A little exception for a new program, which was only released for linux so far.
I started compiling first versions in July and now after the author isn't anonymous
anymore, I decided to compile the other versions too.
(except the most recent one, which now uses a SF nnue network, which doesn't comply with my rules)

(New) Black-Cat (or Black-Cat-Chess) versions 1.2a, 2.0, 2.1, 2.2 and 2.3 compiled by me, available at the usual place.

As reported by Graham, Clover 3.2.1 still crashed at CCRL Divison 2, so I recommend not using it . I will try fixing the crash errors as soon as possible, which is weird, cause in my testing I never got any crash... Sorry to all testers that tested 3.2 or 3.2.1.

Hmm, nevermind, it seems that it was an issue on Graham's side. Seems like 3.2.1 is safe and I recommend using it over 3.2
