• 🌟 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
