New features: http://triplehappy.wordpress.com/2011/09/06/new-features/
Main window width can be usefully widened.
Main window size and position are preserved across sessions.
Small chess board graphics option.
Chess notation can now use any letters from the Roman alphabet, not just the English language convention.
Custom UCI engine parameters can be specified (e.g. specify reduced Elo strength for training games).
Changes to game dialog column widths are preserved, not only within sessions but across sessions.
Pasted text to an empty move window is automatically promoted to chess moves if possible.
Stopping kibitz does not immediately clear the kibitz window.
Optionally, skip game selection menu if there is only one game in .pgn file.
Optionally, do not use italics for subvariation display.
Null move “–” (unofficial .pgn extension, useful for describing threats) supported when reading from .pgn files.
Keyboard Delete ^C, ^X, ^V in game selection dialog.
I have also fixed a minor slew of bugs. Emphasis on minor. The (first) beta version met my goal of being a lot less buggy than the alpha version. What the heck, the list is short enough to report it here. These are bugs present in the first beta version that should not be present in the updated beta version;
Status line doesn’t appear at start up.
Moves window doesn’t follow mouse wheel movement.
Delete key shortcut not mentioned in Edit menu.
Editing games unnecessarily spawns a duplicate game.
Undo sometimes repositions incorrectly, for example the last undo unnecessarily takes us back to the home position.
Promoting comment to variation properly supports continuations (as well as variations), but the continuation case should only apply at the end of a variation. Continuations in the middle of a variation cause problems instead of failing gracefully.
Promoting comment to variation only works within the first of a series of alternative variations.
Demoting variation to comment fails (badly) in the case that the whole main variation is demoted.
Green book moves window takes on a “muddy” appearance if rewritten multiple times in (some?) Windows 7 systems. (This has been a problem for a long time, I’ve finally found a work around – no idea what the underlying issue is).
