pypa/cibuildwheel v2.2.0a1

on GitHub

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. Support for this new wheel format lets projects build wheels for Linux distributions that use musl libc, notably, Alpine Docker containers.

  Musllinux builds are enabled by default. To disable them on your project, add *-musllinux_* to your CIBW_SKIP/skip
  option. (#768)

• 🛠 Setting an empty string for the CIBW_*_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)
