It's not a lot stronger, In my tests when compared to 2.8 it's +15 Elo standard and +30 Elo FRC.
In my FRC testing I measured +11 Elo so about the same as what you expect for standard chess. Thanks for the new release !

Thanks for the quick test! Around +10 Elo in both standard and FRC compared to 2.83 is what I'd expect. 2.83 to 2.8 I guess +20 Elo FRC, but just +5 Elo standard, as 2.8 -> 2.83 was primarily additional FRC training.

Jonathan,

The sse version does not work on my system, although all the previous versions still do.

I found a spot in the code where I was optimizing AVX2 code and forgot to make an SSE2 version. I fixed this and updated the slow64-sse.exe in the 2.9 zip on my webpage, hopefully it will work now.
