1 Shogi Variants - Version History
2 --------------------------------
4 Linux gcc port (12 August '14)
6 - The source code was hand-converted to C.
7 - The GTK GUI code was extracted from XBoard, and cleansed of all
9 - Dialog and menu definitions were written to mimic the ShogiVar UI.
10 - Primary event handlers were written to mimic Visual-Basic events.
12 Version 1.55a (of 14 May '98) -
14 - Fixed the problem of the program occasionally incorrectly identifying
15 'Check' as 'Checkmate'.
17 - Corrected the problem of a player being able to leave their King in
18 check if giving check themselves.
20 - Fixed the move of the White Tiger on the Dai-Dai Shogi piece help screen.
23 Version 1.55 (of 30 April '98)
27 - Added the capacity to replay moves that have been previously taken back.
29 - The code for taking back moves has been completely rewritten and improved,
30 and a further user option for taking back moves has been added.
32 - The player can now toggle the moves of a game forward and backwards using the
33 TAB and BACKSPACE keys, or jump straight to the first or last move by pressing
34 SHIFT+DEL or SHIFT+INS.
36 - An option has been added to display the influence and threats of all pieces and
37 keep the influence map on screen until a key or mouse button is pressed. This option
38 is activated by the tilde '~' key.
40 - Fixed some problems with the configuration settings of loaded games.
44 Version 1.54 (of 23 April '98)
48 - Fixed a number of bugs that occurred only when the 'Show Legal Move'
49 option was set to off. These included the fact that the computer did
50 not correctly detect check and checkmate, errors in the move of the
51 Emperor and in application of the Lion protection rules in Chu Shogi.
52 (Thanks again to Rikard Nordgren for the report)
54 - Continuing problems with the computer occasionally leaving its King in
55 check have now been totally cured. (The earlier fix in version 1.53 only
56 reduced the incidence of the problem).
60 Version 1.53 (of 19 April '98)
64 - The bug that allowed a player to move a King next to the
65 opponent's King has been fixed. (This move is now only possible
66 if a player has more than one King-type piece)
68 - The speed of the flashing of the last moved piece is not now
69 dependent upon CPU speed (ie: the piece will now flash at the
70 same speed on a 486 as on a Pentium II)
72 - A bug that caused the computer player to occasionally ignore the
73 fact that its King was in check has been fixed
75 - There have been a number of changes to the AI. The most significant
76 of which are that the computer will generally promote a piece even
77 if it considers that it will be immediately lost, and it should now
78 be less likely to make some of the foolhardy attacking moves it made
79 at the higher playing level in version 1.52
81 - The kanji (Japanese characters) of the 'Horned Falcon' and 'Soaring
82 Eagle' on the Tai Help Screen are now the right way around.
83 (Thanks to Rikard Nordgren for reporting this problem)
85 - It is now possible to effectively pass a turn with a Lion powered
86 piece by double-clicking on it. (Thanks to Rikard for reporting this
89 - The name of the executable file has been changed to "ShogiVar.exe".
90 This name will be retained for future versions to assist with
94 Version 1.52 (of 13 April '98)
98 - Full implementation of the move of the 'Emperor' in Tai Shogi and
101 - The addition of a computer opponent for the Tai and Maka-Dai-Dai
102 variants (leaving Tenjiku Shogi as the only variant that does not
103 support a computer opponent)
105 - Fixed a bug in Dai-Dai Shogi that occasionally caused the computer
106 player's pieces to promote inappropriately.
108 - Added an option that makes a moving piece flash for several seconds
109 after the computer has made a move (to assist the beginner in following
110 the game) - Thanks to John Bailey for the suggestion.
112 - Pressing the space bar during a game at any stage will also now highlight
113 the last moved piece.
115 - Fixed a bug in the AI for Shogi that hindered the development of the
118 - Increased the randomness of the computer's moves (to produce more variation
119 in the game of the computer opponent).
121 - Improved the AI when dealing with multiple exchanges in the bigger games.
123 - Various other small bug fixes and changes.
126 Version 1.51 (of 27 March '98)
128 Fixed a significant problem with the AI in the 25 March release that caused
129 the computer to make unfavourable exchanges of pieces in the higher difficulty
133 Version 1.5 (of 25 March '98)
137 - The addition of two new variants
138 - Christian Freeling's Yari Shogi &
139 - Judkin's Shogi (also known as Mini-shogi Plus)
141 - Increases in the speed of the computer opponent at its basic level
142 by 3 to 8 times (depending on variant)
144 - The addition of a higher level of computer opponent (this
145 level is only partially developed and will be enhanced in future
148 - The program now stops the game on checkmate (rather than requiring

164 Oliphant for the bug report)
166 - Fixed the move of the White Tiger on the Tai Help Screen (ditto)
168 - Corrected a minor problem with the implementation of the special
169 Lion capture rules in Chu and fully automated the validation checks
170 for Lion moves in this variant (However, the restriction on not being
171 able to capture a Lion on a second square if the first square is a Pawn
172 or Go-Between has not yet been implemented).
174 - Added a computer opponent for Chu Shogi, Dai Shogi and Dai-Dai Shogi

219 The changes included:
221 - Program now recognises 'Check'. (Finally!)

261 - Made a number of small cosmetic changes to the graphics.
263 - Finally dropped the label "Beta". (Not because there are no more

265 for too long to get away with using that particular excuse
266 for its shortcomings)
269 Version 1.3 Introduced the variants Whale Shogi and Micro/Poppy Shogi, and
270 fixed several minor bugs (such as correcting the move of the Heavenly
271 Tetrarchs in Tenjiku, and improving the Take Back Move routines).
272 This Version also included provision for saving board positions as text.
274 Version 1.2.1a fixed a couple of minor bugs. Most notably problems with
