This update should let Integral breach into the top 15, maybe even top 10 if it scales well enough. It's genuinely crazy seeing where this project is now.
Notable things in this update are:
- Support for Multi-PV
- Many search improvements and an SPSA tune
- Bug fixes for wrong scores returned when using Syzygy tablebases
And of course, special thanks to everyone in my OpenBench instance and the kind, helpful people in the Stockfish discord.
