Version 1.3.1 (bugfix release)

[pkrisz99]

This is a small bugfix release addressing two issues:

• After adding support for non-power-of-2 transposition table sizes, the wrong part of the board hash got saved for each entry. This resulted in losing resiliency against hash collisions, corrupting parts of the search tree. The performance severely degraded as hash size, time control, and thread count increased.
• There was a move generation bug in FRC, where the engine allowed castling even if the king got in a check by a sliding piece on the backrank. Fortunately, positions like this are fairly rare in games.
