The version-numbers (180622 for example) of the engines are the date of the latest patch, which was included in the Stockfish sourcecode,
not the release-date of the engine-file. Especially the asmFish-engines are often released much later!!
Below you find a diagram of the progress of Stockfish in my tests since the end of 2018. And below that diagram, the older diagrams. You can save the diagrams (as a JPG-picture (in originial size)) on your PC with mouseclick (right button) and then choose "save image"...The Elo-ratings of older Stockfish dev-versions in the Ordo-calculation can be a little different to the Elo-"dots" in the diagram, because the results/games of new Stockfish dev-versions - when getting part of the Ordo-calculation - can change the Elo-ratings of the opponent engines and that can change the Elo-ratings of older Stockfish dev-versions (in the Ordo-calculation / ratinglist, but not in the diagram, where all Elo-"dots" are the rating of one Stockfish dev-version at the moment, when the testrun of that Stockfish dev-version was finished). Latest Website-News (2020/08/09): Testrun of Stockfish 200807 avx2 with "default"-Framework nnue-net 9931db908a9b (= sv200806_1802 net) is finished. +66 Elo to Stockfish 200731. +99 Elo to Stockfish 11. Mention, that in my NNUE-net quick tests, this net is -24 Elo weaker than the best nets sv200805_1056 and sv200805_0633. So, I will repeat this testrun with the same binary (Stockfish 200807 avx2) and the net sv200805_0633 (0633 has less losses and more draws vs. Stockfish 200717 than 1056, and I think, that, when playing against much weaker engines in my full 7000 games testrun, this a little more solid play will give slightly better results - but the difference should be very small).Let's see, if there is a measureable Elo-gain. I dont believe in +24 Elo, but hopefully around +10 Elo or so... Result on Tuesday.
