+_Currently in prerelease. The below release notes will be condensed into a single entry on final release._
+
+_v2.2.0a1 (23 September 2021)_
+
+- 🌟 Added support for [musllinux](https://www.python.org/dev/peps/pep-0656/). Support for this new wheel format lets projects build wheels for Linux distributions that use [musl libc](https://musl.libc.org/), notably, [Alpine](https://alpinelinux.org/) Docker containers.
+
+  Musllinux builds are enabled by default. To disable them on your project, add `*-musllinux_*` to your [`CIBW_SKIP`/`skip`](https://cibuildwheel.readthedocs.io/en/stable/options/#build-skip)
+ option. (#768)
+- 🛠 Setting an empty string for the [`CIBW_*_IMAGE`](https://cibuildwheel.readthedocs.io/en/stable/options/#manylinux-image) option will now fallthrough to the config file or cibuildwheel's default, rather than causing an error. This makes the option easier to use in CI build matricies. (#829)

 This is a composite step that just runs cibuildwheel using pipx. You can set command-line options as `with:` parameters, and use `env:` as normal.
