Release 1.2 of ExaChess adds several new features and fixes a number of bugs.
The new features include a Copy Position command to copy the current board
position as a picture, and a facility to search a database for games between players
over a particular Elo rating.
All significant changes are detailed in the section Change History below.
New features
Documentation on the above new features is not available in the ExaChess Help file, and is given here:
Copy Position (Edit Menu)
This pops up a submenu allowing you to choose the format of the information that gets copied to the clipboard.
• As Game. This copies the position as a game with a setup position, either Text or PGN according to the setting of General Preferences / Clipboard format is PGN. Positions copied in this manner can be pasted into new Game windows.
• As Picture. This copies the position as a diagram of a chessboard formatted as a Mac picture. The diagram is a square text block using characters of the current printing font. You need to install a chess font and enable it in Chess Preferences for the board to appear as a chessboard. Use this format to paste diagrams into drawing programs.
• As Text Board. This copies the position as a diagram of a chessboard formatted as styled text. The diagram is a square text block using characters of the current printing font (see above). You need to install a chess font and enable it in Chess Preferences for the board to appear as a chessboard. Use this format to paste diagrams into text documents. Note that if the application into whose document you are pasting doesn't support Mac styled text, you may need to reapply your chess font to the pasted text block in order for the board to appear as a chessboard.
Minimum Elo Searches
To search for games by minimum Elo, enter a minimum Elo value in place of a players name when entering database search criteria:
2400 All games by players rated 2400 or more
kasp-2600 All games by Kasparov as White against an opponent rated 2600 or more
Elo ratings are taken from the values stored in the games themselves, or if these are not available, by looking up the name in the Masters file in the ExaChess Tools folder.
Upgrading
To upgrade from ExaChess 1.0 or ExaChess Lite 1.0, either move your databases
into the new ExaChess Games folder, or copy the new ExaChess application to
your existing ExaChess folder and the new ExaChess Help and the Opening Key,
Opening Names, and Opening Extn files to your existing Tools folder. Note also that
the King's Indian Samisch database is new, and for ExaChess Pro users there is now
a Utilities folder within the Tools folder.
The index format is unchanged, so you do not need to reindex your databases. However,
the new Opening Key file contains many additional lines and is much better at correctly
classifying openings which involve transpositions. You will need to reindex in order to
pick up such reclassifications.
To upgrade from ExaChess 1.1 or ExaChess Lite 1.1, simply replace the ExaChess
application with the new version, and install the Masters file into your ExaChess Tools
folder.
Change History
Changes in 1.2 with respect to 1.1.3
GAMES
√ Added Copy Position submenu to copy the position in the front game window in
one of 3 formats: as Game (Text or PGN game with setup position), as PICT
using current printing font, and as a styled text board (same as PICT but
using styled text).
√ Opening Tree display size is now saved with Set Window Defaults for game window
√ Max piece size increased from 48 pt to 72 pt (but larger Staunton pieces will look
ragged)
√ Increased hash to 64 bits (but longer value not yet used in database indexes)
√ Fixed bug: Font and size can now be adjusted in Text View. Changes in one view
update the other view.
DATABASES
√ Can now search for all games played by players with an Elo above a specified value.
Just enter the Elo in the Players field. If a file Masters is present in the
Tools folder, missing Elo values are found by looking up the name in the Masters
file.
√ Fixed bug: Fixed nasty problem of 'Tried to get non-existent resource' error messages
which would show up after several rounds of changes to database.
√ Fixed bug: PGN files are now parsed in English even when Language is non-English.
This fixes problems seen by some users of PGN games being parsed for the first
one or two moves only with the rest of the game as a comment.
√ Fixed bug: Given names are now indexed in full (rather than first initial only)
so that Database Prefs / NameFormat = 'Surname,Given' works as advertized
√ Fixed bug: Error reporting during failed database operations such as reindexing
is more reliable, e.g. out of memory errors while building Opening Tree index.
√ Fixed bug: There's now an error message (rather than a crash) if a database whose
games appear in a Find result is renamed or moved, and an attempt is made to open
one of those games.
√ Fixed bug [Lite, 1.1]. Databases with more than 256/128 deleted games can again
be opened.
√ Fixed bug: ShowDuplicates, ShowDuplicatesAll now checked in menu
Changes in 1.1.3 with respect to 1.1.2
DATABASES
√ Reduced memory requirements further when opening very large databases.
A 1-million game database can often be opened within ExaChess's default
memory allocation of 2.4 MB.
√ Fixed bug: No longer crash if ExaChess runs out of memory while opening
a database window
√ Fixed bug: An initial notes no longer propagates to every move that precedes
a move with variations when saving games into ExaChess databases
Changes in 1.1.2 with respect to 1.1.1
GENERAL

√ More error dialogs are now movable modal
√ Libraries now use HOpenDF instead of HOpen under System 7 or later
GAMES
√ Opening Tree pane is resizable (but new size not yet saved)
√ Opening Tree view now shows percentage games < 1% as 0.x%
√ Fixed bug: Correct variation is now consistently highlighted
in Show Game Text view.
√ Fixed bug: New unmodified game window is no longer marked as 'dirty'
so Confirm Close dialog isn't forced when new window is closed
√ Fixed bug: Consecutive PGN nags (e.g. $4 $19 meaning ?? -+) are
now handled
DATABASES
√ Fixed bug: Find no longer trashes the display of any already open databases
which it searches (which could lead to a crash).
√ Fixed bug: Recovery of ExaChess-format databases much less likely to hang.
√ Fixed bug: No longer crash on converting heavily annotated games to CB-format
√ Fixed bug: Only the first 300K games can now contribute to Opening Tree index

GAMES
√ Fixed bug: Balloon help for the game window toolbar was still as for
the 1.0 icons, not the 1.1 changes
DATABASES

again and Recovering shows correct games/s value.
Changes in 1.1 with respect to 1.0
GENERAL

where System Help menu has been removed by an extension such as CPU.
GAMES
√ Rearranged toolbar
√ Added Go To Start and Go To End menu commands and toolbar buttons
√ Show Captured Pieces and Show Game Text settings now saved in Prefs
√ Show Game Text is greatly improved. Last move played is automatically
highlighted as you play through the game. Clicking on a move positions
the game at that move (use option-click to set insertion point).
Arrow keys navigate through the game (use option-arrow key to move
the insertion point). Changes are applied after return (use option-
return to type actual return) or space (if Space enters move is
set in prefs); no need to switch back. Game header is separated from
moves.
√ Can now enter a date range for correspondence games, in the notation
1995-97 or 1999-01; end year must be 1 to 5 years from start year;
can't have month or day present. Supported in Text, PGN and
ExaChess databases, but not ChessBase or NICBase. (PGN databases use
a newly invented tag 'EndYear').
√ Removed feature whereby an immediate correction (go back then make a
different move) deletes the corrected move.
√ An optional semicolon is now allowed before keywords in title
√ Short variations are now shown in full in input box, longer ones are
shown with first move followed by an ellipsis
√ Added Swedish as a supported notation language

result and number of moves
√ Fixed bug: Scrollbar and input field now properly deactivated on Suspend event
√ Fixed bug: Can now set font, size of text in game window

with a '-' move, e.g. 1 P-K4 P-KR4 2 Q-R5 (meaning QxP) no longer allowed
√ Fixed bug: Set Main Line now updates move list to bold
√ Fixed bug: Figurines now display correctly for fonts which have a non-zero
descent (such as Linares)
DATABASE
√ Added progress bar to show progress of slow database operations
√ Changed NameMatch criteria to handle given names, including incorrectly
separated names
√ Added support for very large databases. Previously database size was limited
by the 16M limit on the size of a Mac file's resource fork. Now databases
with more than 105K games use up to two additional index files (.idx and
.idp) to hold portions of the index.
√ Major reduction in memory requirements for opening large database: reduced
from around 1 MB per 100K games to perhaps 250K per 100K games.

databases with minor imperfections in the data (such as duplicated tags,
blank lines after each line etc.).

√ Fixed bug: Entering moves on the Position search dialog board no longer
sets title to Untitled and brings up Confirm Save dialog on exit
√ Fixed bug: Compacting a database no longer changes its format to Exa
FIND
√ Option-Clear Search now clears results without clearing criteria (useful
for keeping criteria but not doing Follow on search)
√ Follow on search only happens if previous search actually found some games
√ Cancelling a search now works more reliably
OPENING TREE
√ Added Opening Tree index which allows game window to instantly show all next
moves and their stats from the database for any opening position
