Special thanks to:

  • _BigBoss_ for testing this build on 1.0.2
  • HotStuff2 for being superb QA for Caissa project
  • and everyone who contributed, but not mentioned above

This is for you Grandmasters. The game play feels sleek at higher difficulty levels. For those who think Caissa can really defend herself well. I can beat her at -4 9 out of 10 times and at -3 i can make it to the draw every other time. Month ago, I felt inadequate too :)


Exchange like crazy. She gets less wise with less pieces on the board.

Caissa 0.84b-alpha January 8,2008

  • skin and add-on support fixed for pieces
  • crash bug #66 addressed (thanks HotStuff2 for catching this)

This one is for Armadillo and Eurisko. Your turn gents :)

Caissa 0.84-alpha January 6,2008

  • Save on exit mode
  • fixed preference discrepancy for first time users
  • 8 bugs were addressed(2 crash bugs, 2 desync and other 4 were nonsense of a different kind)
  • Minor engine tuning.

There were many internal changes, that shouldn't affect your gameplay experience and will not have any visual effect for now, but it is foundation for many new things. They will fix some exotic bugs, like you can castle with rook that was moved and put back if you save/restore between move and castling.

IMPORTANT: This release will wipe out your saved game and preferences, due the the refactoring of the preference system. Not much to loose, but I warned you :)
