What's new in Stockfish Chess 2.3.7
Feb 28, 2024
- Updates engine to Stockfish 16.1, which features:
- Updated neural network architecture: The neural network architecture has undergone two updates and is currently in its 8th version.
- Removal of handcrafted evaluation (HCE): This release marks the removal of the traditional handcrafted evaluation and the transition to a fully neural network-based approach.
- Dual NNUE: For the first time, Stockfish includes a secondary neural network, used to quickly evaluate positions that are easily decided.
New in Stockfish Chess 2.3.6 (Oct 29, 2023)
- Updates the engine to the October 27, 2023 build (Stockfish dev-20231027-347d613b). Includes the following enhancements:
- Quality of chess play: Stockfish continues to demonstrate its ability to discover superior moves with remarkable speed. In self-play against Stockfish 15, this new release gains up to 50 Elo and wins up to 12 times more game pairs than it loses.
- Neural network: This updated version of Stockfish introduces several enhancements, including an upgraded neural net architecture (SFNNv6), improved implementation, and refined parameterization
- New evaluation: An evaluation of +1 is now no longer tied to the value of one pawn, but to the likelihood of winning the game. With a +1 evaluation, Stockfish has now a 50% chance of winning the game against an equally strong opponent. This convention scales down evaluations a bit compared to Stockfish 15 and allows for consistent evaluations in the future.
