_25 July 2021_

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

_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)
- 🛠 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

_22 June 2021_

- ✨ Adds support building macOS universal2/arm64 wheels on Python 3.8.

_28 May 2021_

- ✨ cibuildwheel is now part of the PyPA!
- 📚 Minor docs changes, fixing links related to the above transition
- 🛠 Update manylinux pins to the last version containing Python 2.7 and 3.5. (674)

_1 May 2021_

- 📚 Lots of docs improvements! (650, 623, 616, 609, 606)
- 🐛 Fix nuget "Package is not found" error on Windows. (653)
- ⚠️ cibuildwheel will no longer build Windows 2.7 wheels, unless you specify a custom toolchain using `DISTUTILS_USE_SDK=1` and `MSSdk=1`. This is because Microsoft have stopped distributing Visual C++ Compiler for Python 2.7. See [this FAQ entry](https://cibuildwheel.pypa.io/en/stable/faq/#windows-and-python-27) for more details. (649)
- 🐛 Fix crash on Windows due to missing `which` command (641).

_22 Feb 2021_

- ✨ Added `manylinux_2_24` support. To use these new Debian-based manylinux
images, set your [manylinux image](https://cibuildwheel.pypa.io/en/stable/options/#linux-image)
options to `manylinux_2_24`.
- 🛠 On macOS, we now set `MACOSX_DEPLOYMENT_TARGET` in before running
`CIBW_BEFORE_ALL`. This is useful when using `CIBW_BEFORE_ALL` to build a
shared library.
- 🛠 An empty `CIBW_BUILD` option is now the same as being unset i.e, `*`.
This makes some build matrix configuration easier. (588)
- 📚 Neatened up documentation - added tabs to a few places (576), fixed some
formatting issues.
