Maverick 0.60
http://www.chessprogramming.net/downloads/
Here are the changes:
+ Support for Chess960
+ Basic King safety
+ Fixed a problem with using the opening book with Arena
+ Fixed an obscure bug which could crash the engine after a stop command
+ Transferred source code to Github (https://github.com/stevemaughan/maverick.git)
+ Made a bazillion tweaks which may, or may not, help!
Based on self play the improvement in strength is about 50 ELO. I'm hoping this translates into at least +30 ELO in the real world.
