1 ChangeLog for XBoard/WinBoard
2 * 06/27/20ß4: added simple icsEngineAnalyze for xboard
4 * 06/26/2004: added icsEngineAnalyze for winboard: Analyze observe games
5 with a chessprogram on a Internet Chess Server (ICS)
7 * 02/12/2004: Bugfix ICS interaction console crashed while chess
8 engine starting and user type in some stuff. We are wait now to finish
11 * 02/11/2004: Winboard: Added color lines for the ics interaction
14 * 02/09/2004: Added mousewheel support for winboard. Play moves
15 backward and forward with the mousewheel.
17 xboard/WinBoard 4.2.7 -- Fri Nov 28 13:36:00 PST 2003 -- Tim Mann
19 * 11/26/2003: In WinBoard, setting the -debug flag now logs ICS output
20 to WinBoard.debug too. (This isn't needed in xboard because ICS
21 output already goes to stdout, so it's easy to capture along with the
22 debug output on stderr.) This was issue #280 in the ToDo file.
24 * 11/23/2003: Cleaned up some minor problems in cygwin.mak. Thanks to
25 Hans Werner Strube for the problem report.
27 * 11/23/2003: Updated the default list of chess servers in
28 winboard/defaults.h. Deleted two that appear to be dead and added a
29 new one that is active.
31 * 11/19/2003: Swapped icon_white.bm and icon_black.bm in XBoard.
32 Hopefully this will get them the right way around by default on more X
33 window managers. I wish I understood this better.
35 * 11/18/2003: Implemented a simple 32-bit random number generator for
36 WinBoard, replacing the Windows rand(), which ranges only up to
37 0x7fff. Formerly on Windows, only zippy.lines sayings that started in
38 the first 32767 bytes of the file could ever be used. This was issue
39 #505 from the ToDo file.
41 * 11/16/2003: The xboard man page and info files are now built from a
42 common set of texinfo source files, and the xboard man page now covers
43 cmail as well. Formerly, ever since the texinfo file was first
44 contributed to the project, it was separate from the man page and the
45 two files had to be updated in parallel, making for a maintenance
46 nightmare. To make combining the files possible, I took the Perl
47 script "texi2man" from the GNU Units project and added support for a
48 larger subset of the texinfo markup language. I then carefully
49 compared the old man page and old texinfo file to make sure the latest
50 and clearest words survived into the new combined texinfo file. It
51 would be great to merge in WinBoard's help file too, but that's a
52 larger project. It would have to be heavily conditionalized to
53 deal with differences in features between XBoard and WinBoard.
55 * 11/15/2003: Cleaned up and applied a small patch from Daniel
56 Mehrmann, to stop overly long PVs in thinking output from causing a
57 buffer overflow crash in backend.c.
59 * 11/5/2003: When a chess engine sends a "telluser" command (including
60 the cases where "tellall" or "tellopponent" acts like telluser), the
61 information now goes into a nonmodel popup that is automatically
62 dismissed when the user clicks anywhere on the board. This fix is
63 more significant on WinBoard, where formerly you got a fully modal
64 dialog that had to be dismissed by clicking on OK before anything else
65 could happen. The bug was issue #406 in the ToDo file.
67 * 11/1/2003: Removed email addresses from this file to reduce spam
68 load, as it gets linked to from the Web.
70 * 11/1/2003: Updated READ_ME and winboard/READ_ME.txt.
72 * Modified xboard and winboard makefiles to be able to build the
73 project in the new combined directory structure.
75 * Applied a small security fix to pxboard, from Martin Maeok.
77 * Fixed a bug in the game list dialog. The change in 4.2.6 to opening
78 games in text mode (meant to avoid getting extra \r's into comments)
79 caused a new bug in determining seek offsets when parsing a game file
80 to form the game list. Also, the change was incomplete; on some code
81 paths games were still being opened in binary mode. Thanks to Lenik
82 Terenin for reporting the offset bug. I've now gone back to always
83 using binary mode when reading game files, and I've fixed the comment
84 bug by adding code to remove \r's from parsed comments explicitly. I
85 still use text mode for writing game files so that games written by
86 WinBoard will have Windows-style line endings.
88 * Fix for minor bug in WinBoard installer. If you chose a non-default
89 destination directory, the default directory was still used for a
90 couple of unimportant things, namely setting the App Paths registry
91 keys (unused by WinBoard) and trying to copy the existing WinBoard.ini
92 file to WinBoard.old. I inherited this bug from the InstallShield 5
93 sample template. Thanks to "l.d." for noticing the incorrect keys.
95 * Patch from Chris Priest: when two engines are being run through rsh,
96 avoid reusing the same stderr port for both. I'm not sure why this
97 should be needed, but it's harmless, at least.
99 * Bugfix: The kludge to deal with old engines that give an error
100 message because they don't know the "st" command was too sloppy; it
101 could hit on an "st" substring anywhere in an error message. GNU
102 Chess 4 is the only engine I know of where the kludge was needed, so I
103 changed the kludge to match a longer, more GNU-specific string.
105 * Changed the WinBoard self-extracting installer to choose a unique
106 temporary subdirectory name within the Windows temp directory instead
107 of always putting wb-setup directly in temp. Besides being better
108 practice, this avoids the need to deltree wb-setup first, which
109 occasionally alarms someone who thinks that deltree is only used by
110 trojans to delete all your files. (Yes, I'm serious.)
112 * Fixed a bug where FICS-style "wild/0" strings were not parsed as the
113 proper wild type. The "/" was not being skipped.
115 * Fixed a WinBoard bug where temporary files created by game
116 copy/paste were being created in the root directory of the current
117 drive instead of the TMP directory and were not always deleted on exit.
119 * Fixed a small bug in winboard.c's ErrorDialog() function. Thanks to
120 "Ron" (no last name given). The bug might have caused a problem when
121 pressing OK or Cancel in an error dialog when more than one error
122 dialog was being displayed, but I'm not really sure.
124 * Removed a hack that worked around a bug in very old versions of
125 Crafty, where it would sometimes reply "illegal move" to a "."
126 command. The hack kept us from recognizing real illegal move messages
127 in analyze mode from engines that don't respond to the "." command.
128 Thanks to Fabien Letouzey for the report.
130 * Fixed a bug in the xboard version of GetDelayedEvent. It would
131 return the most recently scheduled event even if it had already fired.
132 This caused at least one visible error: in -ics -xreuse mode, starting
133 the engine again and seeing another "feature done=1" would re-run the
134 initialization code in InitBackEnd3, including the code that opens the
135 connection to ICS. The WinBoard version didn't have this bug. Thanks
136 to Bob Hyatt for the bug report.
138 * The promotion popup for ICC wild 26 (giveaway) now includes King.
139 Thanks to Fredrik Josefsson for the bug report.
141 * The first game in a file (or being pasted from the clipboard) can
142 now start with a bare move -- no PGN tags, no move number "1", etc.
143 Suggested by Shane Harrelson. One could imagine taking this farther
144 and accepting something like "e4 e5 1/2-1/2 d4 d5" as two games, but
147 * Bug fix: xboard didn't really accept a paste of multiple games,
148 contrary to what I wrote when adding the feature to WinBoard in
149 4.2.4. Now it works in both.
151 * Fixed generic start/end of game messages to work on chess.net, where
152 they put ratings in parens after the player names.
154 * Updated config.sub and config.guess to newer versions from
155 automake-1.4p5-2. This makes configure work with MacOS X + X11.
157 * Bugfix: when examining a game fragment on FICS where black plays
158 first, don't show two "(0:00.000)" times on the initial "none" move.
160 * If TestLegality is on and one of the engines makes an illegal move
161 in TwoMachines mode, it forfeits immediately. Formerly the game would
162 get stuck at that point and the engine that made the illegal move
163 would eventually lose on time.
165 xboard/WinBoard 4.2.6 -- Fri Feb 1 22:26:31 PST 2002
168 Another small bugfix release.
170 * Put in a small change from Alexander Mai to allow xboard to build in
171 an OS/2 EMX environment.
173 * Fix WinBoard-only bug where editing a PGN file with comments would
174 insert more \r characters before the \n after every Load/Save cycle.
175 For some unknown reason we were reading the files in "rb" mode but
176 writing them in "a" mode, so we kept the \r characters on reading and
177 added an extra one on writing. Fix: change the "rb" to "r". Thanks
178 to Joel (last name not given) for the bug report.
180 * Put the arguments to rsh/remsh in the right order for better
181 portability. Thanks to Michael Kalisz.
183 * FreezeUI is now implemented in WinBoard; it was previously only
184 implemented in xboard. This function prevents the user from entering
185 moves or other commands while we are waiting for an engine to
186 initialize itself. Implementing it fixes a bug where the user could
187 start a game (etc.) during feature negotiation. One of the symptoms
188 of this bug was that we could send "new" one or move moves *after* the
191 * Fixed some handle leaks (WinBoard only), including a nasty one that
192 leaked one handle per command sent to ICS. Thanks to several folks
193 who helped characterize the bug and tried to look for leaks.
195 * We now install and look for the info file in ${prefix}/share/info
196 instead of ${prefix}/info. The latter is still the default in
197 autoconf, but the former is currently used in Red Hat Linux and
200 xboard/WinBoard 4.2.5 -- Sat Dec 15 11:42:51 PST 2001
203 * Changed the bundled GNU Chess 5.02 in the WinBoard package to
204 include a much smaller book and to use much less hash table space by
205 default (8 MB transposition table, 0.5 MB pawn evaluation table). The
206 large book included with 4.2.4 made the WinBoard download too big for
207 some people, and the default hash tables were larger than the
208 available physical memory on some people's computers. I built the
209 small book by running Crafty's "small.zip" book line collection
210 through a Perl script that makes it look enough like real PGN games
211 that the GNU Chess book builder will accept it. The script and some
212 minor patches to GNU Chess 5 are available in the WinBoard source
213 distribution and at http://www.tim-mann.org/gnuchess.html.
215 * Fixed a bug in the code that deals with engines that complain that
216 "time" and "otim" are illegal moves. This was a new bug in 4.2.4.
218 * Revamped the implementation of ToStart in analysis mode. Formerly
219 there was some ill-conceived code that would try to get back to the
220 start of the game by doing a "new" command (and all the followup
221 commands that requires) while remaining in analysis mode. This is
222 problematic for engine authors to support, though it works with
223 Crafty. This code was trying to solve the problem of ToStart being
224 slow because the engine would try to start an analysis after every
225 "undo" command all the way back to the start. But ToEnd already had a
226 much better solution to this problem, and now ToStart does the same
227 thing: we exit from analysis mode and enter force mode instead,
228 make/unmake moves to get to the end/start of the game, and then
229 reenter analysis mode.
231 * Formerly, Zippy could try to start playing a game before the engine
232 was initialized; that is, during the initial timeout for protover 1
233 engines, or before "feature done=1" for protover 2 engines. We now
234 wait until the engine is initialized before connecting to ICS, which
235 fixes this in the common case. If you turn off engine reuse for
236 multiple games (that is, if you give the -xreuse option), there could
237 still be problems; see item 503 in the ToDo file. Thanks to Dieter
238 Buerssner for the bug report.
240 * Bugfix: All WinBoard versions since the merge with WinBoard Plus
241 (but not xboard) have had a bug in changing the PeriodicUpdates,
242 PonderNextMove, and ShowThinking options from the menu. The bug
243 mostly just caused changing these options during a game to not take
244 effect until after the next reset. For TwoMachines games, though,
245 changing PonderNextMove just before the game would take effect
246 immediately for the second engine but not until the next game for the
247 first engine. Thanks to Koundinya Veluri for the bug report.
249 * Bugfix: In 4.2.4, we sometimes got confused when trying to leave and
250 reenter analyze mode. One symptom was that Analyze File did not work.
251 Thanks to Igor Syry for the bug report.
253 xboard/WinBoard 4.2.4 -- Sun Dec 9 14:56:30 PST 2001
256 * WinBoard now includes GNU Chess 5.02 in place of GNU Chess 5.00.
258 * WinBoard's PasteGameFromClipboard will now handle a paste with
259 multiple games in it, popping up the game list dialog. xboard
260 already did this. Suggested by Robert Gerstman.
262 * We now use the "clearboard" command on ICC where appropriate.
264 * Bugfix: don't generate a bogus "variant normal" command to an engine
265 for the loadable ICC wild types that we internally flag as
266 VariantLoadable. Also clarified the message that Zippy sends when
267 declining such wild games -- it can't deal with the possibility of
268 loading an arbitrary position into the game. Thanks to Dieter
269 Buerssner for reporting the problem. It would be nice to be able to
270 actually play these wild types some day; presumably there would have
271 to be an option to either send "loadgame" with a specified position,
272 or to deal with an opponent sending it.
274 * If we get a holdings message from ICS when we thought we were
275 playing normal chess, we now try asking for a move list so that we can
276 find out from the header what's really happening. Formerly we guessed
277 bughouse in this case. Response to a comment from Gian-Carlo
280 * Fixed two longstanding bugs in the clock code. These affected only
281 play between a user and a local engine, or between two local engines,
282 not ICS play. (1) The last fractional second used by a player before
283 moving and virtually pushing his clock was being charged to his
284 opponent instead of to him. (2) The time and otim commands were being
285 sent to an engine before the (buggy) fractional second update was
286 done. The second bug was pretty harmless in itself, but the first one
287 was serious. Many thanks to Peter Rosendahl for carefully diagnosing
288 and reporting these bugs!
290 * Changed WinBoard timestamp key. Nothing is changed other than the
291 key and a recompilation. ICC may phase out the old key soon; if they
292 do, you'll need to use the timestamp.exe from WinBoard 4.2.4 or later
293 to connect to chessclub.com.
295 * Fixed an xboard-only bug where most dialogs would not take keyboard
296 input unless the mouse was actually over the dialog, even if the
297 dialog window had focus. Thanks to Jason Varsoke for the bug report.
299 * Bugfix; Remember to send time and otim commands to engine before
300 sending playother. Thanks to Bob Hyatt for the bug report. Also
301 fixed a bug where time and otim were sometimes sent even with feature
304 * Added small patches from Wilkin Ng that are meant to fix a crash in
305 CopyGameToClipboard and a "can't unlock clipboard memory" error in
306 PasteTextFromClipboard, under Windows 2000.
308 * Changed cygwin.mak to not use -mno-cygwin. In other words, it now
309 uses cygwin1.dll instead of the mingw libraries. This works around
310 bugs in fileno() and stat() that I encountered in mingw. (fileno
311 seems to always return 0. stat fails because the library routine uses
312 a different definition of struct stat than the header files provide.)
313 Thanks to Robert Gerstman for reporting the symptoms these bugs caused
314 when WinBoard was compiled with Cygwin.
316 * Added -showButtonBar option. This lets you delete the << < P > >>
317 buttons and thus widen the message widget a bit.
319 * Added code to address a very obscure bug. If an engine dies and
320 needs to be restarted while in one of the analyze modes, it was not
321 getting put back into analyze mode. This bug should not really ever
322 have gotten tickled unless reuse was turned off and the engine sends
323 game end commands (such as 1-0) when a game ends by rule while in
324 analyze mode. The next version of the protocol spec will say that
325 engines should not do that, but version 2 and earlier didn't address
328 * We now use the FICS "iset ms 1" feature to get times in ms instead
329 of seconds. Thanks to DAV for email telling me about this feature.
331 * Changed clock display to show tenths of seconds for 9.9 seconds and
332 less, instead of 0.9 seconds and less as before.
334 * It has been discovered that Zippy can play simuls on ICC (but not on
335 FICS). If you arrange for Zippy to send the ICC command "simulize" in
336 the -zippyGameStart string, it will accept additional games while
337 playing. Zippy will use the same engine for every game, so whenever
338 it switches opponents, the engine's state will be reset with the "new"
339 command. This will of course weaken its play, so don't enable simuls
340 if you want your engine to have the highest possible rating. Zippy
341 was never designed to work with simuls; it just works by accident, and
342 it hasn't been tested much. So please report any bugs you notice, but
343 don't expect them to be fixed rapidly. Thanks to Paul McGuire for
344 noticing that this works.
346 * Bugfix: Suppress the direct command to engine popup if there is no
347 engine. In WinBoard this case used to cause a crash. Thanks to
348 "Dargon" for the bug report.
350 * Bugfix: formerly we did part of the engine initialization for the
351 very first game too soon, before feature negotiation. One result of
352 this is that engines would never get the "ics" command for the first
355 * Lengthened timeout to detect protocol version 1 chess engines to 10
356 seconds. This should reduce problems with protocol version 2 engines
357 that are slow to initialize missing the timeout and not getting a
358 chance to send their feature commands before the first game starts.
360 * Klaus Friedel says that adding a short sleep to WinBoard after
361 starting a new chess engine solves a problem that occurs under Windows
362 2000, in which engines sometimes don't see the initial command(s) from
363 WinBoard and hang. I don't understand how that can happen, but the
364 sleep is harmless, so I've put it in. Others have also reported what
365 may be the same problem, so hopefully this will fix it for them too.
367 * Bugfix: editing the Result field in EditTags will no longer cause a
368 later crash. Thanks to DAV for a clear bug report that let me
369 reproduce the problem.
371 * ICC wild 28 is now recognized as shatranj, but it is not supported.
372 You might be able to play it by turning off Test Legality.
374 * Formerly we would always turn off "feature time" if the engine
375 printed an error message with the string "time" or "otim" in it; now
376 we do that only if the message comes before the engine makes its first
377 move. This change is useful because some engines spew a lot of bogus
378 error messages about commands they don't fully parse, so something
379 like "result 0-1 {White lost on time}" could generate such a message.
380 Engines shouldn't do that, but if they do, mysteriously turning off
381 "feature time" is not a good way to react.
383 * Fixed an infrequently occurring Zippy bug: formerly, resuming from
384 adjournment by position (that is, with GetMoveList turned off) or
385 starting/resuming a wild game (nonstandard starting position) would
386 try to set up the position without putting the engine into force mode
387 first. That was probably tolerated by most engines, but if the
388 position was black-to-play and the engine hadn't set feature
389 setboard=1, then the fake "a2a3" move (which we use as a kludge to get
390 black to be on move before sending the edit command) would appear to
391 be a real move, and the engine might reply to it! This bug could also
392 be seen when trying to use Zippy to play a simul -- something that
393 Zippy was never designed to support, but which seems to mostly work
394 anyway. Thanks to Paul McGuire for sending a WinBoard.debug file that
395 showed the bug occurring. Some other cases of resuming adjournments
396 or starting games from nonstandard positions may have been broken too;
397 I think I've straightened out the problems.
399 * Agreeing to a draw in the human vs. local engine case formerly did
400 not work if the human offered first; now it does. A human's
401 unsolicited offer is considered valid until he makes another move.
402 Thanks to Bruce Moreland for the bug report.
404 * Bugfix: We used to look for just "fr" in Event tags or strings from
405 ICSes to recognize Fischer Random games. This caused a lot of false
406 matches. Now we look for "wild/fr" instead, which is what FICS uses.
408 * Bugfix: Clicking on a move in the MoveList window only updated the
409 displayed position; if a chess engine was active, its state was not
410 updated. Thanks to Alejandro Dubrovsky for the bug report.
412 * Bugfix: The "resign" command from engine to xboard formerly did not
413 work in ICS (Zippy) mode.
415 * Bugfix: Formerly we would register a garbage premove if the user
416 clicked on a piece, then clicked on an edge or outside the board. Now
417 such an errant click is ignored.
419 * Bugfix: GameEnds would send "exit" to an engine in analyze mode even
420 if we did not actually want to leave analyze mode.
422 * Bugfix: "feature pause" was being rejected. We don't currently use
423 it, but that is no reason to reject it. Thanks to Gian-Carlo Pascutto
426 * Bugfix: when "partner" needed to be sent both to ICS and the engine,
427 Zippy was erroneously sending the ICS prefix character to the engine
428 too. Thanks to Gian-Carlo Pascutto for the bug report.
430 * Zippy now declines challenges when the engine is not yet ready to
431 play again, instead of ignoring them. This is needed so that the
432 server will let the opponent repeat the challenge. It might be better
433 to remember such challenges and accept them when the engine is ready,
434 but that would be a bit more complicated to implement.
436 * Bugfix: Zippy's emotes didn't work on FICS because there, "i" is a
437 built-in alias for "it", not a real command. So sending "$i foo" gave
438 an error message instead of doing "it foo". We now leave out the
439 alias-suppressing prefix for emotes.
441 xboard/WinBoard 4.2.3 -- Mon Feb 19 19:55:05 PST 2001
444 * Bugfix: The error message "Variant X not supported by gnuchessx"
445 formerly could pop up even in -ncp mode.
447 * Fixed an xboard bug in premove highlighting. If you had
448 HighlightLastMove turned on, premoves got highlighted in
449 highlightSquareColor (yellow) instead of premoveHighlightColor (red).
451 * Modified premove again. Now we are back to displaying the move
452 locally immediately after sending it to the server, as in versions
453 prior to 4.2.1. This is good because it lets you register your next
454 premove sooner. As a better fix to the problem that the change in
455 4.2.1 had been trying to address, we now suppress animating the
456 opponent's move if you have a premove reply pending. However, it's
457 probably still a good idea for you to turn off AnimateMoves entirely
458 if you are trying to play extremely fast games.
460 * Removed an erroneous patch that left zombie chess engines around
461 when both sigterm and reuse were turned off. (Bug was in xboard only,
464 * Bugfix: loading a game with autostepping did not work for games with
465 PGN result "*" (unfinished). This bug was introduced in 4.1.0, caused
466 by some outdated code that was supposed to leave you in EditGame mode
467 after loading an unfinished game. I fixed this, and also changed it
468 to leave you in EditGame mode after loading *any* game, but without
469 changing the tags to say it's an edited game. It's not really clear
470 whether that is the best thing is to do here -- ideally, perhaps, the
471 tags should change to say "edited game" if you actually make any
472 changes, but that is harder to make work.
474 xboard/WinBoard 4.2.2 -- Tue Feb 6 20:00:00 PST 2001
477 * Fixed a problem introduced in 4.2.1. In -zippyPlay mode, 4.2.1
478 started sending the initString immediately after the old game ended,
479 but then when the next game started, it would still send "force" and
480 another initString. Another problem was that the first initString put
481 the engine out of sync with the displayed board position, though that
482 might not usually have been noticeable. This is now changed to do a
483 full Reset at the end of the previous game, and avoid doing a Reset at
484 the start of a new game if we are still in BeginningOfGame mode.
486 * Fixed some limitations in -zippyPlay mode. The engine was not being
487 fed the moves or history of games that were displayed but not being
488 played, so it would get confused if you tried to do something like
489 examine a game, then enter EditGame mode from somewhere in the middle
492 * Made a small change so that cygwin can compile xboard for Windows
493 (an X server is required to run it). Thanks to Volker Zell. Most
494 people would probably prefer to run WinBoard on Windows, however; note
495 that cygwin could already compile WinBoard.
497 * Added some missing documentation to engine-intf.html: It is okay to
498 send "feature done=0" even before you receive the xboard and protover
499 commands, if this is needed to give your engine enough time to
500 initialize. See engine-intf.html for more discussion.
502 * Bugfix: "feature done=0" did not work for the second engine; now it does.
504 xboard/WinBoard 4.2.1 -- Sat Feb 3 19:52:26 PST 2001
507 * Bugfix: in Zippy mode with feature san=1, the elapsed time was being
508 sent to the engine after the SAN move; for example, "e4 (0:01)" was
509 sent instead of just "e4".
511 * It seems that scroll wheel mice with incompletely installed software
512 (under Windows 95, at least) can send repeated middle button up events
513 when the wheel is turned. Moved QuickPaste from middle button up to
514 middle button down to avoid problems with this.
516 * A premove is now sent *before* the opponent's move that it replies
517 to is animated. The premove itself is no longer displayed (or
518 animated) when sent; instead, it is displayed when the chess server
519 echoes it back as a board update.
521 * Bug fix: in -xreuse mode, xboard was only sending command line
522 arguments to the engine the first time it was started. (WinBoard
523 didn't have this bug.)
525 * In -zippyPlay mode, we now initialize the chess engine for a new
526 game immediately after the old game ends. (In -xreuse mode, this
527 means starting a new engine process; in the default -reuse mode, it
528 just means sending "new".) If the engine supports ping, we don't
529 accept challenges until the "new" has finished. This should help
530 avoid losing time (re)initializing the engine after the game starts.
532 * We now handle the new FICS field in style 12 that says whether the
535 * whiteFlag and blackFlag are now reset whenever an ICS board image
536 arrives, giving autoflag a fresh chance to work.
538 * Suppressed "geometry error" debug messages unless -debug flag is given.
540 * Bugfix: avoid core dump on Solaris with -debug flag, caused by
541 passing NULL to a %s format in GameEnds.
543 * Added -firstProtocolVersion and -secondProtocolVersion. This will
544 allow use of extremely broken engines that hang or die when given the
545 "protover 2" command. It should be rarely if ever needed.
547 * Zippy now strips highlights from player names in the Creating
548 message; previously the ratings would not be extracted from this
549 message properly if you had set the highlight variable.
551 * Bug fix: Zippy with -zp but not -zt used to be fooled by false
552 partner tells inside channel tells; e.g.:
553 Garf(24): Garf (your partner) tells you: sit
555 * Bug fix: when an engine reported its name with the new "feature
556 myname=" command, we had been putting just that name into the window
557 title even when in TwoMachines mode.
559 * By default, WinBoard no longer uses the new feature introduced in
560 4.2.0beta of keeping the ICS menu, ICS server list, and lists of chess
561 engine command lines in separate files; instead, the lists are back in
562 the winboard.ini file. This gets rid of some problems where the
563 separate files could not be opened because the working directory was
564 not set to WinBoard's installation directory.
566 * WinBoard command lines and ini files now have another optional
567 syntax for quoting an option value. All characters within { } curly
568 braces are interpreted literally except for '}' itself. SaveSettings
569 now uses this syntax for string values that contain a backslash or
570 newline and do not contain a '}'. This should address the problem
571 that the separate .ini files had been meant to fix; engine command
572 line lists can now be written without \-escapes.
574 * Fixed three bugs in relaying moves between engines in TwoMachines
575 mode: an engine would be sent SAN if the *other* engine had set
576 feature san=1, a relayed SAN move did not end with a newline, and
577 feature usermove was not implemented for relayed moves.
579 * Fixed several bugs in exiting: File/Exit would sometimes hang;
580 timestamp/timeseal would not get killed off; an engine crash would
581 cause error messages to be printed recursively until stack overflow.
583 * Fixed a bug in the code to detect which ICS is in use and adapt to
584 it; the chess.net case was broken.
586 * Removed the leading alias-suppression character when sending a move
587 to ICS, because it seemed to break accuclock on chess.net.
589 * Fixed a bug where a FICS prompt like "10:01_fics%" would be matched
590 as finger note number 10, causing a problem detecting when the user is
593 * Added tellicsnoalias command to protocol.
595 * Changed st command in protocol back to old behavior.
597 * Added done=0 feature to protocol, to lengthen initial timeout.
599 * Added missing -colorSeek command line option to xboard. (Was
600 present in WinBoard.)
602 * Bug fix: setting feature reuse=0 was not working.
604 xboard/WinBoard 4.2.0beta -- Sat Dec 16 16:34:56 PST 2000
607 * Setting -searchTime no longer turns off -clockMode. Note that when
608 -searchTime is set, some engines may search for the lesser of
609 searchTime and the amount of time their normal clock management would
610 dictate, while others will disable their normal clock management and
611 always search for exactly searchTime.
613 * Fixed WinBoard bug where on Windows 2000 (and maybe Windows 98) the
614 ICS Interaction window would scroll back to the top whenever it filled
615 to capacity and WinBoard trimmed some text off the top.
617 * Changed xboard dragging so that the center of the dragged piece is
618 forced to be over the mouse cursor. (WinBoard dragging already worked
619 that way.) This should avoid confusing cases when you start a drag
620 with the mouse near the edge of a square -- formerly most or all of
621 the piece could be over one square but the mouse cursor over another.
624 * Added move list window for xboard. Code contributed by Manuel
625 Hoelss and re-hacked a bit by me. Performance of this window is poor,
626 because the implementation regenerates the entire window contents
627 whenever anything changes. It's hard to avoid this when using the
628 Athena List widget, though we could be a little smarter and notice
629 when the current move number has changed but the move list has not.
630 There are also several drawing problems caused by bugs in the Athena
631 Form and List widgets. The window should not really allow a
632 horizontal scroll bar, but the bugs are much worse if I turn it off.
633 In both Xaw and Xaw3d, the List widget tries to resize itself when
634 XawListChange is called, even if you tell it not to; and what's worse,
635 if the widget cannot resize itself to be large enough to avoid
636 clipping any of the list item, it does not change the list! Arrgh.
637 On top of that, the Xaw Form widget is very buggy in XFree86 4.0.1
640 * The OK button in the WinBoard startup dialog is now simply disabled
641 if none of the radio buttons is selected, instead of bringing up an
642 error dialog. Suggested by Ted Milbaugh.
644 * Used ping to address the worst of the race conditions in the
645 protocol. Now if an engine supports ping, we ping it after sending
646 the "new" command and after trying to place it in force mode at the
647 end of a game. When a ping has been sent and the corresponding pong
648 has not yet come back, we (1) ignore or undo any moves the engine
649 sends, (2) ignore game end messages (such as "offer draw", etc.) from
650 the engine, (3) ignore thinking output from the engine, (4) delay
651 starting the next game if in -matchGames mode, (5) in -zippyPlay mode,
652 respond to challenges with a polite message to try again soon instead
653 of accepting them. There are a few more things that should be done
654 (and item 5 might not be quite what we want), but it's hard to fit
655 them all into the existing code.
657 * Patched the version of GNU Chess 5.00 included with WinBoard to
658 support protover, feature, setboard, and ping, and to fix some minor
659 bugs. See gnu500+.patch.
661 * Changed the GNU Chess 4 kludges for missing "st" and "sd" commands
662 to be invoked only if the engine gives an error message for "st" or
663 "sd", and to always use protocol commands instead of engine
664 command-line options. See "Idioms" in engine-intf.html.
666 * Added new protocol command "protover 2" to tell the engine what
667 version of the protocol is in use. Version 2 is still compatible with
668 old engines; see engine-intf.html.
670 * Add new protocol command "feature ..." The engine can send this in
671 response to the protover command command, to say what extended
672 protocol features it would like to enable, etc. xboard responds
673 "accepted F" or "rejected F" for each feature F that is set. See
676 * Added new protocol command "setboard <fen>". This is an alternative
677 to "edit", used only if the engine says "feature setboard=1".
679 * Added new protocol command "ping <msg>". The engine is supposed to
680 respond "pong <msg>". This gives us a tool to fix some race
681 conditions in the protocol, but it is not used to the fullest yet.
683 * Added new protocol command "tellopponent". This will do a "say" if
684 you're on a chess server in Zippy mode, or pop up an information
687 * Added new protocol command "tellall". This will do a "kibitz" if
688 you're on a chess server in Zippy mode, or pop up an information
691 * Added new protocol command "tellothers". This will do a "whisper" if
692 you're on a chess server in Zippy mode, or do nothing otherwise.
694 * Changed the WinBoard /icsNames, /icsMenu, /firstChessProgramNames,
695 and /secondChessProgramNames options to accept a filename preceded by
696 "@", meaning to find the value in the file. Changed the defaults to
697 use this feature, with filenames icsnames.ini, icsmenu.ini, fcp.ini,
698 and scp.ini. This should make it easier for users to edit the values,
699 since one less level of quoting is needed, and each value is in its
700 own file, not mixed into winboard.ini. Those who upgrade from an
701 older winboard version and already have a winboard.ini file will not
702 automatically have these values moved to a file; that has to be done
705 * We now strip .exe from engine names for "name" command, tags, etc.
707 * Allowed WinBoard input widget to hold more than one line. You can get
708 a newline into the widget with copy/paste or with Ctrl+Enter.
710 * Fixed an xboard bug where the [P] button would appear in the
711 opposite highlight state from what it should be after being pressed.
713 * We now use the "/" or "$" alias suppression feature on the chess
714 servers, to avoid problems if the user inadvertently aliases a
715 needed command to something else.
717 * Changed the method used to deiconize xboard in AutoRaise and cmail.
718 This may fix bugs under some window managers where after
719 deiconization, the board window was mapped but nothing was drawn
722 * Preliminary, partial support for playing several chess variants
723 against a local engine or editing variant games. The -variant option
724 must be given on the command line or WinBoard startup dialog; there is
725 no menu. The current variant is not displayed (except in the
726 Tags/EditTags window). Many variants will not work quite right even
727 if the engine supports them; see item 326 in the ToDo file for
730 * Added a workaround to detect the variant type when examining a
731 scratch wild game on an ICS.
733 * Fixed two cases where "variant" command should be sent to the engine
734 when necessary but was not: loading a game from a file and restarting
735 a dead engine. Thanks to Gian-Carlo Pascutto.
737 * Added missing support for FICS games that start from a bsetup position
738 with Black moving first.
740 * Fixed a bug in loading a file from the game list window while in
741 Analysis or AnalyzeFile mode. This now leaves us in AnalyzeFile
742 mode, analyzing the new file.
744 * Fixed a bug in loading games with a comment before the first move.
746 * Fixed a bug in handling LoadGame (or -lgf) with -td 0.
748 * Added a command line option to select an initial minor mode from the
749 Mode menu. This should satisfy requests from a couple of users with
750 special applications.
752 * Fixed a problem where some things in WinBoard's General Options
753 dialog box were grayed out at the wrong time.
755 * We look for a few messages from the chess engine pipe that are
756 intended to catch problems starting an engine via rsh, such as "No
757 such file". Moved code so that these strings won't match until other
758 protocol messages have been looked for, and documented the messages in
761 * Fixed the WinBoard bug that sometimes made the console input box
762 white-on-white even when not in password-entry mode.
764 * Small changes to WinBoard to be compilable with the latest Cygwin
765 net release (as of 10-16-2000). Thanks to Mark Schoenberg.
767 * Recompiled GNU Chess 5.0 for WinBoard with the latest Cygwin net
768 release (as of 10-16-2000). Also rebuilt the book just to be sure,
769 since I had one bug report about it. It came out identical and seems
772 * Added messages for some common InstallShield errors instead of just
773 printing InstallShield's stupid error code numbers.
775 * Added -firstComputerString and -secondComputerString, allowing you
776 to suppress or change the command that is sent to a chess engine when
777 its opponent is another computer.
779 * Added "configure --with-Xaw3d" to allow use of Xaw3d widgets instead
780 of Xaw widgets in xboard. Thanks to Johnny C. Lam of the NetBSD
781 project. I've left Xaw as the default because Xaw3d is too ugly.
783 * The version of the Xaw Form widget released in XFree86 4.0.1
784 (X11R6.4.3) has a bug that causes xboard to display the button bar
785 on top of the message widget. I've reported the bug and have
786 installed a kludge workaround into xboard.
788 xboard/WinBoard 4.1.0 -- Sun Sep 17 17:30:14 PDT 2000
791 * Merged Winboard Plus 4.0.8 from Mark Williams into xboard
792 source pool. Status of Winboard Plus features in xboard:
794 - White pieces now have borders, but the implementation is
795 completely different from WinBoard's; see below.
797 - Options menu not changed, probably won't be.
799 - Copy&paste support working, using Mark's changes to backend.c, Ben
800 Nye's changes to xboard.c for FEN positions, and some code of my
801 own in xboard.c for PGN games.
803 - Premove hooked up and working. No pre-first-move, though.
805 - ICS Alarm hooked up and working.
809 - PGN Training mode hooked up and working.
811 - Improved menu item enable/disable working.
813 - Improved >> button working.
815 - Auto activate board working. I changed this to be optional; you
816 might not always want it, especially in Zippy mode.
820 - Documentation updated.
822 * Fixed more colorization bugs. Commands like "message foo tells you:
823 xxx" and "tell 33 tells you: xxx" will no longer generate bogus
826 * Added low-tech sound support to xboard, by invoking an external
827 program on a filename for each sound to be played.
829 * ICC wild 27 is now recognized as VariantAtomic, and it sets the
830 "ignore check" flag, but is not otherwise supported.
832 * Converted the piece bitmaps from .bm to .xpm for use with xboard's
833 xpm support. (An .xim version was not created.) Wrote a shell script
834 using ImageMagick to do the conversion and to bucket fill from
835 coordinate 0,0 with the background color. Used xpaint by hand to
836 clean up a few pieces where background color "leaked" into the inside
837 or didn't flow all the way around the outside, then a sed script to
838 fix up color names and bitmap names in the xpaint output. If any more
839 sizes are added later, they should be straightforward to convert with
840 reference to the existing scripts. With this conversion, not only do
841 the white pieces now have dark borders, but (unlike with WinBoard) the
842 light details on the black pieces are opaque.
844 * If the XPM library is found when building xboard, the new xpm pieces
845 are compiled in as the default. External bitmap (or xpm) pieces can
846 still be used by giving the -bitmapDirectory (or -xpmDirectory)
847 option. If the XPM library is not found, the old bitmap pieces are
848 the default. In this case external bitmap (or xim) pieces can be used
849 by giving the -bitmapDirectory (or -xpmDirectory) option. There is no
850 way to compile in xim pieces.
852 Winboard Plus 4.0.8 -- Sat Aug 5 15:51 PDT 2000
857 * Main menu now visible in Win NT. Thanks to Microsoft for creating a
858 compiler which auto-mutilates the WinBoard.rc file so that the menu is
859 displayed under Win 98 but not Win NT. I fixed the problem by hand editing the
862 * "Reset game" now works properly when invoked from Analysis mode when two
863 engines are present. Correction of bug introduced in Winboard Plus. Thanks to
864 Mogens Larsen for reporting the bug.
866 * Pasting a FEN position with Black to move now works in all modes.
867 Thanks to Mogens Larsen for reporting the bug.
869 * Added gnuchess.dat to the distribution and a couple of text files that were
872 *** Merged in the following changes from Tim Mann:
874 * Bugfix: Highlights would sometimes not be taken down, at least in
875 xboard. The problem is that SetHighlight works in chess coordinates,
876 not view coordinates, so if flipView has been toggled since the
877 highlight was put up, it gets taken down from the wrong square. Fixed
878 by being careful to call ClearHighlights before toggling flipView, not
881 * Bugfix: HighlightLastMove would sometimes highlight square a1 after
882 a FICS "tomove black" command.
884 * Bugfix: a move list with initial position that has black to play was
885 not being handled correctly.
887 * Removed "decline abort" and "decline adjourn" commands from Zippy.
888 The syntax is changing on FICS, and Zippy really doesn't have to
889 explicitly decline the requests anyway; it's sufficient to not accept
892 * ICC wild 26 is now recognized as VariantSuicide (the FICS name; ICC
893 calls it "giveaway").
895 * Bugfix: PGN games with black to move in the initial position weren't
896 being legality checked correctly. I think this was introduced in
897 4.0.6 when I fixed a different PGN bug. Thanks to Mark Williams for
898 spotting the bug and suggesting a fix.
900 * Bugfix: the initial "name(" of a kibitz wasn't being colorized.
902 Winboard Plus 4.0.7 -- Thu May 12 17:57 PDT 2000
905 * New white pieces with black borders.
907 * Major overhaul to Options menu. New dialogs for setting General Options,
908 Board Options, ICS Options, Sounds, Fonts, Colors.
910 * Clipboard support for PGN game scores and FEN positions.
912 * Optional ICS Premove with user-specified first moves for White and Black.
914 * New sound events: ICS Win, ICS Loss, ICS Draw, ICS Unfinished, ICS Alarm.
916 * New auto-flip option when playing against a chess program.
918 * Added PGN Training mode.
920 * Certain menu options now disabled while program is thinking.
922 * ">>" button now always goes to the end of the game.
924 * In ICS mode, the board is automatically activated at the start of a
927 4.0.7 -- Sun Mar 5 17:17:49 PST 2000 Tim Mann
929 * Fixed a nasty bug in parsing ICS game histories that was introduced
932 4.0.6 -- Fri Mar 3 16:20:11 PST 2000 Tim Mann
934 * Fixed bugs in Zippy's code for responding to messages sent with the
935 ICS "message" command.
937 * Fixed bugs where xboard could still create dialogs partially off the
938 top of the screen. Fixed unwanted interactions between initial sizes
939 and positions of various unrelated xboard dialogs. Deleted
940 borderXoffset and borderYoffset resources.
942 * Fixed restoring the xterm name on exit to work in more cases.
944 * Small fix to the WinBoard self-extracting installer: when it starts
945 up, it now always deletes any old wb-setup directory left over from a
946 previous installation. Formerly this worked only on Windows 95/98, so
947 on NT the self-extractor would sometimes stop and ask the user whether
948 it was OK to overwrite the old wb-setup files.
950 * Modified WinBoard to be compilable with the free Cygwin tools
951 available from http://sourceware.cygnus.com/cygwin/. Based on work by
952 Mark Schoenberg. (His mods were enough to get WinBoard through the
953 compiler, but a few things were broken along the way, so I reworked them.)
955 * Merged changes from Don Fong to make WinBoard compilable with
956 Borland C++ 4.5. I do not have Borland C++ and am unable to test with
957 it, but I did make sure the changes don't stop it working with MSVC++
960 * Forbade entering TwoMachines mode from MachineWhite or MachineBlack
961 mode when machine is on move. This used to confuse the engine and
962 cause problems, because when we try to get the engine to stop, it
963 might make a move first, and it might not do that immediately.
965 * Variant classification now deals with new ICC wild 25, classifying
966 it as "3check". Also, we are now conservative about new wild numbers
967 we don't know about, classifying them as "unknown" instead of
970 * Replaced bad GNU Chess 5.00 book in WinBoard distribution with a
971 correct one. 1.e4 now no longer takes GNU Chess 5.00 out of book!
972 Thanks to Pete Galati.
974 * Made move parser accept and ignore nonstandard ep suffix on PGN moves,
975 e.g., "exf6ep" or "exf6e.p."
977 * Fixed bugs in parsing PGN files starting with no move number, or
978 with a move number other than "1." (including "1..."). Thanks to
979 Michael Soulier and Stefan Zipproth for example PGN files
980 demonstrating the bugs.
982 * Changed InitComboStringsFromString to not modify the input string;
983 this caused an exception when WinBoard was compiled with MSVC++ 6.
984 Thanks to Bert Tuyt for the report.
986 * In WinBoard, dragging a piece off the edge of the board without
987 releasing the mouse button no longer instantly aborts the move. You
988 still must release the mouse button inside a square to complete a
989 move, but you can now drag off the edge and come back inside.
991 * WinBoard bugfix: If you went into EditGame or EditPosition mode
992 while observing or playing an ICS game, and a new move came in
993 (snapping you back to ICSClient mode) while you were dragging a piece
994 around, the drag state would not be reset, causing the piece you were
995 dragging to remain on the board wherever you dropped it. Thanks to
996 David Brinegar for the bug report.
998 * WinBoard bugfix: If you moved or resized the board while your
999 opponent was moving, and you had AnimateMoving on, his move would not
1000 be displayed until after your next move. Thanks to DAV for reporting
1001 the bug repeatedly until I finally understood it.
1003 * Added a Zippy "farewell" feature; see zippy.README.
1005 * Fixed a bug (xboard only) in processing -zippyReplayTimeout on the
1006 command line. Thanks to Steve Beer for the report and patch.
1008 * Send "computer" command to both sides in TwoMachines matches.
1010 * Fixed a Y2K bug in Evan's cmail code! Thanks to Brian Mays for the
1013 * Bugfix: Initialize variant field of GameInfo struct in gameinfo.c.
1014 This could cause crashes in LoadGame. Thanks to Andrzej Nagorko.
1016 * Fixed several pattern matching problems: Finger notes and formula
1017 vars no longer get replied to by zippyTalk or colorized. Channel
1018 tells by players with many titles are now colorized fully, and
1019 zippyTalk handles channel tells by such players correctly. The shout
1020 "--> foo(99): bar" no longer gets colorized as a channel tell. Code
1021 is cleaned up a bit, and autocomment capture now uses the same
1022 criteria as colorization.
1024 * xboard fix: Enter key now closes error popups as in WinBoard.
1025 Especially nice for the "Exiting: Connection closed by ICS" popup.
1027 4.0.5 -- Tue Dec 7 10:30:40 PST 1999 Tim Mann
1029 * Added missing documentation of SIGTERM usage into engine-intf.html.
1031 * Bugfix: New -zippyReplayTimeout option was misspelled in WinBoard as
1032 -zippyReplyTimeout. Thanks to Francesco Di Tolla.
1034 * xboard -ics now restores the xterm's original title upon exit, at
1035 least if $WINDOWID is set.
1037 * Bugfix: -matchGames mode wasn't terminating properly. Final score
1038 popup would come up twice and engines would not be killed off. Thanks
1039 to Frank Quisinsky for the bug report. Bug was introduced in 4.0.4.
1041 * Bugfix: "tell 50 foo shouts: bar" no longer gets colored as a shout;
1042 similarly for "...s-shouts:" and "...c-shouts:". Thanks to David Lee
1045 4.0.4 -- Fri Dec 3 17:51:27 PST 1999 Tim Mann
1047 * Bug fix: formerly if you invoked SaveGame from EditPosition mode
1048 with black to play, the position was not saved properly. As a quick
1049 fix, SaveGame now takes you out of EditPosition mode before saving.
1051 * Changed -matchGames to keep track of the score (won-lost-drawn) and
1052 display it in the banner. The final score is displayed in a modal
1053 popup before the program exits.
1055 * Changed "Connection closed by ICS" to display in a model popup
1056 before the program exits.
1058 * Added -popupExitMessage option, default on. Setting this to false
1059 suppresses the modal popups that you sometimes get just before
1060 xboard/winboard exits -- both the two new ones listed above and the
1061 existing Fatal Error popup. This is useful when running Zippy
1062 unattended from a shell script (or .bat file) that loops and starts a
1063 new copy after a time delay when there is an error.
1065 * In xboard, added missing support for WM_DELETE_WINDOW to all
1066 windows. This makes xboard a better citizen, and is much needed with
1067 the newer X window managers that put an [X] button on every window and
1068 bind it to "kill application" if the applicationd does not support
1069 "delete window". We can't allow xboard to be thoughtlessly killed,
1070 since that leaves the chess engine running in the background.
1072 * We now avoid positioning tops of xboard dialog boxes offscreen.
1074 * zippy.lines can now use the caret ('^') character as an inter-saying
1075 separator. You no longer need to dig up a text editor that can put NUL
1076 ('\000') characters in text files.
1078 * Bugfix: In traditional chess clock mode, White now gets time added
1079 to its clock as soon as it makes time control. Previously both White
1080 and Black got their time added only when Black made time control,
1081 which would cause some engines to make their 41st move as White too
1082 quickly, thinking they were low on time.
1084 * The zippyAcceptOnly feature no longer sends a decline command or
1085 a tell. Thus you can use it to put Zippy into a manual accept mode.
1087 * Bugfix: "tell 50 foo tells you: bar" no longer gets colored as a
1088 personal tell; similarly for "...whispers:" and "...kibitzes:".
1090 * WinBoard no longer blanks the message line when you start a new
1091 move, unless there was an error message there from the previous move.
1093 * WinBoard now never puts the white piece drop menu on the middle
1094 mouse button. Both colors are always on the right button. Windows
1095 users often don't think to look for a middle button menu, or don't
1096 really have a working middle button despite what Windows says.
1098 * Guest login handles on ICC are now parsed again; an ICC wording
1099 change had broken this feature.
1101 * Autodetect when the engine does not support the "draw" command and
1102 don't relay the command to it in that case. Needed because sending an
1103 unsupported command to GNU Chess makes it move immediately, so people
1104 could make Zippy move without thinking by continually offering a draw.
1105 Thanks to Frank Walker for the problem report.
1107 * Small changes based on code from Robert Jurjevic: The WinBoard
1108 analysis window can be minimized (though not to the taskbar). The
1109 WinBoard ICS Interaction window will autoscroll if you drag the mouse
1110 above or below the window while selecting, and password entry mode
1111 leaves the entry line as the background color instead of using 75%
1112 gray. Seeks are now colorized with a new color of their own.
1114 * Added -zippyMaxGames feature.
1116 * -zippyNoplayCrafty command line option was missing in xboard; fixed.
1117 Thanks to John Perry.
1119 * Fixed bug in detecting when Zippy loses his bughouse partner.
1120 Thanks to Ben Dean-Kawamura.
1122 * allobs fix in 4.0.3 didn't work; corrected it.
1124 * WinBoard will now update the board immediately if a move is made
1125 while the window is being moved or resized.
1127 4.0.3 -- Sun Aug 15 18:44:39 PDT 1999 Tim Mann
1129 * Bugfix: moved winboard wizard functions that send a command directly
1130 to the chess engine from Ctrl+Alt+1 and Ctrl+Alt+2 to Alt+1 and Alt+2.
1131 Ctrl+Alt is equivalent to the European AltGr key, so the old assignments
1132 conflicted with typing an @-sign on some keyboards.
1134 * Bugfix: prevent "If this message stays up, your chess program does
1135 not support analysis" from appearing if AnalysisMode is selected when
1136 already in Analysis or AnalyzeFile mode. Also, deleting analysis window
1137 in WinBoard now switches you to EditGame mode, to avoid the anomaly of
1138 being in an analysis mode with no analysis window present.
1140 * Change all Zippy environment variables to work as command line
1141 options. For now they still work as environment variables too, but
1142 the environment variables are deprecated.
1144 * Use unsigned long to hold node counts from engines.
1146 * Print error instead of crashing on attempts to use xpm or xim pieces
1147 in monochrome mode. Thanks to Jim Torrance for the bug report.
1149 * Tightened pattern recognition for ICS messages sent to Zippy; should
1150 no longer match ICC allobs output. Fixed recognition of when Zippy is
1151 sent a message; small change to FICS output had broken it.
1153 * Zippy now exits if the engine dies unexpectedly.
1155 * Added Zippy "spoofedby" feature; see zippy.README.
1157 * Narrowed the margins on some older WinBoard dialogs to make their
1158 style uniform with the newer ones.
1160 * Bugfix: Changing Ponder Next Move from the Options menu did not take
1161 effect until the next game. This bug was in WinBoard only. Thanks to
1162 Stefan Zipproth for the bug report.
1164 * Got rid of "Internal error: bad move type" message when the engine
1165 makes a move that we can parse but think is illegal. Now the move is
1166 just passed on (which also may be the wrong thing to do).
1168 4.0.2 -- Thu Feb 25 19:55:32 PST 1999 Tim Mann
1170 * Added one more built-in sound choice to WinBoard: move.wav from Pete
1173 * Added new larger piece sizes: big, huge, giant, colossal, titanic.
1175 * Modified the xboard font searcher to be able to use scalable fonts.
1176 The new -fontSizeTolerance flag controls how closely a nonscalable
1177 font must match to be used in preference to a scalable font.
1179 * Zippy environment variables ZIPPYABORT and ZIPPYADJOURN now control
1180 whether Zippy will accept abort and adjourn requests.
1182 * We now determine the variant type being played on ICS, send it as a
1183 command "variant VARTYPE" to the chess engine (if in Zippy mode), and
1184 put it in the PGN tags. See engine-intf.txt for variant names. See
1185 ZIPPYVARIANTS in zippy.README to control what variants Zippy will
1186 accept. Note that this now applies to bughouse, too.
1188 * Zippy now won't do -zippyTalk in a channel unless his handle is
1191 * Zippy now ignores bughouse holdings if not actually playing, instead
1192 of stupidly trying to abort the game. Let me know if other strange
1193 things happen when Zippy is observing a game.
1195 * Set ICS Interaction title bar to "user@server". User name is
1196 determined by parsing message during the login sequence. Zippy now
1197 uses this method to get its name too, so ZIPPYNAME is eliminated.
1198 Problem: with xboard, the title bar gets set to "xterm" upon exit,
1199 since we didn't know what it was to start with.
1201 * Fixed xboard-only bug in -colorChannel1 command line option. Thanks
1202 to Fredrik Sandstrom for the bug report and fix.
1204 * Check for overflow of MAX_MOVES. Still not sure this is checked for
1205 everywhere it needs to be.
1207 * Added .epd to suffixes recognized by WinBoard as position files.
1208 This is a bit of a kludge, as the .fen reading code was not written
1209 with .epd files in mind, but reading them with it is said to work.
1211 * Added ZIPPYGAMESTART feature, suggested by Jason Hoblit. See
1214 * Restored the feature of soaking up the moves from a user-typed "moves",
1215 "oldmoves", or "smoves" ICS command when xboard/WinBoard is idle, but
1216 changed it so that the move list is also echoed to the screen. Some folks
1217 still liked the old feature since it is faster than examine mode, and
1218 printing the moves to the screen should eliminate the confusion it caused
1221 * Bugfix: in WinBoard, starting a click-click move and then clicking on
1222 a black line would cause the source square to be forgotten without taking
1223 the highlight down. Now the errant click is ignored.
1225 * Corrected shortcut key labels for LoadNext/PrevPosition in WinBoard's
1226 File menu. Thanks to Andreas Stabel for the bug report.
1228 * Bugfix: if you had a completely full ICS context menu in WinBoard
1229 (90 items), the last one would do nothing if selected.
1231 * The "computer" engine command added in 4.0.1 was not working; I had
1232 left out part of the code patch. Oops.
1234 4.0.1 -- Fri Feb 12 21:24:15 PST 1999 Tim Mann
1236 This is a minor bugfix release. The first item listed below is the
1237 only interesting new feature.
1239 * You can now type in moves from the keyboard in WinBoard. Either
1240 select TypeInMove from Step menu, or (if you are not in ICS mode),
1241 just start typing. In ICS mode you can type moves into the ICS
1242 interaction window anyway, so I've retained the feature that typing
1243 switches you there. Not implemented in xboard.
1245 * Removed the "noise 1000" command that used to be sent to the chess
1246 engine when entering analysis modes.
1248 * Deleted the feature where we soak up the output of a user-typed ICS
1249 "moves" or "oldmoves" command. This ancient feature is not really
1250 useful anymore, now that "examine" exists, and it caused a lot of
1253 * Increased maximum size of ICS text menu to 90 entries and added
1256 * The command sent to ICS by Zippy at the end of each game can now be
1257 customized with the ZIPPYGAMEEND environment variable.
1259 * We treat xboard.info as a pseudo-source since most people don't have
1260 the tools to rebuild it. But "make install" erroneously had a
1261 dependency on it, even though "make all" did not. Fixed.
1263 * Miscellaneous minor updates and clarifications to engine-intf.txt.
1264 In particular, documented the st and sd commands (support for command
1265 line options -searchTime and -searchDepth), warts and all.
1267 * Added a small code patch from Bob Hyatt to detect when Zippy's ICS
1268 opponent is a computer and send the command "computer" to the engine.
1269 Added this command to engine-intf.txt. Thanks, Bob.
1271 * Bugfix: configure was looking for usleep(), but config.h.in didn't
1272 have an entry for it, so HAVE_USLEEP was never defined. Also, in the
1273 non-HAVE_USLEEP case, there was a possible race condition between the
1274 signal handler and the pause() call. Thanks to Ben Dean-Kawamura for
1277 * Bugfix: a "1..." preceding Black's first move (usually present if
1278 there is a comment on White's first move) would cause the parser
1279 to think a new game started there and report "End of game" on the
1280 current game. Thanks to Dell Garner for the bug report.
1282 * Changed the abbreviation for -searchDepth from -sd to -depth to fix
1283 a clash with -secondDirectory.
1285 * Changed -searchDepth to be orthogonal to the various timing options.
1286 Previously it would search for an unlimited time to the given depth;
1287 now the engine is allowed to choose its search time in the normal way,
1288 but is told to cut off the search early if it reaches the given depth.
1290 * Bugfix: SaveSettings in WinBoard was saving both the long form
1291 option highlightSquareColor and its abbreviation (hsc).
1293 * Fixed a redisplay bug in DisplayBothClocks that could cause White's
1294 clock to be highlighted in EditPosition mode when Black's should have been.
1296 * Fixed Zippy's feature of passing on draw offers from the ICS opponent.
1297 The colorization code was eating the offer before Zippy saw it, so I disabled
1298 colorization of offers while in -zp or -zt mode. (Other types of
1299 colorization are already disabled in Zippy mode for similar reasons.)
1301 * Added some more commands to the default ICS context menu in WinBoard,
1302 and put "(name)" on the ones that insert a playername (or game number).
1304 * Added missing documentation to WinBoard help file: PonderNextMove, the
1305 -ponder/-xponder argument, and the up/down arrow history feature in the
1306 ICS Interaction window.
1308 * Fixed ZIPPYNOPLAYCRAFTY feature to fire only if the opponent is Crafty,
1309 not if some other Crafty is observing the game and kibitzes.
1311 * Fixed bugs in generating "partner" commands when Zippy is playing
1314 4.0.0 -- Sat Jun 20 16:59:47 PDT 1998 Tim Mann
1316 * Fixed WinBoard resizing so that the edges you do not drag remain in
1317 place, even when the final size is different from what you dragged to.
1318 (This doesn't work on NT 3.51 or earlier, if anyone cares.)
1320 * Fixed problems with resizing WinBoard on Windows NT: you no longer get
1321 whitespace around the board, a clipped board, or a lot of flashing during
1324 * Added customization for highlight-square color.
1326 * Bugfix: backend.c wrote to stderr in a few obscure places, which doesn't
1329 * Added Index Number field back to LoadGame/LoadPosition dialog boxes in
1330 WinBoard. This required some extra code to work with both the
1331 Explorer-style dialog boxes and the old-style NT 3.51 dialog boxes. Ugh.
1333 * WinBoard startup dialog now understands -zp mode. The first chess
1334 engine selector is enabled and the value is used.
1336 * Bugfix: ResetGame would send "exit" to engine twice if it was in an
1339 * Bugfix: The response "Illegal move: bk" to the "bk" command, indicating
1340 that it is not implemented, would confuse xboard.
1342 * Bugfix: Ignore empty hints ("Hint:\n") instead of printing a message
1343 saying that some bogus string (often "Hint:") is illegal.
1345 * Bugfix: LoadNextGame/LoadPreviousGame/ReloadSameGame were broken.
1347 3.6.12 -- Sat Jun 13 14:57:10 PDT 1998 Tim Mann
1349 Beta test release of xboard and WinBoard.
1351 * Spruced up xboard man page a bit.
1353 * Added Highlight Last Move to xboard too.
1355 * The revamped xboard mouse click code had several more bugs than the
1356 previous version, so I revamped it again. All fixed now, I hope.
1358 * xboard bugfix: crash in CreatePieceMenu.
1360 * Oops. winboard-3_6_11beta.exe installed 3.6.10beta, not the new version.
1362 3.6.11 -- Fri Jun 12 20:00:48 PDT 1998 Tim Mann
1364 Beta test release of xboard and WinBoard.
1366 * Major reorganization to engine-intf.txt. Some new features added,
1367 many existing features clarified and hints for engine programmers added.
1368 Support for new features added to program.
1370 * Changed defaults for -scp (etc.) back to being independent of -fcp, as
1371 in 3.6.2. That is, the default is no longer to copy the value from -fcp if
1372 -scp is not specified. This will sometimes make command lines longer but
1373 will remove some confusing situations.
1375 * Split -reuseChessPrograms into two options: -reuseFirst and
1376 -reuseSecond. Fixed obscure bugs when reuse is off.
1378 * Detect ICC and change some command usage slightly there: only ICC has
1379 set-quietly; only FICS has iset and bsetup clear. With this feature, we
1380 can now safely use bsetup clear when appropriate instead of deleting each
1383 * Added indent to lines that are wrapped by WinBoard ICS Interaction
1384 window. This seems to tickle a Microsoft bug in the RichEdit control:
1385 occasionally the start of the next line after the wrapped line is indented
1386 too. I think the wrapped indent feature is useful enough that it's worth
1387 having in spite of the bug.
1389 * WinBoard bugfix: bounding box for the board was computed incorrectly by
1390 mouse code. It would think you moved off the bottom of the board before
1391 you really did, so it was hard to drag pieces along the bottom rank on
1392 smaller board sizes.
1394 * Fixed obscure parser.l bug: ambiguity between capture using : instead of
1395 x and email header line. Also removed or simplified a lot of complex
1396 patterns for English (as opposed to PGN) end-of-game indications while I
1399 * Added PonderNextMove option.
1401 * xboard EditPosition piece menus now let you set the side to play by
1402 selecting the "White" or "Black" label at the top of the menu, like
1403 WinBoard. (Both xboard and WinBoard still let you set the side to play by
1404 clicking on the clock.)
1406 * Merged documentation of Crafty and GNU Chess thinking output in
1407 engine-intf.txt. Corrected code in backend.c to match documentation; it
1408 used to require the PV to start in column 27 (!).
1410 * Fixed bug that caused crashes in "-reuseChessProgram false" mode.
1412 * Draw by agreement in Two Machines mode now works as it is supposed to.
1413 Other minor bugs in handling game end messages from machines are also
1414 fixed, and engine-intf.txt is revised in this area.
1416 * Revamped xboard code for handling mouse clicks on the board. In
1417 particular, it had a bug if a click-click promotion move was made.
1419 * Fixed and reinstated optimization for << in analysis modes: send
1420 initString and re-send the board if needed. Sending repeated undos
1421 is bad because Crafty prints some analysis after every one.
1423 * Don't go into a spin loop while pausing between xboard animation frames.
1424 This caused problems, especially when compiling with -O2 on HP-UX.
1426 * WinBoard Options/Colors/RevertToDefaults now also turns off Monochrome
1427 if it was on, and similarly for Options/ICSInteractionColors/RevertToDefaults.
1428 This seemed to confuse people before.
1430 * Bugfix: ICS Interaction context menu items with neither of the two
1431 optional flags set did not work.
1433 * Bugfix: PGN move numbers are optional, but we were insisting on "1"
1434 right after the tags.
1436 * Bugfix: only the first game of an -mg match was loading -lpf or -lgf.
1438 * Other minor fixes and code cleanup.
1440 3.6.10 -- Mon Jun 1 01:32:31 PDT 1998 Tim Mann
1442 * Added ZIPPYNOPLAYCRAFTY feature; see zippy.README.
1444 * Added timestamps for chess engine interaction to -debug output.
1446 * Now allow 10 seconds (was 5) between games in match mode for engines to
1447 respond to "force" command that ended previous game.
1449 * When a game is picked from the game list and the names of White and
1450 Black are known, display them in the window banner instead of the filename
1453 * Changed default for -scp and -sd to be the values of -fcp and -fd.
1455 * Added boxes for both engines to WinBoard startup dialog. Changed to
1456 dropdown boxes whose content can be set from winboard.ini, similar to
1457 the box for ICS name.
1459 * Accept "offer draw" (or "*offer*draw*") from engine to offer a draw.
1461 * Accept "move mmmm" from engine as well as silly "1. ... mmmm" syntax.
1463 * Added support for bughouse engines (Zippy mode only).
1465 * Move bombproofing for engines sending illegal or out of turn moves.
1467 * Always send "xboard\n" to engine as first command. Eliminates need
1468 to run crafty as "crafty xboard".
1470 * Rewrote xboard code for input from engines to fix longstanding bugs.
1471 Previously an engine that sent one line in two separate writes with
1472 some time lapse in between (or perhaps that sent several lines in one
1473 write) could make xboard hang. WinBoard did not have this bug.
1475 * Fixed minor bugs in dealing with illegal moves.
1477 * Added "iset startpos 1" for FICS.
1479 * Removed special support to put "GNU Chess" or "Crafty" in the window
1480 banner instead of the engine's base filename. This gives a more level
1481 playing field for other engines. Also fixed bugs in the code that finds the
1482 engine's base filename.
1484 * Bugfix: Abort or Resign at the very start of a game in chess engine mode
1485 would fail to send "force" to the engine.
1487 * Fixed some minor bugs in new "result" messages, and changed format to
1488 include a trailing PGN comment giving the reason the game ended.
1490 * Changed syntax of /font options in WinBoard; old syntax was assuming
1491 that a font name can't contain a digit, which is wrong. Old font names in
1492 WinBoard.ini files are still accepted.
1494 * Serious further work on getting WinBoard to read/write files in the
1495 "right" directories and documenting exactly what it does.
1497 * Added LoadPreviousPosition, LoadNextPosition, ReloadSamePosition.
1499 * Misc. tiny fixes and cleanup.
1501 3.6.9 -- Sun May 24 20:53:08 PDT 1998 Tim Mann
1503 xboard and WinBoard beta release.
1505 * Tightened up illegal move handling. Illegal or meaningless moves from a
1506 file or chess engine should no longer get translated into a1a1 and blindly
1507 applied. Explicit moves to the same square (like a1a1) no longer make the
1508 piece on that square capture itself and vanish.
1510 * Added AlwaysOnTop feature to winboard.
1512 * Fixed bug in winboard "@" command line indirection operator.
1514 * Removed buggy "optimization" code for ToStart in analysis modes.
1516 * Fixed typo bug in zippy.c that would often cause winboard to crash
1517 right after starting a game in -zp mode.
1519 3.6.8 -- Sat May 23 22:23:19 PDT 1998 Tim Mann
1521 xboard and WinBoard beta release.
1523 * Added -firstDirectory and -secondDirectory so that chess engines can
1524 be started in a different directory from xboard/WinBoard itself.
1526 * Added -matchGames to allow more than one game in -matchMode. The games
1527 are played with colors alternating between the two chess engines. Had to
1528 add a time delay at the end of each game to catch up with game ending
1529 messages from both chess engines -- yuck.
1531 * Changed TwoMachines mode to have firstChessProgram play White by
1532 default. Added -firstPlaysBlack to restore old behavior.
1534 * Major rework of code in backend.c for dealing with first and second
1535 chess engines. Generalized the code and created a struct type with one
1536 instance for each engine. Several small bugs fixed along the way.
1538 * Fixed bugs in Abort in local chess engine mode.
1540 * Tightened pattern matching to recognize moves from machine. Should cure
1541 bogus "Illegal move" errors while Crafty is pondering with Show Thinking
1542 on, among other things.
1544 * WinBoard keeps focus in board window after popping up a comment due to
1545 Forward/Backward/ToStart/ToEnd commands.
1547 * Finally got rid of warnings on compiling moves.c under Windows.
1549 * Fixed so WinBoard will compile on machines where WM_MOUSELEAVE is not
1552 * Removed various bits of unused code.
1554 * Parse (and ignore) NAGs in PGN files.
1556 * Updated engine-intf.txt.
1558 * Send "result R" to the chess program at the end of each game, where
1559 R is the PGN result 1-0, 0-1, 1/2-1/2, or *.
1561 * Bugfix: suppress animation when loading a game with timeDelay=0.
1563 * Bug fix: pondering output from Crafty that contained "..." could be
1564 mistaken for a move, causing bogus error messages and general chaos.
1566 * xboard "make clean" bug fix: moved things created by configure to be
1567 removed only by "make distclean".
1569 * Fixed a remaining case where move was being animated before being
1570 relayed to opponent.
1572 * Backend was reversing time/otim commands to the chess program (new bug),
1573 and was often not sending them on the first move of a game or the first
1574 move after a mode change (old bug). Fixing the latter required a kludge
1575 to work with both GNU Chess and Crafty, because Crafty swaps white and
1576 black clock times when it swaps sides, while GNU Chess does not. The
1577 kludge is that we always make sure the chess engine thinks its opponent is
1578 on move before we set the clock. This will sometimes result in sequences
1579 like "white\ntime xxx\notim yyy\nblack\ngo", or the same with white and
1582 * Removed last trace of old -whiteString and -blackString arguments.
1584 * Fixed so that you can type "bd" into the Direct Command dialog when
1585 debugging gnuchess, without having xboard parse the clock display
1586 (starting with "White") as "White wins" and end the game.
1588 * Changed moves.c to make a distinction between IllegalMove (where we
1589 could tell what move was intended, but it violates the chess rules) and
1590 MeaninglessMove (where we could not tell). This is a step towards getting
1591 rid of cases where we translate meaningless moves into "a1a1", but some
1592 work is probably needed to track them all down.
1594 * Fixed bug in WinBoard monoMode dragging.
1596 * Changed WinBoard to new style file dialogs. In the process, disabled
1597 the feature that let you enter the index number of a game or position within
1598 the file in the dialog. This is no loss in LoadGame, as you can pick your
1599 game from the game list dialog that follows, but it does remove some
1600 functionality from LoadPosition.
1602 3.6.7 -- Mon May 18 21:25:00 PDT 1998 Tim Mann
1604 xboard and WinBoard beta test release. I've been unable to reproduce some
1605 reported drawing bugs, so they may still not be fixed.
1607 * Changed PopUpErrors option to PopupMoveErrors, which is more useful, and
1608 changed default to off. Errors other than move errors should always be in
1609 popups; they are often too big for the message area and too important to
1610 put where they can be easily missed. But it seems good to get rid of the
1611 popups for move errors by default.
1613 * xboard analysis window no longer forces itself to top whenever there is
1614 new output. Also, now uses built-in Xaw word wrapping instead of trying
1615 to do its own; works better.
1617 * Bugfix: Reset did not take Crafty out of analyze mode.
1619 * A chess engine no longer has to claim to be Crafty to be able to use
1620 AnalysisMode and AnalyzeFile; it just has to implement the analyze
1621 command as Crafty does. Put in heuristics to generate more informative
1622 error messages if the engine does not support analyze, and checked that
1623 they work at least with GNU Chess.
1625 * Added click-click moving, HighlightLastMove, and HighlightDragging to
1626 WinBoard. The highlight features are unlikely to go into xboard unless
1627 the xboard drawing code is cleaned up to do *all* drawing on the board
1628 from DrawPosition, as WinBoard does. This is low priority for me.
1630 * Eliminated bogus "Error gathering move list: no header" popup. You
1631 could get this by observing two fast games at once without turning off
1634 * Disable WinBoard Sounds menu entirely in -ncp mode, since not even
1635 MoveSound is used in that mode.
1637 * WinBoard bugfix: Several problems were caused if the user changed
1638 WinBoard's current directory in a Load, Save, or Browse dialog. In
1639 particular, WinBoard.ini would get saved in the wrong directory, and
1640 sound .wav file names would not get saved with a full pathname. I think
1641 all such problems are now fixed.
1643 * WinBoard bugfix: iconizing the board after an aborted mouse resize would
1644 (partially) resize it to Tiny.
1646 * WinBoard bugfix: board was not being drawn in color on 256-color
1647 displays. This bug was introduced in 3.6.6.
1649 3.6.6 -- Tue May 12 17:43:43 PDT 1998 Tim Mann
1651 xboard and WinBoard beta release. Note: not all reported bugs are fixed.
1653 * Move animation in WinBoard, programmed by Henrik Gram. Great stuff!
1655 * Animate backward moves too.
1657 * xboard bugfix: -font (and friends) can now specify a font alias (such
1658 as "fixed"), not just a full X Consortium name pattern. Previously this
1659 would give a resource conversion error message.
1661 * Some coding style cleanup in xboard.c.
1663 * Earlier error check for moving wrong color piece in EditGame mode.
1665 * Completed fix to pattern matching; see 3.6.5.
1667 * Fixed some software rot bugs in Zippy.
1669 * Split AnimateDragging as separate option from AnimateMoves.
1671 * Added FlashMoves to options menu and -flash/-xflash to command line
1672 options (xboard only).
1674 * Some preliminary work on visible bughouse holding support. Most of the
1675 code is not present in this release because I have not gotten it working
1676 properly yet; my first approach went down a blind alley and I had to
1677 remove most of the partially working code in preparation for a rewrite.
1679 3.6.5 -- Fri May 8 14:22:09 PDT 1998 Tim Mann
1681 Not generally released.
1683 * Pack bughouse holdings display in banner more tightly when board is one
1684 of the smaller sizes (when smallLayout or tinyLayout is true, that is).
1685 An interim measure, but should help.
1687 * Completed fix to make move list parsing recognize the end condition and
1690 * Fixed pattern matching for chatter (tells, etc.) to be more reliable.
1691 This should reduce the incidence of colors starting in the wrong place and
1692 of incorrectly matching things that look like other patterns inside
1693 chatter, such as "shout <12>". (These errors were already rare.)
1695 * WinBoard now lets you customize the list of ICS's in the startup dialog.
1696 For now, at least, requires editing WinBoard.ini with a text editor.
1698 * Bug fix: WinBoard window sizing and position setting save/restore did
1699 not work right when the taskbar was at the top (or left side) of the
1700 screen and not in autohide mode.
1702 * Merged xboard click/click mode and drag mode, and deleted
1703 ClickClickMoving option on menu. Now if you click on a piece, it
1704 highlights and a further click on another square will move it. (A second
1705 click on the same square takes down the highlight.) Or if you press down
1706 on a piece and start to drag, you can drag it to a new square.
1708 * When making click/click style moves, if your second click is on a piece
1709 of the same color, instead of saying "Illegal move", we now cancel the first
1710 starting square, replace it with the second, and wait for another click to
1713 * Separate -secondInitString. Default: same as -initString. Suggested by
1716 * Patch from Frank McIngvale to make animation work with XIMs. Yay!
1718 * Changed move animation to happen after move is passed on to ICS or the
1719 chess engine, where applicable. Fixed problems with updating moveList
1720 that this uncovered.
1722 * Changed game list to show PGN result token for each game.
1724 * The usual minor bug fixes.
1726 3.6.4 -- Thu Apr 30 23:14:43 PDT 1998 Tim Mann
1728 xboard and WinBoard beta test release.
1730 * xboard documentation updated, both man page and info file. An attempt
1731 to generate both from the same source with LinuxDocSGML was abandoned, at
1732 least for now. WinBoard doc updated too.
1734 * Merged updates to animation code from Hugh. Fixed a couple of remaining
1735 bugs, mostly to do with handling Pause mode correctly.
1737 * Added SaveSettingsOnExit to WinBoard.
1739 * WinBoard now saves the last screen position of the Comment, Edit Tags,
1740 Game List, and Analysis windows (in addition to the board and ICS
1741 Interaction windows) in WinBoard.ini.
1743 * WinBoard now provides a way to customize the right-button context menu
1744 in the output area of the ICS Interaction window. For now, requires
1745 editing WinBoard.ini with a text editor.
1747 * Various minor fixes to ICS message recognition, most affecting only Zippy.
1749 * Colorize the notification when someone sends you a message while you are
1750 logged in, not the output of the "messages" command.
1752 * Fixed colorization to turn off at the right place more reliably.
1754 * Added a new color and WinBoard sound for "requests": abort, adjourn,
1755 draw, pause, and takeback. The same color and sound are used for all of
1758 * Added GUI to change sounds in WinBoard.
1760 * Suppressed WinBoard error popup when a sound can't be played. They were
1761 popping up when two separate WinBoards tried to play a sound at the same
1762 time (such as during a bughouse match).
1764 * Fixed WinBoard crash when a sound file didn't exist.
1766 * WinBoard ports of timestamp and timeseal now produce decent error
1767 messages if they fail to connect, and WinBoard captures the messages and
1768 puts them into a popup. Previously WinBoard would exit with no message on
1771 * WinBoard resizing with mouse improved; now accurately picks the largest
1772 size that fits in the new area.
1774 * Added option to turn off error message popups.
1776 * Added sizes slim, dinky, and teeny.
1778 * Fixed some minor problems with error message wording.
1780 3.6.3 -- Mon Feb 23 19:08:57 PST 1998 Tim Mann
1782 xboard beta test release only. Man page is updated for the changes, but info
1785 * Bug fix: LoadGame could not load a PGN game whose first move was
1786 castling (which is possible from setup positions).
1788 * Bug fix: we were ignoring illegal move messages from chess engines in
1789 modes where the engine is refereeing but not participating (EditGame,
1790 LoadGame, AnalyzeFile). The problem was in a workaround for a Crafty bug,
1791 where Crafty generates a bogus illegal move message if a "." (used by
1792 the PeriodicUpdates feature) is sent in analysis mode when the current
1793 analysis reveals a forced mate. Installed a different workaround (that
1794 works in most but not all cases) and reported the Crafty bug. Bob Hyatt
1795 replied with a fix, so the Crafty bug should be gone in Crafty 14.12 or so.
1797 * WinBoard only: enabled resizing board with the mouse. It snaps to the
1798 nearest (but not too much larger) predefined size.
1800 * The xboard default font is now sized according to piece size, just as
1801 clockFont and coordFont have always been.
1803 * Added more sizes: bulky, moderate, average, middling, mediocre, petite.
1805 * xboard only: Added Animate Moves and Click-Click Moving to Options menu.
1807 * xboard only: Added code to animate piece movement, from Hugh Fisher.
1809 * New feature: autoflag is implemented in MachineWhite, MachineBlack, and
1810 TwoMachines modes. If it is on and either a chess program or the user
1811 oversteps his time, xboard will automatically call the flag and end the
1812 game. This feature was requested by someone who runs matches between
1813 programs and wants to penalize GNU Chess for its habit of running slightly
1814 over at the end of a time control. I personally think it's pointless.
1816 * Fixed a bug in Zippy's pattern matching; he can now reply to ICC
1819 * Generate prettier notation for illegal moves. If a move is illegal only
1820 because it leaves the player in check, generate notation as if that were
1821 not illegal. For instance, if two knights are a knight's move away from
1822 f3, one on g1 and one on e5 that is pinned, the notation would be Nf3 to
1823 move the g1 knight, Nef3 to move the e5 knight. (Suggested by Philippe
1824 Schnoebelen.) In addition, if a move is illegal because the type of piece
1825 moved cannot go that way, would be jumping over another piece, etc., we
1826 give fully disambiguated coordinate notation; for example, Ng1g3, Ke1xe8,
1827 d2xd8=Q, etc. An alternative would be to still write Ng3 if there is only
1828 one knight on the board, or Ngg3 if the other knight is not on the g file,
1829 but life is too short to code up all this stuff, and perhaps the way I did
1830 it is better as it emphasizes that this move was really made despite being
1831 illegal. I wonder if the new PGN standard revision will speak to notation
1834 * Fixed gross bug from 3.6.2: if a chess program said "checkmate" and
1835 White was left on move, the PGN outcome was "1-0 {Black mates}" instead
1836 of "0-1 {Black mates}"! The bug occurred only for that specific string.
1838 3.6.2 -- Wed Jul 23 16:47:29 PDT 1997 Tim Mann
1840 * There was a bug in backing up from the end of a game against a chess
1841 engine, introduced when -reuse mode was added. Fixed.
1843 * Recognize "{" as terminating an ICS move list. Previously we needed to
1844 see a prompt (containing %), but occasionally ICC can send more stuff
1845 right after a move list with no prompt in between.
1847 * In WinBoard, -mm now implies -cp, so you don't get the startup dialog.
1849 * WinBoard startup dialog no longer sets -scp. People used to get
1850 confused because they would give the -fcp and -scp arguments, but omit
1851 -cp. This would bring up the startup dialog, which would set both -fcp
1852 and -scp to the value in the engine name box. Now you can change -scp
1853 only with the command-line argument. That will confuse some people too,
1854 but hopefully fewer. I think overall it's better than putting spaces for
1855 both -fcp and -scp in the dialog, which would puzzle newbies.
1857 * Bug fix: Analyze File mode now works in WinBoard.
1859 * Bug fix: WinBoard window no longer cuts off part of the bottom row if
1860 the menu bar wraps to a second line.
1862 * Accept game end messages of the form "PGN-result {comment}" from the
1863 chess engine, where PGN-result is 0-1, 1-0, or 1/2-1/2. Accept "resign"
1864 or "computer resigns" from the chess engine as a synonym for "0-1 {White
1865 resigns}" or "1-0 {Black resigns}". Accept any message from the chess
1866 engine containing "game is a draw" as a synonym for "1/2-1/2 {Draw}".
1867 Accept "White resigns" or "Black resigns".
1869 * Enable "Action / Draw" menu item in chess engine mode. It sends the
1870 command "draw" to the engine. Accept any message from the chess engine
1871 containing "offers a draw" as a draw offer. WARNING: Draw offers from the
1872 user and the engine (or from two engines) are not yet matched up by xboard
1873 in chess engine mode. Two engines could get into a loop offering each
1876 * Bug fix: Game end messages from the chess engine are always ignored in
1877 Zippy mode. Previously they could sometimes be processed, which was
1878 sometimes making Zippy hang at the start of a new game that followed
1879 quickly after an old one.
1881 * Zippy can now respond to titled players in channels. Zippy will avoid
1882 talking to himself in a channel if he knows his own name.
1884 * Bug fix: in colorization arguments, the bold setting was being ignored
1885 if the background color was defaulted. (xboard only.)
1887 * Extended ParseFEN to accept Crafty 12.2's interpretation of FEN.
1888 If fewer than 8 squares are given in a row, or fewer than 8 rows are
1889 given, the uncovered squares are empty. Also, there can be a / after the
1892 3.6.1 -- Sat May 17 01:02:33 PDT 1997 Tim Mann
1894 * Bug fix: Hitting escape while entering a password on WinBoard no longer
1895 sets the font color back to black (which made further typing visible).
1897 * Bug fix: On Windows NT 4.0, WinBoard /ics /icshelper=timestamp would
1898 often hang if you tried to exit with the Exit menu item, the [X] button,
1899 etc. The same fix may also have corrected the problem where running a
1900 chess program with /xreuse would sometimes crash Windows 95 (but not NT)
1901 when the chess program was killed and quickly restarted.
1903 * Bug fix: Periodic Updates would not work if turned on after having been
1904 off. Also, the default was needlessly "off" in WinBoard.
1906 * Zippy bug fix: Continuing an adjourned game was totally broken. The
1907 wrong moves, or no moves at all, were being fed to the chess program.
1909 * WinBoard change: Giving -ics without -icshost now pops up the startup
1910 dialog with "Use an Internet Chess Server" pre-selected, so that you get a
1911 menu of chess servers instead of going directly to ICC.
1913 * Bug fix: WinBoard's SaveSettings was saving -icshost, -icsport, and
1914 -icshelper in winboard.ini. This causes a problem if you use a different
1915 icshost later that needs the default values for icsport (5000) and
1916 icshelper ("", meaning none).
1918 * Disabled complaints about unexpected "[Ii]llegal move" messages from
1919 the chess program; we still get them at times.
1921 * Greatly simplified the code for Move Now and SIGINT (ATTENTION). Fixes
1922 the bug where Move Now did not work with GNU Chess in WinBoard, and
1923 several more obscure bugs as well. Reintroduces a minor bug: GNU Chess might
1924 not think on your time after a Move Now command. Trying to fix this
1925 causes too many other problems. Documented change in engine-intf.txt.
1927 * Cleaned up code for obtaining ratings from ICS. It was kludgey and may
1928 have had bugs on systems with no "Creating:" message. It should fail
1929 gracefully there, just not finding the ratings.
1931 3.6.0 -- Thu May 8 19:55:58 PDT 1997 Tim Mann
1933 * WinBoard now has right-button context menus in the ICS Interaction
1934 window. Some of the items do immediate commands on the player name you
1935 have selected or pointed to. (Suggested by Paolo Casaschi.) Also, the
1936 middle button or shift+right does a immediate Copy and Paste.
1938 * Fixed a bug in Zippy's wild rejection. The bug was causing Zippy to
1939 reject all forms of wild. Now it rejects only 1, 9, 16, 17, and 24, as
1940 was intended. These variants have different rules, while the other
1941 variants defined so far only have different starting positions.
1942 (Actually, wild 2, 3, and 4 never allow castling, but may sometimes by
1943 chance have king and rook start on squares where castling appears legal.
1944 This could cause a problem later.)
1946 * Zippy now resumes adjourned games by feeding the chess program
1947 the move list instead of the position. Setting -getMoveList to False
1948 restores the old behavior. Feeding in the move list is better because
1949 it enables the chess program to correctly handle en passant legality,
1950 castling legality, draw by repetition, and draw by the 50 move rule.
1952 * Added a WinBoard startup dialog for people who run WinBoard.exe without
1953 using the Start menu or reading the help file. Instead of being dumped
1954 directly into GNU Chess mode, you now get a menu of choices. You now have
1955 to give the new WinBoard -cp option to go directly into chess engine mode.
1956 I did not add this feature to xboard.
1958 * Handling of "illegal move" from Crafty is now back on. (It was turned
1959 off in 3.4.6; see below.) Crafty 12.0 doesn't seem to send bogus ones
1960 anymore. I did have to suppress sending time and otim in analyze mode to
1961 make this work, but there is no harm in that.
1963 * Zippy now sends "gameend" to ICS at the end of each game. You can alias
1964 this to "seek" or whatever you like.
1966 * Added Crafty support for Move Now, using the "?" command. We test
1967 whether this command exists by trying it once at the start of the first
1968 game, before it really makes sense. If we don't get a message like
1969 "Illegal move ... ?", we assume it's OK. (We're careful about this
1970 because sending a "?" to GNU Chess on Move Now keeps it from pondering the
1971 next move as it should.)
1973 * Added support for a tellusererror command from the chess engine. See
1976 * Attempted to make engine-intf.txt complete.
1978 * Minor fixes/cleanup to GameEnds code, to be sure we always interrupt
1979 when needed, and always undo an extra move generated by stopping the chess
1980 program while it is thinking.
1982 3.5.7 -- Sat May 03 22:37:44 PDT 1997 Tim Mann
1984 Beta release of both xboard and WinBoard.
1986 * Updated xboard documentation. I really wish the man page was built from
1987 the info file instead of being separate! It's a pain to update them both.
1989 * Updated documentation of the interface between XBoard/WinBoard and chess
1990 programs, and renamed it to engine-intf.txt.
1992 * Added support for tellics, telluser, and askuser commands from the chess
1993 engine. See engine-intf.txt.
1995 * Various bug fixes. On WinBoard, 256 color displays are finally handled
1996 right; no more color flashing when you switch windows unless the colors
1997 really need to be updated. Also, I think the problem of the console font
1998 failing to change or changing back by itself is finally fixed.
2000 3.5.6 -- Tue Apr 29 03:08:00 PDT 1997
2002 Beta release, WinBoard only. ChangeLog was out of date in release,
2005 * Added ICC timestamp and FICS timeseal to WinBoard distribution. These
2006 are my own ports to Win32, based on and used by permission of the owners
2007 of the proprietary source code (Daniel Sleator for timestamp, Henrik Gram
2008 for timeseal). The owners permit these programs to be distributed only in
2009 binary form (to help prevent cheating), so to avoid running afoul of the
2010 GPL, I have kept them as separate programs, not linked into the WinBoard
2011 address space. Updated Start menu icons to use them.
2013 * Miscellaneous smaller changes.
2015 3.5.5 -- Fri Apr 25 03:06:00 PDT 1997
2017 Beta release, WinBoard only. ChangeLog was out of date in release;
2020 * Added simple sound support to WinBoard.
2022 * Updated WinBoard documentation.
2024 * Internal implementation of the telnet protocol is now more complete.
2025 You can now hop through a VMS host on the way to ICS. For example, do
2026 "xboard -ics -icshost vms.host.edu -icsport 23", then log in. Do not use
2027 the -telnet flag; that says to use an *external* telnet program. To avoid
2028 double echoes, you need to force character mode in VMS telnet after
2029 connecting from VMS to ICS. Do "^]^Mset mode char^M^M".
2031 * Display opponent names in the title bar for MachineWhite, MachineBlack,
2032 and TwoMachines modes.
2034 * WinBoard now has an installer, built with InstallShield. The installer
2035 works with a binary-only distribution. Sources are still freely
2036 available, but now separately.
2038 * Added SaveSettings to WinBoard, which saves current option settings to
2039 winboard.ini. Made sure all options can be saved and loaded, including
2040 fonts and com port settings.
2042 * If the game ends while you are dragging a piece, we now don't let you
2043 finish the move. Formerly the move was accepted and your opponent's clock
2044 would start running again.
2046 3.5.4 -- Fri Apr 18 01:15:24 PDT 1997 Tim Mann
2048 Beta test release of WinBoard and xboard. The documentation remains
2051 * Many fixes and improvements to new WinBoard user interface code.
2053 * In Zippy mode, avoid sending another copy of the same move to the chess
2054 program if ICS sends us another copy of the board image. Hard to believe
2055 it took me until now to diagnose and fix this problem!
2057 3.5.3 -- Sat Apr 12 19:49:33 PDT 1997 Tim Mann
2059 Beta test release of WinBoard and xboard.
2061 * Fixed fatal bug in WinBoard input handling.
2063 * Made code to stop chess program for reuse a bit smarter. Removed kludge
2064 of "white" in initString; it didn't work well, and is unneeded
2065 with Crafty 11.21 and later.
2067 3.5.2 -- Sat Apr 12 15:40:01 PDT 1997 Tim Mann
2069 Beta test release of WinBoard.
2071 * Ignore check and permit promotion to King during suicide games; no need
2072 to turn off TestLegality.
2074 * Renamed CheckLegality to TestLegality to avoid confusion with the chess
2077 * Added Rematch to Action menu.
2079 * WinBoard now has a custom ICS interaction window with scrollback, a
2080 separate line for input, and colorization. Accelerators that conflict
2081 with normal editing keys were changed (by requiring Alt+) so they can work
2082 in both the console and the main window.
2084 * WinBoard error popups are now non-modal and disappear when you make a
2085 new move, as in xboard.
2087 * Configure now defaults to --disable-ptys on all systems. If anyone has
2088 an ancient SysV system where pipes don't work with select, they can still
2089 do "configure --enable-ptys" explicitly. I would appreciate getting a bug
2090 report if this happens to anyone, with complete output from configure and
2093 * "make install" now makes the installation directories too.
2095 * Fixed a bug that would cause an "Illegal move" message for Black from
2096 GNU Chess to be incorrectly considered bogus.
2098 * Handle name changes during an ICS game (FICS bname and wname commands).
2100 * You can force both chess programs to be killed at the end of each game
2101 by turning off the reuseChessPrograms option. There are still some
2102 problems with reusing Crafty even in version 11.20.
2104 * Now the second chess program stays around by default too, if it ever
2107 3.5.1 -- Sat Apr 5 16:47:48 PST 1997 Tim Mann
2111 * Don't kill off and restart the chess program for each game; keep the
2112 same one running, using the "new" command to start a new game. This
2113 change works around the problem in Windows 95 that makes WinBoard crash it
2114 at times, and is generally desirable to make new games start faster. The
2115 second chess program (for TwoMachines) is still killed at the end of the
2116 game, and unfortunately this can still crash Windows 95. Temporarily
2117 added "white" to the initString to make this work with Crafty 11.20, which
2118 has a minor bug in "new". Older versions of Crafty have worse bugs in
2119 "new"; they should not be used with this version of xboard.
2121 * Support for FICS suicide chess: Parse illegal moves (that leave King in
2122 check) in game history. If CheckLegality is off, allow promotion to King
2123 and illegal moves in game files. We still generate e2e4 style notation
2126 * Handle FICS "has timeseal; checking" message.
2128 * Changed the coords from white back to black; this was a bug.
2130 * Fixed problems compiling with K&R compilers.
2132 * Fixed an old bug in RegisterMove that was crashing cmail on some systems
2135 3.5.0 -- Thu Jan 2 16:59:49 PST 1997 Tim Mann
2137 Thanks to Frank McIngvale for much of the work on versions 3.4.4 and above!
2139 * Fix Crafty resumed game time bug (frankm)
2141 * Word wrap text in Analysis window (frankm)
2143 * More debug info for XPM loading (frankm)
2145 * Replaced config.sub, config.guess, etc., with up-to-date versions from
2146 autoconf 2.12. Hopefully this will fix problems on Pentium Pro machines.
2148 * Removed some Makefile gunk that was causing looping for one person.
2150 3.4.7 -- Thu Dec 19 14:22:41 PST 1996 Tim Mann
2152 All changes from Frank:
2154 * Retrieve ratings from ICC (and FICS, etc., when they add the Creating:
2155 message), save them in the PGN tags, and pass them to Crafty in Zippy mode.
2157 * Add settable time delay between characters in ICS login script.
2159 * Colorize messages like personal tells. Fix false recognition of channel
2162 * Pass "tells" from Crafty through to ICS (in Zippy mode).
2164 * Implement ~/ filename convention from C shell for game and position file
2167 * ZIPPYACCEPTONLY feature for testing.
2169 3.4, patchlevel 6 -- Sat Nov 23 16:58:50 PST 1996 Tim Mann
2171 * Put recognition of "illegal move" messages from Crafty for
2172 illegal castling, etc., inside an #if that is currently turned off,
2173 because of a bug in Crafty that generates bogus "illegal move" messages
2174 after some moves that are actually legal and accepted by Crafty.
2176 * Added -checkLegality option; previously this could not be turned off.
2178 * Fixed an old bug in finding default board size parameters.
2180 * Differentiated among channel tell, kibitz/whisper, and personal tell/say.
2182 * Fixed a bug in detecting Xpm in the configure script.
2184 3.4, patchlevel 5 -- Mon Nov 18 16:22:53 PST 1996 Tim Mann
2186 * Added zic2xpm to the kit; it had been omitted by mistake.
2188 * Added some default colors for -colorize
2190 3.4, patchlevel 4 -- Sat Nov 16 18:10:17 PST 1996 Tim Mann
2192 This is meant to be a beta release in preparation for version 3.5.
2194 * Added InfoXBoard and ManXBoard to the Help menu.
2196 * Made Frank's ICS input box optional, defaulting to off.
2198 * Merged in Frank McIngvale's XbKit. Many new features, including
2199 -clickClick mode, the Analysis modes, piece flashing, ZIICS import,
2200 ICS text colorization, and the ICS input box. Many thanks to Frank for
2201 supplying and documenting this code.
2203 3.4, patchlevel 3 -- Mon Nov 11 18:23:14 PST 1996 Tim Mann
2205 Small set of changes made while Frank McIngvale was working on XbKit in
2206 parallel. Unreleased in this form.
2208 * Updated zippy.README.
2210 * Removed useless X event handler and removed strange code for copying
2211 form translation table to board that worked around the bug it caused.
2212 This makes changing bindings in .Xdefaults more straightforward.
2214 * Now pressing the Control key steps back one move, and releasing it steps
2217 * Moved quit from "q" to "Q" for greater safety.
2219 * Use "unobserve" instead of "observe" to stop observing; needed on FICS.
2221 * Support for interface variable.
2223 * Strip titles from people who are talking to us, so (for example) Zippy
2224 won't try things like "tell Darooha(*) hello". Needed on FICS.
2226 3.4, patchlevel 2 -- Tue Jul 9 19:06:42 PDT 1996 Tim Mann
2228 This patchlevel is not planned to be an announced release. It's in
2229 preparation for integrating Frank McIngvale's XbKit. It mostly contains
2230 minor fixes I've accumulated since 3.4.pl1.
2232 * WinBoard /telnet option now fires up an external program, as
2233 with xboard, instead of trying to use a feature of NT 3.1 that does not
2234 exist in later versions of NT or in Windows 95. ChangeLog for 3.4.pl1
2235 said this had been implemented there, but it really wasn't.
2237 * Indicating player to move by the icon color now works under Windows 95.
2239 * WinBoard now kills the chess program when you exit using the system menu
2240 or the [X] button. Thanks to Michael Lowe.
2242 * Minor changes to Zippy, including: Now understands wild challenges on
2243 FICS; these used to crash it. Removed limit on how fast a game will be
2244 accepted. Use "set formula ..." on the chess server to limit this if you
2245 are using GNU Chess. Now sends correct opponent name to Crafty.
2247 * Added some missing default values to documentation. Thanks to Stuart
2250 * Bugfix: Trying to print "No fonts match pattern" error message would
2251 crash. This can happen to Linux users who don't install Helvetica, for
2254 * Bugfix: Defaulting feature in -size n,n,n,n,n,n would put us in an
2257 * Added more directories to search for Athena widgets on HPUX.
2259 * New cmail (3.12) from Evan Welsh; includes small fix from Kayvan Sylvan.
2261 * Recognize "illegal move" messages from Crafty for illegal castling, etc.
2263 * Bugfix: "name" command added to zippy.c for Crafty was producing error
2264 message if GNU Chess was in use.
2266 * In bughouse mode, suppress holding messages from console window; show
2267 holdings only in banner.
2269 * Minor fixes/cleanup to Makefile.in and configure.in.
2271 3.4, patchlevel 1 -- Mon Dec 11 13:43:12 PST 1995 Tim Mann
2273 * This patchlevel updates WinBoard to match xboard, and includes a few
2274 fixes and minor improvements. "-size tiny" and "-size n,n,n,n,n,n"
2275 are still not implemented for WinBoard.
2277 * Installed support for Crafty based on code from Bob Hyatt.
2278 Currently the only documentation for this is in the FAQ, and a few
2279 things don't work with Crafty 8.23. Please do not report these
2280 problems as bugs in either xboard or Crafty. Bob and I know about
2281 them. The worst ones (if not all of them) should be fixed in Crafty
2284 * Changed the kludge command we send when gnuchess wants to print
2285 something that doesn't end with a newline, from "help" to "bogus".
2286 This works because the error message gnuchess prints ends with a
2287 newline. It also improves compatibility with Crafty, which doesn't
2288 need the kludge, but for which sending "help" causes a problem.
2290 * Don't draw grid at all if lineGap is 0; previously we drew the grid
2291 with X "0-width" lines (usually 1 pixel wide) and then overwrote it.
2293 * Makefile: Removed xboard.info from "all" target so we won't try to
2294 rebuild it, because this fails on hosts that don't have makeinfo
2295 installed. Other minor fixes to "clean" targets, etc.
2297 * Fixes and cleanup to Auto Comment code that handles continuation
2298 lines and highlighting.
2300 * Auto Observe now tries to observe the game from the point of view of
2301 the player who was on your gnotify list. Requested by rng.
2302 Limitations: We can't tell which player it was unless you have ICS
2303 highlighting turned on. Also, currently "observe foo" works as
2304 required (observing from foo's point of view) only on ICC, but FICS
2305 will probably implement this soon.
2307 * "-size tiny" now makes the default font smaller automatically. This
2308 was implemented by introducing an extra Form widget in the hierarchy
2309 for all xboard windows, named either normalLayout, smallLayout, or
2310 tinyLayout. So you can have resource specifications that apply only
2311 to certain layouts; in particular, XBoard*tinyLayout*font.
2313 * Bug fix: EditGame or EditPosition while playing or examining still was
2314 not really being permitted.
2316 * WinBoard bug fix: On the EditPosition menu, King did not work.
2318 * Added text catalog of WinSock error messages to WinBoard, because
2319 Microsoft still has not put them in the system message catalog.
2321 * Removed support for older ICS game-ending messages that do not have
2322 a PGN result token (*, 0-1, 1-0, or 1/2-1/2) after the closing '}'.
2323 The code for older messages was sometimes firing on the newer
2324 messages, due to parsing ambiguity. If the current code sees an old
2325 message, it will understand that the game is over, but will always
2326 display * as a result token instead of trying to guess the result by
2327 interpreting the text message.
2329 3.4, patchlevel 0 -- Tue Nov 21 01:02:50 PST 1995 Tim Mann
2331 * This patchlevel was released for xboard only.
2333 * Updated the info file. It should now be as up-to-date as the man page,
2334 with good English except in the parts that pertain only to AmyBoard.
2336 * Added "-size tiny", requested by Bob Hyatt. Also cleaned up bitmap
2337 support and added "-size n,n,n,n,n,n" to allow arbitrary-sized bitmaps,
2338 if the actual bitmaps are supplied by the user.
2340 * Updated bughouse support.
2342 3.3, patchlevel 4 -- Sat Nov 18 02:27:21 PST 1995 Tim Mann
2344 * Unreleased beta that works with preliminary FICS bughouse code. Will
2345 need changes before release to track FICS message changes.
2347 * Removed use of .EX macro from man page. It is not supported by some
2348 nroff -man macro packages, notably the one on Slackware Linux. Switched
2349 to boldface for references to xboard and other commands within the man
2350 page, as this seems to be the modern way.
2352 * Bug fix: If ICS rejected a move, it was correctly undone on the board,
2353 but the message widget still displayed the bad move. Reported by DAV.
2355 * Normally, xboard in ICS mode fetches the move list whenever the board
2356 display switches to a new game. Doing this is now an option
2357 (getMoveList) that can be turned off, which is useful if you are watching
2358 multiple blitz games. Requested by rng.
2360 * Move list fetching code is now smarter: it ignores a move list if it is
2361 not for the right game.
2363 * Added support for bughouse as implemented on FICS. Holdings are shown
2364 in the window title in place of the strength numbers. A menu on mouse
2365 buttons 2 and 3 (same on both) lets you drop pieces. There is no checking
2366 as to whether you actually hold the piece you are trying to drop; we rely
2367 on ICS to check that. Notation of the form P@f7 is generated and parsed.
2368 The mate detector does not understand that non-contact mate is not really
2369 mate in bughouse, but this does no real harm. It results in a "#"
2370 suffix being displayed on the move notation, but xboard does not assume the
2373 * Bug fix: Promotion to a knight was not working with ICC! Thanks to
2374 Wendigo for the report.
2376 * Bug fix: Special pty code for host types *-*-aix3* and *-*-irix3*
2377 (supplied from configure.in) had a bug that would cause childio.c to
2378 fail to compile, due to a "continue" that was not within a loop.
2380 * Bug fix: In pgntags.c, memory was being freed while still in use. One
2381 symptom this caused was that on some machines, cmail would fail with a
2382 message that it could not find the BlackNA tag. The error was in some
2383 submitted code that I included in version 3.2.pl3 without reading
2384 carefully enough. Anders Forberg noticed the symptoms, and Evan Welsh
2385 (who had nothing to do with causing the bug) found the bug and submitted a
2386 fix; thanks to them both.
2388 * Removed restriction against using EditGame while playing, observing,
2389 or examining on ICS. You still get a warning popup.
2391 3.3, patchlevel 3 -- Sat Sep 16 11:44:05 PDT 1995 Tim Mann
2393 * Bug fix: Going directly from MachineWhite to TwoMachines mode would kill
2394 off the second chess program after Black's first move.
2396 * Added -timeIncrement feature. Thanks to Joel Rivat.
2398 * Deleted code that tries to keep you from observing more than one game,
2399 or observing while playing or examining. There is actually no problem in
2400 doing this, except that every time an update comes in from a different
2401 game than is currently being displayed, xboard fetches the history of the
2402 new game, which may be time-consuming if you are on a slow link.
2404 * Fixed configure so as not to crash when neither lex nor flex is found.
2405 lex or flex is needed only if the user wants to rebuild parser.c. Thanks
2406 to Phil Humpherys for reporting the crash.
2408 * Bug fix: config.h.in used #define instead of #undef for some macros used
2409 in the pty code in childio.c. This causes the code to fail to compile on
2410 some architectures, because the symbols are supposed to be undefined, not
2411 defined to empty, when they are not set in configure. Bug originated in
2412 3.3.pl0 when config.h was introduced. Thanks to Phil Humpherys for report.
2414 * Bug fix: ShowThinking would not show anything when current position had
2415 no move to display in the move window. E.g., if position was created by
2416 LoadPosition or EditPosition.
2418 3.3, patchlevel 2 -- Mon Aug 28 11:11:11 PDT 1995 Tim Mann
2420 * Zippy code was omitted from xboard-3.3.pl1 by mistake; now included.
2422 * For WinBoard, added hint to help file that you may need to turn off
2423 LocalLineEditing while typing dialing commands to your modem.
2425 3.3, patchlevel 1 -- Sat Aug 19 15:13:30 PDT 1995 Tim Mann
2427 * Zippy distribution is no longer separate from regular xboard distribution.
2429 * Deal properly with Show Thinking output from GNU Chess when it is
2430 thinking on its opponent's time. In TwoMachines mode this output is
2431 suppressed to avoid interfering with the output from the machine that is
2432 on move; in other modes it is displayed (including the move that GNU Chess
2433 is predicting the user will make next). GNU Chess produces this output
2434 only if it is built without -DQUIETBACKGROUND defined; this symbol is
2435 defined by default in patchlevels before pl75, but undefined by default in
2438 * Bug fix: Handling of initial board position in move list for wild games
2439 was broken, so wild games could not be observed and adjourned wild games
2440 could not be continued. Thanks to "Maximum Entropy" for the bug report.
2442 * Added feature: algebraic notation now shows "+" indicator for check
2443 and "#" for checkmate, as called for in PGN standard. Thanks to Kevin
2444 Maher for the suggestion.
2446 3.3, patchlevel 0 -- Thu Jul 27 22:21:07 PDT 1995 Tim Mann
2448 * Changed configuration to use a config.h file instead of passing zillions
2449 of -D options on the cc command line.
2451 * Merged a small fix and some updates to the texinfo file from Jochen
2452 Wiedmann. The texinfo file still needs work.
2454 3.2, patchlevel 5 -- Tue Jul 18 20:29:39 PDT 1995 Tim Mann
2456 * Beta test release of xboard only.
2458 * Updated WinBoard code to include new xboard features.
2460 * Added texinfo file from Jochen Wiedmann to the release, but not as the
2461 primary documentation. It needs updating, and the English needs work.
2462 I did make a few improvements, mostly to change incorrect uses of @var to
2463 either @samp or @code as appropriate.
2465 * Merged in code changes to 3.2.pl4beta from Jochen Wiedmann.
2467 * Fixed EditComment; did not pop up window in previous beta.
2469 * Added AutoComment feature.
2471 * Added GameListDestroy to disable the outdated game list popup in cases
2472 where we load a new game file without building a new popup.
2474 * Added yyskipmoves feature to parser.l to speed up building of gamelist.
2476 * gamelist.c wouldn't compile with a non-ANSI compiler. Fixed.
2478 * Change to yy_text handling in patchlevel 3 still had problems. Can't
2479 use AC_DECL_YYTEXT in configure.in, because that defines YYTEXT_POINTER
2480 according to whether the lexer on the current host makes yytext a pointer.
2481 But most people will be using a parser.c that was generated on another
2482 host and shipped with the package.
2484 3.2, patchlevel 4 -- Sun Jun 25 19:13:43 PDT 1995 Tim Mann
2486 * Beta test release of xboard only.
2488 * Added FIREWALLS section to man page.
2490 * Changed -icsport to be a string. Now with the -telnet option,
2491 specifying -icsport "" suppresses the second argument to telnet.
2493 * Added EditTags feature. Removed AboutGame from menu, because EditTags
2494 subsumes it. EditTags suggested by Jochen Wiedmann and first implemented by
2495 him in AmyBoard. xboard implementation is my own.
2497 * Fixed some missing or incorrect prototypes.
2499 3.2, patchlevel 3 -- Sat Jun 3 18:57:38 1995 Tim Mann
2501 * Beta test release of xboard only.
2503 * New version of cmail from Evan Welsh, to fix compatibility problems with
2506 * Added game list feature on Load Game, based on code from Jochen
2507 Wiedmann. Integrated it with cmail.
2509 * Several bug fixes from Jochen Wiedmann, including one to my yy_text
2510 workaround for the difference in the type of yytext between lex and flex.
2512 * Handle clock pause on FICS.
2514 * Suppress clocks in untimed FICS games (time control 0 0).
2516 * Rebuilt configure script with autoconf 2.3. This fixes a bug in
2517 configuring for X11R6, where -lSM -lICE would not be added when needed.
2519 * Fixed inconsistent type declarations on IntSigHandler and
2520 CmailSigHandler. Bug report from Josh Daynard.
2522 * backend.c wouldn't compile with a non-ANSI compiler. Fixed.
2524 3.2, patchlevel 2 -- Tue Feb 7 14:50:30 1995 Tim Mann
2526 * Minor release of both xboard and WinBoard.
2528 * Added recognition of some FICS messages. On the other hand FICS is also
2529 changing some of its messages to match what xboard already recognizes.
2531 * Temporarily went back to using "promote" command on ICS instead of
2532 "a7a8=Q", because FICS doesn't implement the latter yet.
2534 * We now avoid using overlapped I/O on pipes in WinBoard, to make Windows
2535 95 beta 2 happy. This lets WinBoard work with GNU Chess on Windows 95!
2537 * Installed patches from Jochen Wiedmann to coordinate with Amiga XBoard.
2539 * Installed patch to cmail bug in LoadGame from Evan Welsh.
2541 * Bugfix: checkmate and stalemate moves entered with EditGame in ICS mode
2542 were not being handled correctly. Bug was in GameEnds().
2544 * Implemented EchoOn and EchoOff for xboard, using system("stty echo\n").
2545 Now passwords won't be echoed when you connect directly to ICS. Also,
2546 telnet negotiation characters aren't displayed (when possible).
2548 * Implemented more of the telnet protocol. Now connecting to a telnet
2549 server with "-icsport 23" should work even without giving the -telnet
2550 option. The telnet is in "old line-by-line mode".
2552 3.2, patchlevel 1 -- Sat Dec 10 13:50:46 1994 Tim Mann
2554 * This patchlevel released for WinBoard only.
2556 * winboard.c: Fixed ConsoleInputThread(). Needed to change CRLF to LF,
2557 not to CR. This was stopping normal /ics mode from working. Thanks to
2558 Asher Kobin for the bug report.
2560 * winboard.c: Fixed Raw(), EchoOn(), EchoOff(). Now they take effect
2561 immediately, not on the next console read after the one in progress.
2563 * winboard.c: Attempted to make WinBoard work with gnuchessx running
2564 directly on Windows (not remotely via rsh). It now works on NT, but only
2565 if gnuchess is told not to think on its opponent's time ("easy\n" removed
2566 from initString). The problem seems to be that GenerateConsoleCtrlEvent
2567 is not doing anything. On Windows 95 beta 2, we get error messages on
2568 both reading and writing to gnuchessx; I didn't investigate why.
2570 3.2, patchlevel 0 -- Wed Dec 7 13:23:36 1994 Tim Mann
2572 * Thanks to all the beta testers who gave me feedback: Josef Nelissen,
2573 Steve Booth, Evan Welsh, Dima Dakhnovsky, Chris Petroff, Peter Jansen,
2574 Derek Terveer, Michel van der List, Richard Lloyd, Shelly Mistry, and Mike
2575 Lee. Sorry if I forgot anyone. Thanks to Virendra Kumar Mehta for
2576 information about DYNIX/ptx.
2578 * Don't exit on keyboard EOF unless we get two in a row.
2580 * WinBoard only: added -localLineEdit switch to allow turning off local
2581 line editing if you really want to. It is still a bad idea to let the
2582 echoing be done remotely, however; see below.
2584 * Fixed some configure problems on HP-UX. [Steve Booth]
2586 * Fixed (I hope) configure problem on SunOS 5.3/Solaris 2.3. [Josef Nelissen]
2588 * cmail bugfix from Evan Welsh (cmail 3.4).
2590 3.1, patchlevel 9 -- Fri Dec 2 23:54:56 1994 Tim Mann
2592 * Beta distribution only
2594 * Always do local echo/edit of user typing in ICS mode. Doing the echo
2595 downstream may seem nicer in some modes, and it can be hard to turn that
2596 echo off, but the echoed characters can be interleaved with ICS output
2597 and make it impossible to parse correctly. For xboard this involved only
2598 a change to recommendations in the man page, as Raw() isn't implemented.
2599 For WinBoard, removing Raw() made a real difference. Added code in
2600 WinBoard to change /r/n back into /r on keyboard input, as we get the
2601 former when Raw() is not called.
2603 * Do not issue ICS "refresh" command after we start to observe a game
2604 unless we get to the next prompt without seeing a board image. Newest
2605 version of ICS doesn't require this refresh, but old versions around still
2608 * cmail bugfix and small code cleanup in LoadGame, from Evan Welsh.
2610 * Added keyboard accelerators N/P for LoadNextGame/LoadPreviousGame. Evan
2613 * Using "-" on the command line as a filename for loading (saving) games
2614 or positions specifies the standard input (standard output). Alain Picard
2617 * On WinBoard only, a command line option without a leading '-' or '/' is
2618 now taken as the value of -lgf.
2620 * Changed to not use stdin, stdout, stderr as initializers in backend.c;
2621 needed for GNU libc compatibility. You also must build parser.c with flex
2622 (not lex) if you are using GNU libc, to avoid having the same problem
2625 * Changed WinBoard to avoid using "overlapped" input on the console. It
2626 now seems to fully work on Windows 95 beta 2.
2628 * Improved comment popups on WinBoard. Now newlines are handled properly,
2629 and the plain Comment popup window doesn't disappear and reappear when we
2630 step to a new move with a new comment.
2632 * Fixed bugs in detecting the absence of the time and otim commands.
2634 * Added built-in implementation of rcmd protocol to WinBoard. Windows NT
2635 does not implement passing signals through rsh, and Windows 95 does not
2638 * Added -remoteUser option.
2640 3.1, patchlevel 8 -- Mon Nov 28 15:26:07 1994 Tim Mann
2642 * Beta distribution only
2644 * Rearranged ChangeLog file into reverse chronological order to be closer
2647 * Integrated new cmail code from Evan Welsh (including cmail RCS rev 3.2).
2648 Includes a bug fix to TruncateGame.
2650 * Updated ICS address to be chess.lm.com.
2652 * Bug fixes to handling the aftermath of FatalError. Thanks to Chris
2653 Petroff for the bug report.
2655 * Test for remsh before rsh, other fixes for HP-UX. Thanks to Richard
2656 Lloyd. I wasn't able to do all the things he suggested, so there may
2657 still be some rough edges in building on HP-UX. See the FAQ file for hints.
2659 * Bug fix; added missing check for HAVE_SYS_SYSTEMINFO. Thanks to Josef
2660 Nelissen for testing on Solaris 2.x.
2662 * Updated WinBoard to match xboard. (WinBoard still has a few option
2663 dialogs that don't exist in xboard.)
2665 * Changed Hint output to a popup.
2667 * ShowThinking output and move output no longer overwrite each other.
2668 ShowThinking output won't appear if the displayed position is not current.
2669 ShowThinking output in TwoMachines mode made clearer and documented.
2671 * Implemented --enable-ptys and --disable-ptys arguments to configure.
2673 * Fixed Book and Hint code to work over a pty with echo enabled and tabs
2674 expanded to spaces. Thanks to Dima Dahknovsky for the bug report.
2676 * Moved Attention calls from all over xboard to one place, inside
2679 * Added bulletproofing to ShowThinkingEvent.
2681 * Added code to handle "refresh N" boards that come in from ICS properly,
2682 assuming ICS is changed to mark them with a new relation code (-3).
2684 3.1, patchlevel 7 -- Sun Nov 13 22:16:01 PST 1994 -- Tim Mann
2686 * Beta distribution only
2688 * Changed ShowThinking to just show the current best line in the
2689 DisplayMessage area, instead of dumping everything to stdout.
2691 * Installed new cmail (RCS rev 3.1) and cmail.man (RCS rev 1.10), and
2692 changes to cmail code in backend.c, from Evan Welsh.
2694 * Miscellaneous minor fixes.
2696 3.1, patchlevel 6 -- Fri Nov 4 12:53:53 PST 1994 -- Tim Mann
2698 * This patchlevel was not actually released to anyone.
2700 * Updated the pty code to be based on GNU Emacs 19.24, and moved it to a
2701 separate file. It was hard to split out just the pty configuration from
2702 all the stuff emacs does with its custom configure script and .h files,
2705 * Converted from imake to GNU autoconf. This was a serious upheaval.
2707 * Put in code to help trap "error gathering move list" problem reported by
2708 Michel van der List if it recurs. I couldn't reproduce it.
2710 3.1, patchlevel 5 -- Mon Oct 31 21:12:00 PST 1994 -- Tim Mann
2712 * Beta distribution only.
2714 * We now test for checkmate or stalemate in EditGame mode after every user
2715 move, and in LoadGame mode whenever we hit the end of a game without
2716 seeing a PGN end marker. cmail needs an update to deal with this
2717 correctly; Evan promises one.
2719 * Bugfixes in new move generator. Thanks to Mike Lee for reporting one of
2722 * Imakefile was omitted from patchlevel 4.
2724 3.1, patchlevel 4 -- Mon Sep 19 18:19:46 PDT 1994 -- Tim Mann
2726 * Beta distribution only.
2728 * The move generator includes a mate tester. Initially this is used only
2729 by cmail, and even that usage needs further work.
2731 * Wrote a true move generator and used it to replace all the move
2732 disambiguation and legality checking code in parser.l. The move generator
2733 is capable of dealing correctly with en passant and castling availability,
2734 but the rest of the program still does not keep track of this information.
2736 * Bug fix: xboard did not handle "foo has made you an examiner of game 23"
2737 message. Thus you could not use examine features until the next board
2738 came in, showing your new relation to the game. Thanks to POOKIEWOOKIE on ICS
2741 * Added AutoObserve feature. Thanks to Chris Petroff for the idea.
2743 * Added Book feature to use new gnuchess "bk" command. Mike McGann request.
2745 * Redid code to handle missing "time" command in gnuchess, because latest
2746 gnuchess no longer sends a response to this command.
2748 * Eliminated need for -DFLEX. Thanks to Michael Shields (Vladimir?) for
2751 * Added missing code to implement MoveNow in TwoMachines mode.
2753 * Added ShowThinking feature. Thanks to Richard Lloyd for the idea.
2755 * Applied patches from Evan Welsh; some fixes and improvements to the
2758 * Fixed bug in moving from EndOfGame mode to MachineWhite or MachineBlack,
2759 introduced in previous patchlevel. Also fixed related bug in ending a
2760 game in ICS mode; was entering EndOfGame mode instead of IcsIdle.
2762 * Added patch to implement internetChessServerLogonScript flag, from Kevin
2765 3.1, patchlevel 3 -- Wed Sep 7 13:22:07 PDT 1994 -- Tim Mann
2767 * Beta distribution only.
2769 * Merged in new cmail code from Evan Welsh. He added the ability to have
2770 more than one game per message, needed for official IECG matches. I added
2771 the ability to resign or offer/accept/decline a draw in a cmail game.
2773 * Bugfix: invalid -tc option caused segmentation fault; DisplayFatalError
2774 was called too early in initialization. Georges Honore reported this bug.
2776 * Decided to keep EndOfGame mode as an element of the user interface---it
2777 means that a gnuchess game or loaded game has ended, and the user must
2778 explicitly select EditGame to edit it, rather than just being able to
2779 enter more moves freely. But internally there is no longer an invariant
2780 tying this mode to whether the chess program is running.
2782 * Zippy bugfix: Was saving only the final position in the -sgf file when
2783 the game ended by something other than resignation or flag. Also fixed
2784 the longstanding bug that Zippy would think the final board of such a game
2785 was a new game and restart the chess program.
2787 * Now does a better job of faking castling availability in FEN. We still
2788 don't really keep track of it, but now at least we don't say that castling
2789 is still available when the king or rook is not on its home square.
2791 * Bugfix: Initial board of game history for wild games was going through
2792 too much processing, causing us to forget the game length, which is now
2793 needed by ParseGameHistory. This was causing problems with resuming
2794 adjourned wild games.
2796 * Updated ICS host to ics.onenet.net.
2798 * Zippy now accepts challenges where the opponent specified his color.
2800 * Added ZIPPYPASSWORD2 to let operator give commands directly to gnuchess.
2802 * Bitmap directory can include alternative icons now, too.
2804 * Handle "Game * (*) has no examiners" message from ICS.
2806 * Revamped window title and icon name selection.
2808 3.1, patchlevel 2 -- Sun Jun 12 17:16:28 PDT 1994 -- Tim Mann
2810 * "Beta" distribution for Zippy users only.
2812 * Bugfix: common.h was assuming that X11 type Boolean is char, which is
2813 not always true. This might have caused all sorts of obscure bugs!
2815 * Installed new bitmaps from Elmar Bartel as the default. Many thanks!
2816 The old bitmaps can be used by changing the "bitmaps" symbolic link before
2817 compiling xboard, or by using the -bitmapDirectory option at runtime.
2819 * Loading a game that ends with the PGN unfinished symbol ("*") now always
2820 leaves you in EditGame mode.
2822 * Added documentation of -icscomm to man page. Thanks to Maarten Remkes
2823 for the linux script.
2825 * ^C now kills gnuchess as well as xboard. Thanks to Dima Dakhnovsky for
2826 reminding me how to do this.
2828 * Bitmap icon color now indicates player to move. Stuart Cracraft
2831 * Changed piece bitmap flags to have just one flag, which points to a
2832 directory full of bitmaps, instead of a flag for each bitmap. Also
2833 changed bitmap naming convention.
2835 * "Connection closed by ICS" is no longer a FatalError popup. This was
2836 too annoying in the normal case where the user typed "quit".
2838 * Changed default font to 14 pixels instead of 10 points. This seems to
2839 make it close to the size I want it to be on more displays.
2841 * Major mode (GNU Chess, etc.) appears in title bar. Stuart Cracraft
2844 * Bug fix: EditGameEvent, MachineBlackEvent, MachineWhiteEvent, and
2845 TwoMachinesEvent were calling PauseEvent to get out of pause mode, which
2846 now has undesired side effects, such as advancing the display to the
2847 forwardMostMove. It works fine to just set pausing = FALSE instead.
2849 * IcsExamining mode now lets you access ICS edit position commands using
2850 the same popup menus as xboard's EditPosition mode. Thanks to DAV on ICS
2851 for inspiring the idea.
2853 * Corrected test for gcc on HP in Imakefile; thanks to Richard Lloyd.
2855 3.1, patchlevel 1 -- Wed Jun 1 16:25:11 PDT 1994 -- Tim Mann
2857 * Added parser.c.lex and parser.c.flex to the distribution.
2859 * Added HP gcc options to Imakefile, from Mats Nylen.
2861 * EndOfGame mode no longer highlights EditGame mode indicator, because the
2862 modes really do differ. I would like to get rid of EndOfGame mode in the
2863 future, at least as far as users can see.
2865 * Larger %a in parser.l, needed for RS/6000 users.
2867 * Minor improvements to Mail Move error messages.
2869 * When -debug flag is given to xboard, -v is passed to cmail.
2871 * Old Save Style uses "1. ..." instead of "1..." when black moves after a
2872 comment; more like xboard 3.0's actual style.
2874 * New version of cmail from Evan Welsh. Looks for UCB Mail in a more
2875 portable way and has some minor bug fixes.
2877 * Bug fix: Saving a FEN position while in EditPosition mode with black to
2878 play was showing white to play in the saved position.
2880 3.1, patchlevel 0 -- Fri May 20 16:36:15 PDT 1994 -- Tim Mann
2882 * This is the first general release since 3.0, patchlevel 9. Releases
2883 since then have been limited-distribution or beta releases.
2885 * Thanks to my version 3.1 beta testers: Dmitry Dakhnovsky, Ed Hanway,
2886 Richard Lloyd, Mike McGann, Shelly Mistry, Josef Nelissen, Chris Petroff,
2887 Jack Robertson, Michel van der List, Ky Macpherson, Derek Terveer, and
2888 Evan Welsh. Sorry if I've forgotten anyone who gave me feedback.
2892 * Minor cleanup on menu sensitivity code.
2894 * Integrated another even better version of cmail from Evan Welsh,
2895 including some code he supplied in xboard itself.
2897 * A few more fixes to cmail support.
2899 * Automatically update clocks after an ICS "moretime" command.
2901 * Handle ICS automatic examine mode (set examine 1) after a game.
2903 3.0, patchlevel 14 -- Tue May 17 13:41:44 PDT 1994 -- Tim Mann
2905 * Beta test release only.
2907 * Don't suppress prompt on first board of game being examined; otherwise
2908 it looks like nothing happened at all (i.e., like you're lagged).
2910 * Added StopExamining and StopObserving (Chris Petroff suggestion).
2912 * Made Reset do a refresh on ICS. John Chanak's original ICS code for
2913 xboard tried to do this; I finally decided it was a good idea after all.
2915 * Fixed bugs in handling updates that come in while you are pausing in
2916 examine mode. This is pretty tricky to do right.
2918 * Made un-Pausing immediately pop you to the current position. This is
2919 always necessary in examine mode, since the game may have changed under
2920 you; your remembered moves might no longer be right. So I made it do the
2923 * Took Detach Examine mode back out...used Pause mode for this instead!
2925 * Put in a trap for the GNU Chess bug of printing an Illegal Move message
2926 when its own hint move is illegal.
2928 * Attempted to fix a Zippy bug; bogus "exited unexpectedly" messages after
2929 it checkmates its opponent. This involved adding an argument to GameEnds
2930 to say who says it ended (ICS, GNU, etc.) and taking different actions in
2931 different cases. Unfortunately, this just restored an older Zippy bug, where
2932 Zippy restarts gnuchess when it gets the board with the final position,
2933 because GameEnds still puts xboard in EndOfGame mode. Sigh.
2935 * We now capture elapsed time on last move when getting game history.
2936 (Josef Nelissen bug report)
2938 * Rewrote code to redisplay last file title so it really works.
2940 * Fixed bug in oldSaveStyle.
2942 * Larger %a and %o were needed for lex.
2944 3.0, patchlevel 13 -- Mon May 16 16:26:22 PDT 1994 -- Tim Mann
2946 * Beta test release only.
2948 * FatalError popups stay on the screen now. If the error is really fatal,
2949 all functions are disabled, and the program exits when you press OK.
2951 * Redisplay last file title when using Load (Next/Previous/Same) Game.
2953 * Zippy understands new match challenge message format on ICS.
2955 * Added Revert command.
2957 * When examining a game on ICS, < > buttons do ICS backward/forward
2958 commands, unless you set the Detach Examine option. Thanks to Dima
2959 Dakhnovsky for the idea.
2961 * Fixed various minor problems in cmail mode.
2963 * cmail generates the tags now. New version of cmail from Evan Welsh.
2965 * cmail mode won't let you do MailMove unless the currently displayed
2966 position is exactly one move past the end of the game you loaded.
2968 * Fixed building of man pages in Imakefile
2970 * Updates to INSTALL file
2972 3.0, patchlevel 12 -- Sat May 7 21:10:03 PDT 1994 -- Tim Mann
2974 * Beta test release only.
2976 * Brought man page up to date.
2978 * Added Shift+R to resign from keyboard.
2980 * Some items on Action menu available in GNU Chess mode now.
2982 * Revamped Action menu.
2984 * Reordered functions in backend.c as a small step toward reorganizing
2987 * Generate TimeControl PGN tag.
2989 * Get type of ICS game (e.g., rated blitz) and save in PGN tags.
2991 * Bug fix: Clocks were not redisplayed when entering EditGame mode.
2993 * Bug fix: Clocks were not being redisplayed after loading a game file
2994 with -td 0, so they could show the wrong color active.
2996 * Bug fix: Chess programs would be killed and match mode would exit
2997 prematurely when loading a PGN game fragment ending with "*".
2999 * ICS command "sposition" no longer confuses xboard.
3001 * Integrated new version of cmail (with support code in xboard) from Evan
3004 * Added TruncateGame, MoveNow, RetractMove, and QuietPlay.
3006 * Bug fix: switching between MachineWhite and MachineBlack was not calling
3007 Attention(). Reported by Dino Dini.
3009 * More improvements to INSTALL and Imakefile.
3011 * Pack moves into 79 character lines in PGN output. We don't generate
3012 check indications, and we always break the line before the result,
3013 so this is not quite PGN export format.
3015 * Use FEN tag in PGN.
3017 * Improved finding and counting of game starts in save files.
3019 * Negative position or game numbers in -lpi/-lgi mean to seek to that byte
3020 offset. Hook for possible future features, not in man page.
3022 * Detect and handle absence of either "time" or "otim" commands in
3025 * Don't use "promote" command to ICS anymore.
3027 * Handle switching sides and taking back moves on FICS.
3029 * Handle flip state flag in style 12 board.
3031 * Handle examine mode on ICS.
3033 * Improved error popups for various kinds of illegal moves.
3035 * Suppress unasked-for hints from gnuchess (which it generates in post
3038 * Load/save position functions use FEN. Old style also supported.
3040 * Added detailed error messages if loading a bitmap file fails.
3042 * Small board has 2-pixel lines between squares instead of 3-pixel.
3044 * Added OldSaveStyle and AboutGame.
3046 * Renamed ForceMoves to EditGame.
3048 3.0, patchlevel 11 -- Tue Sep 21 15:25:36 PDT 1993 -- Tim Mann
3050 * The following changes were present in xboard 3.0, patchlevel 11, but the
3051 first group did not make it into WinBoard 3.0 until later. xboard
3052 3.0.pl11 was a limited-distribution release only, mostly to Zippy users.
3054 * Man page minor fixes.
3056 * Added a missing file close.
3058 * Removed automatic error popdown on Reset, which was destroying some
3059 error messages before they could be read.
3061 * Fixed char vs. unsigned char warnings on bitmaps.
3063 * Use ICS board style 12. Some improvements to ICS parsing.
3065 * Comment window is now labelled with the move the comment is on, and
3066 comments don't pop down when you step to the next move.
3068 * Save files now in PGN format.
3070 * Support for loading PGN files. PGN tags pop up when a PGN game file
3073 * More info in INSTALL and Imakefile about building for Suns (and
3076 * WinBoard 3.0 patchlevel 11 split off from an early version of xboard
3077 3.0 patchlevel 11, so it does not have all the features of that
3078 patchlevel. The following changes made it into both xboard and
3081 * Made Comment dialog non-modal in WinBoard.
3083 * EndOfGame mode is now more transparent. It looks like ForceMoves
3084 mode except that there is no chess program running.
3086 * Small bug fixes in clock management. Most noticeably, pausing when
3087 it is gnuchess's move now works as documented (again).
3089 * Add minimal support for -icscomm option. Not documented yet because
3090 I haven't sorted out the issues with setting the tty modes on the comm
3091 port device, or with locking it properly. But it's usable by wizards.
3093 * Don't restart the chess program upon Backward event from EndOfGame mode.
3095 * Suppress extra prompt after ICS sends us a board.
3097 3.0, patchlevel 10 -- Sat Sep 11 18:44:03 PDT 1993 -- Tim Mann
3099 * Beta test release only.
3101 * Zippy now plays chess. zippy.c and zippy.h are still not included
3102 in the standard distribution, but are available on request.
3104 * Switched to using style 12 on ICS.
3106 * Updated man page, and documented use of XBoard*form.translations to
3107 add more shortcut keys.
3109 * Added shortcut keys "d" to claim/offer/accept a draw, and "t" to
3110 call flag. Suggested by venu on ICS.
3112 * More explicit instructions in INSTALL file.
3114 3.0, patchlevel 9 -- Tue Sep 7 14:02:00 PDT 1993 -- Tim Mann
3116 * General release, minor update to 3.0.pl8.
3118 * Loosened checking on whether it's okay to start a move, to satisfy
3119 ICS ultra-blitz players. Now we don't check whether it's your turn
3120 until you let go of the piece.
3122 * Parser now recognizes "+-+" as meaning the game ended in a draw.
3124 * Got rid of S_NONE symbol, which seems to conflict with some symbol
3127 * Tweaked the man page. Clarified that there is currently no way for
3128 two people running copies of xboard to play each other without going
3129 through the Internet Chess Server.
3131 * Fixed a bug in color name conversion. Asking for two different
3132 colors whose names were the same in the first four characters would
3133 get you two copies of the first one. Thanks to Volker Zink for the
3136 * Improved confusing Usage() message.
3138 * Added a bunch of Sun information to the Imakefile and INSTALL file.
3139 Thanks to Ed Hanway, Arik Klingensmith, and others who responded.
3141 * Test for defined(WIN32) instead of !defined(unix).
3143 * Avoid using (void *) type with non-ANSI C compilers. Thanks to
3144 James Altucher for the bug report.
3146 3.0, patchlevel 8 -- Thu Sep 2 12:23:01 PDT 1993 -- Tim Mann
3148 * Note: Patchlevel 8 was the first non-beta release of xboard 3.0
3150 * Added cmail to distribution. Contributed (and still maintained) by
3153 * Bug fix: -queen option wasn't initializing menu check. Reported by
3156 3.0, patchlevel 7 -- Thu Aug 26 13:23:24 PDT 1993 -- Tim Mann
3158 * Sent WinBoard 3.0.pl7 to Torre on ICS
3160 * Added parser.h to hold the interface to parser.l
3162 * Upgraded COPYING file and copyright notices to GNU GPL version 2.
3164 3.0, patchlevel 6 -- Tue Aug 24 15:16:13 PDT 1993 -- Tim Mann
3166 * We no longer display intermediate positions or intermediate comments
3167 while loading a game file with -timeDelay 0 or loading an opening to
3168 start up a -matchMode game.
3170 * Loading an empty game from an xboard save file now gives a status
3171 message "No moves in game" instead of an error popup saying "Game not
3174 * Added comment.awk to distribution.
3176 3.0, patchlevel 5 -- Tue Aug 17 16:45:54 PDT 1993 -- Tim Mann
3178 * Bug fix: xboard would crash if it couldn't get all its colors; now
3179 it switches to monoMode instead. Also, xboard was trying to convert
3180 color resources even when using a b/w display. Reported by Larry
3183 * Bug fix: Declared fields of TimeMark as signed so that we get signed
3184 instead of unsigned arithmetic. SubtractTimeMarks was breaking on
3185 Alpha AXP (which has 64-bit longs) with old declarations. Reported by
3186 Michel van der List.
3188 * Bug fixes: Keyboard accelerators now work after EditComment window is
3189 popped down. Iconize keyboard accelerator now works even if xboard
3190 was started with -iconic flag and later deiconized.
3192 * Bug fix: The routine that tests whether a move is illegal because it
3193 would leave you in check was not handling e.p. captures properly.
3194 Reported by Patrick Surry.
3196 * Bug (?) fix: Was adding time to clocks at time control even when
3197 loading a game file. Actually it's not entirely clear how time
3198 controls should be dealt with when some moves are loaded from a file
3199 or clicked in with ForceMoves. For now ForceMoves mode does add the
3200 time (because it can be used to change moves during a live game), but
3201 LoadGame mode does not.
3203 * Updated usage message.
3205 * Previous attempted fix to matchMode had broken TwoMachines mode and
3206 generally needed more work. Also simplified command line interface to
3209 3.0, patchlevel 4 -- Thu Aug 5 14:17:18 PDT 1993 -- Tim Mann
3211 * Thanks again to the beta testers listed for 3.0 patchlevel 3, and also
3212 Desnogues, Steve Cariglia, Niklas Engsner, Mark Silver, and Roger Rowe.
3214 * Reorganized man page, splitting OPTIONS into subsections.
3216 * matchMode was very broken; fixed.
3218 * Changed convention for turning off command line options from --opt
3219 to -xopt, to be less inconsistent with GNU standards. Also changed
3220 the long command line options to take True/False arguments like
3221 resources; seems to make more sense this way.
3223 * Added AlwaysQueen option -- suppresses promotion dialog and always
3224 promotes to a queen if you move a pawn to the last rank. Has no
3225 effect on gnuchess (or your ICS opponents!) -- they can still
3228 * Subtracted an extra fudge term when determining how wide message and
3229 title widgets should be. This fixes a problem some beta testers had.
3230 Wish I knew why it's needed.
3232 * Bugfix in parser; symptom was that you couldn't do LoadGame after
3233 observing a game on ICS.
3235 * Bugfix in Forward; didn't work after game ended while Pause was turned on.
3237 * Removed bogus execute bits on .h files.
3239 * Use REMOTE_SHELL and TELNET_PROGRAM definitions.
3241 * MachineWhite and MachineBlack now work from TwoMachines mode.
3243 * Popping down an error message with the [ok] button was not turning off
3244 the errorUp flag, so the next move would cause xboard to try to pop it
3245 down again, resulting in a wild memory reference and sometimes a crash.
3247 3.0, patchlevel 3 -- Tue Aug 3 17:40:27 1993 -- Tim Mann
3249 * Thanks to my beta testers: Patrick Surry, Takuya Kojima, Robert J. Luoma,
3250 Chris L. Petroff, Richard K. Lloyd, Michel van der List, Craig Metz,
3251 Antoon Frehe, Simon Clift, Shelly, Eric Peterson, Christopher Mitchell,
3252 Martin Koch, Ed Hanway, Steve Booth, Udo, Ken Hobday, and Joseph Duhamel.
3254 * Improved error messages for trying to move the wrong color pieces or
3255 to move when it's not your turn.
3257 * Special code for monoMode on 1-bit displays now understands displays
3258 where 1=white and 0=black.
3260 * Declare getenv() if <stdlib.h> not included; avoids a compiler warning.
3262 * Documented borderXoffset and borderYoffset.
3264 * Added -titleInWindow option for use with X window managers that
3265 don't let us set the title in the window banner.
3267 * Fixed error message printing in WinBoard; system error messages no
3268 longer appear as numeric codes.
3270 * The error message popup is now non-modal; you don't have to press the
3271 [ok] button before you can do something else. In addition, the popup is
3272 positioned so that it doesn't cover up the board (too much), and making a
3273 move or otherwise clicking on the board pops it down. (Not implemented in
3276 * You can now call your opponent's flag in ICS mode by clicking on his
3279 * Fixed minor bugs in -flipView option and documented exactly how xboard
3280 decides which way to flip the view.
3282 3.0, patchlevel 2 -- Fri Jul 30 22:20:23 PDT 1993 -- Tim Mann
3284 * Added Autosave to Options menu. Would be better to have Save
3285 Options dialog as in WinBoard, but this was quick to do and gives the
3286 most-needed functionality.
3288 * Changed "Reload Game" on menu to "Reload Same Game".
3290 3.0, patchlevel 1 -- Thu Jul 8 21:22:59 PDT 1993 -- Tim Mann
3292 * Sent a copy of patchlevel 1 to Patrick Surry to beta-test.
3294 * Added -cmail option that sets appData.cmailMode. Currently a no-op.
3295 In the future this may set special modes for use by the cmail script
3296 for playing chess by email.
3298 * Added LoadNextGame, LoadPreviousGame, and ReloadGame to File menu.
3299 ReloadGame suggested by Patrick Surry.
3301 * Added -flipView command-line option. Suggested by Patrick Surry.
3303 * Fixed bugs in parser.l: (1) Pattern for "# xboard game file ..."
3304 needed to match to end of line. (2) Start of a new file was not matching
3305 the ^ start-of-line character. The fix for this is a kludge.
3307 * Made game counting code in LoadGame more robust, and made LoadGame
3308 able to detect the end of a saved partial game (by noticing the start
3309 of the next game) in game files created by XBoard itself. We don't
3310 try to find the start of the next game that way in other kinds of game
3311 files, because the only way I can think of to do that is to look for
3312 another move #1, and that technique gets too many false hits.
3314 * Fixed recently introduced bug in LoadGame when game starts with a
3317 3.0, patchlevel 0 -- Fri Jun 25 14:17:17 PDT 1993 -- Tim Mann
3319 * Changes in this patchlevel were too numerous to list. Larger ones are
3322 * Added a popup dialog to enter and edit comments. Inspired by some
3323 code from Patrick Surry. Changed the normal read-only comment popup
3326 * Added ICS init script feature from Karl Schwamb.
3328 * Added some ESIX fixes and OMIT_SOCKETS ifdef option, from Kayvan Sylvan.
3330 * Revamped code to allow use of flex instead of lex on parser.l.
3331 Using flex requires adding -DFLEX to defines in Imakefile.
3333 * Source code is split into front end (xboard.c), which knows about X
3334 and Unix, and back end (backend.c), which knows about chess, gnuchess,
3335 and the ICS. There is also a front end for Windows NT.
3337 * Boolean command line options now use "-foo" to turn on and "--foo"
3338 to turn off instead of "-foo true" and "-foo false". [Later -xfoo;
3341 * Added menu commands to control autoflag, bell, and coords options.
3343 * User interface has a new look: (1) Menu bar instead of array of
3344 buttons. A few very commonly used features have small buttons in
3345 addition to being on the menus. (2) Large font for clock. (3) Pop-up
