1 ChangeLog for XBoard/WinBoard
2 * 06/12/2005: bugfix some more possible buffer overflows.
4 * 06/27/2004: added simple icsEngineAnalyze for xboard
6 * 06/26/2004: added icsEngineAnalyze for winboard: Analyze observe games
7 with a chessprogram on a Internet Chess Server (ICS)
9 * 02/12/2004: Bugfix ICS interaction console crashed while chess
10 engine starting and user type in some stuff. We are wait now to finish
13 * 02/11/2004: Winboard: Added color lines for the ics interaction
16 * 02/09/2004: Added mousewheel support for winboard. Play moves
17 backward and forward with the mousewheel.
19 xboard/WinBoard 4.2.7 -- Fri Nov 28 13:36:00 PST 2003 -- Tim Mann
21 * 11/26/2003: In WinBoard, setting the -debug flag now logs ICS output
22 to WinBoard.debug too. (This isn't needed in xboard because ICS
23 output already goes to stdout, so it's easy to capture along with the
24 debug output on stderr.) This was issue #280 in the ToDo file.
26 * 11/23/2003: Cleaned up some minor problems in cygwin.mak. Thanks to
27 Hans Werner Strube for the problem report.
29 * 11/23/2003: Updated the default list of chess servers in
30 winboard/defaults.h. Deleted two that appear to be dead and added a
31 new one that is active.
33 * 11/19/2003: Swapped icon_white.bm and icon_black.bm in XBoard.
34 Hopefully this will get them the right way around by default on more X
35 window managers. I wish I understood this better.
37 * 11/18/2003: Implemented a simple 32-bit random number generator for
38 WinBoard, replacing the Windows rand(), which ranges only up to
39 0x7fff. Formerly on Windows, only zippy.lines sayings that started in
40 the first 32767 bytes of the file could ever be used. This was issue
41 #505 from the ToDo file.
43 * 11/16/2003: The xboard man page and info files are now built from a
44 common set of texinfo source files, and the xboard man page now covers
45 cmail as well. Formerly, ever since the texinfo file was first
46 contributed to the project, it was separate from the man page and the
47 two files had to be updated in parallel, making for a maintenance
48 nightmare. To make combining the files possible, I took the Perl
49 script "texi2man" from the GNU Units project and added support for a
50 larger subset of the texinfo markup language. I then carefully
51 compared the old man page and old texinfo file to make sure the latest
52 and clearest words survived into the new combined texinfo file. It
53 would be great to merge in WinBoard's help file too, but that's a
54 larger project. It would have to be heavily conditionalized to
55 deal with differences in features between XBoard and WinBoard.
57 * 11/15/2003: Cleaned up and applied a small patch from Daniel
58 Mehrmann, to stop overly long PVs in thinking output from causing a
59 buffer overflow crash in backend.c.
61 * 11/5/2003: When a chess engine sends a "telluser" command (including
62 the cases where "tellall" or "tellopponent" acts like telluser), the
63 information now goes into a nonmodel popup that is automatically
64 dismissed when the user clicks anywhere on the board. This fix is
65 more significant on WinBoard, where formerly you got a fully modal
66 dialog that had to be dismissed by clicking on OK before anything else
67 could happen. The bug was issue #406 in the ToDo file.
69 * 11/1/2003: Removed email addresses from this file to reduce spam
70 load, as it gets linked to from the Web.
72 * 11/1/2003: Updated READ_ME and winboard/READ_ME.txt.
74 * Modified xboard and winboard makefiles to be able to build the
75 project in the new combined directory structure.
77 * Applied a small security fix to pxboard, from Martin Maeok.
79 * Fixed a bug in the game list dialog. The change in 4.2.6 to opening
80 games in text mode (meant to avoid getting extra \r's into comments)
81 caused a new bug in determining seek offsets when parsing a game file
82 to form the game list. Also, the change was incomplete; on some code
83 paths games were still being opened in binary mode. Thanks to Lenik
84 Terenin for reporting the offset bug. I've now gone back to always
85 using binary mode when reading game files, and I've fixed the comment
86 bug by adding code to remove \r's from parsed comments explicitly. I
87 still use text mode for writing game files so that games written by
88 WinBoard will have Windows-style line endings.
90 * Fix for minor bug in WinBoard installer. If you chose a non-default
91 destination directory, the default directory was still used for a
92 couple of unimportant things, namely setting the App Paths registry
93 keys (unused by WinBoard) and trying to copy the existing WinBoard.ini
94 file to WinBoard.old. I inherited this bug from the InstallShield 5
95 sample template. Thanks to "l.d." for noticing the incorrect keys.
97 * Patch from Chris Priest: when two engines are being run through rsh,
98 avoid reusing the same stderr port for both. I'm not sure why this
99 should be needed, but it's harmless, at least.
101 * Bugfix: The kludge to deal with old engines that give an error
102 message because they don't know the "st" command was too sloppy; it
103 could hit on an "st" substring anywhere in an error message. GNU
104 Chess 4 is the only engine I know of where the kludge was needed, so I
105 changed the kludge to match a longer, more GNU-specific string.
107 * Changed the WinBoard self-extracting installer to choose a unique
108 temporary subdirectory name within the Windows temp directory instead
109 of always putting wb-setup directly in temp. Besides being better
110 practice, this avoids the need to deltree wb-setup first, which
111 occasionally alarms someone who thinks that deltree is only used by
112 trojans to delete all your files. (Yes, I'm serious.)
114 * Fixed a bug where FICS-style "wild/0" strings were not parsed as the
115 proper wild type. The "/" was not being skipped.
117 * Fixed a WinBoard bug where temporary files created by game
118 copy/paste were being created in the root directory of the current
119 drive instead of the TMP directory and were not always deleted on exit.
121 * Fixed a small bug in winboard.c's ErrorDialog() function. Thanks to
122 "Ron" (no last name given). The bug might have caused a problem when
123 pressing OK or Cancel in an error dialog when more than one error
124 dialog was being displayed, but I'm not really sure.
126 * Removed a hack that worked around a bug in very old versions of
127 Crafty, where it would sometimes reply "illegal move" to a "."
128 command. The hack kept us from recognizing real illegal move messages
129 in analyze mode from engines that don't respond to the "." command.
130 Thanks to Fabien Letouzey for the report.
132 * Fixed a bug in the xboard version of GetDelayedEvent. It would
133 return the most recently scheduled event even if it had already fired.
134 This caused at least one visible error: in -ics -xreuse mode, starting
135 the engine again and seeing another "feature done=1" would re-run the
136 initialization code in InitBackEnd3, including the code that opens the
137 connection to ICS. The WinBoard version didn't have this bug. Thanks
138 to Bob Hyatt for the bug report.
140 * The promotion popup for ICC wild 26 (giveaway) now includes King.
141 Thanks to Fredrik Josefsson for the bug report.
143 * The first game in a file (or being pasted from the clipboard) can
144 now start with a bare move -- no PGN tags, no move number "1", etc.
145 Suggested by Shane Harrelson. One could imagine taking this farther
146 and accepting something like "e4 e5 1/2-1/2 d4 d5" as two games, but
149 * Bug fix: xboard didn't really accept a paste of multiple games,
150 contrary to what I wrote when adding the feature to WinBoard in
151 4.2.4. Now it works in both.
153 * Fixed generic start/end of game messages to work on chess.net, where
154 they put ratings in parens after the player names.
156 * Updated config.sub and config.guess to newer versions from
157 automake-1.4p5-2. This makes configure work with MacOS X + X11.
159 * Bugfix: when examining a game fragment on FICS where black plays
160 first, don't show two "(0:00.000)" times on the initial "none" move.
162 * If TestLegality is on and one of the engines makes an illegal move
163 in TwoMachines mode, it forfeits immediately. Formerly the game would
164 get stuck at that point and the engine that made the illegal move
165 would eventually lose on time.
167 xboard/WinBoard 4.2.6 -- Fri Feb 1 22:26:31 PST 2002
170 Another small bugfix release.
172 * Put in a small change from Alexander Mai to allow xboard to build in
173 an OS/2 EMX environment.
175 * Fix WinBoard-only bug where editing a PGN file with comments would
176 insert more \r characters before the \n after every Load/Save cycle.
177 For some unknown reason we were reading the files in "rb" mode but
178 writing them in "a" mode, so we kept the \r characters on reading and
179 added an extra one on writing. Fix: change the "rb" to "r". Thanks
180 to Joel (last name not given) for the bug report.
182 * Put the arguments to rsh/remsh in the right order for better
183 portability. Thanks to Michael Kalisz.
185 * FreezeUI is now implemented in WinBoard; it was previously only
186 implemented in xboard. This function prevents the user from entering
187 moves or other commands while we are waiting for an engine to
188 initialize itself. Implementing it fixes a bug where the user could
189 start a game (etc.) during feature negotiation. One of the symptoms
190 of this bug was that we could send "new" one or move moves *after* the
193 * Fixed some handle leaks (WinBoard only), including a nasty one that
194 leaked one handle per command sent to ICS. Thanks to several folks
195 who helped characterize the bug and tried to look for leaks.
197 * We now install and look for the info file in ${prefix}/share/info
198 instead of ${prefix}/info. The latter is still the default in
199 autoconf, but the former is currently used in Red Hat Linux and
202 xboard/WinBoard 4.2.5 -- Sat Dec 15 11:42:51 PST 2001
205 * Changed the bundled GNU Chess 5.02 in the WinBoard package to
206 include a much smaller book and to use much less hash table space by
207 default (8 MB transposition table, 0.5 MB pawn evaluation table). The
208 large book included with 4.2.4 made the WinBoard download too big for
209 some people, and the default hash tables were larger than the
210 available physical memory on some people's computers. I built the
211 small book by running Crafty's "small.zip" book line collection
212 through a Perl script that makes it look enough like real PGN games
213 that the GNU Chess book builder will accept it. The script and some
214 minor patches to GNU Chess 5 are available in the WinBoard source
215 distribution and at http://www.tim-mann.org/gnuchess.html.
217 * Fixed a bug in the code that deals with engines that complain that
218 "time" and "otim" are illegal moves. This was a new bug in 4.2.4.
220 * Revamped the implementation of ToStart in analysis mode. Formerly
221 there was some ill-conceived code that would try to get back to the
222 start of the game by doing a "new" command (and all the followup
223 commands that requires) while remaining in analysis mode. This is
224 problematic for engine authors to support, though it works with
225 Crafty. This code was trying to solve the problem of ToStart being
226 slow because the engine would try to start an analysis after every
227 "undo" command all the way back to the start. But ToEnd already had a
228 much better solution to this problem, and now ToStart does the same
229 thing: we exit from analysis mode and enter force mode instead,
230 make/unmake moves to get to the end/start of the game, and then
231 reenter analysis mode.
233 * Formerly, Zippy could try to start playing a game before the engine
234 was initialized; that is, during the initial timeout for protover 1
235 engines, or before "feature done=1" for protover 2 engines. We now
236 wait until the engine is initialized before connecting to ICS, which
237 fixes this in the common case. If you turn off engine reuse for
238 multiple games (that is, if you give the -xreuse option), there could
239 still be problems; see item 503 in the ToDo file. Thanks to Dieter
240 Buerssner for the bug report.
242 * Bugfix: All WinBoard versions since the merge with WinBoard Plus
243 (but not xboard) have had a bug in changing the PeriodicUpdates,
244 PonderNextMove, and ShowThinking options from the menu. The bug
245 mostly just caused changing these options during a game to not take
246 effect until after the next reset. For TwoMachines games, though,
247 changing PonderNextMove just before the game would take effect
248 immediately for the second engine but not until the next game for the
249 first engine. Thanks to Koundinya Veluri for the bug report.
251 * Bugfix: In 4.2.4, we sometimes got confused when trying to leave and
252 reenter analyze mode. One symptom was that Analyze File did not work.
253 Thanks to Igor Syry for the bug report.
255 xboard/WinBoard 4.2.4 -- Sun Dec 9 14:56:30 PST 2001
258 * WinBoard now includes GNU Chess 5.02 in place of GNU Chess 5.00.
260 * WinBoard's PasteGameFromClipboard will now handle a paste with
261 multiple games in it, popping up the game list dialog. xboard
262 already did this. Suggested by Robert Gerstman.
264 * We now use the "clearboard" command on ICC where appropriate.
266 * Bugfix: don't generate a bogus "variant normal" command to an engine
267 for the loadable ICC wild types that we internally flag as
268 VariantLoadable. Also clarified the message that Zippy sends when
269 declining such wild games -- it can't deal with the possibility of
270 loading an arbitrary position into the game. Thanks to Dieter
271 Buerssner for reporting the problem. It would be nice to be able to
272 actually play these wild types some day; presumably there would have
273 to be an option to either send "loadgame" with a specified position,
274 or to deal with an opponent sending it.
276 * If we get a holdings message from ICS when we thought we were
277 playing normal chess, we now try asking for a move list so that we can
278 find out from the header what's really happening. Formerly we guessed
279 bughouse in this case. Response to a comment from Gian-Carlo
282 * Fixed two longstanding bugs in the clock code. These affected only
283 play between a user and a local engine, or between two local engines,
284 not ICS play. (1) The last fractional second used by a player before
285 moving and virtually pushing his clock was being charged to his
286 opponent instead of to him. (2) The time and otim commands were being
287 sent to an engine before the (buggy) fractional second update was
288 done. The second bug was pretty harmless in itself, but the first one
289 was serious. Many thanks to Peter Rosendahl for carefully diagnosing
290 and reporting these bugs!
292 * Changed WinBoard timestamp key. Nothing is changed other than the
293 key and a recompilation. ICC may phase out the old key soon; if they
294 do, you'll need to use the timestamp.exe from WinBoard 4.2.4 or later
295 to connect to chessclub.com.
297 * Fixed an xboard-only bug where most dialogs would not take keyboard
298 input unless the mouse was actually over the dialog, even if the
299 dialog window had focus. Thanks to Jason Varsoke for the bug report.
301 * Bugfix; Remember to send time and otim commands to engine before
302 sending playother. Thanks to Bob Hyatt for the bug report. Also
303 fixed a bug where time and otim were sometimes sent even with feature
306 * Added small patches from Wilkin Ng that are meant to fix a crash in
307 CopyGameToClipboard and a "can't unlock clipboard memory" error in
308 PasteTextFromClipboard, under Windows 2000.
310 * Changed cygwin.mak to not use -mno-cygwin. In other words, it now
311 uses cygwin1.dll instead of the mingw libraries. This works around
312 bugs in fileno() and stat() that I encountered in mingw. (fileno
313 seems to always return 0. stat fails because the library routine uses
314 a different definition of struct stat than the header files provide.)
315 Thanks to Robert Gerstman for reporting the symptoms these bugs caused
316 when WinBoard was compiled with Cygwin.
318 * Added -showButtonBar option. This lets you delete the << < P > >>
319 buttons and thus widen the message widget a bit.
321 * Added code to address a very obscure bug. If an engine dies and
322 needs to be restarted while in one of the analyze modes, it was not
323 getting put back into analyze mode. This bug should not really ever
324 have gotten tickled unless reuse was turned off and the engine sends
325 game end commands (such as 1-0) when a game ends by rule while in
326 analyze mode. The next version of the protocol spec will say that
327 engines should not do that, but version 2 and earlier didn't address
330 * We now use the FICS "iset ms 1" feature to get times in ms instead
331 of seconds. Thanks to DAV for email telling me about this feature.
333 * Changed clock display to show tenths of seconds for 9.9 seconds and
334 less, instead of 0.9 seconds and less as before.
336 * It has been discovered that Zippy can play simuls on ICC (but not on
337 FICS). If you arrange for Zippy to send the ICC command "simulize" in
338 the -zippyGameStart string, it will accept additional games while
339 playing. Zippy will use the same engine for every game, so whenever
340 it switches opponents, the engine's state will be reset with the "new"
341 command. This will of course weaken its play, so don't enable simuls
342 if you want your engine to have the highest possible rating. Zippy
343 was never designed to work with simuls; it just works by accident, and
344 it hasn't been tested much. So please report any bugs you notice, but
345 don't expect them to be fixed rapidly. Thanks to Paul McGuire for
346 noticing that this works.
348 * Bugfix: Suppress the direct command to engine popup if there is no
349 engine. In WinBoard this case used to cause a crash. Thanks to
350 "Dargon" for the bug report.
352 * Bugfix: formerly we did part of the engine initialization for the
353 very first game too soon, before feature negotiation. One result of
354 this is that engines would never get the "ics" command for the first
357 * Lengthened timeout to detect protocol version 1 chess engines to 10
358 seconds. This should reduce problems with protocol version 2 engines
359 that are slow to initialize missing the timeout and not getting a
360 chance to send their feature commands before the first game starts.
362 * Klaus Friedel says that adding a short sleep to WinBoard after
363 starting a new chess engine solves a problem that occurs under Windows
364 2000, in which engines sometimes don't see the initial command(s) from
365 WinBoard and hang. I don't understand how that can happen, but the
366 sleep is harmless, so I've put it in. Others have also reported what
367 may be the same problem, so hopefully this will fix it for them too.
369 * Bugfix: editing the Result field in EditTags will no longer cause a
370 later crash. Thanks to DAV for a clear bug report that let me
371 reproduce the problem.
373 * ICC wild 28 is now recognized as shatranj, but it is not supported.
374 You might be able to play it by turning off Test Legality.
376 * Formerly we would always turn off "feature time" if the engine
377 printed an error message with the string "time" or "otim" in it; now
378 we do that only if the message comes before the engine makes its first
379 move. This change is useful because some engines spew a lot of bogus
380 error messages about commands they don't fully parse, so something
381 like "result 0-1 {White lost on time}" could generate such a message.
382 Engines shouldn't do that, but if they do, mysteriously turning off
383 "feature time" is not a good way to react.
385 * Fixed an infrequently occurring Zippy bug: formerly, resuming from
386 adjournment by position (that is, with GetMoveList turned off) or
387 starting/resuming a wild game (nonstandard starting position) would
388 try to set up the position without putting the engine into force mode
389 first. That was probably tolerated by most engines, but if the
390 position was black-to-play and the engine hadn't set feature
391 setboard=1, then the fake "a2a3" move (which we use as a kludge to get
392 black to be on move before sending the edit command) would appear to
393 be a real move, and the engine might reply to it! This bug could also
394 be seen when trying to use Zippy to play a simul -- something that
395 Zippy was never designed to support, but which seems to mostly work
396 anyway. Thanks to Paul McGuire for sending a WinBoard.debug file that
397 showed the bug occurring. Some other cases of resuming adjournments
398 or starting games from nonstandard positions may have been broken too;
399 I think I've straightened out the problems.
401 * Agreeing to a draw in the human vs. local engine case formerly did
402 not work if the human offered first; now it does. A human's
403 unsolicited offer is considered valid until he makes another move.
404 Thanks to Bruce Moreland for the bug report.
406 * Bugfix: We used to look for just "fr" in Event tags or strings from
407 ICSes to recognize Fischer Random games. This caused a lot of false
408 matches. Now we look for "wild/fr" instead, which is what FICS uses.
410 * Bugfix: Clicking on a move in the MoveList window only updated the
411 displayed position; if a chess engine was active, its state was not
412 updated. Thanks to Alejandro Dubrovsky for the bug report.
414 * Bugfix: The "resign" command from engine to xboard formerly did not
415 work in ICS (Zippy) mode.
417 * Bugfix: Formerly we would register a garbage premove if the user
418 clicked on a piece, then clicked on an edge or outside the board. Now
419 such an errant click is ignored.
421 * Bugfix: GameEnds would send "exit" to an engine in analyze mode even
422 if we did not actually want to leave analyze mode.
424 * Bugfix: "feature pause" was being rejected. We don't currently use
425 it, but that is no reason to reject it. Thanks to Gian-Carlo Pascutto
428 * Bugfix: when "partner" needed to be sent both to ICS and the engine,
429 Zippy was erroneously sending the ICS prefix character to the engine
430 too. Thanks to Gian-Carlo Pascutto for the bug report.
432 * Zippy now declines challenges when the engine is not yet ready to
433 play again, instead of ignoring them. This is needed so that the
434 server will let the opponent repeat the challenge. It might be better
435 to remember such challenges and accept them when the engine is ready,
436 but that would be a bit more complicated to implement.
438 * Bugfix: Zippy's emotes didn't work on FICS because there, "i" is a
439 built-in alias for "it", not a real command. So sending "$i foo" gave
440 an error message instead of doing "it foo". We now leave out the
441 alias-suppressing prefix for emotes.
443 xboard/WinBoard 4.2.3 -- Mon Feb 19 19:55:05 PST 2001
446 * Bugfix: The error message "Variant X not supported by gnuchessx"
447 formerly could pop up even in -ncp mode.
449 * Fixed an xboard bug in premove highlighting. If you had
450 HighlightLastMove turned on, premoves got highlighted in
451 highlightSquareColor (yellow) instead of premoveHighlightColor (red).
453 * Modified premove again. Now we are back to displaying the move
454 locally immediately after sending it to the server, as in versions
455 prior to 4.2.1. This is good because it lets you register your next
456 premove sooner. As a better fix to the problem that the change in
457 4.2.1 had been trying to address, we now suppress animating the
458 opponent's move if you have a premove reply pending. However, it's
459 probably still a good idea for you to turn off AnimateMoves entirely
460 if you are trying to play extremely fast games.
462 * Removed an erroneous patch that left zombie chess engines around
463 when both sigterm and reuse were turned off. (Bug was in xboard only,
466 * Bugfix: loading a game with autostepping did not work for games with
467 PGN result "*" (unfinished). This bug was introduced in 4.1.0, caused
468 by some outdated code that was supposed to leave you in EditGame mode
469 after loading an unfinished game. I fixed this, and also changed it
470 to leave you in EditGame mode after loading *any* game, but without
471 changing the tags to say it's an edited game. It's not really clear
472 whether that is the best thing is to do here -- ideally, perhaps, the
473 tags should change to say "edited game" if you actually make any
474 changes, but that is harder to make work.
476 xboard/WinBoard 4.2.2 -- Tue Feb 6 20:00:00 PST 2001
479 * Fixed a problem introduced in 4.2.1. In -zippyPlay mode, 4.2.1
480 started sending the initString immediately after the old game ended,
481 but then when the next game started, it would still send "force" and
482 another initString. Another problem was that the first initString put
483 the engine out of sync with the displayed board position, though that
484 might not usually have been noticeable. This is now changed to do a
485 full Reset at the end of the previous game, and avoid doing a Reset at
486 the start of a new game if we are still in BeginningOfGame mode.
488 * Fixed some limitations in -zippyPlay mode. The engine was not being
489 fed the moves or history of games that were displayed but not being
490 played, so it would get confused if you tried to do something like
491 examine a game, then enter EditGame mode from somewhere in the middle
494 * Made a small change so that cygwin can compile xboard for Windows
495 (an X server is required to run it). Thanks to Volker Zell. Most
496 people would probably prefer to run WinBoard on Windows, however; note
497 that cygwin could already compile WinBoard.
499 * Added some missing documentation to engine-intf.html: It is okay to
500 send "feature done=0" even before you receive the xboard and protover
501 commands, if this is needed to give your engine enough time to
502 initialize. See engine-intf.html for more discussion.
504 * Bugfix: "feature done=0" did not work for the second engine; now it does.
506 xboard/WinBoard 4.2.1 -- Sat Feb 3 19:52:26 PST 2001
509 * Bugfix: in Zippy mode with feature san=1, the elapsed time was being
510 sent to the engine after the SAN move; for example, "e4 (0:01)" was
511 sent instead of just "e4".
513 * It seems that scroll wheel mice with incompletely installed software
514 (under Windows 95, at least) can send repeated middle button up events
515 when the wheel is turned. Moved QuickPaste from middle button up to
516 middle button down to avoid problems with this.
518 * A premove is now sent *before* the opponent's move that it replies
519 to is animated. The premove itself is no longer displayed (or
520 animated) when sent; instead, it is displayed when the chess server
521 echoes it back as a board update.
523 * Bug fix: in -xreuse mode, xboard was only sending command line
524 arguments to the engine the first time it was started. (WinBoard
525 didn't have this bug.)
527 * In -zippyPlay mode, we now initialize the chess engine for a new
528 game immediately after the old game ends. (In -xreuse mode, this
529 means starting a new engine process; in the default -reuse mode, it
530 just means sending "new".) If the engine supports ping, we don't
531 accept challenges until the "new" has finished. This should help
532 avoid losing time (re)initializing the engine after the game starts.
534 * We now handle the new FICS field in style 12 that says whether the
537 * whiteFlag and blackFlag are now reset whenever an ICS board image
538 arrives, giving autoflag a fresh chance to work.
540 * Suppressed "geometry error" debug messages unless -debug flag is given.
542 * Bugfix: avoid core dump on Solaris with -debug flag, caused by
543 passing NULL to a %s format in GameEnds.
545 * Added -firstProtocolVersion and -secondProtocolVersion. This will
546 allow use of extremely broken engines that hang or die when given the
547 "protover 2" command. It should be rarely if ever needed.
549 * Zippy now strips highlights from player names in the Creating
550 message; previously the ratings would not be extracted from this
551 message properly if you had set the highlight variable.
553 * Bug fix: Zippy with -zp but not -zt used to be fooled by false
554 partner tells inside channel tells; e.g.:
555 Garf(24): Garf (your partner) tells you: sit
557 * Bug fix: when an engine reported its name with the new "feature
558 myname=" command, we had been putting just that name into the window
559 title even when in TwoMachines mode.
561 * By default, WinBoard no longer uses the new feature introduced in
562 4.2.0beta of keeping the ICS menu, ICS server list, and lists of chess
563 engine command lines in separate files; instead, the lists are back in
564 the winboard.ini file. This gets rid of some problems where the
565 separate files could not be opened because the working directory was
566 not set to WinBoard's installation directory.
568 * WinBoard command lines and ini files now have another optional
569 syntax for quoting an option value. All characters within { } curly
570 braces are interpreted literally except for '}' itself. SaveSettings
571 now uses this syntax for string values that contain a backslash or
572 newline and do not contain a '}'. This should address the problem
573 that the separate .ini files had been meant to fix; engine command
574 line lists can now be written without \-escapes.
576 * Fixed three bugs in relaying moves between engines in TwoMachines
577 mode: an engine would be sent SAN if the *other* engine had set
578 feature san=1, a relayed SAN move did not end with a newline, and
579 feature usermove was not implemented for relayed moves.
581 * Fixed several bugs in exiting: File/Exit would sometimes hang;
582 timestamp/timeseal would not get killed off; an engine crash would
583 cause error messages to be printed recursively until stack overflow.
585 * Fixed a bug in the code to detect which ICS is in use and adapt to
586 it; the chess.net case was broken.
588 * Removed the leading alias-suppression character when sending a move
589 to ICS, because it seemed to break accuclock on chess.net.
591 * Fixed a bug where a FICS prompt like "10:01_fics%" would be matched
592 as finger note number 10, causing a problem detecting when the user is
595 * Added tellicsnoalias command to protocol.
597 * Changed st command in protocol back to old behavior.
599 * Added done=0 feature to protocol, to lengthen initial timeout.
601 * Added missing -colorSeek command line option to xboard. (Was
602 present in WinBoard.)
604 * Bug fix: setting feature reuse=0 was not working.
606 xboard/WinBoard 4.2.0beta -- Sat Dec 16 16:34:56 PST 2000
609 * Setting -searchTime no longer turns off -clockMode. Note that when
610 -searchTime is set, some engines may search for the lesser of
611 searchTime and the amount of time their normal clock management would
612 dictate, while others will disable their normal clock management and
613 always search for exactly searchTime.
615 * Fixed WinBoard bug where on Windows 2000 (and maybe Windows 98) the
616 ICS Interaction window would scroll back to the top whenever it filled
617 to capacity and WinBoard trimmed some text off the top.
619 * Changed xboard dragging so that the center of the dragged piece is
620 forced to be over the mouse cursor. (WinBoard dragging already worked
621 that way.) This should avoid confusing cases when you start a drag
622 with the mouse near the edge of a square -- formerly most or all of
623 the piece could be over one square but the mouse cursor over another.
626 * Added move list window for xboard. Code contributed by Manuel
627 Hoelss and re-hacked a bit by me. Performance of this window is poor,
628 because the implementation regenerates the entire window contents
629 whenever anything changes. It's hard to avoid this when using the
630 Athena List widget, though we could be a little smarter and notice
631 when the current move number has changed but the move list has not.
632 There are also several drawing problems caused by bugs in the Athena
633 Form and List widgets. The window should not really allow a
634 horizontal scroll bar, but the bugs are much worse if I turn it off.
635 In both Xaw and Xaw3d, the List widget tries to resize itself when
636 XawListChange is called, even if you tell it not to; and what's worse,
637 if the widget cannot resize itself to be large enough to avoid
638 clipping any of the list item, it does not change the list! Arrgh.
639 On top of that, the Xaw Form widget is very buggy in XFree86 4.0.1
642 * The OK button in the WinBoard startup dialog is now simply disabled
643 if none of the radio buttons is selected, instead of bringing up an
644 error dialog. Suggested by Ted Milbaugh.
646 * Used ping to address the worst of the race conditions in the
647 protocol. Now if an engine supports ping, we ping it after sending
648 the "new" command and after trying to place it in force mode at the
649 end of a game. When a ping has been sent and the corresponding pong
650 has not yet come back, we (1) ignore or undo any moves the engine
651 sends, (2) ignore game end messages (such as "offer draw", etc.) from
652 the engine, (3) ignore thinking output from the engine, (4) delay
653 starting the next game if in -matchGames mode, (5) in -zippyPlay mode,
654 respond to challenges with a polite message to try again soon instead
655 of accepting them. There are a few more things that should be done
656 (and item 5 might not be quite what we want), but it's hard to fit
657 them all into the existing code.
659 * Patched the version of GNU Chess 5.00 included with WinBoard to
660 support protover, feature, setboard, and ping, and to fix some minor
661 bugs. See gnu500+.patch.
663 * Changed the GNU Chess 4 kludges for missing "st" and "sd" commands
664 to be invoked only if the engine gives an error message for "st" or
665 "sd", and to always use protocol commands instead of engine
666 command-line options. See "Idioms" in engine-intf.html.
668 * Added new protocol command "protover 2" to tell the engine what
669 version of the protocol is in use. Version 2 is still compatible with
670 old engines; see engine-intf.html.
672 * Add new protocol command "feature ..." The engine can send this in
673 response to the protover command command, to say what extended
674 protocol features it would like to enable, etc. xboard responds
675 "accepted F" or "rejected F" for each feature F that is set. See
678 * Added new protocol command "setboard <fen>". This is an alternative
679 to "edit", used only if the engine says "feature setboard=1".
681 * Added new protocol command "ping <msg>". The engine is supposed to
682 respond "pong <msg>". This gives us a tool to fix some race
683 conditions in the protocol, but it is not used to the fullest yet.
685 * Added new protocol command "tellopponent". This will do a "say" if
686 you're on a chess server in Zippy mode, or pop up an information
689 * Added new protocol command "tellall". This will do a "kibitz" if
690 you're on a chess server in Zippy mode, or pop up an information
693 * Added new protocol command "tellothers". This will do a "whisper" if
694 you're on a chess server in Zippy mode, or do nothing otherwise.
696 * Changed the WinBoard /icsNames, /icsMenu, /firstChessProgramNames,
697 and /secondChessProgramNames options to accept a filename preceded by
698 "@", meaning to find the value in the file. Changed the defaults to
699 use this feature, with filenames icsnames.ini, icsmenu.ini, fcp.ini,
700 and scp.ini. This should make it easier for users to edit the values,
701 since one less level of quoting is needed, and each value is in its
702 own file, not mixed into winboard.ini. Those who upgrade from an
703 older winboard version and already have a winboard.ini file will not
704 automatically have these values moved to a file; that has to be done
707 * We now strip .exe from engine names for "name" command, tags, etc.
709 * Allowed WinBoard input widget to hold more than one line. You can get
710 a newline into the widget with copy/paste or with Ctrl+Enter.
712 * Fixed an xboard bug where the [P] button would appear in the
713 opposite highlight state from what it should be after being pressed.
715 * We now use the "/" or "$" alias suppression feature on the chess
716 servers, to avoid problems if the user inadvertently aliases a
717 needed command to something else.
719 * Changed the method used to deiconize xboard in AutoRaise and cmail.
720 This may fix bugs under some window managers where after
721 deiconization, the board window was mapped but nothing was drawn
724 * Preliminary, partial support for playing several chess variants
725 against a local engine or editing variant games. The -variant option
726 must be given on the command line or WinBoard startup dialog; there is
727 no menu. The current variant is not displayed (except in the
728 Tags/EditTags window). Many variants will not work quite right even
729 if the engine supports them; see item 326 in the ToDo file for
732 * Added a workaround to detect the variant type when examining a
733 scratch wild game on an ICS.
735 * Fixed two cases where "variant" command should be sent to the engine
736 when necessary but was not: loading a game from a file and restarting
737 a dead engine. Thanks to Gian-Carlo Pascutto.
739 * Added missing support for FICS games that start from a bsetup position
740 with Black moving first.
742 * Fixed a bug in loading a file from the game list window while in
743 Analysis or AnalyzeFile mode. This now leaves us in AnalyzeFile
744 mode, analyzing the new file.
746 * Fixed a bug in loading games with a comment before the first move.
748 * Fixed a bug in handling LoadGame (or -lgf) with -td 0.
750 * Added a command line option to select an initial minor mode from the
751 Mode menu. This should satisfy requests from a couple of users with
752 special applications.
754 * Fixed a problem where some things in WinBoard's General Options
755 dialog box were grayed out at the wrong time.
757 * We look for a few messages from the chess engine pipe that are
758 intended to catch problems starting an engine via rsh, such as "No
759 such file". Moved code so that these strings won't match until other
760 protocol messages have been looked for, and documented the messages in
763 * Fixed the WinBoard bug that sometimes made the console input box
764 white-on-white even when not in password-entry mode.
766 * Small changes to WinBoard to be compilable with the latest Cygwin
767 net release (as of 10-16-2000). Thanks to Mark Schoenberg.
769 * Recompiled GNU Chess 5.0 for WinBoard with the latest Cygwin net
770 release (as of 10-16-2000). Also rebuilt the book just to be sure,
771 since I had one bug report about it. It came out identical and seems
774 * Added messages for some common InstallShield errors instead of just
775 printing InstallShield's stupid error code numbers.
777 * Added -firstComputerString and -secondComputerString, allowing you
778 to suppress or change the command that is sent to a chess engine when
779 its opponent is another computer.
781 * Added "configure --with-Xaw3d" to allow use of Xaw3d widgets instead
782 of Xaw widgets in xboard. Thanks to Johnny C. Lam of the NetBSD
783 project. I've left Xaw as the default because Xaw3d is too ugly.
785 * The version of the Xaw Form widget released in XFree86 4.0.1
786 (X11R6.4.3) has a bug that causes xboard to display the button bar
787 on top of the message widget. I've reported the bug and have
788 installed a kludge workaround into xboard.
790 xboard/WinBoard 4.1.0 -- Sun Sep 17 17:30:14 PDT 2000
793 * Merged Winboard Plus 4.0.8 from Mark Williams into xboard
794 source pool. Status of Winboard Plus features in xboard:
796 - White pieces now have borders, but the implementation is
797 completely different from WinBoard's; see below.
799 - Options menu not changed, probably won't be.
801 - Copy&paste support working, using Mark's changes to backend.c, Ben
802 Nye's changes to xboard.c for FEN positions, and some code of my
803 own in xboard.c for PGN games.
805 - Premove hooked up and working. No pre-first-move, though.
807 - ICS Alarm hooked up and working.
811 - PGN Training mode hooked up and working.
813 - Improved menu item enable/disable working.
815 - Improved >> button working.
817 - Auto activate board working. I changed this to be optional; you
818 might not always want it, especially in Zippy mode.
822 - Documentation updated.
824 * Fixed more colorization bugs. Commands like "message foo tells you:
825 xxx" and "tell 33 tells you: xxx" will no longer generate bogus
828 * Added low-tech sound support to xboard, by invoking an external
829 program on a filename for each sound to be played.
831 * ICC wild 27 is now recognized as VariantAtomic, and it sets the
832 "ignore check" flag, but is not otherwise supported.
834 * Converted the piece bitmaps from .bm to .xpm for use with xboard's
835 xpm support. (An .xim version was not created.) Wrote a shell script
836 using ImageMagick to do the conversion and to bucket fill from
837 coordinate 0,0 with the background color. Used xpaint by hand to
838 clean up a few pieces where background color "leaked" into the inside
839 or didn't flow all the way around the outside, then a sed script to
840 fix up color names and bitmap names in the xpaint output. If any more
841 sizes are added later, they should be straightforward to convert with
842 reference to the existing scripts. With this conversion, not only do
843 the white pieces now have dark borders, but (unlike with WinBoard) the
844 light details on the black pieces are opaque.
846 * If the XPM library is found when building xboard, the new xpm pieces
847 are compiled in as the default. External bitmap (or xpm) pieces can
848 still be used by giving the -bitmapDirectory (or -xpmDirectory)
849 option. If the XPM library is not found, the old bitmap pieces are
850 the default. In this case external bitmap (or xim) pieces can be used
851 by giving the -bitmapDirectory (or -xpmDirectory) option. There is no
852 way to compile in xim pieces.
854 Winboard Plus 4.0.8 -- Sat Aug 5 15:51 PDT 2000
859 * Main menu now visible in Win NT. Thanks to Microsoft for creating a
860 compiler which auto-mutilates the WinBoard.rc file so that the menu is
861 displayed under Win 98 but not Win NT. I fixed the problem by hand editing the
864 * "Reset game" now works properly when invoked from Analysis mode when two
865 engines are present. Correction of bug introduced in Winboard Plus. Thanks to
866 Mogens Larsen for reporting the bug.
868 * Pasting a FEN position with Black to move now works in all modes.
869 Thanks to Mogens Larsen for reporting the bug.
871 * Added gnuchess.dat to the distribution and a couple of text files that were
874 *** Merged in the following changes from Tim Mann:
876 * Bugfix: Highlights would sometimes not be taken down, at least in
877 xboard. The problem is that SetHighlight works in chess coordinates,
878 not view coordinates, so if flipView has been toggled since the
879 highlight was put up, it gets taken down from the wrong square. Fixed
880 by being careful to call ClearHighlights before toggling flipView, not
883 * Bugfix: HighlightLastMove would sometimes highlight square a1 after
884 a FICS "tomove black" command.
886 * Bugfix: a move list with initial position that has black to play was
887 not being handled correctly.
889 * Removed "decline abort" and "decline adjourn" commands from Zippy.
890 The syntax is changing on FICS, and Zippy really doesn't have to
891 explicitly decline the requests anyway; it's sufficient to not accept
894 * ICC wild 26 is now recognized as VariantSuicide (the FICS name; ICC
895 calls it "giveaway").
897 * Bugfix: PGN games with black to move in the initial position weren't
898 being legality checked correctly. I think this was introduced in
899 4.0.6 when I fixed a different PGN bug. Thanks to Mark Williams for
900 spotting the bug and suggesting a fix.
902 * Bugfix: the initial "name(" of a kibitz wasn't being colorized.
904 Winboard Plus 4.0.7 -- Thu May 12 17:57 PDT 2000
907 * New white pieces with black borders.
909 * Major overhaul to Options menu. New dialogs for setting General Options,
910 Board Options, ICS Options, Sounds, Fonts, Colors.
912 * Clipboard support for PGN game scores and FEN positions.
914 * Optional ICS Premove with user-specified first moves for White and Black.
916 * New sound events: ICS Win, ICS Loss, ICS Draw, ICS Unfinished, ICS Alarm.
918 * New auto-flip option when playing against a chess program.
920 * Added PGN Training mode.
922 * Certain menu options now disabled while program is thinking.
924 * ">>" button now always goes to the end of the game.
926 * In ICS mode, the board is automatically activated at the start of a
929 4.0.7 -- Sun Mar 5 17:17:49 PST 2000 Tim Mann
931 * Fixed a nasty bug in parsing ICS game histories that was introduced
934 4.0.6 -- Fri Mar 3 16:20:11 PST 2000 Tim Mann
936 * Fixed bugs in Zippy's code for responding to messages sent with the
937 ICS "message" command.
939 * Fixed bugs where xboard could still create dialogs partially off the
940 top of the screen. Fixed unwanted interactions between initial sizes
941 and positions of various unrelated xboard dialogs. Deleted
942 borderXoffset and borderYoffset resources.
944 * Fixed restoring the xterm name on exit to work in more cases.
946 * Small fix to the WinBoard self-extracting installer: when it starts
947 up, it now always deletes any old wb-setup directory left over from a
948 previous installation. Formerly this worked only on Windows 95/98, so
949 on NT the self-extractor would sometimes stop and ask the user whether
950 it was OK to overwrite the old wb-setup files.
952 * Modified WinBoard to be compilable with the free Cygwin tools
953 available from http://sourceware.cygnus.com/cygwin/. Based on work by
954 Mark Schoenberg. (His mods were enough to get WinBoard through the
955 compiler, but a few things were broken along the way, so I reworked them.)
957 * Merged changes from Don Fong to make WinBoard compilable with
958 Borland C++ 4.5. I do not have Borland C++ and am unable to test with
959 it, but I did make sure the changes don't stop it working with MSVC++
962 * Forbade entering TwoMachines mode from MachineWhite or MachineBlack
963 mode when machine is on move. This used to confuse the engine and
964 cause problems, because when we try to get the engine to stop, it
965 might make a move first, and it might not do that immediately.
967 * Variant classification now deals with new ICC wild 25, classifying
968 it as "3check". Also, we are now conservative about new wild numbers
969 we don't know about, classifying them as "unknown" instead of
972 * Replaced bad GNU Chess 5.00 book in WinBoard distribution with a
973 correct one. 1.e4 now no longer takes GNU Chess 5.00 out of book!
974 Thanks to Pete Galati.
976 * Made move parser accept and ignore nonstandard ep suffix on PGN moves,
977 e.g., "exf6ep" or "exf6e.p."
979 * Fixed bugs in parsing PGN files starting with no move number, or
980 with a move number other than "1." (including "1..."). Thanks to
981 Michael Soulier and Stefan Zipproth for example PGN files
982 demonstrating the bugs.
984 * Changed InitComboStringsFromString to not modify the input string;
985 this caused an exception when WinBoard was compiled with MSVC++ 6.
986 Thanks to Bert Tuyt for the report.
988 * In WinBoard, dragging a piece off the edge of the board without
989 releasing the mouse button no longer instantly aborts the move. You
990 still must release the mouse button inside a square to complete a
991 move, but you can now drag off the edge and come back inside.
993 * WinBoard bugfix: If you went into EditGame or EditPosition mode
994 while observing or playing an ICS game, and a new move came in
995 (snapping you back to ICSClient mode) while you were dragging a piece
996 around, the drag state would not be reset, causing the piece you were
997 dragging to remain on the board wherever you dropped it. Thanks to
998 David Brinegar for the bug report.
1000 * WinBoard bugfix: If you moved or resized the board while your
1001 opponent was moving, and you had AnimateMoving on, his move would not
1002 be displayed until after your next move. Thanks to DAV for reporting
1003 the bug repeatedly until I finally understood it.
1005 * Added a Zippy "farewell" feature; see zippy.README.
1007 * Fixed a bug (xboard only) in processing -zippyReplayTimeout on the
1008 command line. Thanks to Steve Beer for the report and patch.
1010 * Send "computer" command to both sides in TwoMachines matches.
1012 * Fixed a Y2K bug in Evan's cmail code! Thanks to Brian Mays for the
1015 * Bugfix: Initialize variant field of GameInfo struct in gameinfo.c.
1016 This could cause crashes in LoadGame. Thanks to Andrzej Nagorko.
1018 * Fixed several pattern matching problems: Finger notes and formula
1019 vars no longer get replied to by zippyTalk or colorized. Channel
1020 tells by players with many titles are now colorized fully, and
1021 zippyTalk handles channel tells by such players correctly. The shout
1022 "--> foo(99): bar" no longer gets colorized as a channel tell. Code
1023 is cleaned up a bit, and autocomment capture now uses the same
1024 criteria as colorization.
1026 * xboard fix: Enter key now closes error popups as in WinBoard.
1027 Especially nice for the "Exiting: Connection closed by ICS" popup.
1029 4.0.5 -- Tue Dec 7 10:30:40 PST 1999 Tim Mann
1031 * Added missing documentation of SIGTERM usage into engine-intf.html.
1033 * Bugfix: New -zippyReplayTimeout option was misspelled in WinBoard as
1034 -zippyReplyTimeout. Thanks to Francesco Di Tolla.
1036 * xboard -ics now restores the xterm's original title upon exit, at
1037 least if $WINDOWID is set.
1039 * Bugfix: -matchGames mode wasn't terminating properly. Final score
1040 popup would come up twice and engines would not be killed off. Thanks
1041 to Frank Quisinsky for the bug report. Bug was introduced in 4.0.4.
1043 * Bugfix: "tell 50 foo shouts: bar" no longer gets colored as a shout;
1044 similarly for "...s-shouts:" and "...c-shouts:". Thanks to David Lee
1047 4.0.4 -- Fri Dec 3 17:51:27 PST 1999 Tim Mann
1049 * Bug fix: formerly if you invoked SaveGame from EditPosition mode
1050 with black to play, the position was not saved properly. As a quick
1051 fix, SaveGame now takes you out of EditPosition mode before saving.
1053 * Changed -matchGames to keep track of the score (won-lost-drawn) and
1054 display it in the banner. The final score is displayed in a modal
1055 popup before the program exits.
1057 * Changed "Connection closed by ICS" to display in a model popup
1058 before the program exits.
1060 * Added -popupExitMessage option, default on. Setting this to false
1061 suppresses the modal popups that you sometimes get just before
1062 xboard/winboard exits -- both the two new ones listed above and the
1063 existing Fatal Error popup. This is useful when running Zippy
1064 unattended from a shell script (or .bat file) that loops and starts a
1065 new copy after a time delay when there is an error.
1067 * In xboard, added missing support for WM_DELETE_WINDOW to all
1068 windows. This makes xboard a better citizen, and is much needed with
1069 the newer X window managers that put an [X] button on every window and
1070 bind it to "kill application" if the applicationd does not support
1071 "delete window". We can't allow xboard to be thoughtlessly killed,
1072 since that leaves the chess engine running in the background.
1074 * We now avoid positioning tops of xboard dialog boxes offscreen.
1076 * zippy.lines can now use the caret ('^') character as an inter-saying
1077 separator. You no longer need to dig up a text editor that can put NUL
1078 ('\000') characters in text files.
1080 * Bugfix: In traditional chess clock mode, White now gets time added
1081 to its clock as soon as it makes time control. Previously both White
1082 and Black got their time added only when Black made time control,
1083 which would cause some engines to make their 41st move as White too
1084 quickly, thinking they were low on time.
1086 * The zippyAcceptOnly feature no longer sends a decline command or
1087 a tell. Thus you can use it to put Zippy into a manual accept mode.
1089 * Bugfix: "tell 50 foo tells you: bar" no longer gets colored as a
1090 personal tell; similarly for "...whispers:" and "...kibitzes:".
1092 * WinBoard no longer blanks the message line when you start a new
1093 move, unless there was an error message there from the previous move.
1095 * WinBoard now never puts the white piece drop menu on the middle
1096 mouse button. Both colors are always on the right button. Windows
1097 users often don't think to look for a middle button menu, or don't
1098 really have a working middle button despite what Windows says.
1100 * Guest login handles on ICC are now parsed again; an ICC wording
1101 change had broken this feature.
1103 * Autodetect when the engine does not support the "draw" command and
1104 don't relay the command to it in that case. Needed because sending an
1105 unsupported command to GNU Chess makes it move immediately, so people
1106 could make Zippy move without thinking by continually offering a draw.
1107 Thanks to Frank Walker for the problem report.
1109 * Small changes based on code from Robert Jurjevic: The WinBoard
1110 analysis window can be minimized (though not to the taskbar). The
1111 WinBoard ICS Interaction window will autoscroll if you drag the mouse
1112 above or below the window while selecting, and password entry mode
1113 leaves the entry line as the background color instead of using 75%
1114 gray. Seeks are now colorized with a new color of their own.
1116 * Added -zippyMaxGames feature.
1118 * -zippyNoplayCrafty command line option was missing in xboard; fixed.
1119 Thanks to John Perry.
1121 * Fixed bug in detecting when Zippy loses his bughouse partner.
1122 Thanks to Ben Dean-Kawamura.
1124 * allobs fix in 4.0.3 didn't work; corrected it.
1126 * WinBoard will now update the board immediately if a move is made
1127 while the window is being moved or resized.
1129 4.0.3 -- Sun Aug 15 18:44:39 PDT 1999 Tim Mann
1131 * Bugfix: moved winboard wizard functions that send a command directly
1132 to the chess engine from Ctrl+Alt+1 and Ctrl+Alt+2 to Alt+1 and Alt+2.
1133 Ctrl+Alt is equivalent to the European AltGr key, so the old assignments
1134 conflicted with typing an @-sign on some keyboards.
1136 * Bugfix: prevent "If this message stays up, your chess program does
1137 not support analysis" from appearing if AnalysisMode is selected when
1138 already in Analysis or AnalyzeFile mode. Also, deleting analysis window
1139 in WinBoard now switches you to EditGame mode, to avoid the anomaly of
1140 being in an analysis mode with no analysis window present.
1142 * Change all Zippy environment variables to work as command line
1143 options. For now they still work as environment variables too, but
1144 the environment variables are deprecated.
1146 * Use unsigned long to hold node counts from engines.
1148 * Print error instead of crashing on attempts to use xpm or xim pieces
1149 in monochrome mode. Thanks to Jim Torrance for the bug report.
1151 * Tightened pattern recognition for ICS messages sent to Zippy; should
1152 no longer match ICC allobs output. Fixed recognition of when Zippy is
1153 sent a message; small change to FICS output had broken it.
1155 * Zippy now exits if the engine dies unexpectedly.
1157 * Added Zippy "spoofedby" feature; see zippy.README.
1159 * Narrowed the margins on some older WinBoard dialogs to make their
1160 style uniform with the newer ones.
1162 * Bugfix: Changing Ponder Next Move from the Options menu did not take
1163 effect until the next game. This bug was in WinBoard only. Thanks to
1164 Stefan Zipproth for the bug report.
1166 * Got rid of "Internal error: bad move type" message when the engine
1167 makes a move that we can parse but think is illegal. Now the move is
1168 just passed on (which also may be the wrong thing to do).
1170 4.0.2 -- Thu Feb 25 19:55:32 PST 1999 Tim Mann
1172 * Added one more built-in sound choice to WinBoard: move.wav from Pete
1175 * Added new larger piece sizes: big, huge, giant, colossal, titanic.
1177 * Modified the xboard font searcher to be able to use scalable fonts.
1178 The new -fontSizeTolerance flag controls how closely a nonscalable
1179 font must match to be used in preference to a scalable font.
1181 * Zippy environment variables ZIPPYABORT and ZIPPYADJOURN now control
1182 whether Zippy will accept abort and adjourn requests.
1184 * We now determine the variant type being played on ICS, send it as a
1185 command "variant VARTYPE" to the chess engine (if in Zippy mode), and
1186 put it in the PGN tags. See engine-intf.txt for variant names. See
1187 ZIPPYVARIANTS in zippy.README to control what variants Zippy will
1188 accept. Note that this now applies to bughouse, too.
1190 * Zippy now won't do -zippyTalk in a channel unless his handle is
1193 * Zippy now ignores bughouse holdings if not actually playing, instead
1194 of stupidly trying to abort the game. Let me know if other strange
1195 things happen when Zippy is observing a game.
1197 * Set ICS Interaction title bar to "user@server". User name is
1198 determined by parsing message during the login sequence. Zippy now
1199 uses this method to get its name too, so ZIPPYNAME is eliminated.
1200 Problem: with xboard, the title bar gets set to "xterm" upon exit,
1201 since we didn't know what it was to start with.
1203 * Fixed xboard-only bug in -colorChannel1 command line option. Thanks
1204 to Fredrik Sandstrom for the bug report and fix.
1206 * Check for overflow of MAX_MOVES. Still not sure this is checked for
1207 everywhere it needs to be.
1209 * Added .epd to suffixes recognized by WinBoard as position files.
1210 This is a bit of a kludge, as the .fen reading code was not written
1211 with .epd files in mind, but reading them with it is said to work.
1213 * Added ZIPPYGAMESTART feature, suggested by Jason Hoblit. See
1216 * Restored the feature of soaking up the moves from a user-typed "moves",
1217 "oldmoves", or "smoves" ICS command when xboard/WinBoard is idle, but
1218 changed it so that the move list is also echoed to the screen. Some folks
1219 still liked the old feature since it is faster than examine mode, and
1220 printing the moves to the screen should eliminate the confusion it caused
1223 * Bugfix: in WinBoard, starting a click-click move and then clicking on
1224 a black line would cause the source square to be forgotten without taking
1225 the highlight down. Now the errant click is ignored.
1227 * Corrected shortcut key labels for LoadNext/PrevPosition in WinBoard's
1228 File menu. Thanks to Andreas Stabel for the bug report.
1230 * Bugfix: if you had a completely full ICS context menu in WinBoard
1231 (90 items), the last one would do nothing if selected.
1233 * The "computer" engine command added in 4.0.1 was not working; I had
1234 left out part of the code patch. Oops.
1236 4.0.1 -- Fri Feb 12 21:24:15 PST 1999 Tim Mann
1238 This is a minor bugfix release. The first item listed below is the
1239 only interesting new feature.
1241 * You can now type in moves from the keyboard in WinBoard. Either
1242 select TypeInMove from Step menu, or (if you are not in ICS mode),
1243 just start typing. In ICS mode you can type moves into the ICS
1244 interaction window anyway, so I've retained the feature that typing
1245 switches you there. Not implemented in xboard.
1247 * Removed the "noise 1000" command that used to be sent to the chess
1248 engine when entering analysis modes.
1250 * Deleted the feature where we soak up the output of a user-typed ICS
1251 "moves" or "oldmoves" command. This ancient feature is not really
1252 useful anymore, now that "examine" exists, and it caused a lot of
1255 * Increased maximum size of ICS text menu to 90 entries and added
1258 * The command sent to ICS by Zippy at the end of each game can now be
1259 customized with the ZIPPYGAMEEND environment variable.
1261 * We treat xboard.info as a pseudo-source since most people don't have
1262 the tools to rebuild it. But "make install" erroneously had a
1263 dependency on it, even though "make all" did not. Fixed.
1265 * Miscellaneous minor updates and clarifications to engine-intf.txt.
1266 In particular, documented the st and sd commands (support for command
1267 line options -searchTime and -searchDepth), warts and all.
1269 * Added a small code patch from Bob Hyatt to detect when Zippy's ICS
1270 opponent is a computer and send the command "computer" to the engine.
1271 Added this command to engine-intf.txt. Thanks, Bob.
1273 * Bugfix: configure was looking for usleep(), but config.h.in didn't
1274 have an entry for it, so HAVE_USLEEP was never defined. Also, in the
1275 non-HAVE_USLEEP case, there was a possible race condition between the
1276 signal handler and the pause() call. Thanks to Ben Dean-Kawamura for
1279 * Bugfix: a "1..." preceding Black's first move (usually present if
1280 there is a comment on White's first move) would cause the parser
1281 to think a new game started there and report "End of game" on the
1282 current game. Thanks to Dell Garner for the bug report.
1284 * Changed the abbreviation for -searchDepth from -sd to -depth to fix
1285 a clash with -secondDirectory.
1287 * Changed -searchDepth to be orthogonal to the various timing options.
1288 Previously it would search for an unlimited time to the given depth;
1289 now the engine is allowed to choose its search time in the normal way,
1290 but is told to cut off the search early if it reaches the given depth.
1292 * Bugfix: SaveSettings in WinBoard was saving both the long form
1293 option highlightSquareColor and its abbreviation (hsc).
1295 * Fixed a redisplay bug in DisplayBothClocks that could cause White's
1296 clock to be highlighted in EditPosition mode when Black's should have been.
1298 * Fixed Zippy's feature of passing on draw offers from the ICS opponent.
1299 The colorization code was eating the offer before Zippy saw it, so I disabled
1300 colorization of offers while in -zp or -zt mode. (Other types of
1301 colorization are already disabled in Zippy mode for similar reasons.)
1303 * Added some more commands to the default ICS context menu in WinBoard,
1304 and put "(name)" on the ones that insert a playername (or game number).
1306 * Added missing documentation to WinBoard help file: PonderNextMove, the
1307 -ponder/-xponder argument, and the up/down arrow history feature in the
1308 ICS Interaction window.
1310 * Fixed ZIPPYNOPLAYCRAFTY feature to fire only if the opponent is Crafty,
1311 not if some other Crafty is observing the game and kibitzes.
1313 * Fixed bugs in generating "partner" commands when Zippy is playing
1316 4.0.0 -- Sat Jun 20 16:59:47 PDT 1998 Tim Mann
1318 * Fixed WinBoard resizing so that the edges you do not drag remain in
1319 place, even when the final size is different from what you dragged to.
1320 (This doesn't work on NT 3.51 or earlier, if anyone cares.)
1322 * Fixed problems with resizing WinBoard on Windows NT: you no longer get
1323 whitespace around the board, a clipped board, or a lot of flashing during
1326 * Added customization for highlight-square color.
1328 * Bugfix: backend.c wrote to stderr in a few obscure places, which doesn't
1331 * Added Index Number field back to LoadGame/LoadPosition dialog boxes in
1332 WinBoard. This required some extra code to work with both the
1333 Explorer-style dialog boxes and the old-style NT 3.51 dialog boxes. Ugh.
1335 * WinBoard startup dialog now understands -zp mode. The first chess
1336 engine selector is enabled and the value is used.
1338 * Bugfix: ResetGame would send "exit" to engine twice if it was in an
1341 * Bugfix: The response "Illegal move: bk" to the "bk" command, indicating
1342 that it is not implemented, would confuse xboard.
1344 * Bugfix: Ignore empty hints ("Hint:\n") instead of printing a message
1345 saying that some bogus string (often "Hint:") is illegal.
1347 * Bugfix: LoadNextGame/LoadPreviousGame/ReloadSameGame were broken.
1349 3.6.12 -- Sat Jun 13 14:57:10 PDT 1998 Tim Mann
1351 Beta test release of xboard and WinBoard.
1353 * Spruced up xboard man page a bit.
1355 * Added Highlight Last Move to xboard too.
1357 * The revamped xboard mouse click code had several more bugs than the
1358 previous version, so I revamped it again. All fixed now, I hope.
1360 * xboard bugfix: crash in CreatePieceMenu.
1362 * Oops. winboard-3_6_11beta.exe installed 3.6.10beta, not the new version.
1364 3.6.11 -- Fri Jun 12 20:00:48 PDT 1998 Tim Mann
1366 Beta test release of xboard and WinBoard.
1368 * Major reorganization to engine-intf.txt. Some new features added,
1369 many existing features clarified and hints for engine programmers added.
1370 Support for new features added to program.
1372 * Changed defaults for -scp (etc.) back to being independent of -fcp, as
1373 in 3.6.2. That is, the default is no longer to copy the value from -fcp if
1374 -scp is not specified. This will sometimes make command lines longer but
1375 will remove some confusing situations.
1377 * Split -reuseChessPrograms into two options: -reuseFirst and
1378 -reuseSecond. Fixed obscure bugs when reuse is off.
1380 * Detect ICC and change some command usage slightly there: only ICC has
1381 set-quietly; only FICS has iset and bsetup clear. With this feature, we
1382 can now safely use bsetup clear when appropriate instead of deleting each
1385 * Added indent to lines that are wrapped by WinBoard ICS Interaction
1386 window. This seems to tickle a Microsoft bug in the RichEdit control:
1387 occasionally the start of the next line after the wrapped line is indented
1388 too. I think the wrapped indent feature is useful enough that it's worth
1389 having in spite of the bug.
1391 * WinBoard bugfix: bounding box for the board was computed incorrectly by
1392 mouse code. It would think you moved off the bottom of the board before
1393 you really did, so it was hard to drag pieces along the bottom rank on
1394 smaller board sizes.
1396 * Fixed obscure parser.l bug: ambiguity between capture using : instead of
1397 x and email header line. Also removed or simplified a lot of complex
1398 patterns for English (as opposed to PGN) end-of-game indications while I
1401 * Added PonderNextMove option.
1403 * xboard EditPosition piece menus now let you set the side to play by
1404 selecting the "White" or "Black" label at the top of the menu, like
1405 WinBoard. (Both xboard and WinBoard still let you set the side to play by
1406 clicking on the clock.)
1408 * Merged documentation of Crafty and GNU Chess thinking output in
1409 engine-intf.txt. Corrected code in backend.c to match documentation; it
1410 used to require the PV to start in column 27 (!).
1412 * Fixed bug that caused crashes in "-reuseChessProgram false" mode.
1414 * Draw by agreement in Two Machines mode now works as it is supposed to.
1415 Other minor bugs in handling game end messages from machines are also
1416 fixed, and engine-intf.txt is revised in this area.
1418 * Revamped xboard code for handling mouse clicks on the board. In
1419 particular, it had a bug if a click-click promotion move was made.
1421 * Fixed and reinstated optimization for << in analysis modes: send
1422 initString and re-send the board if needed. Sending repeated undos
1423 is bad because Crafty prints some analysis after every one.
1425 * Don't go into a spin loop while pausing between xboard animation frames.
1426 This caused problems, especially when compiling with -O2 on HP-UX.
1428 * WinBoard Options/Colors/RevertToDefaults now also turns off Monochrome
1429 if it was on, and similarly for Options/ICSInteractionColors/RevertToDefaults.
1430 This seemed to confuse people before.
1432 * Bugfix: ICS Interaction context menu items with neither of the two
1433 optional flags set did not work.
1435 * Bugfix: PGN move numbers are optional, but we were insisting on "1"
1436 right after the tags.
1438 * Bugfix: only the first game of an -mg match was loading -lpf or -lgf.
1440 * Other minor fixes and code cleanup.
1442 3.6.10 -- Mon Jun 1 01:32:31 PDT 1998 Tim Mann
1444 * Added ZIPPYNOPLAYCRAFTY feature; see zippy.README.
1446 * Added timestamps for chess engine interaction to -debug output.
1448 * Now allow 10 seconds (was 5) between games in match mode for engines to
1449 respond to "force" command that ended previous game.
1451 * When a game is picked from the game list and the names of White and
1452 Black are known, display them in the window banner instead of the filename
1455 * Changed default for -scp and -sd to be the values of -fcp and -fd.
1457 * Added boxes for both engines to WinBoard startup dialog. Changed to
1458 dropdown boxes whose content can be set from winboard.ini, similar to
1459 the box for ICS name.
1461 * Accept "offer draw" (or "*offer*draw*") from engine to offer a draw.
1463 * Accept "move mmmm" from engine as well as silly "1. ... mmmm" syntax.
1465 * Added support for bughouse engines (Zippy mode only).
1467 * Move bombproofing for engines sending illegal or out of turn moves.
1469 * Always send "xboard\n" to engine as first command. Eliminates need
1470 to run crafty as "crafty xboard".
1472 * Rewrote xboard code for input from engines to fix longstanding bugs.
1473 Previously an engine that sent one line in two separate writes with
1474 some time lapse in between (or perhaps that sent several lines in one
1475 write) could make xboard hang. WinBoard did not have this bug.
1477 * Fixed minor bugs in dealing with illegal moves.
1479 * Added "iset startpos 1" for FICS.
1481 * Removed special support to put "GNU Chess" or "Crafty" in the window
1482 banner instead of the engine's base filename. This gives a more level
1483 playing field for other engines. Also fixed bugs in the code that finds the
1484 engine's base filename.
1486 * Bugfix: Abort or Resign at the very start of a game in chess engine mode
1487 would fail to send "force" to the engine.
1489 * Fixed some minor bugs in new "result" messages, and changed format to
1490 include a trailing PGN comment giving the reason the game ended.
1492 * Changed syntax of /font options in WinBoard; old syntax was assuming
1493 that a font name can't contain a digit, which is wrong. Old font names in
1494 WinBoard.ini files are still accepted.
1496 * Serious further work on getting WinBoard to read/write files in the
1497 "right" directories and documenting exactly what it does.
1499 * Added LoadPreviousPosition, LoadNextPosition, ReloadSamePosition.
1501 * Misc. tiny fixes and cleanup.
1503 3.6.9 -- Sun May 24 20:53:08 PDT 1998 Tim Mann
1505 xboard and WinBoard beta release.
1507 * Tightened up illegal move handling. Illegal or meaningless moves from a
1508 file or chess engine should no longer get translated into a1a1 and blindly
1509 applied. Explicit moves to the same square (like a1a1) no longer make the
1510 piece on that square capture itself and vanish.
1512 * Added AlwaysOnTop feature to winboard.
1514 * Fixed bug in winboard "@" command line indirection operator.
1516 * Removed buggy "optimization" code for ToStart in analysis modes.
1518 * Fixed typo bug in zippy.c that would often cause winboard to crash
1519 right after starting a game in -zp mode.
1521 3.6.8 -- Sat May 23 22:23:19 PDT 1998 Tim Mann
1523 xboard and WinBoard beta release.
1525 * Added -firstDirectory and -secondDirectory so that chess engines can
1526 be started in a different directory from xboard/WinBoard itself.
1528 * Added -matchGames to allow more than one game in -matchMode. The games
1529 are played with colors alternating between the two chess engines. Had to
1530 add a time delay at the end of each game to catch up with game ending
1531 messages from both chess engines -- yuck.
1533 * Changed TwoMachines mode to have firstChessProgram play White by
1534 default. Added -firstPlaysBlack to restore old behavior.
1536 * Major rework of code in backend.c for dealing with first and second
1537 chess engines. Generalized the code and created a struct type with one
1538 instance for each engine. Several small bugs fixed along the way.
1540 * Fixed bugs in Abort in local chess engine mode.
1542 * Tightened pattern matching to recognize moves from machine. Should cure
1543 bogus "Illegal move" errors while Crafty is pondering with Show Thinking
1544 on, among other things.
1546 * WinBoard keeps focus in board window after popping up a comment due to
1547 Forward/Backward/ToStart/ToEnd commands.
1549 * Finally got rid of warnings on compiling moves.c under Windows.
1551 * Fixed so WinBoard will compile on machines where WM_MOUSELEAVE is not
1554 * Removed various bits of unused code.
1556 * Parse (and ignore) NAGs in PGN files.
1558 * Updated engine-intf.txt.
1560 * Send "result R" to the chess program at the end of each game, where
1561 R is the PGN result 1-0, 0-1, 1/2-1/2, or *.
1563 * Bugfix: suppress animation when loading a game with timeDelay=0.
1565 * Bug fix: pondering output from Crafty that contained "..." could be
1566 mistaken for a move, causing bogus error messages and general chaos.
1568 * xboard "make clean" bug fix: moved things created by configure to be
1569 removed only by "make distclean".
1571 * Fixed a remaining case where move was being animated before being
1572 relayed to opponent.
1574 * Backend was reversing time/otim commands to the chess program (new bug),
1575 and was often not sending them on the first move of a game or the first
1576 move after a mode change (old bug). Fixing the latter required a kludge
1577 to work with both GNU Chess and Crafty, because Crafty swaps white and
1578 black clock times when it swaps sides, while GNU Chess does not. The
1579 kludge is that we always make sure the chess engine thinks its opponent is
1580 on move before we set the clock. This will sometimes result in sequences
1581 like "white\ntime xxx\notim yyy\nblack\ngo", or the same with white and
1584 * Removed last trace of old -whiteString and -blackString arguments.
1586 * Fixed so that you can type "bd" into the Direct Command dialog when
1587 debugging gnuchess, without having xboard parse the clock display
1588 (starting with "White") as "White wins" and end the game.
1590 * Changed moves.c to make a distinction between IllegalMove (where we
1591 could tell what move was intended, but it violates the chess rules) and
1592 MeaninglessMove (where we could not tell). This is a step towards getting
1593 rid of cases where we translate meaningless moves into "a1a1", but some
1594 work is probably needed to track them all down.
1596 * Fixed bug in WinBoard monoMode dragging.
1598 * Changed WinBoard to new style file dialogs. In the process, disabled
1599 the feature that let you enter the index number of a game or position within
1600 the file in the dialog. This is no loss in LoadGame, as you can pick your
1601 game from the game list dialog that follows, but it does remove some
1602 functionality from LoadPosition.
1604 3.6.7 -- Mon May 18 21:25:00 PDT 1998 Tim Mann
1606 xboard and WinBoard beta test release. I've been unable to reproduce some
1607 reported drawing bugs, so they may still not be fixed.
1609 * Changed PopUpErrors option to PopupMoveErrors, which is more useful, and
1610 changed default to off. Errors other than move errors should always be in
1611 popups; they are often too big for the message area and too important to
1612 put where they can be easily missed. But it seems good to get rid of the
1613 popups for move errors by default.
1615 * xboard analysis window no longer forces itself to top whenever there is
1616 new output. Also, now uses built-in Xaw word wrapping instead of trying
1617 to do its own; works better.
1619 * Bugfix: Reset did not take Crafty out of analyze mode.
1621 * A chess engine no longer has to claim to be Crafty to be able to use
1622 AnalysisMode and AnalyzeFile; it just has to implement the analyze
1623 command as Crafty does. Put in heuristics to generate more informative
1624 error messages if the engine does not support analyze, and checked that
1625 they work at least with GNU Chess.
1627 * Added click-click moving, HighlightLastMove, and HighlightDragging to
1628 WinBoard. The highlight features are unlikely to go into xboard unless
1629 the xboard drawing code is cleaned up to do *all* drawing on the board
1630 from DrawPosition, as WinBoard does. This is low priority for me.
1632 * Eliminated bogus "Error gathering move list: no header" popup. You
1633 could get this by observing two fast games at once without turning off
1636 * Disable WinBoard Sounds menu entirely in -ncp mode, since not even
1637 MoveSound is used in that mode.
1639 * WinBoard bugfix: Several problems were caused if the user changed
1640 WinBoard's current directory in a Load, Save, or Browse dialog. In
1641 particular, WinBoard.ini would get saved in the wrong directory, and
1642 sound .wav file names would not get saved with a full pathname. I think
1643 all such problems are now fixed.
1645 * WinBoard bugfix: iconizing the board after an aborted mouse resize would
1646 (partially) resize it to Tiny.
1648 * WinBoard bugfix: board was not being drawn in color on 256-color
1649 displays. This bug was introduced in 3.6.6.
1651 3.6.6 -- Tue May 12 17:43:43 PDT 1998 Tim Mann
1653 xboard and WinBoard beta release. Note: not all reported bugs are fixed.
1655 * Move animation in WinBoard, programmed by Henrik Gram. Great stuff!
1657 * Animate backward moves too.
1659 * xboard bugfix: -font (and friends) can now specify a font alias (such
1660 as "fixed"), not just a full X Consortium name pattern. Previously this
1661 would give a resource conversion error message.
1663 * Some coding style cleanup in xboard.c.
1665 * Earlier error check for moving wrong color piece in EditGame mode.
1667 * Completed fix to pattern matching; see 3.6.5.
1669 * Fixed some software rot bugs in Zippy.
1671 * Split AnimateDragging as separate option from AnimateMoves.
1673 * Added FlashMoves to options menu and -flash/-xflash to command line
1674 options (xboard only).
1676 * Some preliminary work on visible bughouse holding support. Most of the
1677 code is not present in this release because I have not gotten it working
1678 properly yet; my first approach went down a blind alley and I had to
1679 remove most of the partially working code in preparation for a rewrite.
1681 3.6.5 -- Fri May 8 14:22:09 PDT 1998 Tim Mann
1683 Not generally released.
1685 * Pack bughouse holdings display in banner more tightly when board is one
1686 of the smaller sizes (when smallLayout or tinyLayout is true, that is).
1687 An interim measure, but should help.
1689 * Completed fix to make move list parsing recognize the end condition and
1692 * Fixed pattern matching for chatter (tells, etc.) to be more reliable.
1693 This should reduce the incidence of colors starting in the wrong place and
1694 of incorrectly matching things that look like other patterns inside
1695 chatter, such as "shout <12>". (These errors were already rare.)
1697 * WinBoard now lets you customize the list of ICS's in the startup dialog.
1698 For now, at least, requires editing WinBoard.ini with a text editor.
1700 * Bug fix: WinBoard window sizing and position setting save/restore did
1701 not work right when the taskbar was at the top (or left side) of the
1702 screen and not in autohide mode.
1704 * Merged xboard click/click mode and drag mode, and deleted
1705 ClickClickMoving option on menu. Now if you click on a piece, it
1706 highlights and a further click on another square will move it. (A second
1707 click on the same square takes down the highlight.) Or if you press down
1708 on a piece and start to drag, you can drag it to a new square.
1710 * When making click/click style moves, if your second click is on a piece
1711 of the same color, instead of saying "Illegal move", we now cancel the first
1712 starting square, replace it with the second, and wait for another click to
1715 * Separate -secondInitString. Default: same as -initString. Suggested by
1718 * Patch from Frank McIngvale to make animation work with XIMs. Yay!
1720 * Changed move animation to happen after move is passed on to ICS or the
1721 chess engine, where applicable. Fixed problems with updating moveList
1722 that this uncovered.
1724 * Changed game list to show PGN result token for each game.
1726 * The usual minor bug fixes.
1728 3.6.4 -- Thu Apr 30 23:14:43 PDT 1998 Tim Mann
1730 xboard and WinBoard beta test release.
1732 * xboard documentation updated, both man page and info file. An attempt
1733 to generate both from the same source with LinuxDocSGML was abandoned, at
1734 least for now. WinBoard doc updated too.
1736 * Merged updates to animation code from Hugh. Fixed a couple of remaining
1737 bugs, mostly to do with handling Pause mode correctly.
1739 * Added SaveSettingsOnExit to WinBoard.
1741 * WinBoard now saves the last screen position of the Comment, Edit Tags,
1742 Game List, and Analysis windows (in addition to the board and ICS
1743 Interaction windows) in WinBoard.ini.
1745 * WinBoard now provides a way to customize the right-button context menu
1746 in the output area of the ICS Interaction window. For now, requires
1747 editing WinBoard.ini with a text editor.
1749 * Various minor fixes to ICS message recognition, most affecting only Zippy.
1751 * Colorize the notification when someone sends you a message while you are
1752 logged in, not the output of the "messages" command.
1754 * Fixed colorization to turn off at the right place more reliably.
1756 * Added a new color and WinBoard sound for "requests": abort, adjourn,
1757 draw, pause, and takeback. The same color and sound are used for all of
1760 * Added GUI to change sounds in WinBoard.
1762 * Suppressed WinBoard error popup when a sound can't be played. They were
1763 popping up when two separate WinBoards tried to play a sound at the same
1764 time (such as during a bughouse match).
1766 * Fixed WinBoard crash when a sound file didn't exist.
1768 * WinBoard ports of timestamp and timeseal now produce decent error
1769 messages if they fail to connect, and WinBoard captures the messages and
1770 puts them into a popup. Previously WinBoard would exit with no message on
1773 * WinBoard resizing with mouse improved; now accurately picks the largest
1774 size that fits in the new area.
1776 * Added option to turn off error message popups.
1778 * Added sizes slim, dinky, and teeny.
1780 * Fixed some minor problems with error message wording.
1782 3.6.3 -- Mon Feb 23 19:08:57 PST 1998 Tim Mann
1784 xboard beta test release only. Man page is updated for the changes, but info
1787 * Bug fix: LoadGame could not load a PGN game whose first move was
1788 castling (which is possible from setup positions).
1790 * Bug fix: we were ignoring illegal move messages from chess engines in
1791 modes where the engine is refereeing but not participating (EditGame,
1792 LoadGame, AnalyzeFile). The problem was in a workaround for a Crafty bug,
1793 where Crafty generates a bogus illegal move message if a "." (used by
1794 the PeriodicUpdates feature) is sent in analysis mode when the current
1795 analysis reveals a forced mate. Installed a different workaround (that
1796 works in most but not all cases) and reported the Crafty bug. Bob Hyatt
1797 replied with a fix, so the Crafty bug should be gone in Crafty 14.12 or so.
1799 * WinBoard only: enabled resizing board with the mouse. It snaps to the
1800 nearest (but not too much larger) predefined size.
1802 * The xboard default font is now sized according to piece size, just as
1803 clockFont and coordFont have always been.
1805 * Added more sizes: bulky, moderate, average, middling, mediocre, petite.
1807 * xboard only: Added Animate Moves and Click-Click Moving to Options menu.
1809 * xboard only: Added code to animate piece movement, from Hugh Fisher.
1811 * New feature: autoflag is implemented in MachineWhite, MachineBlack, and
1812 TwoMachines modes. If it is on and either a chess program or the user
1813 oversteps his time, xboard will automatically call the flag and end the
1814 game. This feature was requested by someone who runs matches between
1815 programs and wants to penalize GNU Chess for its habit of running slightly
1816 over at the end of a time control. I personally think it's pointless.
1818 * Fixed a bug in Zippy's pattern matching; he can now reply to ICC
1821 * Generate prettier notation for illegal moves. If a move is illegal only
1822 because it leaves the player in check, generate notation as if that were
1823 not illegal. For instance, if two knights are a knight's move away from
1824 f3, one on g1 and one on e5 that is pinned, the notation would be Nf3 to
1825 move the g1 knight, Nef3 to move the e5 knight. (Suggested by Philippe
1826 Schnoebelen.) In addition, if a move is illegal because the type of piece
1827 moved cannot go that way, would be jumping over another piece, etc., we
1828 give fully disambiguated coordinate notation; for example, Ng1g3, Ke1xe8,
1829 d2xd8=Q, etc. An alternative would be to still write Ng3 if there is only
1830 one knight on the board, or Ngg3 if the other knight is not on the g file,
1831 but life is too short to code up all this stuff, and perhaps the way I did
1832 it is better as it emphasizes that this move was really made despite being
1833 illegal. I wonder if the new PGN standard revision will speak to notation
1836 * Fixed gross bug from 3.6.2: if a chess program said "checkmate" and
1837 White was left on move, the PGN outcome was "1-0 {Black mates}" instead
1838 of "0-1 {Black mates}"! The bug occurred only for that specific string.
1840 3.6.2 -- Wed Jul 23 16:47:29 PDT 1997 Tim Mann
1842 * There was a bug in backing up from the end of a game against a chess
1843 engine, introduced when -reuse mode was added. Fixed.
1845 * Recognize "{" as terminating an ICS move list. Previously we needed to
1846 see a prompt (containing %), but occasionally ICC can send more stuff
1847 right after a move list with no prompt in between.
1849 * In WinBoard, -mm now implies -cp, so you don't get the startup dialog.
1851 * WinBoard startup dialog no longer sets -scp. People used to get
1852 confused because they would give the -fcp and -scp arguments, but omit
1853 -cp. This would bring up the startup dialog, which would set both -fcp
1854 and -scp to the value in the engine name box. Now you can change -scp
1855 only with the command-line argument. That will confuse some people too,
1856 but hopefully fewer. I think overall it's better than putting spaces for
1857 both -fcp and -scp in the dialog, which would puzzle newbies.
1859 * Bug fix: Analyze File mode now works in WinBoard.
1861 * Bug fix: WinBoard window no longer cuts off part of the bottom row if
1862 the menu bar wraps to a second line.
1864 * Accept game end messages of the form "PGN-result {comment}" from the
1865 chess engine, where PGN-result is 0-1, 1-0, or 1/2-1/2. Accept "resign"
1866 or "computer resigns" from the chess engine as a synonym for "0-1 {White
1867 resigns}" or "1-0 {Black resigns}". Accept any message from the chess
1868 engine containing "game is a draw" as a synonym for "1/2-1/2 {Draw}".
1869 Accept "White resigns" or "Black resigns".
1871 * Enable "Action / Draw" menu item in chess engine mode. It sends the
1872 command "draw" to the engine. Accept any message from the chess engine
1873 containing "offers a draw" as a draw offer. WARNING: Draw offers from the
1874 user and the engine (or from two engines) are not yet matched up by xboard
1875 in chess engine mode. Two engines could get into a loop offering each
1878 * Bug fix: Game end messages from the chess engine are always ignored in
1879 Zippy mode. Previously they could sometimes be processed, which was
1880 sometimes making Zippy hang at the start of a new game that followed
1881 quickly after an old one.
1883 * Zippy can now respond to titled players in channels. Zippy will avoid
1884 talking to himself in a channel if he knows his own name.
1886 * Bug fix: in colorization arguments, the bold setting was being ignored
1887 if the background color was defaulted. (xboard only.)
1889 * Extended ParseFEN to accept Crafty 12.2's interpretation of FEN.
1890 If fewer than 8 squares are given in a row, or fewer than 8 rows are
1891 given, the uncovered squares are empty. Also, there can be a / after the
1894 3.6.1 -- Sat May 17 01:02:33 PDT 1997 Tim Mann
1896 * Bug fix: Hitting escape while entering a password on WinBoard no longer
1897 sets the font color back to black (which made further typing visible).
1899 * Bug fix: On Windows NT 4.0, WinBoard /ics /icshelper=timestamp would
1900 often hang if you tried to exit with the Exit menu item, the [X] button,
1901 etc. The same fix may also have corrected the problem where running a
1902 chess program with /xreuse would sometimes crash Windows 95 (but not NT)
1903 when the chess program was killed and quickly restarted.
1905 * Bug fix: Periodic Updates would not work if turned on after having been
1906 off. Also, the default was needlessly "off" in WinBoard.
1908 * Zippy bug fix: Continuing an adjourned game was totally broken. The
1909 wrong moves, or no moves at all, were being fed to the chess program.
1911 * WinBoard change: Giving -ics without -icshost now pops up the startup
1912 dialog with "Use an Internet Chess Server" pre-selected, so that you get a
1913 menu of chess servers instead of going directly to ICC.
1915 * Bug fix: WinBoard's SaveSettings was saving -icshost, -icsport, and
1916 -icshelper in winboard.ini. This causes a problem if you use a different
1917 icshost later that needs the default values for icsport (5000) and
1918 icshelper ("", meaning none).
1920 * Disabled complaints about unexpected "[Ii]llegal move" messages from
1921 the chess program; we still get them at times.
1923 * Greatly simplified the code for Move Now and SIGINT (ATTENTION). Fixes
1924 the bug where Move Now did not work with GNU Chess in WinBoard, and
1925 several more obscure bugs as well. Reintroduces a minor bug: GNU Chess might
1926 not think on your time after a Move Now command. Trying to fix this
1927 causes too many other problems. Documented change in engine-intf.txt.
1929 * Cleaned up code for obtaining ratings from ICS. It was kludgey and may
1930 have had bugs on systems with no "Creating:" message. It should fail
1931 gracefully there, just not finding the ratings.
1933 3.6.0 -- Thu May 8 19:55:58 PDT 1997 Tim Mann
1935 * WinBoard now has right-button context menus in the ICS Interaction
1936 window. Some of the items do immediate commands on the player name you
1937 have selected or pointed to. (Suggested by Paolo Casaschi.) Also, the
1938 middle button or shift+right does a immediate Copy and Paste.
1940 * Fixed a bug in Zippy's wild rejection. The bug was causing Zippy to
1941 reject all forms of wild. Now it rejects only 1, 9, 16, 17, and 24, as
1942 was intended. These variants have different rules, while the other
1943 variants defined so far only have different starting positions.
1944 (Actually, wild 2, 3, and 4 never allow castling, but may sometimes by
1945 chance have king and rook start on squares where castling appears legal.
1946 This could cause a problem later.)
1948 * Zippy now resumes adjourned games by feeding the chess program
1949 the move list instead of the position. Setting -getMoveList to False
1950 restores the old behavior. Feeding in the move list is better because
1951 it enables the chess program to correctly handle en passant legality,
1952 castling legality, draw by repetition, and draw by the 50 move rule.
1954 * Added a WinBoard startup dialog for people who run WinBoard.exe without
1955 using the Start menu or reading the help file. Instead of being dumped
1956 directly into GNU Chess mode, you now get a menu of choices. You now have
1957 to give the new WinBoard -cp option to go directly into chess engine mode.
1958 I did not add this feature to xboard.
1960 * Handling of "illegal move" from Crafty is now back on. (It was turned
1961 off in 3.4.6; see below.) Crafty 12.0 doesn't seem to send bogus ones
1962 anymore. I did have to suppress sending time and otim in analyze mode to
1963 make this work, but there is no harm in that.
1965 * Zippy now sends "gameend" to ICS at the end of each game. You can alias
1966 this to "seek" or whatever you like.
1968 * Added Crafty support for Move Now, using the "?" command. We test
1969 whether this command exists by trying it once at the start of the first
1970 game, before it really makes sense. If we don't get a message like
1971 "Illegal move ... ?", we assume it's OK. (We're careful about this
1972 because sending a "?" to GNU Chess on Move Now keeps it from pondering the
1973 next move as it should.)
1975 * Added support for a tellusererror command from the chess engine. See
1978 * Attempted to make engine-intf.txt complete.
1980 * Minor fixes/cleanup to GameEnds code, to be sure we always interrupt
1981 when needed, and always undo an extra move generated by stopping the chess
1982 program while it is thinking.
1984 3.5.7 -- Sat May 03 22:37:44 PDT 1997 Tim Mann
1986 Beta release of both xboard and WinBoard.
1988 * Updated xboard documentation. I really wish the man page was built from
1989 the info file instead of being separate! It's a pain to update them both.
1991 * Updated documentation of the interface between XBoard/WinBoard and chess
1992 programs, and renamed it to engine-intf.txt.
1994 * Added support for tellics, telluser, and askuser commands from the chess
1995 engine. See engine-intf.txt.
1997 * Various bug fixes. On WinBoard, 256 color displays are finally handled
1998 right; no more color flashing when you switch windows unless the colors
1999 really need to be updated. Also, I think the problem of the console font
2000 failing to change or changing back by itself is finally fixed.
2002 3.5.6 -- Tue Apr 29 03:08:00 PDT 1997
2004 Beta release, WinBoard only. ChangeLog was out of date in release,
2007 * Added ICC timestamp and FICS timeseal to WinBoard distribution. These
2008 are my own ports to Win32, based on and used by permission of the owners
2009 of the proprietary source code (Daniel Sleator for timestamp, Henrik Gram
2010 for timeseal). The owners permit these programs to be distributed only in
2011 binary form (to help prevent cheating), so to avoid running afoul of the
2012 GPL, I have kept them as separate programs, not linked into the WinBoard
2013 address space. Updated Start menu icons to use them.
2015 * Miscellaneous smaller changes.
2017 3.5.5 -- Fri Apr 25 03:06:00 PDT 1997
2019 Beta release, WinBoard only. ChangeLog was out of date in release;
2022 * Added simple sound support to WinBoard.
2024 * Updated WinBoard documentation.
2026 * Internal implementation of the telnet protocol is now more complete.
2027 You can now hop through a VMS host on the way to ICS. For example, do
2028 "xboard -ics -icshost vms.host.edu -icsport 23", then log in. Do not use
2029 the -telnet flag; that says to use an *external* telnet program. To avoid
2030 double echoes, you need to force character mode in VMS telnet after
2031 connecting from VMS to ICS. Do "^]^Mset mode char^M^M".
2033 * Display opponent names in the title bar for MachineWhite, MachineBlack,
2034 and TwoMachines modes.
2036 * WinBoard now has an installer, built with InstallShield. The installer
2037 works with a binary-only distribution. Sources are still freely
2038 available, but now separately.
2040 * Added SaveSettings to WinBoard, which saves current option settings to
2041 winboard.ini. Made sure all options can be saved and loaded, including
2042 fonts and com port settings.
2044 * If the game ends while you are dragging a piece, we now don't let you
2045 finish the move. Formerly the move was accepted and your opponent's clock
2046 would start running again.
2048 3.5.4 -- Fri Apr 18 01:15:24 PDT 1997 Tim Mann
2050 Beta test release of WinBoard and xboard. The documentation remains
2053 * Many fixes and improvements to new WinBoard user interface code.
2055 * In Zippy mode, avoid sending another copy of the same move to the chess
2056 program if ICS sends us another copy of the board image. Hard to believe
2057 it took me until now to diagnose and fix this problem!
2059 3.5.3 -- Sat Apr 12 19:49:33 PDT 1997 Tim Mann
2061 Beta test release of WinBoard and xboard.
2063 * Fixed fatal bug in WinBoard input handling.
2065 * Made code to stop chess program for reuse a bit smarter. Removed kludge
2066 of "white" in initString; it didn't work well, and is unneeded
2067 with Crafty 11.21 and later.
2069 3.5.2 -- Sat Apr 12 15:40:01 PDT 1997 Tim Mann
2071 Beta test release of WinBoard.
2073 * Ignore check and permit promotion to King during suicide games; no need
2074 to turn off TestLegality.
2076 * Renamed CheckLegality to TestLegality to avoid confusion with the chess
2079 * Added Rematch to Action menu.
2081 * WinBoard now has a custom ICS interaction window with scrollback, a
2082 separate line for input, and colorization. Accelerators that conflict
2083 with normal editing keys were changed (by requiring Alt+) so they can work
2084 in both the console and the main window.
2086 * WinBoard error popups are now non-modal and disappear when you make a
2087 new move, as in xboard.
2089 * Configure now defaults to --disable-ptys on all systems. If anyone has
2090 an ancient SysV system where pipes don't work with select, they can still
2091 do "configure --enable-ptys" explicitly. I would appreciate getting a bug
2092 report if this happens to anyone, with complete output from configure and
2095 * "make install" now makes the installation directories too.
2097 * Fixed a bug that would cause an "Illegal move" message for Black from
2098 GNU Chess to be incorrectly considered bogus.
2100 * Handle name changes during an ICS game (FICS bname and wname commands).
2102 * You can force both chess programs to be killed at the end of each game
2103 by turning off the reuseChessPrograms option. There are still some
2104 problems with reusing Crafty even in version 11.20.
2106 * Now the second chess program stays around by default too, if it ever
2109 3.5.1 -- Sat Apr 5 16:47:48 PST 1997 Tim Mann
2113 * Don't kill off and restart the chess program for each game; keep the
2114 same one running, using the "new" command to start a new game. This
2115 change works around the problem in Windows 95 that makes WinBoard crash it
2116 at times, and is generally desirable to make new games start faster. The
2117 second chess program (for TwoMachines) is still killed at the end of the
2118 game, and unfortunately this can still crash Windows 95. Temporarily
2119 added "white" to the initString to make this work with Crafty 11.20, which
2120 has a minor bug in "new". Older versions of Crafty have worse bugs in
2121 "new"; they should not be used with this version of xboard.
2123 * Support for FICS suicide chess: Parse illegal moves (that leave King in
2124 check) in game history. If CheckLegality is off, allow promotion to King
2125 and illegal moves in game files. We still generate e2e4 style notation
2128 * Handle FICS "has timeseal; checking" message.
2130 * Changed the coords from white back to black; this was a bug.
2132 * Fixed problems compiling with K&R compilers.
2134 * Fixed an old bug in RegisterMove that was crashing cmail on some systems
2137 3.5.0 -- Thu Jan 2 16:59:49 PST 1997 Tim Mann
2139 Thanks to Frank McIngvale for much of the work on versions 3.4.4 and above!
2141 * Fix Crafty resumed game time bug (frankm)
2143 * Word wrap text in Analysis window (frankm)
2145 * More debug info for XPM loading (frankm)
2147 * Replaced config.sub, config.guess, etc., with up-to-date versions from
2148 autoconf 2.12. Hopefully this will fix problems on Pentium Pro machines.
2150 * Removed some Makefile gunk that was causing looping for one person.
2152 3.4.7 -- Thu Dec 19 14:22:41 PST 1996 Tim Mann
2154 All changes from Frank:
2156 * Retrieve ratings from ICC (and FICS, etc., when they add the Creating:
2157 message), save them in the PGN tags, and pass them to Crafty in Zippy mode.
2159 * Add settable time delay between characters in ICS login script.
2161 * Colorize messages like personal tells. Fix false recognition of channel
2164 * Pass "tells" from Crafty through to ICS (in Zippy mode).
2166 * Implement ~/ filename convention from C shell for game and position file
2169 * ZIPPYACCEPTONLY feature for testing.
2171 3.4, patchlevel 6 -- Sat Nov 23 16:58:50 PST 1996 Tim Mann
2173 * Put recognition of "illegal move" messages from Crafty for
2174 illegal castling, etc., inside an #if that is currently turned off,
2175 because of a bug in Crafty that generates bogus "illegal move" messages
2176 after some moves that are actually legal and accepted by Crafty.
2178 * Added -checkLegality option; previously this could not be turned off.
2180 * Fixed an old bug in finding default board size parameters.
2182 * Differentiated among channel tell, kibitz/whisper, and personal tell/say.
2184 * Fixed a bug in detecting Xpm in the configure script.
2186 3.4, patchlevel 5 -- Mon Nov 18 16:22:53 PST 1996 Tim Mann
2188 * Added zic2xpm to the kit; it had been omitted by mistake.
2190 * Added some default colors for -colorize
2192 3.4, patchlevel 4 -- Sat Nov 16 18:10:17 PST 1996 Tim Mann
2194 This is meant to be a beta release in preparation for version 3.5.
2196 * Added InfoXBoard and ManXBoard to the Help menu.
2198 * Made Frank's ICS input box optional, defaulting to off.
2200 * Merged in Frank McIngvale's XbKit. Many new features, including
2201 -clickClick mode, the Analysis modes, piece flashing, ZIICS import,
2202 ICS text colorization, and the ICS input box. Many thanks to Frank for
2203 supplying and documenting this code.
2205 3.4, patchlevel 3 -- Mon Nov 11 18:23:14 PST 1996 Tim Mann
2207 Small set of changes made while Frank McIngvale was working on XbKit in
2208 parallel. Unreleased in this form.
2210 * Updated zippy.README.
2212 * Removed useless X event handler and removed strange code for copying
2213 form translation table to board that worked around the bug it caused.
2214 This makes changing bindings in .Xdefaults more straightforward.
2216 * Now pressing the Control key steps back one move, and releasing it steps
2219 * Moved quit from "q" to "Q" for greater safety.
2221 * Use "unobserve" instead of "observe" to stop observing; needed on FICS.
2223 * Support for interface variable.
2225 * Strip titles from people who are talking to us, so (for example) Zippy
2226 won't try things like "tell Darooha(*) hello". Needed on FICS.
2228 3.4, patchlevel 2 -- Tue Jul 9 19:06:42 PDT 1996 Tim Mann
2230 This patchlevel is not planned to be an announced release. It's in
2231 preparation for integrating Frank McIngvale's XbKit. It mostly contains
2232 minor fixes I've accumulated since 3.4.pl1.
2234 * WinBoard /telnet option now fires up an external program, as
2235 with xboard, instead of trying to use a feature of NT 3.1 that does not
2236 exist in later versions of NT or in Windows 95. ChangeLog for 3.4.pl1
2237 said this had been implemented there, but it really wasn't.
2239 * Indicating player to move by the icon color now works under Windows 95.
2241 * WinBoard now kills the chess program when you exit using the system menu
2242 or the [X] button. Thanks to Michael Lowe.
2244 * Minor changes to Zippy, including: Now understands wild challenges on
2245 FICS; these used to crash it. Removed limit on how fast a game will be
2246 accepted. Use "set formula ..." on the chess server to limit this if you
2247 are using GNU Chess. Now sends correct opponent name to Crafty.
2249 * Added some missing default values to documentation. Thanks to Stuart
2252 * Bugfix: Trying to print "No fonts match pattern" error message would
2253 crash. This can happen to Linux users who don't install Helvetica, for
2256 * Bugfix: Defaulting feature in -size n,n,n,n,n,n would put us in an
2259 * Added more directories to search for Athena widgets on HPUX.
2261 * New cmail (3.12) from Evan Welsh; includes small fix from Kayvan Sylvan.
2263 * Recognize "illegal move" messages from Crafty for illegal castling, etc.
2265 * Bugfix: "name" command added to zippy.c for Crafty was producing error
2266 message if GNU Chess was in use.
2268 * In bughouse mode, suppress holding messages from console window; show
2269 holdings only in banner.
2271 * Minor fixes/cleanup to Makefile.in and configure.in.
2273 3.4, patchlevel 1 -- Mon Dec 11 13:43:12 PST 1995 Tim Mann
2275 * This patchlevel updates WinBoard to match xboard, and includes a few
2276 fixes and minor improvements. "-size tiny" and "-size n,n,n,n,n,n"
2277 are still not implemented for WinBoard.
2279 * Installed support for Crafty based on code from Bob Hyatt.
2280 Currently the only documentation for this is in the FAQ, and a few
2281 things don't work with Crafty 8.23. Please do not report these
2282 problems as bugs in either xboard or Crafty. Bob and I know about
2283 them. The worst ones (if not all of them) should be fixed in Crafty
2286 * Changed the kludge command we send when gnuchess wants to print
2287 something that doesn't end with a newline, from "help" to "bogus".
2288 This works because the error message gnuchess prints ends with a
2289 newline. It also improves compatibility with Crafty, which doesn't
2290 need the kludge, but for which sending "help" causes a problem.
2292 * Don't draw grid at all if lineGap is 0; previously we drew the grid
2293 with X "0-width" lines (usually 1 pixel wide) and then overwrote it.
2295 * Makefile: Removed xboard.info from "all" target so we won't try to
2296 rebuild it, because this fails on hosts that don't have makeinfo
2297 installed. Other minor fixes to "clean" targets, etc.
2299 * Fixes and cleanup to Auto Comment code that handles continuation
2300 lines and highlighting.
2302 * Auto Observe now tries to observe the game from the point of view of
2303 the player who was on your gnotify list. Requested by rng.
2304 Limitations: We can't tell which player it was unless you have ICS
2305 highlighting turned on. Also, currently "observe foo" works as
2306 required (observing from foo's point of view) only on ICC, but FICS
2307 will probably implement this soon.
2309 * "-size tiny" now makes the default font smaller automatically. This
2310 was implemented by introducing an extra Form widget in the hierarchy
2311 for all xboard windows, named either normalLayout, smallLayout, or
2312 tinyLayout. So you can have resource specifications that apply only
2313 to certain layouts; in particular, XBoard*tinyLayout*font.
2315 * Bug fix: EditGame or EditPosition while playing or examining still was
2316 not really being permitted.
2318 * WinBoard bug fix: On the EditPosition menu, King did not work.
2320 * Added text catalog of WinSock error messages to WinBoard, because
2321 Microsoft still has not put them in the system message catalog.
2323 * Removed support for older ICS game-ending messages that do not have
2324 a PGN result token (*, 0-1, 1-0, or 1/2-1/2) after the closing '}'.
2325 The code for older messages was sometimes firing on the newer
2326 messages, due to parsing ambiguity. If the current code sees an old
2327 message, it will understand that the game is over, but will always
2328 display * as a result token instead of trying to guess the result by
2329 interpreting the text message.
2331 3.4, patchlevel 0 -- Tue Nov 21 01:02:50 PST 1995 Tim Mann
2333 * This patchlevel was released for xboard only.
2335 * Updated the info file. It should now be as up-to-date as the man page,
2336 with good English except in the parts that pertain only to AmyBoard.
2338 * Added "-size tiny", requested by Bob Hyatt. Also cleaned up bitmap
2339 support and added "-size n,n,n,n,n,n" to allow arbitrary-sized bitmaps,
2340 if the actual bitmaps are supplied by the user.
2342 * Updated bughouse support.
2344 3.3, patchlevel 4 -- Sat Nov 18 02:27:21 PST 1995 Tim Mann
2346 * Unreleased beta that works with preliminary FICS bughouse code. Will
2347 need changes before release to track FICS message changes.
2349 * Removed use of .EX macro from man page. It is not supported by some
2350 nroff -man macro packages, notably the one on Slackware Linux. Switched
2351 to boldface for references to xboard and other commands within the man
2352 page, as this seems to be the modern way.
2354 * Bug fix: If ICS rejected a move, it was correctly undone on the board,
2355 but the message widget still displayed the bad move. Reported by DAV.
2357 * Normally, xboard in ICS mode fetches the move list whenever the board
2358 display switches to a new game. Doing this is now an option
2359 (getMoveList) that can be turned off, which is useful if you are watching
2360 multiple blitz games. Requested by rng.
2362 * Move list fetching code is now smarter: it ignores a move list if it is
2363 not for the right game.
2365 * Added support for bughouse as implemented on FICS. Holdings are shown
2366 in the window title in place of the strength numbers. A menu on mouse
2367 buttons 2 and 3 (same on both) lets you drop pieces. There is no checking
2368 as to whether you actually hold the piece you are trying to drop; we rely
2369 on ICS to check that. Notation of the form P@f7 is generated and parsed.
2370 The mate detector does not understand that non-contact mate is not really
2371 mate in bughouse, but this does no real harm. It results in a "#"
2372 suffix being displayed on the move notation, but xboard does not assume the
2375 * Bug fix: Promotion to a knight was not working with ICC! Thanks to
2376 Wendigo for the report.
2378 * Bug fix: Special pty code for host types *-*-aix3* and *-*-irix3*
2379 (supplied from configure.in) had a bug that would cause childio.c to
2380 fail to compile, due to a "continue" that was not within a loop.
2382 * Bug fix: In pgntags.c, memory was being freed while still in use. One
2383 symptom this caused was that on some machines, cmail would fail with a
2384 message that it could not find the BlackNA tag. The error was in some
2385 submitted code that I included in version 3.2.pl3 without reading
2386 carefully enough. Anders Forberg noticed the symptoms, and Evan Welsh
2387 (who had nothing to do with causing the bug) found the bug and submitted a
2388 fix; thanks to them both.
2390 * Removed restriction against using EditGame while playing, observing,
2391 or examining on ICS. You still get a warning popup.
2393 3.3, patchlevel 3 -- Sat Sep 16 11:44:05 PDT 1995 Tim Mann
2395 * Bug fix: Going directly from MachineWhite to TwoMachines mode would kill
2396 off the second chess program after Black's first move.
2398 * Added -timeIncrement feature. Thanks to Joel Rivat.
2400 * Deleted code that tries to keep you from observing more than one game,
2401 or observing while playing or examining. There is actually no problem in
2402 doing this, except that every time an update comes in from a different
2403 game than is currently being displayed, xboard fetches the history of the
2404 new game, which may be time-consuming if you are on a slow link.
2406 * Fixed configure so as not to crash when neither lex nor flex is found.
2407 lex or flex is needed only if the user wants to rebuild parser.c. Thanks
2408 to Phil Humpherys for reporting the crash.
2410 * Bug fix: config.h.in used #define instead of #undef for some macros used
2411 in the pty code in childio.c. This causes the code to fail to compile on
2412 some architectures, because the symbols are supposed to be undefined, not
2413 defined to empty, when they are not set in configure. Bug originated in
2414 3.3.pl0 when config.h was introduced. Thanks to Phil Humpherys for report.
2416 * Bug fix: ShowThinking would not show anything when current position had
2417 no move to display in the move window. E.g., if position was created by
2418 LoadPosition or EditPosition.
2420 3.3, patchlevel 2 -- Mon Aug 28 11:11:11 PDT 1995 Tim Mann
2422 * Zippy code was omitted from xboard-3.3.pl1 by mistake; now included.
2424 * For WinBoard, added hint to help file that you may need to turn off
2425 LocalLineEditing while typing dialing commands to your modem.
2427 3.3, patchlevel 1 -- Sat Aug 19 15:13:30 PDT 1995 Tim Mann
2429 * Zippy distribution is no longer separate from regular xboard distribution.
2431 * Deal properly with Show Thinking output from GNU Chess when it is
2432 thinking on its opponent's time. In TwoMachines mode this output is
2433 suppressed to avoid interfering with the output from the machine that is
2434 on move; in other modes it is displayed (including the move that GNU Chess
2435 is predicting the user will make next). GNU Chess produces this output
2436 only if it is built without -DQUIETBACKGROUND defined; this symbol is
2437 defined by default in patchlevels before pl75, but undefined by default in
2440 * Bug fix: Handling of initial board position in move list for wild games
2441 was broken, so wild games could not be observed and adjourned wild games
2442 could not be continued. Thanks to "Maximum Entropy" for the bug report.
2444 * Added feature: algebraic notation now shows "+" indicator for check
2445 and "#" for checkmate, as called for in PGN standard. Thanks to Kevin
2446 Maher for the suggestion.
2448 3.3, patchlevel 0 -- Thu Jul 27 22:21:07 PDT 1995 Tim Mann
2450 * Changed configuration to use a config.h file instead of passing zillions
2451 of -D options on the cc command line.
2453 * Merged a small fix and some updates to the texinfo file from Jochen
2454 Wiedmann. The texinfo file still needs work.
2456 3.2, patchlevel 5 -- Tue Jul 18 20:29:39 PDT 1995 Tim Mann
2458 * Beta test release of xboard only.
2460 * Updated WinBoard code to include new xboard features.
2462 * Added texinfo file from Jochen Wiedmann to the release, but not as the
2463 primary documentation. It needs updating, and the English needs work.
2464 I did make a few improvements, mostly to change incorrect uses of @var to
2465 either @samp or @code as appropriate.
2467 * Merged in code changes to 3.2.pl4beta from Jochen Wiedmann.
2469 * Fixed EditComment; did not pop up window in previous beta.
2471 * Added AutoComment feature.
2473 * Added GameListDestroy to disable the outdated game list popup in cases
2474 where we load a new game file without building a new popup.
2476 * Added yyskipmoves feature to parser.l to speed up building of gamelist.
2478 * gamelist.c wouldn't compile with a non-ANSI compiler. Fixed.
2480 * Change to yy_text handling in patchlevel 3 still had problems. Can't
2481 use AC_DECL_YYTEXT in configure.in, because that defines YYTEXT_POINTER
2482 according to whether the lexer on the current host makes yytext a pointer.
2483 But most people will be using a parser.c that was generated on another
2484 host and shipped with the package.
2486 3.2, patchlevel 4 -- Sun Jun 25 19:13:43 PDT 1995 Tim Mann
2488 * Beta test release of xboard only.
2490 * Added FIREWALLS section to man page.
2492 * Changed -icsport to be a string. Now with the -telnet option,
2493 specifying -icsport "" suppresses the second argument to telnet.
2495 * Added EditTags feature. Removed AboutGame from menu, because EditTags
2496 subsumes it. EditTags suggested by Jochen Wiedmann and first implemented by
2497 him in AmyBoard. xboard implementation is my own.
2499 * Fixed some missing or incorrect prototypes.
2501 3.2, patchlevel 3 -- Sat Jun 3 18:57:38 1995 Tim Mann
2503 * Beta test release of xboard only.
2505 * New version of cmail from Evan Welsh, to fix compatibility problems with
2508 * Added game list feature on Load Game, based on code from Jochen
2509 Wiedmann. Integrated it with cmail.
2511 * Several bug fixes from Jochen Wiedmann, including one to my yy_text
2512 workaround for the difference in the type of yytext between lex and flex.
2514 * Handle clock pause on FICS.
2516 * Suppress clocks in untimed FICS games (time control 0 0).
2518 * Rebuilt configure script with autoconf 2.3. This fixes a bug in
2519 configuring for X11R6, where -lSM -lICE would not be added when needed.
2521 * Fixed inconsistent type declarations on IntSigHandler and
2522 CmailSigHandler. Bug report from Josh Daynard.
2524 * backend.c wouldn't compile with a non-ANSI compiler. Fixed.
2526 3.2, patchlevel 2 -- Tue Feb 7 14:50:30 1995 Tim Mann
2528 * Minor release of both xboard and WinBoard.
2530 * Added recognition of some FICS messages. On the other hand FICS is also
2531 changing some of its messages to match what xboard already recognizes.
2533 * Temporarily went back to using "promote" command on ICS instead of
2534 "a7a8=Q", because FICS doesn't implement the latter yet.
2536 * We now avoid using overlapped I/O on pipes in WinBoard, to make Windows
2537 95 beta 2 happy. This lets WinBoard work with GNU Chess on Windows 95!
2539 * Installed patches from Jochen Wiedmann to coordinate with Amiga XBoard.
2541 * Installed patch to cmail bug in LoadGame from Evan Welsh.
2543 * Bugfix: checkmate and stalemate moves entered with EditGame in ICS mode
2544 were not being handled correctly. Bug was in GameEnds().
2546 * Implemented EchoOn and EchoOff for xboard, using system("stty echo\n").
2547 Now passwords won't be echoed when you connect directly to ICS. Also,
2548 telnet negotiation characters aren't displayed (when possible).
2550 * Implemented more of the telnet protocol. Now connecting to a telnet
2551 server with "-icsport 23" should work even without giving the -telnet
2552 option. The telnet is in "old line-by-line mode".
2554 3.2, patchlevel 1 -- Sat Dec 10 13:50:46 1994 Tim Mann
2556 * This patchlevel released for WinBoard only.
2558 * winboard.c: Fixed ConsoleInputThread(). Needed to change CRLF to LF,
2559 not to CR. This was stopping normal /ics mode from working. Thanks to
2560 Asher Kobin for the bug report.
2562 * winboard.c: Fixed Raw(), EchoOn(), EchoOff(). Now they take effect
2563 immediately, not on the next console read after the one in progress.
2565 * winboard.c: Attempted to make WinBoard work with gnuchessx running
2566 directly on Windows (not remotely via rsh). It now works on NT, but only
2567 if gnuchess is told not to think on its opponent's time ("easy\n" removed
2568 from initString). The problem seems to be that GenerateConsoleCtrlEvent
2569 is not doing anything. On Windows 95 beta 2, we get error messages on
2570 both reading and writing to gnuchessx; I didn't investigate why.
2572 3.2, patchlevel 0 -- Wed Dec 7 13:23:36 1994 Tim Mann
2574 * Thanks to all the beta testers who gave me feedback: Josef Nelissen,
2575 Steve Booth, Evan Welsh, Dima Dakhnovsky, Chris Petroff, Peter Jansen,
2576 Derek Terveer, Michel van der List, Richard Lloyd, Shelly Mistry, and Mike
2577 Lee. Sorry if I forgot anyone. Thanks to Virendra Kumar Mehta for
2578 information about DYNIX/ptx.
2580 * Don't exit on keyboard EOF unless we get two in a row.
2582 * WinBoard only: added -localLineEdit switch to allow turning off local
2583 line editing if you really want to. It is still a bad idea to let the
2584 echoing be done remotely, however; see below.
2586 * Fixed some configure problems on HP-UX. [Steve Booth]
2588 * Fixed (I hope) configure problem on SunOS 5.3/Solaris 2.3. [Josef Nelissen]
2590 * cmail bugfix from Evan Welsh (cmail 3.4).
2592 3.1, patchlevel 9 -- Fri Dec 2 23:54:56 1994 Tim Mann
2594 * Beta distribution only
2596 * Always do local echo/edit of user typing in ICS mode. Doing the echo
2597 downstream may seem nicer in some modes, and it can be hard to turn that
2598 echo off, but the echoed characters can be interleaved with ICS output
2599 and make it impossible to parse correctly. For xboard this involved only
2600 a change to recommendations in the man page, as Raw() isn't implemented.
2601 For WinBoard, removing Raw() made a real difference. Added code in
2602 WinBoard to change /r/n back into /r on keyboard input, as we get the
2603 former when Raw() is not called.
2605 * Do not issue ICS "refresh" command after we start to observe a game
2606 unless we get to the next prompt without seeing a board image. Newest
2607 version of ICS doesn't require this refresh, but old versions around still
2610 * cmail bugfix and small code cleanup in LoadGame, from Evan Welsh.
2612 * Added keyboard accelerators N/P for LoadNextGame/LoadPreviousGame. Evan
2615 * Using "-" on the command line as a filename for loading (saving) games
2616 or positions specifies the standard input (standard output). Alain Picard
2619 * On WinBoard only, a command line option without a leading '-' or '/' is
2620 now taken as the value of -lgf.
2622 * Changed to not use stdin, stdout, stderr as initializers in backend.c;
2623 needed for GNU libc compatibility. You also must build parser.c with flex
2624 (not lex) if you are using GNU libc, to avoid having the same problem
2627 * Changed WinBoard to avoid using "overlapped" input on the console. It
2628 now seems to fully work on Windows 95 beta 2.
2630 * Improved comment popups on WinBoard. Now newlines are handled properly,
2631 and the plain Comment popup window doesn't disappear and reappear when we
2632 step to a new move with a new comment.
2634 * Fixed bugs in detecting the absence of the time and otim commands.
2636 * Added built-in implementation of rcmd protocol to WinBoard. Windows NT
2637 does not implement passing signals through rsh, and Windows 95 does not
2640 * Added -remoteUser option.
2642 3.1, patchlevel 8 -- Mon Nov 28 15:26:07 1994 Tim Mann
2644 * Beta distribution only
2646 * Rearranged ChangeLog file into reverse chronological order to be closer
2649 * Integrated new cmail code from Evan Welsh (including cmail RCS rev 3.2).
2650 Includes a bug fix to TruncateGame.
2652 * Updated ICS address to be chess.lm.com.
2654 * Bug fixes to handling the aftermath of FatalError. Thanks to Chris
2655 Petroff for the bug report.
2657 * Test for remsh before rsh, other fixes for HP-UX. Thanks to Richard
2658 Lloyd. I wasn't able to do all the things he suggested, so there may
2659 still be some rough edges in building on HP-UX. See the FAQ file for hints.
2661 * Bug fix; added missing check for HAVE_SYS_SYSTEMINFO. Thanks to Josef
2662 Nelissen for testing on Solaris 2.x.
2664 * Updated WinBoard to match xboard. (WinBoard still has a few option
2665 dialogs that don't exist in xboard.)
2667 * Changed Hint output to a popup.
2669 * ShowThinking output and move output no longer overwrite each other.
2670 ShowThinking output won't appear if the displayed position is not current.
2671 ShowThinking output in TwoMachines mode made clearer and documented.
2673 * Implemented --enable-ptys and --disable-ptys arguments to configure.
2675 * Fixed Book and Hint code to work over a pty with echo enabled and tabs
2676 expanded to spaces. Thanks to Dima Dahknovsky for the bug report.
2678 * Moved Attention calls from all over xboard to one place, inside
2681 * Added bulletproofing to ShowThinkingEvent.
2683 * Added code to handle "refresh N" boards that come in from ICS properly,
2684 assuming ICS is changed to mark them with a new relation code (-3).
2686 3.1, patchlevel 7 -- Sun Nov 13 22:16:01 PST 1994 -- Tim Mann
2688 * Beta distribution only
2690 * Changed ShowThinking to just show the current best line in the
2691 DisplayMessage area, instead of dumping everything to stdout.
2693 * Installed new cmail (RCS rev 3.1) and cmail.man (RCS rev 1.10), and
2694 changes to cmail code in backend.c, from Evan Welsh.
2696 * Miscellaneous minor fixes.
2698 3.1, patchlevel 6 -- Fri Nov 4 12:53:53 PST 1994 -- Tim Mann
2700 * This patchlevel was not actually released to anyone.
2702 * Updated the pty code to be based on GNU Emacs 19.24, and moved it to a
2703 separate file. It was hard to split out just the pty configuration from
2704 all the stuff emacs does with its custom configure script and .h files,
2707 * Converted from imake to GNU autoconf. This was a serious upheaval.
2709 * Put in code to help trap "error gathering move list" problem reported by
2710 Michel van der List if it recurs. I couldn't reproduce it.
2712 3.1, patchlevel 5 -- Mon Oct 31 21:12:00 PST 1994 -- Tim Mann
2714 * Beta distribution only.
2716 * We now test for checkmate or stalemate in EditGame mode after every user
2717 move, and in LoadGame mode whenever we hit the end of a game without
2718 seeing a PGN end marker. cmail needs an update to deal with this
2719 correctly; Evan promises one.
2721 * Bugfixes in new move generator. Thanks to Mike Lee for reporting one of
2724 * Imakefile was omitted from patchlevel 4.
2726 3.1, patchlevel 4 -- Mon Sep 19 18:19:46 PDT 1994 -- Tim Mann
2728 * Beta distribution only.
2730 * The move generator includes a mate tester. Initially this is used only
2731 by cmail, and even that usage needs further work.
2733 * Wrote a true move generator and used it to replace all the move
2734 disambiguation and legality checking code in parser.l. The move generator
2735 is capable of dealing correctly with en passant and castling availability,
2736 but the rest of the program still does not keep track of this information.
2738 * Bug fix: xboard did not handle "foo has made you an examiner of game 23"
2739 message. Thus you could not use examine features until the next board
2740 came in, showing your new relation to the game. Thanks to POOKIEWOOKIE on ICS
2743 * Added AutoObserve feature. Thanks to Chris Petroff for the idea.
2745 * Added Book feature to use new gnuchess "bk" command. Mike McGann request.
2747 * Redid code to handle missing "time" command in gnuchess, because latest
2748 gnuchess no longer sends a response to this command.
2750 * Eliminated need for -DFLEX. Thanks to Michael Shields (Vladimir?) for
2753 * Added missing code to implement MoveNow in TwoMachines mode.
2755 * Added ShowThinking feature. Thanks to Richard Lloyd for the idea.
2757 * Applied patches from Evan Welsh; some fixes and improvements to the
2760 * Fixed bug in moving from EndOfGame mode to MachineWhite or MachineBlack,
2761 introduced in previous patchlevel. Also fixed related bug in ending a
2762 game in ICS mode; was entering EndOfGame mode instead of IcsIdle.
2764 * Added patch to implement internetChessServerLogonScript flag, from Kevin
2767 3.1, patchlevel 3 -- Wed Sep 7 13:22:07 PDT 1994 -- Tim Mann
2769 * Beta distribution only.
2771 * Merged in new cmail code from Evan Welsh. He added the ability to have
2772 more than one game per message, needed for official IECG matches. I added
2773 the ability to resign or offer/accept/decline a draw in a cmail game.
2775 * Bugfix: invalid -tc option caused segmentation fault; DisplayFatalError
2776 was called too early in initialization. Georges Honore reported this bug.
2778 * Decided to keep EndOfGame mode as an element of the user interface---it
2779 means that a gnuchess game or loaded game has ended, and the user must
2780 explicitly select EditGame to edit it, rather than just being able to
2781 enter more moves freely. But internally there is no longer an invariant
2782 tying this mode to whether the chess program is running.
2784 * Zippy bugfix: Was saving only the final position in the -sgf file when
2785 the game ended by something other than resignation or flag. Also fixed
2786 the longstanding bug that Zippy would think the final board of such a game
2787 was a new game and restart the chess program.
2789 * Now does a better job of faking castling availability in FEN. We still
2790 don't really keep track of it, but now at least we don't say that castling
2791 is still available when the king or rook is not on its home square.
2793 * Bugfix: Initial board of game history for wild games was going through
2794 too much processing, causing us to forget the game length, which is now
2795 needed by ParseGameHistory. This was causing problems with resuming
2796 adjourned wild games.
2798 * Updated ICS host to ics.onenet.net.
2800 * Zippy now accepts challenges where the opponent specified his color.
2802 * Added ZIPPYPASSWORD2 to let operator give commands directly to gnuchess.
2804 * Bitmap directory can include alternative icons now, too.
2806 * Handle "Game * (*) has no examiners" message from ICS.
2808 * Revamped window title and icon name selection.
2810 3.1, patchlevel 2 -- Sun Jun 12 17:16:28 PDT 1994 -- Tim Mann
2812 * "Beta" distribution for Zippy users only.
2814 * Bugfix: common.h was assuming that X11 type Boolean is char, which is
2815 not always true. This might have caused all sorts of obscure bugs!
2817 * Installed new bitmaps from Elmar Bartel as the default. Many thanks!
2818 The old bitmaps can be used by changing the "bitmaps" symbolic link before
2819 compiling xboard, or by using the -bitmapDirectory option at runtime.
2821 * Loading a game that ends with the PGN unfinished symbol ("*") now always
2822 leaves you in EditGame mode.
2824 * Added documentation of -icscomm to man page. Thanks to Maarten Remkes
2825 for the linux script.
2827 * ^C now kills gnuchess as well as xboard. Thanks to Dima Dakhnovsky for
2828 reminding me how to do this.
2830 * Bitmap icon color now indicates player to move. Stuart Cracraft
2833 * Changed piece bitmap flags to have just one flag, which points to a
2834 directory full of bitmaps, instead of a flag for each bitmap. Also
2835 changed bitmap naming convention.
2837 * "Connection closed by ICS" is no longer a FatalError popup. This was
2838 too annoying in the normal case where the user typed "quit".
2840 * Changed default font to 14 pixels instead of 10 points. This seems to
2841 make it close to the size I want it to be on more displays.
2843 * Major mode (GNU Chess, etc.) appears in title bar. Stuart Cracraft
2846 * Bug fix: EditGameEvent, MachineBlackEvent, MachineWhiteEvent, and
2847 TwoMachinesEvent were calling PauseEvent to get out of pause mode, which
2848 now has undesired side effects, such as advancing the display to the
2849 forwardMostMove. It works fine to just set pausing = FALSE instead.
2851 * IcsExamining mode now lets you access ICS edit position commands using
2852 the same popup menus as xboard's EditPosition mode. Thanks to DAV on ICS
2853 for inspiring the idea.
2855 * Corrected test for gcc on HP in Imakefile; thanks to Richard Lloyd.
2857 3.1, patchlevel 1 -- Wed Jun 1 16:25:11 PDT 1994 -- Tim Mann
2859 * Added parser.c.lex and parser.c.flex to the distribution.
2861 * Added HP gcc options to Imakefile, from Mats Nylen.
2863 * EndOfGame mode no longer highlights EditGame mode indicator, because the
2864 modes really do differ. I would like to get rid of EndOfGame mode in the
2865 future, at least as far as users can see.
2867 * Larger %a in parser.l, needed for RS/6000 users.
2869 * Minor improvements to Mail Move error messages.
2871 * When -debug flag is given to xboard, -v is passed to cmail.
2873 * Old Save Style uses "1. ..." instead of "1..." when black moves after a
2874 comment; more like xboard 3.0's actual style.
2876 * New version of cmail from Evan Welsh. Looks for UCB Mail in a more
2877 portable way and has some minor bug fixes.
2879 * Bug fix: Saving a FEN position while in EditPosition mode with black to
2880 play was showing white to play in the saved position.
2882 3.1, patchlevel 0 -- Fri May 20 16:36:15 PDT 1994 -- Tim Mann
2884 * This is the first general release since 3.0, patchlevel 9. Releases
2885 since then have been limited-distribution or beta releases.
2887 * Thanks to my version 3.1 beta testers: Dmitry Dakhnovsky, Ed Hanway,
2888 Richard Lloyd, Mike McGann, Shelly Mistry, Josef Nelissen, Chris Petroff,
2889 Jack Robertson, Michel van der List, Ky Macpherson, Derek Terveer, and
2890 Evan Welsh. Sorry if I've forgotten anyone who gave me feedback.
2894 * Minor cleanup on menu sensitivity code.
2896 * Integrated another even better version of cmail from Evan Welsh,
2897 including some code he supplied in xboard itself.
2899 * A few more fixes to cmail support.
2901 * Automatically update clocks after an ICS "moretime" command.
2903 * Handle ICS automatic examine mode (set examine 1) after a game.
2905 3.0, patchlevel 14 -- Tue May 17 13:41:44 PDT 1994 -- Tim Mann
2907 * Beta test release only.
2909 * Don't suppress prompt on first board of game being examined; otherwise
2910 it looks like nothing happened at all (i.e., like you're lagged).
2912 * Added StopExamining and StopObserving (Chris Petroff suggestion).
2914 * Made Reset do a refresh on ICS. John Chanak's original ICS code for
2915 xboard tried to do this; I finally decided it was a good idea after all.
2917 * Fixed bugs in handling updates that come in while you are pausing in
2918 examine mode. This is pretty tricky to do right.
2920 * Made un-Pausing immediately pop you to the current position. This is
2921 always necessary in examine mode, since the game may have changed under
2922 you; your remembered moves might no longer be right. So I made it do the
2925 * Took Detach Examine mode back out...used Pause mode for this instead!
2927 * Put in a trap for the GNU Chess bug of printing an Illegal Move message
2928 when its own hint move is illegal.
2930 * Attempted to fix a Zippy bug; bogus "exited unexpectedly" messages after
2931 it checkmates its opponent. This involved adding an argument to GameEnds
2932 to say who says it ended (ICS, GNU, etc.) and taking different actions in
2933 different cases. Unfortunately, this just restored an older Zippy bug, where
2934 Zippy restarts gnuchess when it gets the board with the final position,
2935 because GameEnds still puts xboard in EndOfGame mode. Sigh.
2937 * We now capture elapsed time on last move when getting game history.
2938 (Josef Nelissen bug report)
2940 * Rewrote code to redisplay last file title so it really works.
2942 * Fixed bug in oldSaveStyle.
2944 * Larger %a and %o were needed for lex.
2946 3.0, patchlevel 13 -- Mon May 16 16:26:22 PDT 1994 -- Tim Mann
2948 * Beta test release only.
2950 * FatalError popups stay on the screen now. If the error is really fatal,
2951 all functions are disabled, and the program exits when you press OK.
2953 * Redisplay last file title when using Load (Next/Previous/Same) Game.
2955 * Zippy understands new match challenge message format on ICS.
2957 * Added Revert command.
2959 * When examining a game on ICS, < > buttons do ICS backward/forward
2960 commands, unless you set the Detach Examine option. Thanks to Dima
2961 Dakhnovsky for the idea.
2963 * Fixed various minor problems in cmail mode.
2965 * cmail generates the tags now. New version of cmail from Evan Welsh.
2967 * cmail mode won't let you do MailMove unless the currently displayed
2968 position is exactly one move past the end of the game you loaded.
2970 * Fixed building of man pages in Imakefile
2972 * Updates to INSTALL file
2974 3.0, patchlevel 12 -- Sat May 7 21:10:03 PDT 1994 -- Tim Mann
2976 * Beta test release only.
2978 * Brought man page up to date.
2980 * Added Shift+R to resign from keyboard.
2982 * Some items on Action menu available in GNU Chess mode now.
2984 * Revamped Action menu.
2986 * Reordered functions in backend.c as a small step toward reorganizing
2989 * Generate TimeControl PGN tag.
2991 * Get type of ICS game (e.g., rated blitz) and save in PGN tags.
2993 * Bug fix: Clocks were not redisplayed when entering EditGame mode.
2995 * Bug fix: Clocks were not being redisplayed after loading a game file
2996 with -td 0, so they could show the wrong color active.
2998 * Bug fix: Chess programs would be killed and match mode would exit
2999 prematurely when loading a PGN game fragment ending with "*".
3001 * ICS command "sposition" no longer confuses xboard.
3003 * Integrated new version of cmail (with support code in xboard) from Evan
3006 * Added TruncateGame, MoveNow, RetractMove, and QuietPlay.
3008 * Bug fix: switching between MachineWhite and MachineBlack was not calling
3009 Attention(). Reported by Dino Dini.
3011 * More improvements to INSTALL and Imakefile.
3013 * Pack moves into 79 character lines in PGN output. We don't generate
3014 check indications, and we always break the line before the result,
3015 so this is not quite PGN export format.
3017 * Use FEN tag in PGN.
3019 * Improved finding and counting of game starts in save files.
3021 * Negative position or game numbers in -lpi/-lgi mean to seek to that byte
3022 offset. Hook for possible future features, not in man page.
3024 * Detect and handle absence of either "time" or "otim" commands in
3027 * Don't use "promote" command to ICS anymore.
3029 * Handle switching sides and taking back moves on FICS.
3031 * Handle flip state flag in style 12 board.
3033 * Handle examine mode on ICS.
3035 * Improved error popups for various kinds of illegal moves.
3037 * Suppress unasked-for hints from gnuchess (which it generates in post
3040 * Load/save position functions use FEN. Old style also supported.
3042 * Added detailed error messages if loading a bitmap file fails.
3044 * Small board has 2-pixel lines between squares instead of 3-pixel.
3046 * Added OldSaveStyle and AboutGame.
3048 * Renamed ForceMoves to EditGame.
3050 3.0, patchlevel 11 -- Tue Sep 21 15:25:36 PDT 1993 -- Tim Mann
3052 * The following changes were present in xboard 3.0, patchlevel 11, but the
3053 first group did not make it into WinBoard 3.0 until later. xboard
3054 3.0.pl11 was a limited-distribution release only, mostly to Zippy users.
3056 * Man page minor fixes.
3058 * Added a missing file close.
3060 * Removed automatic error popdown on Reset, which was destroying some
3061 error messages before they could be read.
3063 * Fixed char vs. unsigned char warnings on bitmaps.
3065 * Use ICS board style 12. Some improvements to ICS parsing.
3067 * Comment window is now labelled with the move the comment is on, and
3068 comments don't pop down when you step to the next move.
3070 * Save files now in PGN format.
3072 * Support for loading PGN files. PGN tags pop up when a PGN game file
3075 * More info in INSTALL and Imakefile about building for Suns (and
3078 * WinBoard 3.0 patchlevel 11 split off from an early version of xboard
3079 3.0 patchlevel 11, so it does not have all the features of that
3080 patchlevel. The following changes made it into both xboard and
3083 * Made Comment dialog non-modal in WinBoard.
3085 * EndOfGame mode is now more transparent. It looks like ForceMoves
3086 mode except that there is no chess program running.
3088 * Small bug fixes in clock management. Most noticeably, pausing when
3089 it is gnuchess's move now works as documented (again).
3091 * Add minimal support for -icscomm option. Not documented yet because
3092 I haven't sorted out the issues with setting the tty modes on the comm
3093 port device, or with locking it properly. But it's usable by wizards.
3095 * Don't restart the chess program upon Backward event from EndOfGame mode.
3097 * Suppress extra prompt after ICS sends us a board.
3099 3.0, patchlevel 10 -- Sat Sep 11 18:44:03 PDT 1993 -- Tim Mann
3101 * Beta test release only.
3103 * Zippy now plays chess. zippy.c and zippy.h are still not included
3104 in the standard distribution, but are available on request.
3106 * Switched to using style 12 on ICS.
3108 * Updated man page, and documented use of XBoard*form.translations to
3109 add more shortcut keys.
3111 * Added shortcut keys "d" to claim/offer/accept a draw, and "t" to
3112 call flag. Suggested by venu on ICS.
3114 * More explicit instructions in INSTALL file.
3116 3.0, patchlevel 9 -- Tue Sep 7 14:02:00 PDT 1993 -- Tim Mann
3118 * General release, minor update to 3.0.pl8.
3120 * Loosened checking on whether it's okay to start a move, to satisfy
3121 ICS ultra-blitz players. Now we don't check whether it's your turn
3122 until you let go of the piece.
3124 * Parser now recognizes "+-+" as meaning the game ended in a draw.
3126 * Got rid of S_NONE symbol, which seems to conflict with some symbol
3129 * Tweaked the man page. Clarified that there is currently no way for
3130 two people running copies of xboard to play each other without going
3131 through the Internet Chess Server.
3133 * Fixed a bug in color name conversion. Asking for two different
3134 colors whose names were the same in the first four characters would
3135 get you two copies of the first one. Thanks to Volker Zink for the
3138 * Improved confusing Usage() message.
3140 * Added a bunch of Sun information to the Imakefile and INSTALL file.
3141 Thanks to Ed Hanway, Arik Klingensmith, and others who responded.
3143 * Test for defined(WIN32) instead of !defined(unix).
3145 * Avoid using (void *) type with non-ANSI C compilers. Thanks to
3146 James Altucher for the bug report.
3148 3.0, patchlevel 8 -- Thu Sep 2 12:23:01 PDT 1993 -- Tim Mann
3150 * Note: Patchlevel 8 was the first non-beta release of xboard 3.0
3152 * Added cmail to distribution. Contributed (and still maintained) by
3155 * Bug fix: -queen option wasn't initializing menu check. Reported by
3158 3.0, patchlevel 7 -- Thu Aug 26 13:23:24 PDT 1993 -- Tim Mann
3160 * Sent WinBoard 3.0.pl7 to Torre on ICS
3162 * Added parser.h to hold the interface to parser.l
3164 * Upgraded COPYING file and copyright notices to GNU GPL version 2.
3166 3.0, patchlevel 6 -- Tue Aug 24 15:16:13 PDT 1993 -- Tim Mann
3168 * We no longer display intermediate positions or intermediate comments
3169 while loading a game file with -timeDelay 0 or loading an opening to
3170 start up a -matchMode game.
3172 * Loading an empty game from an xboard save file now gives a status
3173 message "No moves in game" instead of an error popup saying "Game not
3176 * Added comment.awk to distribution.
3178 3.0, patchlevel 5 -- Tue Aug 17 16:45:54 PDT 1993 -- Tim Mann
3180 * Bug fix: xboard would crash if it couldn't get all its colors; now
3181 it switches to monoMode instead. Also, xboard was trying to convert
3182 color resources even when using a b/w display. Reported by Larry
3185 * Bug fix: Declared fields of TimeMark as signed so that we get signed
3186 instead of unsigned arithmetic. SubtractTimeMarks was breaking on
3187 Alpha AXP (which has 64-bit longs) with old declarations. Reported by
3188 Michel van der List.
3190 * Bug fixes: Keyboard accelerators now work after EditComment window is
3191 popped down. Iconize keyboard accelerator now works even if xboard
3192 was started with -iconic flag and later deiconized.
3194 * Bug fix: The routine that tests whether a move is illegal because it
3195 would leave you in check was not handling e.p. captures properly.
3196 Reported by Patrick Surry.
3198 * Bug (?) fix: Was adding time to clocks at time control even when
3199 loading a game file. Actually it's not entirely clear how time
3200 controls should be dealt with when some moves are loaded from a file
3201 or clicked in with ForceMoves. For now ForceMoves mode does add the
3202 time (because it can be used to change moves during a live game), but
3203 LoadGame mode does not.
3205 * Updated usage message.
3207 * Previous attempted fix to matchMode had broken TwoMachines mode and
3208 generally needed more work. Also simplified command line interface to
3211 3.0, patchlevel 4 -- Thu Aug 5 14:17:18 PDT 1993 -- Tim Mann
3213 * Thanks again to the beta testers listed for 3.0 patchlevel 3, and also
3214 Desnogues, Steve Cariglia, Niklas Engsner, Mark Silver, and Roger Rowe.
3216 * Reorganized man page, splitting OPTIONS into subsections.
3218 * matchMode was very broken; fixed.
3220 * Changed convention for turning off command line options from --opt
3221 to -xopt, to be less inconsistent with GNU standards. Also changed
3222 the long command line options to take True/False arguments like
3223 resources; seems to make more sense this way.
3225 * Added AlwaysQueen option -- suppresses promotion dialog and always
3226 promotes to a queen if you move a pawn to the last rank. Has no
3227 effect on gnuchess (or your ICS opponents!) -- they can still
3230 * Subtracted an extra fudge term when determining how wide message and
3231 title widgets should be. This fixes a problem some beta testers had.
3232 Wish I knew why it's needed.
3234 * Bugfix in parser; symptom was that you couldn't do LoadGame after
3235 observing a game on ICS.
3237 * Bugfix in Forward; didn't work after game ended while Pause was turned on.
3239 * Removed bogus execute bits on .h files.
3241 * Use REMOTE_SHELL and TELNET_PROGRAM definitions.
3243 * MachineWhite and MachineBlack now work from TwoMachines mode.
3245 * Popping down an error message with the [ok] button was not turning off
3246 the errorUp flag, so the next move would cause xboard to try to pop it
3247 down again, resulting in a wild memory reference and sometimes a crash.
3249 3.0, patchlevel 3 -- Tue Aug 3 17:40:27 1993 -- Tim Mann
3251 * Thanks to my beta testers: Patrick Surry, Takuya Kojima, Robert J. Luoma,
3252 Chris L. Petroff, Richard K. Lloyd, Michel van der List, Craig Metz,
3253 Antoon Frehe, Simon Clift, Shelly, Eric Peterson, Christopher Mitchell,
3254 Martin Koch, Ed Hanway, Steve Booth, Udo, Ken Hobday, and Joseph Duhamel.
3256 * Improved error messages for trying to move the wrong color pieces or
3257 to move when it's not your turn.
3259 * Special code for monoMode on 1-bit displays now understands displays
3260 where 1=white and 0=black.
3262 * Declare getenv() if <stdlib.h> not included; avoids a compiler warning.
3264 * Documented borderXoffset and borderYoffset.
3266 * Added -titleInWindow option for use with X window managers that
3267 don't let us set the title in the window banner.
3269 * Fixed error message printing in WinBoard; system error messages no
3270 longer appear as numeric codes.
3272 * The error message popup is now non-modal; you don't have to press the
3273 [ok] button before you can do something else. In addition, the popup is
3274 positioned so that it doesn't cover up the board (too much), and making a
3275 move or otherwise clicking on the board pops it down. (Not implemented in
3278 * You can now call your opponent's flag in ICS mode by clicking on his
3281 * Fixed minor bugs in -flipView option and documented exactly how xboard
3282 decides which way to flip the view.
3284 3.0, patchlevel 2 -- Fri Jul 30 22:20:23 PDT 1993 -- Tim Mann
3286 * Added Autosave to Options menu. Would be better to have Save
3287 Options dialog as in WinBoard, but this was quick to do and gives the
3288 most-needed functionality.
3290 * Changed "Reload Game" on menu to "Reload Same Game".
3292 3.0, patchlevel 1 -- Thu Jul 8 21:22:59 PDT 1993 -- Tim Mann
3294 * Sent a copy of patchlevel 1 to Patrick Surry to beta-test.
3296 * Added -cmail option that sets appData.cmailMode. Currently a no-op.
3297 In the future this may set special modes for use by the cmail script
3298 for playing chess by email.
3300 * Added LoadNextGame, LoadPreviousGame, and ReloadGame to File menu.
3301 ReloadGame suggested by Patrick Surry.
3303 * Added -flipView command-line option. Suggested by Patrick Surry.
3305 * Fixed bugs in parser.l: (1) Pattern for "# xboard game file ..."
3306 needed to match to end of line. (2) Start of a new file was not matching
3307 the ^ start-of-line character. The fix for this is a kludge.
3309 * Made game counting code in LoadGame more robust, and made LoadGame
3310 able to detect the end of a saved partial game (by noticing the start
3311 of the next game) in game files created by XBoard itself. We don't
3312 try to find the start of the next game that way in other kinds of game
3313 files, because the only way I can think of to do that is to look for
3314 another move #1, and that technique gets too many false hits.
3316 * Fixed recently introduced bug in LoadGame when game starts with a
3319 3.0, patchlevel 0 -- Fri Jun 25 14:17:17 PDT 1993 -- Tim Mann
3321 * Changes in this patchlevel were too numerous to list. Larger ones are
3324 * Added a popup dialog to enter and edit comments. Inspired by some
3325 code from Patrick Surry. Changed the normal read-only comment popup
3328 * Added ICS init script feature from Karl Schwamb.
3330 * Added some ESIX fixes and OMIT_SOCKETS ifdef option, from Kayvan Sylvan.
3332 * Revamped code to allow use of flex instead of lex on parser.l.
3333 Using flex requires adding -DFLEX to defines in Imakefile.
3335 * Source code is split into front end (xboard.c), which knows about X
3336 and Unix, and back end (backend.c), which knows about chess, gnuchess,
3337 and the ICS. There is also a front end for Windows NT.
3339 * Boolean command line options now use "-foo" to turn on and "--foo"
3340 to turn off instead of "-foo true" and "-foo false". [Later -xfoo;
3343 * Added menu commands to control autoflag, bell, and coords options.
3345 * User interface has a new look: (1) Menu bar instead of array of
3346 buttons. A few very commonly used features have small buttons in
3347 addition to being on the menus. (2) Large font for clock. (3) Pop-up
