I created a release with a couple of compiles IpMan has done.

https://github.com/jhellis3/Stockfish/releases/tag/v2.0
IpMan also included a "general" version for older PCs:

If anybody needs a compile for certain version of Windows 32 bit or 64 bit - please let me know and I will try to help .

I have added one more very minor update, which includes the following:

1) Correct scoring support for 7 piece TBs

2) Put a few example positions in the readme for the inevitable question: why Crystal?

3) Retired razoring.... it was barely worth any Elo, (even tested better without it at LTC for me), severely restricted in application, and the only negative early pruning. Removing it cleaned up the code and is one less thing to worry about, which I am all for, so it is gone :).
Any binaries of this minor Update? (Apr. 9, 2020)

Crystal is intended for analysis, but could some testers include it in their rating lists ?

CCRL already tests SF derivatives Sugar, ShashChess, or even a problem-solving engine like Sting. It wouldn't be anything unusual to have Crystal compete.

I'd be curious about the results.

Crystal plays stunningly strong, when you see, that it's depth is 5-7 plies less than SF11! It's stronger than Komodo or Houdini.

Only familiar with this engine in its role as a kibitzer for the TCEC games, but it strikes me as essential for serious analysis. Has really shone in detecting draws long before even the 176 thread beast has a clue (TCEC has it running on 16 threads). Much appreciate & respect to its author/authors!

Thanks for the kind words. I don't really have the setup to provide high quality cross compiles...

But I wouldn't bother with the minor updates for now. I'm still actively working on it and SF dev is going at a rapid pace. Once things slow down a bit and I am confident I have everything I want in for the near future, I will see about contacting someone for some high quality builds and doing a v2.1 release.

I hope You have looked at Houdini 6 tactical mode source. It solves some tactics still faster than Crystal even being from 2017!
