New Features 1.30
This is the 1.30 release of Raven Chess Engine
The only change is that I have fixed a bug with global variables which caused a major issue with move generation, causing Raven to not generate any double pawn push moves. This is now fixed and Raven can now play double pawn push moves.
This has led to an increase of approximately 300 Elo in self-play.
