(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 ". This is an alternative +to "edit", used only if the engine says "feature setboard=1". + +* Added new protocol command "ping ". The engine is supposed to +respond "pong ". 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 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. +
