- Update to 15.1:
  * Elo gain and competition results:
    With this release, version 5 of the NNUE neural net architecture
    has been introduced, and the training data has been extended to
    include Fischer random chess (FRC) positions. As a result, Elo
    gains are largest for FRC, reaching up to 50 Elo for doubly
    randomized FRC (DFRC). More importantly, also for standard chess
    this release progressed and will win two times more game pairs than
    it loses against Stockfish 15. 
  * New evaluation:
    This release also introduces a new convention for the evaluation
    that is reported by search. 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.
- Refresh:
  * date.patch
  * stockfish-remove-net.patch
- Remove nn-6877cd24400e.nnue
- Add nn-ad9b42354671.nnue
- Keep man page and stockfish-interface.txt but remove URL from
  Source. Because not available anymore.
