v2.2.0b1

Currently in prerelease. The below release notes will be condensed into a single entry on final release.

v2.2.0b1 (19 October 2021)

• 🌟 TOML option overrides. This provides much greater flexibility in configuration via pyproject.toml.

  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 for more info on the specifics.

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)

v2.1.3

• 🛠 Updated CPython 3.10 to the 3.10.0 final release.

v2.1.2

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

v2.1.1

• ✨ 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.}

v2.0.1

• 📚 Docs improvements (#767)
• 🛠 Dependency updates, including delocate 0.9.0.

v2.0.0

• 🌟 You can now configure cibuildwheel options inside your project's pyproject.toml! Environment variables still work of course. Check out the documentation for more info.
• 🌟 Added support for building wheels with build, as well as pip. This feature is controlled with the CIBW_BUILD_FRONTEND option.
• 🌟 Added the ability to test building wheels on CPython 3.10! Because CPython 3.10 is in beta, these wheels should not be distributed, because they might not be compatible with the final release, but it's available to build for testing purposes. Use the flag --prerelease-pythons or CIBW_PRERELEASE_PYTHONS to test. (#675) This version of cibuildwheel includes CPython 3.10.0b4.
• ⚠️ Removed support for building Python 2.7 and Python 3.5 wheels, for both CPython and PyPy. If you still need to build on these versions, please use the latest v1.x version. (#596)
• ✨ Added the ability to build CPython 3.8 wheels for Apple Silicon. (#704)
• 🛠 Update to the latest build dependencies, including Auditwheel 4. (#633)
• 🛠 Use the unified pypa/manylinux images to build PyPy (#671)
• 🐛 Numerous bug fixes & docs improvements
