Finally got glChess 0.9.0 out the door! So it's up there on the website as a source and .deb package.
I had to end up making a .deb package for PyGtkGLExt. Hopefully Debian/Ubuntu will take the work off my plate in the future!
So one big new features is good AI support - I have it working with four AIs and you can load and save games without the AIs getting confused. It turned out most AIs don't seem to have a save function so I just inform them on load what the previous moves were.
But there's no network support now. I plan to get it back in later.
