SFNNv9.5.3_240420 released...

Update 240420 for Windows: Full updated to SF master and, more important, Mediumnet threshold changed to 1200. Old value of 300 is completely off! Pre-release
Both Windows versions of SFNNv9.5.3_240420 are released now with new default parameter for Mediumnet threshold of 1200. Old value of 300 was just a (dumb and wrong ) guess and completely off... For both Windows engines I got warnings from the stupid MS Defender. Just ignore it (like I do since the 10th false positive) or test it on Virus Total.
Use 1200 in SFNNv9.5.3_240410 or even make selfplay tests with different values to find a good MnTh parameter (to find the optimal one takes 10000s of games). Anyway, the optimal value of Mediumnet threshold (MnTh) depends (not that much on the same OS) on hardware and also on TC. Both dependencies could be minimized by empirical formulas, however 100000s of games are needed. Thus MnTh in the moment is an uci parameter.
However, with one(!) good MnTh value Stockfish dev can be easily beaten at STC and LTC. Here are the three tests with MnTh=1200 on my mini PC with Celeron N5095 (modern builds):
