This is Stockfish 2.1.1
Builds for Windows/Linux & Android.
Available from Jim's site:
http://jimablett.hostwebs.com/& soon from official site :
http://www.stockfishchess.com/This is a maintenance release to fix book reading
issue reported by some user, as an added benefit Jim's build should be
now a little faster on Intel CPU (4% on 64 bits and almost 6% on 32
bits).
This is a non functional change release so there is no need to retest
Stockfish for people that has already done, for people still to test
we suggest to use this one because should be a bit faster on Intel
hardware.
