v.0.5.0:

Improvements

In this release, an evaluation tuner is added to the engine. All evaluation parameters have been tuned with it using the training positions from the Zurichess dataset quiet-labeled.v7.

Additional evaluation parameters

Pawn structure: passed, isolated, backward and doubled pawns

Mobility

Bishop pair

Search

Improve root move ordering: whenever a new best move is found, it is moved to the front of the move list

Use multiple TT entries for move ordering (if the bucket contains multiple entries with different moves for the given position)

Add aspiration windows

Include non-capturing queen promotions in quiescence search

Add countermove heuristic

Stop search after depth 1 if there is only one legal move (only if the option wtime/btime is used)

Bugfix

Use all/both killer moves (previously, only one move was used)

Match against previous version
