Subject: Stockfish 15.1 Released. Mon Dec 05, 2022 11:34 am
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. Stockfish continues to win in a dominating way all chess engine tournaments, including the TCEC Superfinal, Cup, FRC, DFRC, and Swiss as well as the CCC Bullet, Blitz, and Rapid events.

I am looking at the discussion topic from the chief developer Vondele from July last year. Yes, it is not yet 2½ years. But that was of course a quantum leap. People get spoiled Vondele explains it in the graph as mostly speed gain. You see less Elo the higher the time control (I assume), because speed does not matter much there. Holes do. That there was still much gain after that is well more speed up too but with newer architecture speed went down again in the run up to Stockfish 14 (I'm just reading that graph now, I don't know much else about it).
For chess, the NNUE also meant, Uly wrote about this a bit once, more openings became playable. That is a huge benefit too. (Less holes in chess knowledge).
