New J.A Compiles

It's also one of the reasons why I appreciate CCRL. They only test official releases. If we tracked all the development versions, there would be thousands. It's already bordering on absurd....

I used to be a big fan of SPCC, but now that his Top15 has a multitude of development versions I pretty much ignore it now.

There is a point here, but the thing is that some of those dev versions participate in the strongest computer chess tournament TCEC, which I think gives them some credit to be valid versions. Also unfortunately some of those top engines do not do official releases for months and months. (if not years, like Rubichess)

I understand your point of view. But please mention, in the 2 big engine tournaments TCEC and CCC (on chesscom), the engines play with latest dev versions and some engines have very old official releases.
Example: Integral. Latest official release: V7 from February,14, 2025. But 76 patches (!) applied since then on github.
Does anybody really want to have Integral 7 in a live-engine-ratinglist, when a much better and newer version plays in the big tournaments?
I decided, the answer for me is NO.
And because my Ratinglist is so small (Top15 only), it is possibly for me, to do more testruns of the top engines, so I can provide results of latest dev versions of the engines.
And I always make sure, that all dev-versions, I use for testing, can be downloaded by everyone. If the new dev version was not taken from official github, I always provide the download-link of the engine binary, when I publish the results of this engine.

After testing Stockfish since more than a decade now, the difference between dev-versions and release-versions are not so important for me anymore. Stockfish provides lots and lots of dev versions until they reach a amout of progress (+100 normailzed Elo), and then this dev version is called official release. For me, not very exciting. For me, the progress of the engines is interesting. And you see the progress, when testing the dev versions. The more testruns, the better. In our times of free and open software, official releases are just one of a lots of dev versions.

If a dev version replaces an official release in my UHO-Top15 Ratinglist, the official release version can still be found in my full UHO ratinglist:
https://www.sp-cc.de/files/uho_full_list.txt

What I could do is: Making a second UHO-Top15 Ratinglist, using only official release versions. And providing both ratinglists. But with the additional gamepair-lists, this would mean 4 lists instead of 2. Wouldnt that be very confusing?
