1.
+
+Version 2.1, patchlevel 0 -- Fri Nov 27 02:00:00 PST 1992 -- mann@src.dec.com
+
+* Uses "time" command of gnuchess 4.0 and following to keep clocks in
+sync. Still works with older versions without this command; we test
+whether the command is present the first time each chess program is
+started.
+
+* File name dialog pops up under the mouse cursor, so that it's got the
+keyboard focus if the window manager is using pointer focus.
+
+* Attempts to move the wrong color piece or an empty square are filtered
+out in xboard instead of being passed on to GNU Chess or the ICS.
+
+* The reason a game ended is now remembered even if you move backward
+and forward after it ends. It is forgotten only if you make a move
+(which is as it should be---this is now a different game, which hasn't
+ended yet). The message saying why the game ended no longer wipes out
+the last move.
+
+* Pause, Backward, Forward, ForceMoves, and EditPosition now work from
+TwoMachines mode.
+
+* Forward and Backward now change only the board display unless you
+are in ForceMoves mode. Pause mode keeps new moves that are received
+from being displayed on your screen until you unpause (or use
+Forward).
+
+* Added option to ring the bell after opponents' moves.
+
+* Saved games that start from other than the standard initial position
+now begin with a postion diagram as in saved position files. The
+loader is modified to understand such save files.
+
+* Improved error checking when trying to read from gnuchess.
+
+* Parser understands things that look like time indications, e.g., (0:12),
+instead of popping them up as comments.
+
+* Send "quit" to gnuchess before trying to kill it. I needed this
+locally because sending a SIGTERM to rsh was not killing the remote
+program on some internal field test systems we have.
+
+* Merged in code from John Chanak to make xboard a front end to the
+Internet Chess Server, and added several improvements of my own.
+(These include parsing end of game messages, loading the current state
+and previous history of a game that's joined in progress via "watch"
+or "load", automatic switch from board style 1 to 8 when needed,
+removing irrelevant buttons and adding some new ones, adding the
+useTelnet and gateway resources, and miscellaneous code cleanup, bug
+fixes, and documentation.) Many thanks to John for writing and
+contributing the initial version of this code.
+
+Fri Oct 30 20:16:40 PST 1992 (patchlevel 25) mann@src.dec.com
+
+* gnuchess now castles by sending us "o-o" or "o-o-o" (starting with a
+preliminary version of 4.0.pl60 that I have). Added code to handle
+this. The old format ("e1g1", etc.) still works too.
+
+* Added code to format moves in normal abbreviated algebraic notation
+(for example, e4, exd4, f8Q, Nf6, 0-0) instead of coordinate algebraic
+(for example, e2e4, e3d4, f7f8q, g1f6, e1g1). Moves entered with the
+mouse or received from gnuchess are translated into this canonical
+format for display on the message line or in saved game files. Moves
+read from game files are not translated, however; they are shown and
+saved just as they appear in the file.
+
+Mon Sep 14 13:19:01 PDT 1992 (patchlevel 24) mann@src.dec.com
+
+* It's not really correct to write an ep capture of a pawn on e5 as
+fxe5; this should be written as fxe6 because e6 is where the capturing
+pawn ends up. Nevertheless, the parser now interprets fxe5 as the ep
+capture f5xe6 unless there is a pawn on f4, in which case it
+interprets fxe5 as f4xe5. By design, the parser does not flag fxe5 as
+ambiguous if there are pawns on both f4 and f5; instead it prefers the
+more legitimate f4xe5 interpretation.
+
+* A move like fxe6 or fe6 is now interpreted as an e.p. capture of the
+pawn on e5 if there is one there and e6 is empty.
+
+* A move like fxe5 can no longer be interpreted as an e.p. capture if
+there isn't a pawn on e5 to be captured. Previously this could happen
+erroneously if there were pawns on both f4 and f5, and the f4 pawn was
+capturing a piece on e5.
+
+* The parser no longer munges the move it is parsing; in the past, for
+instance, it would remove the "x" from a move like dxc5 before echoing
+it to the screen.
+
+* The parser now detects when a move is ambiguous and returns an
+error, instead of arbitrarily choosing one possibility as it used to.
+
+Mon Aug 10 18:40:47 PDT 1992 (patchlevel 23) mann@src.dec.com
+
+* Added code so parser can handle fully qualified algebraic, e.g.,
+Ng1-f3, N/g1-f3, Ng1f3, or even Pe2-e4. The "P" and "/" work only for
+fully qualified moves, not generally.
+
+* Fixed parser bugs in handling moves with rank or file disambiguator,
+e.g. N1f3 or Ngf3.
+
+Mon Jul 6 17:55:32 PDT 1992 (patchlevel 22) mann@src.dec.com
+
+* AIXV3 patch from Tom McConnell; thanks!
+
+* After hitting the Backward button we see the last move made instead of
+the word "Pausing" displayed.
+
+* Fixed a couple of problems compiling on IRIX; thanks to Michel Arsenault
+and Alan Walsh for bug reports and help with fixes.
+
+* Added optional display of algebraic notation coordinates along left and
+bottom edges of board. This was inspired by some code from Jean-Christophe
+Engel; thanks!
+
+* Swapped EditPosition and Pause buttons to reduce danger of losing the
+game in progress by hitting EditPosition when you wanted Backward. Thanks
+to Ove Lundberg for complaining (though it bugged me too).
+
+* Despite one complaint, I kept the feature of changing both clocks when black
+makes time control, rather than changing each individually when the player
+involved makes it. This is to avoid having it look like White is way ahead on
+time while Black is thinking about the last move of the time control period
+(i.e., when White has made time control but Black hasn't yet).
+
+* Corrected clocks to work as in real tournaments. Time is *added* when you
+reach time control; previously the clocks were simply set to the length of the
+new time period. Also, when a player's flag falls, he still does not receive a
+new time allotment at the next time control, but his opponent does still
+receive more time if *his* flag has not fallen; previously, time controls were
+ignored for both players if either flag fell. I forget who reported this bug.
+
+* Added a small ESIX patch from Kayvan Sylvan.
+
+Mon Jun 22 13:24:38 PDT 1992 (patchlevel 21)
+
+* Added some SVR4 support code from Ronald Cole. It's Greek to me.
+
+* Note: Stephen Meatheringham reports a bug causing xboard to crash with an
+error from the X server when run on a Sun Sparcstation IPX with Solaris 1.0.1
+and OpenWindows 3.0. This bug has not been tracked down yet.
+
+* Fixed a problem with ATTENTION code. On some operating systems, you have to
+be even more cautious about when you send a SIGINT to gnuchess, because the
+signal handler gets deinstalled each time it is used, and gnuchess does not
+reinstall it immediately. In particular, if you send a SIGINT and make an
+illegal move or ask for a hint, gnuchess does not reinstall the handler until
+*after* you make your next move, so you had better not send a SIGINT before
+it. I put a workaround for this case into xboard; I hope there are no more.
+
+* The ATTENTION code is needed when compiling for the ESIX operating system,
+because ESIX has a bug in the FIONREAD ioctl, so the code in gnuchess that
+lets you interrupt its thinking on your time just by typing in your move does
+not work. Perhaps gnuchess will have a workaround for this eventually.
+
+* Fixed yet another bug in using XtGetValues; code to inhibit shell resizing
+was leaving a null pointer as the place to store the current sizes.
+
+* Man page fixes: corrected -sl to -sd, updated LIMITATIONS.
+
+* Added include of <sys/time.h> conditional on HAS_GETTIMEOFDAY. I hope this
+works for all systems; on mine, <time.h> and <sys/time.h> are the same file,
+but with an #ifndef that makes it harmless to include both.
+
+* Thanks for reports from Mike Pearlman, Stephen Meatheringham, Kayvan Sylvan,
+d87-mal@nada.kth.se, Urban Koistinen, and Ronald Cole.
+
+Mon Jun 8 11:39:18 PDT 1992 (patchlevel 20)
+
+* Documented default value of initString and explained what it means. This
+paragraph also serves to inform the user that xboard by default will tell
+gnuchess to think on his time, something one user apparently didn't understand.
+
+* Redid -searchDepth (formerly -searchLevel) and -searchTime code. They both
+work correctly with gnuchess 3.1 now. The -searchDepth option also works
+correctly with gnuchess 4.0. The -searchTime option does not work with
+gnuchess 4.0.pl50 or earlier because those gnuchess versions do not have a
+working searchTime feature. Instead of having xboard do a half-baked emulation
+of this feature by using a 1-move time control, I will be submitting a patch to
+the gnuchess folks to restore the feature as in 3.1.
+
+* Improved clock code. It now keeps accurate track of fractional seconds of
+clock running time, if your system has gettimeofday(); if not, it is generous
+about them---if a clock has been going for n.m seconds when it is stopped, only
+n seconds are charged. Previously, xboard would charge one second immediately
+when a clock was started, so if n.m had elapsed when it was stopped, n+1 would
+be charged. This should stop xboard from thinking gnuchess has let its flag
+fall on the last move of a time control, as it often did before. I also
+improved the comments and condensed the code a little. I hope there are no
+systems that have X11 and don't have gettimeofday(), but if there are, I'd like
+to know what to replace it with.
+
+* "Flag dropped" messages now show up on the top line, beside the clocks, so
+that they don't obscure more interesting messages on the second line.
+
+* Fixed confusion of NULL and '\000'.
+
+* Include time.h to get ctime() declaration.
+
+* Fix to "parser bug" messages in parser.l.
+
+* Changed code to work with old-fashioned tolower() macro that requires its
+argument to be an uppercase letter.
+
+* Minor fix to some usage error messages; was reversing program name and
+erroneous argument value.
+
+* Thanks to Mitch Wright, Ranier Orth, and Henrik Schmiediche for bug reports.
+
+Fri Jun 5 13:06:08 PDT 1992 (patchlevel 19)
+
+* Note: xboard does not seem to work when compiled with gcc 1.40 on a
+PS/2 running AIX. It crashes at the sscanf in line 768 of xboard.c.
+You can work around the problem by specifying the -timeControl option
+on the command line instead of defaulting it. This does not seem to
+be a bug in xboard itself; it runs okay on PS/2 AIX when compiled with
+MetaWare High C. [But see 2.1.pl8 above.]
+
+* Removed bogus files from distribution.
+
+* Changed variable name that conflicted with SVR4 ttyname function.
+
+* Thanks to Christoph Strozyk for another bug report, and to several
+of the folks mentioned under patchlevel 18 for testing it.
+
+Wed Jun 3 17:50:37 PDT 1992 (patchlevel 18) mann@src.dec.com
+
+* Added an include of sys/fcntl.h to pick up the definition of O_RDWR for
+System V users.
+
+* Fixed a bug in CatchPipeSignal; was testing the wrong variable to determine
+which chess program got the signal.
+
+* Removed the declaration of strrchr, which was causing problems for some
+people, and added an include of <string.h> or <strings.h> instead.
+
+* Fixed a bunch of type errors uncovered by compilers that check more carefully
+than the one I was using. I just patched many of them with casts---typically
+cases where a function didn't take the same number and type of arguments as the
+X header file prototype said it should---because I didn't see any other way to
+fix them. The versions of the X header files that I have don't actually have
+full prototypes for these function types; they declare only the return type and
+just give the argument types as comments.
+
+* InitChessProgram returns immediately if chess program died while we were
+waiting for it to say "Chess". I think this fixes a bug that could make xboard
+crash or go into an infinite loop printing "Warning: Select failed; error code
+9" if gnuchess crashed there.
+
+* Removed code that tries to put the file descriptor used to read messages from
+gnuchess into nonblocking mode. I don't see how this kludge could ever have
+fixed the problem it was intended to (see below), and it seemed to be causing
+a race condition when we were waiting for the initial message from gnuchess
+after it started up.
+
+* Thanks to Richard K. Lloyd, Konstantinos Konstantinides, Mark
+Seiden, Erik Schoenfelder, Andreas Stolcke, Rainer Orth, Henry Thomas,
+and Kris Van Hees for bug reports and help with fixes.

+Sun May 31 08:00:00 PDT 1992 (patchlevel 17) Bart Massey bart@cs.uoregon.edu
+
+* 'xboard' suffered from a couple of serious bugs. An initial
+ size needed to be given to the message label to avoid a race
+ condition (!) so I gave it some text (otherwise occasionally
+ xboard would fail because the message widget was 0 width under
+ MIT X11R4). The sizes needed to be Dimension, not int, because
+ they were written in by Xt -- on my big-endian box Dimension
+ is short, causing chaos. Also, I hacked a declaration in for
+ strrchr() to shut the compiler up -- this is arguably a kludge,
+ but I couldn't think of anything better; maybe you can.
+
+Fri May 22 13:40:50 PDT 1992 (patchlevel 16)
+
+* First real (non-beta) release of version 2.0.
+
+* Added GNU copyleft notices covering version 2.0 enhancements.
+
+Thu May 21 12:30:09 PDT 1992 (patchlevel 15)
+
+* Removed -g from Imakefile.
+
+* Added casts in parser.l to prevent warning messages from some C compilers.
+
+* Bugfix: code to exit if chess program couldn't be started had bug in error
+message printing.
+
+Tue May 19 11:58:06 PDT 1992 (patchlevel 14)
+
+* Fixes one small bug: If LoadGame does not find a game in the file, it resets
+xboard to BeginningOfGame mode (as if the Reset button was pressed), instead of
+leaving it in LoadGame mode.
+
+Mon Apr 13 18:32:27 PDT 1992 (patchlevel 13)
+
+* Improved error handling when gnuchessx crashes. Now displays a message and
+enters EndOfGame state without exiting. This should help with diagnosing
+gnuchessx problems, since the position and move history are not lost.
+
+* Debugged man page.
+
+Version 2.0 -- Thu Apr 2 16:04:54 PST 1992 (patchlevel 12)
+
+* Added small 40x40 pixel pieces; board size now specified as small, medium, or
+large.
+
+* Improved man page.
+
+* Saved position files now say "white to play" if it's white's move.
+
+* SavePosition while in EditPosition mode now gets side to play right.
+
+* Made "Pawn" the default on edit position menus.
+
+* Removed "To play" from edit position menus, since it's redundant. Left
+support code in so it can be restored if someone wants it.
+
+* Tightened parser's definition of a move number to help further with skipping
+over stuff before the first move.
+
+* Put back feature of skipping over stuff in game files before a start of game
+marker. This helps when loading electronic mail messages that have things
+like "00" in the header (looks like castling), or that talk about moves in
+running text before the actual game score. Tradeoff is that we can't load
+games that don't either have move numbers or say "gnuchess game" just before
+the moves.
+
+* Changed version number to 2.0 because others have used "1.3" for patched
+versions of 1.2. Display version number and patchlevel at startup.
+
+Thu Apr 2 15:30:22 PST 1992 (patchlevel 11)
+
+* Bugfix: Match started with TwoMachines button now handles the case where
+user loaded/edited a position *and* forced some moves.
+
+* added error message feedback to many cases where the user's button press is
+rejected because it isn't allowed in the current mode.
+
+* added -noChessProgram option to allow use as a passive chessboard without
+gnuchess, replacing old buggy scheme that tried to do this automatically when
+gnuchess was not found on the search path.
+
+* parser accepts "=" in front of promotion piece
+
+* parser accepts ":" notation for captures
+
+* Removed SwitchSides button to make room for EditPosition. Left code in
+place, ifdef'ed out.
+
+* Added EditPosition mode.
+
+* Reformatted xboard.c to eliminate long lines.
+
+* Promotion popup now appears near rank to which pawn is moving.
+
+* UI improvement: Button representing current program mode is kept highlighted.
+
+* Bug fix: Hint button is now disabled when machine is on move.
+
+Sat Mar 21 14:57:37 PST 1992 (patchlevel 10)
+
+* TwoMachines now works from MachineWhite or MachineBlack mode.
+
+* ForceMoves and Backward/Forward now work at the end of a game started by
+the TwoMachines button.
+
+* Sends o-o or o-o-o to gnuchess instead of O-O or O-O-O.
+
+* Bug fix: SwitchSides button is now disabled when machine is on move.
+
+* Added -searchLevel option and corrected handling of -searchTime to reflect
+the way gnuchess really handles command line options instead of what the
+documentation used to say. Allowed optional ":seconds" on times.
+
+Tue Mar 17 21:00:35 PST 1992 (patchlevel 9)
+
+* Removed non-working code that tried to recover when a remote chess program
+could not be started; now exits with a message instead.
+
+* Now waits for chess program to print its first message (normally "Chess")
+before sending it any commands.
+
+* Matches between two machines can now start from a black-to-play position or
+black-to-play opening.
+
+* Bug fix: The program would sometimes lose track of the board position after
+the end of the game, drawing a board full of white pawns next time it got an X
+redraw request. Now fixed.
+
+* Cleaned up handling of illegal moves in game files. Now we just stop reading
+and go into ForceMoves mode.
+
+* Saved games against gnuchess indicate who won (restored and debugged 1.2
+feature).
+
+* Setting -searchTime turns off -clockMode.
+
+* My trick for setting up a black-to-play position broke in the transition from
+gnuchess 3.1+ to 4.0. Installed a different trick that works with both.
+
+* Bug fix: Was clobbering memory by mallocing one byte too few for the file
+name in SetupPositionFromFileProc. This usually resulted in a crash on the
+second attempt to load a position from a file.
+
+Mon Mar 16 16:49:00 PST 1992 (patchlevel 8)
+
+* Game and position files are saved in CHESSDIR as well as loaded from there.
+We actually chdir there, so gnuchess listing files also wind up there.
+
+* Underpromotion moves from gnuchess really work now.
+
+Sat Mar 14 14:55:24 PST 1992 (patchlevel 7)
+
+* Cleaned up lots of bugs and kruft in parser.l. It's a wonder the old version
+worked at all. Improved rejection of random text interspersed with the moves.
+
+* Relabeled buttons to reduce confusion (Play From File --> Load Game;
+Setup From File --> Load Position).
+
+* Bug fix: Doesn't exit at the end of a game that was started by pressing
+the Two Machines button.
+
+* Bug fix: Doesn't get confused if you hit Machine Black (White) while
+the machine is already playing black (white) and is on move.
+
+* Prints "White to play" or "Black to play" after loading a position file.
+
+* Bug fix: No longer hangs if no start-of-game is found in a game file.
+
+* More permissive about game file format. The first line is not assumed
+to be a header comment unless it starts with "#". We don't insist on
+seeing a "1." before the first move.
+
+* Added pop-up dialog to allow underpromotion. Moving a pawn to the last rank
+pops up a dialog to let you select what piece to promote to. Also added code
+to handle underpromotion moves from gnuchess or from a game file correctly.
+
+* Added code to send SIGINT to gnuchess before trying to move, if gnuchess
+might be busy thinking on our time. The code is ifdef'ed out because it's
+not necessary; only beta-test versions of gnuchess 4.0 at patchlevel 19 or
+below require it.
+
+Mon Feb 24 20:10:22 PST 1992
+
+* Merged fixes received from Stuart Cracraft and Mike McGann, to iconic mode
+and to ShutdownChessPrograms. (They both sent the same fixes.) I did not
+install the change that removed "easy" from the initialization string, so
+xboard will still try to run gnuchessx in "hard" mode (thinking on opponent's
+time) by sending this command.
+
+Version 1.3 -- Thu Dec 19 18:19:00 PST 1991 mann@src.dec.com (Tim Mann)
+
+* I've fixed a slew of bugs in this version of xboard:
+
+* You can now back up from the end of a game, even if gnuchess was playing
+against you. Since gnuchess exits upon mate or draw (when it's not in force
+mode), this feature works by starting up a new copy of gnuchess and feeding it
+the saved starting position and moves. Drawback: the new gnuchess starts with
+clocks at the beginning of a fresh time control.
+
+* Note: the "force" command to gnuchess is a toggle. I fixed a couple of
+places in xboard where "force" was being issued when gnuchess was already in
+force mode, which resulted in chaos. I don't know if they were in 1.2 or if I
+added them myself in the course of putting in new features.
+
+* ForceMoves button is now legal in PlayFromFile mode. It closes the game file
+and lets you force moves (or go Backward) from whatever position you've
+reached.
+
+* The parser now recognizes "white resigns" and "black resigns" (in any
+combination of upper and lower case, with or without the closing "s"). These
+used to be misinterpreted as meaning "white wins" or "black wins" respectively!
+Added "1 - 0" and "0 - 1" as equivalents for "1-0" and "0-1".
+
+* I removed the parser feature of considering "!" as a comment delimiter.
+"!" is so common as an annotation in game scores that this feature seems like a
+very bad idea.
+
+* Added a wait() after each successful call to kill() to avoid leaving zombie
+processes around.
+
+* Removed the feature of putting an indication of how the game ended into the
+internal move list when playing from a file. The only benefit of this was that
+it would get written back out if you saved the game at that point. This
+feature doesn't seem too useful, since you are unlikely to save a game you've
+read in without making any changes, and it caused a lot of problems in the code
+and user interface. The end condition is still displayed as a message when
+it's first read in from the file. End conditions when playing against gnuchess
+are still saved, too.
+
+* programName is now the last file name component of argv[0], not all of it.
+
+* xboard.c got three compiler warnings due to arguments that didn't match the
+prototypes on X toolkit functions. I got rid of them by adding some casts, and
+adding extra unused arguments to the ReceiveFromProgram function.
+
+* As I received it, the distribution had an extra period glued on the front
+of every line that started with a period. This broke the manpage in an
+obvious way. It also broke parser.l in a nonobvious way that stopped
+PlayFromFile from working.
+
+* Fixed one or two bugs where the clock was started when it shouldn't have
+been. I think one example was if you tried an illegal move in ForceMoves mode.
+
+* Now starts the machine's clock if you hit MachineWhite when white is on move
+or MachineBlack when black is on move.
+
+* Now updates the to-move indicator (highlight on clock display) when you use
+Forward/Backward or ForceMoves.
+
+* gnuchess 3.1+ has a bug that makes it try to think on its opponent's time
+even when in force mode; this causes problems with xboard's SetupFromFile
+command because gnuchess's saved hint move is garbage after the new position is
+loaded, so gnuchess prints out an error message when it tries to think about
+what it would do if the user made this move. Here is a patch for gnuchess
+3.1+:
+
+*** nondsp.c~ Mon Dec 2 12:37:18 1991
+*-- nondsp.c Thu Dec 19 15:36:06 1991
+***************
+*** 1223,1229 ****
+ ok = flag.quit = false;
+ player = opponent;
+ ft = 0;
+! if (hint > 0 && !flag.easy && Book == NULL)
+ {
+ fflush (stdout);
+ time0 = time ((long *) 0);
+*-- 1223,1229 ----
+ ok = flag.quit = false;
+ player = opponent;
+ ft = 0;
+! if (hint > 0 && !flag.easy && Book == NULL && !flag.force)
+ {
+ fflush (stdout);
+ time0 = time ((long *) 0);
+
+* SavePosition/SetupFromFile now handle black-to-play positions. If it's
+black's move in a saved position, the line "black to play" is printed
+immediately after the board display. Upon loading a position, xboard
+looks for "black" at the beginning of this line to determine whether it's
+black's move.
+
+* SetupFromFile now leaves you (effectively) in ForceMoves mode. This
+eliminates some cases where the program would get into an inconsistent state,
+and hopefully is more intuitive for the user, too.
+
+* PlayFromFile now leaves xboard in ForceMoves mode after playing through all
+the moves in the file. You can use Backward/Forward, make moves, get gnuchess
+to join the game with MachineWhite or MachineBlack, etc. The game file can end
+with either white or black to play.
+
+* Backward/Forward now seem to work in all cases. Previously using these
+buttons during a game against the machine would get xboard out of sync with
+gnuchess's idea of what was going on, resulting in chaos. Now using these
+buttons puts xboard in ForceMoves mode; you can bring gnuchess back into the
+game using the MachineWhite or MachineBlack buttons.
+
+Thu Jun 27 15:06:25 PDT 1991
+
+ * Remove comment popups during a reset.
+
+ * Bug in my forward move fix. Didn't work for playgamefile mode.
+
+Thu Jun 20 15:04:06 PDT 1991
+
+ * Can't do a backward move when it isn't your turn because gnuchess
+ gets confused. Similar bug for forward move. Do a bunch of moves,
+ back up move and go forward. These get filtered out now.
+
+ * Put easy back into the initString. This DISABLES easy mode which by
+ default is ON.
+
+ * New-line wasn't always being added to forward move strings sent to gnuchess.
+
+ * Parsed comments as [ ..............text follows ] into d7d5
+
+ * Long game file comments cause core dumps on HP systems.
+
+ * Multiple uses of the get positition file button got confused
+ on the second click.
+
+ Minor fixes to the 1.2 release
+
+Version 1.2 -- Tue Jun 11 17:14:12 PDT 1991
+
+ * For version 1.2, Jeff Kenton, Richard LLoyd, David Jensen, Martin D.,
+ Bill Schmidt, Scott Hemphill, Paul Vaughan and Bill Shauck all found
+ a lot of bugs that we put into xboard just to see if they were paying
+ attention. They were.
+
+ * Changed the protocol that xboard uses to work with the new version of
+ gnuchessr.
+
+ * There was an off by one error with the clock resetting code. Also,
+ the clock display highliting was wrong. Thanks to Bill Shauck for
+ pointing these out.
+
+ * enumerations are not really integers on some C compilers. I added casting.
+ The new version of gnuchess expects the "go" command for two machine
+ and machine plays white cases. The whiteString resource is for
+ compatibility with previous gnuchess versions which get confused by go.
+ Thanks to Martin D. for catching these.
+
+ * Fixed a bug where the checkmate message wasn't being parsed and xboard
+ kept playing. Also, the message was added to game file if saved.
+ Thanks to Scott Hemhill for pointing this out.
+
+ * Fixed a bug where saving a long game, resetting and saving a short game
+ resulted in appending the end of the long game to the short one.
+ If a game is just being played out and there is no reason for gnuchessr
+ to be used, ignore pipe signals. This allows people to use xboard
+ as a chess board without need for gnuchess. Also, trivially bad moves
+ such as e2e2 are not passed on to gnuchessr but instead ignored out of
+ hand. This allows people using xboard as a chessboard with gnuchessr
+ to pick a piece up, think and put it back down without making a move.
+ Thanks to Jeff Kenton for pointing these out.
+
+ * Added the CHESSDIR environment variable. Game and position files are
+ found in this directory. If this variable is not declared, then the
+ current directory is used. File names starting with / are treated
+ specially.
+
+ * The bitmap file names were changed so that none exceeded 14 characters.
+ This is necessary for R5.
+
+ fcntl(from_prog[0], F_SETFL, O_NDELAY);
+
+ The xboard fix was to set non-blocking i/o on the read pipe for gnuchessr
+
+ printz ("Illegal move (no matching move generated)");
+
+ * fixed a problem with the new version of gnuchessr where xboard wasn't
+ getting gnuchessr error messages for illegal moves. The problem seems
+ to be fixed *without* any gnuchess changes but this is likely to be
+ highly system dependant. There should be a new line on line 246 of nondsp.c
+
+ * -iconic doesn't work at all now. The Iconify() does work. This was
+ a tradeoff and it is really an Xt bug.
+
+ * Fixed a compiler warning for gcc and an error for the IBM RT compilers.
+ This is the VOID_PROC macro in xboard.h. Thanks to David Jensen for this.
+
+ * If the DisplayWidth or DisplayHeight is less than 800, use small size mode.
+ Also the size of the name widget was reduced from 500 pixels to 400 pixels
+ because in small size mode there was a gap on the right.
+ Changed the default font from fixed to helvetica_oblique14 to:
+ **-helvetica-bold-r-normal--14-*-*-*-*-*-*-*
+ helvetica_oblique14 is a font alias not on all R4 systems.
+ Curiously enough, the 17 point is not available on 75dpi systems
+ and the 18 point font is not available on 100dpi systems.
+ Thanks to Richard K. Lloyd for pointing these out.
+
+ * Minor hacks to work with R5 alpha. Had to add an event handler to the
+ boardWidget to get translations to work. This may go away with the real R5.
+ Added <Message>WM_PROTOCOLS: QuitProc() for R5 ICCCM compatibility.
+
+ * If the first character of the file is not `1' then the first line
+ of a game or position file is displayed as the name in a label widget.
+
+ * Added a PopUp dialog for getting file names.
+
+ * Modified the code to use the R4 routines rather than R3 compatibility.
+
+ * Changed the forwards/backwards/readgamefile code to allow a play to step
+ back and forth in a game. If he steps all the way to the beginning
+ he has to restart the game. If he gets into a mated position, same problem.
+
+ * Moved the man page from xboard.1 to xboard.man. This makes imake man page
+ installs work correctly. Thanks to Richard K. Lloyd for pointing this out.
+
+ * Corrected the queening code. XBoard was sending the wrong syntax.
+ It was sending for example h8(Q) when it should have been sending h8q.
+ Thanks to Paul Vaughan and Mike McGann for pointing this out.
+
+ * Added a lex parser for algebraic games. It should be easy to use the parser
+ for other interfaces such as the Microsoft Windows version.
+ It parses comments of the form [anything] and ! to the end of a line.
+
+Version 1.1 -- Mon Jan 7 14:46:03 PST 1991
+
+ * Roger Dubar, Konstantinos Konstantinides, Wolfgang S. Rupprecht,
+ Paul Scowen, Mvh Smidt and Kayvan Sylvan all helped immensely during
+ beta-testing.
+
+ * older non-ANSI versions of Sun compilers complain vociferously.
+
+ * the remoteShell resource was added for HP-UX systems
+ and other systems where the remoteShell isn't rsh.
+
+ * -iconic doesn't work properly. If XBoard is opened iconic then
+ iconifying it later with a keystroke doesn't work. I think
+ this is an Xt bug.
+
+ * For systems with smaller screens, XBoard can use smaller pieces,
+ and a smaller board. -bigSizeMode False uses a smaller set of pieces.
+ These are scaled versions of the large pieces. They look ok but could
+ be improved.
+
+ * getlogin() does not work in all cases.
+ It was replaced by getpwuid(getuid())->pw_name).
+
+ * Warning messages get displayed in the message box.
+
+ * Any button restarts a paused game.
+
+ * Kayvan Sylvan contributed a patch for ESIX.
+ It seems that select() on pipes is broken on his system. We declined
+ to incorporate his patch though, because it was a work-around for
+ something that was broken on one system, and selfishly, that system
+ was not my own. Nevertheless, it is likely that other System V users
+ on PC's may need to use this patch and it is is included as the file
+ ESIX.patch. To use it, type
+
+ patch xboard.c ESIX.patch
+
+ * Fixed a bug where hint didn't work. The local version of gnuchessr
+ had been hacked. The fix was to clone stderr and stdout for gnuchessr.
+
+ * Fixed a bug where a player could play after a game had been finished.
+
+ * The bitmaps have been pushed into the bitmaps directory.
+
+ * Substantially rewrote and simplified the Two Machine code.
+
+ * Added StrStr() because many systems don't have this ANSI function.
+
+ * Added keyboard equivalents. Added an iconify keystroke, C or c.
+
+ * Works with gcc now. gcc complained about casting float constants
+ as XtPointers.
+
+ * Detect if the visual doesn't support color. If so, run in monoMode.
+ An alternative would be to detect grayscale visual and use a collection
+ of gray user interface colors.
+
+ XBoard.clockMode: False
+
+ * For people who don't like or use chess clocks a clockMode switch
+ has been added. It is on by default. It can be turned off in the
+ .Xdefaults file with
+
+ * Added a declaration, xtVersion, which will quickly break on R3 Intrinsics.
+
+ * Hal Peterson contributed a new Imakefile.
+
+ * Rewrote DisplayClocks().
+
+ * Rewrote TwoMachinesPlay mode.
+
+ * Konstantinos Konstantinides added the -searchTime option.
+
+ * Substantially rewrote and simplified the clock code. If a game was paused
+ and then resumed, the clocks were out of sync.
+
+ * Fixed a bug in HandleUserMove() where the user could make a move while the
+ machine was thinking. The fix detects and ignores these moves. onMove
+ was not being used and was removed.
