- ✨ 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.

_16 July 2021_

- 🌟 You can now configure cibuildwheel options inside your project's `pyproject.toml`! Environment variables still work of course. Check out the [documentation](https://cibuildwheel.pypa.io/en/stable/options/#setting-options) for more info.
- 🌟 Added support for building wheels with [build](https://github.com/pypa/build), as well as pip. This feature is controlled with the [`CIBW_BUILD_FRONTEND`](https://cibuildwheel.pypa.io/en/stable/options/#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`](https://cibuildwheel.pypa.io/en/stable/options/#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)
