- Initial release


27th Aug 2003	Version 1.1

MSCP Engine changes

- Added halfmove tracking, so that MSCP will now call a draw on a game with
  50 consecutive moves without either a pawn move or a capture.
- Added a full history of moves, allowing the last move and last move SAN
  string for each side to be maintained, and rewound, on move undo.
- New "history" xboard command, and MSCP_EXEC_HISTORY equivalent, to print
  out the complete list of game moves since setup.  Output is in PGN format,
  for use with PGN save files.
- Reassigned tick callback period to instead be an opaque parameter passed
  back to a tick callback.
- Redesign of output buffering.  Originally, the buffer size and count of
  buffered characters was held in bytes 0 and 1 of the buffer.  Now, sizes
  and lengths are passed in and out of MSCP explicitly and separately.
- Improved error handling in FEN setup.  In particular, an invalid FEN will
  now not overwrite or alter the current board setup, and is properly ignored.
- FEN setup now reads in the ply and halfmoves, previously ignored or
  defaulted.
- Moved from MSCP's pseudo-random number generator to Inform's.  This will
  improve the randomness of openings played, as Inform's random numbers are
  seeded by system time, or other unpredictable value, on interpreter start.
- Fixed a core MSCP bug that caused loss of en passant data, and another to
  do with incorrect FEN imports of en passant target square.
- Fixed status output for correct en passant target square at all times, not
  just when an en passant capture is possible.
- Assorted small bugfixes, minor speed improvements, and readability
  improvements.

Glkboard changes

- Control panel buttons are now anti-aliased.
- Smarter graphics update used to improve GUI responsiveness.  In early
  versions, the complete GUI was redrawn on each GUI event; now, only the
  GUI elements that have changed are redrawn (with a couple of minor
  exceptions), leading to much snappier GUI response to mouse presses.
- Image dimensions are now cached in the program, to save repetitive image
  queries.
- Messages added for game draw, game saving and loading, and loading failure.
- Added halfmove tracking for calling a draw on games that might otherwise
  be endless.
- Implemented full PGN save/load format for saved games.  PGN game data can
  now be both exported to and imported from Xboard and other chess programs
  that use or understand PGN format.  As a result, saving and loading are
  somewhat slower operations, but their data format is much more portable.
- Added some limited error reporting on trying to load invalid PGN data.
- Assorted readabilty changes, internal adjustments, and speedups.
