Stockfish 16 Released +47 Elo gain over Stockfish 15 (Single threaded, UHO)
https://github.com/official-stockfish/Stockfish/releases/tag/sf_16 link to the binary's
If you use ChessBase on a MacBook through Parallels, there's an issue where people have posted Apple Silicon compiles for Windows: https://github.com/official-stockfish/Stockfish/issues/4241
no realistic time controls, especially since stockish is mostly optimized for 60+0.6 and beyond. Anything lower you are basically playing out of sf optimum since a lot of things actually perform well at 60+0.6 but bad at 10+0.1, like this one - https://github.com/official-stockfish/Stockfish/commit/84b1940fcae95bb0a641dda9e85cb96f8c21cd22 . So sf at smth like 1 second/game or maybe lower is somewhere near supergm level but it's pretty meaningless since it more or less bugs out there because of complete missoptimization of it search (and net also, for this TCs I would pick really really small net compared to master one).
There isn't an Apple Silicon binary in the official releases as of now, you can either use the x86-64-modern version for a slightly degraded performance, or manually compile from source (https://github.com/official-stockfish/Stockfish/wiki/Compiling-from-source).

Stockfish 16 is ready!
Progress can be found here https://github.com/official-stockfish/Stockfish/wiki/Regression-Tests At 1 thread it has gained +18.3 elo on a balanced book, and +47.03 on UHO (unbalanced) book as well as +39.4 elo for FRC and +65.56 for DFRC. At 8 threads it has gained +14.33 elo on a balanced book and +49.46 on UHO (unbalanced book). Also testing was done on 8 threads with 180+1.8 (this is considered very long time control for fishtest standards) and progress was +9.45 on balanced book and +49.65 on UHO.

Stockfish 15 is now available
You mean this? These are not opening books, though they're called "books". They're PGNs with starting positions, usually a couple of moves into the game, that are used for statistical tests as having engines play from the regular starting position does not sweep the space of realistic game positions very well.
- Stockfish 15 is ready!
- Today, we have the pleasure to announce Stockfish 14.1
