Release Notes: This version includes an improved in-game interface, 7x7 Tic Tac Toe boards, and many more optimizations.
Release Notes: A rewritten pthreads engine (for better speedup with multiple threads, if run on a multi-processor machine) and an improved scoring system (with 5x5 and 6x6 tic tac toe games, the actual scores will be shown, not just the difference in scores).
Release Notes: This release changes the name to Ultra Tic Tac Toe, adds Connect 4, and makes some changes to the Board struct (for connect4).
Release Notes: The code was switched from C++ to C. A code cleanup was done. Minor optimizations were made.
Release Notes: A fix for the move-making algorithm (in version 0.9.0 the computer was losing a lot of games), lots of optimizations, and a switch to using autoconf.
