AWESOME!

The new download table is super nice, many people asked for arm linux downloads. Thank you!

One minor note: the pre-built binary tarball, at least for Linux x86_64, has a slightly older version of nimble - v0.20.1. Latest is v0.22.1.

So you may want to update nimble after installing this nim patch.

Wow, thank you for another new version. This is fantastic. I especially like the multi-threaded fix for malloc. That has been a problem in the past, and I had to use malloc, and it always felt not great. Hopefully, this problem is now behind us. And thank you for the ARM builds as well. Those have come up. It is cool to see this project moving an doing. So many bug fixes, so many things are just getting repaired. It's great. Thank you for everyone who put in the hard work.

The shipping of the older Nimble version was done on purpose, as we had some problems with Nimble v0.22.x.

But, as you said, you can update Nimble manually. Both now and generally, whenever there is a new Nimble release. You don't need to wait for a new Nim release to update Nimble.

Docker Hub images have been updated: https://hub.docker.com/repository/docker/nimlang/nim/tags

BTW we're very close to making the Nim Docker Hub images official. I've just reimplemented the entire image generation routine to fit the official guidelines. The images are now build a lot faster, so we can archive docker-images-regular repository. And dhbp package is no longer necessary.

I plan to support Ubuntu-based images for 1.6.0—2.2.8+ Nim versions. Alpine and other flavors may be added later if there is demand for those.

Hopefully, this gets approved: https://github.com/docker-library/official-images/pull/19453

Thanks for the release guys!

Note, some of the Nim binaries from previous versions appear to be missing (or incorrect) on nim-lang.org. For example: https://nim-lang.org/download/nim-2.2.6-macosx_x64.tar.xz

Thanks for bringing this up. I faced missing binaries for 2.2.6 when an automated Docker Hub image job failed. Linux_arm64 was missing.

For anyone upgrading to 2.2.8 and using refc, the release is broken and you should revert to 2.2.4.

For anyone using 2.2.6, async/closure iterators are broken (for both refc and orc) and you should also revert to 2.2.4 if you use these features:
