About a month ago, Crystal's multi-threading moved out of preview. I'm a little late with the blog post, but figured I'd share it here in case someone is interested in the language.

To those unfamiliar with Crystal, it's basically an AoT-compiled language with a syntax that's inspired by Ruby but with static type safety.

It doesn't have a big org behind it, so Manas Tech still working on the language and shipping enhancements is quite amazing imo. I will add that while it's used by Kagi and Lavinmq, I don't think either company has the same resources to pour into Crystal as Jane Street does with OCaml.

I haven't really had the chance to play around with the changes. So, got no clue on what the experience is like.
