Stockfish 2.2.2
Released 1 year ago on January 14, 2012
The 64-bit Windows compiles are built with GCC instead of Intel, so there is a 5-6% speed increase. Very few code changes: it should be a bit faster and a bug is fixed where Stockfish in some (rare) positions erroneously moves immediately without thinking.
Stockfish’s new signature is: 5447426
