We have a new release: [Crystal 1.10.0 is released! - The Crystal Programming Language](https://crystal-lang.org/2023/10/09/1.10.0-released/)

While we have tested it against several known and sizeable projects, that doesn’t preclude the existence of regressions. If you find an issue, please check the [issue tracker](https://github.com/crystal-lang/crystal/issues?q=is%3Aissue+is%3Aopen+sort%3Aupdated-desc) and file a bug: it will be fixed in the following patch version.

The full changelog is available here: [Release 1.10.0 · crystal-lang/crystal · GitHub](https://github.com/crystal-lang/crystal/releases/tag/1.10.0)  
This release is a continuous improvement with some new features but no really big changes.

Builds are available on the supported platforms, check the [install page](https://crystal-lang.org/install) for details. That includes [docker images 🐋](https://hub.docker.com/r/crystallang/crystal/), [snapcraft](https://snapcraft.io/crystal), `.deb` and `.rpm` packages, Windows builds and the brew formula 🍺.

Happy Crystallizing!

The block unpacking improvements are very cool!

FYI, minor typo in the second “Changes” subheading:

> Breaking: `crystal spec` exists with failure when focused

should probably be

> Breaking: `crystal spec` exits with failure when focused
