The new major release of Stockfish is announced today by the Stockfish team.
In tests against Stockfish 16, this release brings an Elo gain of up to 46 points and wins up to 4.5 times more game pairs than it loses.
In practice, high-quality moves are now found in less time, with a user upgrading from Stockfish 14 being able to analyze games at least 6 times faster with Stockfish 17 while maintaining roughly the same quality.
During this development period, Stockfish won its 9th consecutive first place in the main league of the Top Chess Engine Championship (TCEC), and the 24th consecutive first place in the main events (bullet, blitz, and rapid) of the Computer Chess Championship (CCC).
