- 🐛 Fix bug in the GitHub Action step causing a syntax error (895)

_26 October 2021_

- 🛠 Added a `config-file` option on the GitHub Action to specify something other than pyproject.toml in your GitHub Workflow file. (883)
- 🐛 Fix missing resources in sdist and released wheel on PyPI. We've also made some internal changes to our release processes to make them more reliable. (893, 894)

_22 October 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. (#768)

Musllinux builds are enabled by default. If you're not ready to build musllinux, add `*-musllinux_*` to your [`CIBW_SKIP`/`skip`](https://cibuildwheel.pypa.io/en/stable/options/#build-skip) option. Or, you might have to make some changes to your options - to simplify that process, you can use...

- 🌟 TOML option overrides! This provides much greater flexibility in configuration via pyproject.toml. (854)

You can now set build options for any subset of your builds using a match pattern. So, for example, you can customise CPython 3.8 builds with an override on `cp38-*` or musllinux builds by selecting `*musllinux*`. Check out [the docs](https://cibuildwheel.pypa.io/en/latest/options/#overrides) for more info on the specifics.

- 🛠 Added support for building PyPy wheels on macOS 11 CI runners. (875)

- 🛠 Setting an empty string for the [`CIBW_*_IMAGE`](https://cibuildwheel.pypa.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 matrices. (829)

- 🛠 Support for TOML 1.0 when reading config files, via the `tomli` package. (876)

^{Note: This version is not available on PyPI due to some missing resources in the release files. Please use a later version instead.}

_6 October 2021_

- 🛠 Updated CPython 3.10 to the 3.10.0 final release

_14 September 2021_

- 🛠 Updated CPython 3.10 to 3.10.0rc2
- 📚 Multiple docs updates
- 🐛 Improved warnings when built binaries are bundled into the container on Linux. (807)

_7 August 2021_

- ✨ Corresponding with the release of CPython 3.10.0rc1, which is ABI stable, cibuildwheel now builds CPython 3.10 by default - without the CIBW_PRERELEASE_PYTHONS flag.

^{Note: v2.1.0 was a bad release, it was yanked from PyPI.}
