This is the final "HCE" version of Integral. Notable things in this update are:

  • Multiple search improvements.
  • Self-play data generation system.
  • New evaluation dataset of 40 million positions (combined from lichess-big3-resolved, Ethereal, and self-generated data).
  • Pawn-relative piece square tables.
