fishnet v2.3.2
Changes:
- Perform all analysis in
UCI_Chess960mode (for lichess-org/lila#7582). - Update Official Stockfish (official-stockfish/Stockfish@1b325bf...0470bce).
fishnet v2.3.1
Bugfixes:
- More robust timeout handling, now with a sliding budget for multiple moves. Fixes timeout errors introduced in v2.3.0 due to increased volatility in move time, especially at startup on Windows.
Changes:
- Updated Official Stockfish (official-stockfish/Stockfish@ff4c222...1b325bf).
- Optimized
~/.fishnet-statswriting, keeping the file open indefinitely.
fishnet v2.3.0
New features:
- Stats are now stored locally in
~/.fishnet-statsand preserved across restarts.
Changes:
- Updated Stockfish development version (official-stockfish/Stockfish@0f3f5d8...ff4c222, includes new
HalfKAv2NNUE architecture). 15%-20% lower nps is expected. - Now using Fairy-Stockfish 13.1 (instead of Multi-Variant Stockfish) for chess variant analysis. Currently only using handcrafted evaluation.
- No longer providing
aarch64-unknown-linux-gnubuilds. Can still be compiled from source. - Changed fishnet build process to include compilation of Stockfish for various architectures. Previously, precompiled Stockfish builds were provided as binary blobs. The new approach is more flexible and transparent, but significantly increases build times.
fishnet v2.2.6
Changes:
- Will now select
bmi2builds on processors from the AMD Zen 3 family, for a small speedup. - Updated Stockfish: official-stockfish/Stockfish@3597f19...0f3f5d8.
