Crystal 3.0

[jhellis3]

Decided it was an appropriate time for release.

Changes since 2.0:
Various bugfixes mostly due to members of the community pointing out usage issues to me.
Some minor eval smoothing (simple linear interpolation between previous value).
Introduction of NNUE. For now, NNUE is either on or off, there is no hybrid method involved or available.

Hoping someone can post the various binaries as well.

Maybe you need to be registered at Outskirts, if it's a link from there?

The problem must be somewhere else, I downloaded and I'm not.

You are right. In my case whitelisting the site with Malwarebytes did the trick. I wish the error message would have been more helpful, but oh well.
Thank you, and thanks again to Joseph for this great engine.
