+### v2.6.1
+
+_7 June 2022_
+
+- 🛠 Update the prerelease CPython 3.11 to 3.11.0b3
+
+### v2.6.0
+
+_25 May 2022_
+
+- 🌟 Added the ability to test building wheels on CPython 3.11! Because CPython 3.11 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.readthedocs.io/en/stable/options/#prerelease-pythons) to test. This version of cibuildwheel includes CPython 3.11.0b1. (#1109)
+- 📚 Added an interactive diagram showing how cibuildwheel works to the [docs](https://cibuildwheel.readthedocs.io/en/stable/#how-it-works) (#1100)
+
+### v2.5.0
+
+_29 April 2022_
+
+- ✨ Added support for building ABI3 wheels. cibuildwheel will now recognise when an ABI3 wheel was produced, and skip subsequent build steps where the previously built wheel is compatible. Tests still will run on all selected versions of Python, using the ABI3 wheel. Check [this entry](https://cibuildwheel.readthedocs.io/en/stable/faq/#abi3) in the docs for more info. (#1091)
+- ✨ You can now build wheels directly from sdist archives, in addition to source directories. Just call cibuildwheel with an sdist argument on the command line, like `cibuildwheel mypackage-1.0.0.tar.gz`. For more details, check the [`--help` output](https://cibuildwheel.readthedocs.io/en/stable/options/#command-line) (#1096)
+- 🐛 Fix a bug where cibuildwheel would crash when no builds are selected and `--allow-empty` is passed (#1086)
+- 🐛 Workaround a permissions issue on Linux relating to newer versions of git and setuptools_scm (#1095)
+- 📚 Minor docs improvements

 ### v2.4.0

 _2 April 2022_
@@ -212,32 +246,6 @@ _14 December 2021_
 - 🐛 Setting pip options like `PIP_USE_DEPRECATED` in `CIBW_ENVIRONMENT` no longer adversely affects cibuildwheel's ability to set up a Python environment (#956)
 - 📚 Docs fixes and improvements

-### v2.3.0
-
-_26 November 2021_
-
- 📈 cibuildwheel now defaults to manylinux2014 image for linux builds, rather than manylinux2010. If you want to stick with manylinux2010, it's simple to set this using [the image options](https://cibuildwheel.readthedocs.io/en/stable/options/#linux-image). (#926)
- ✨ You can now pass environment variables from the host machine into the Docker container during a Linux build. Check out [the docs for `CIBW_ENVIRONMENT_PASS_LINUX `](https://cibuildwheel.readthedocs.io/en/latest/options/#environment-pass) for the details. (#914)
- ✨ Added support for building PyPy 3.8 wheels. (#881)
- ✨ Added support for building Windows arm64 CPython wheels on a Windows arm64 runner. We can't test this in CI yet, so for now, this is experimental. (#920)
- 📚 Improved the deployment documentation (#911)
- 🛠 Changed the escaping behaviour inside cibuildwheel's  option placeholders e.g. `{project}` in `before_build` or `{dest_dir}` in `repair_wheel_command`. This allows bash syntax like `${SOME_VAR}` to passthrough without being interpreted as a placeholder by cibuildwheel. See [this section](https://cibuildwheel.readthedocs.io/en/stable/options/#placeholders) in the docs for more info. (#889)
- 🛠 Pip updated to 21.3, meaning it now defaults to in-tree builds again. If this causes an issue with your project, setting environment variable `PIP_USE_DEPRECATED=out-of-tree-build` is available as a temporary flag to restore the old behaviour. However, be aware that this flag will probably be removed soon. (#881)
- 🐛 You can now access the current Python interpreter using `python3` within a build on Windows (#917)
-
-### v2.2.2
-
-_26 October 2021_
-
- 🐛 Fix bug in the GitHub Action step causing a syntax error (#895)
-
-### v2.2.1
-
-_26 October 2021_
-
- 🛠 Added a `config-file` option on the GitHub Action to specify something other than pyproject.toml in your GitHub Workflow file. (#883)
- 🐛 Fix missing resources in sdist and released wheel on PyPI. We've also made some internal changes to our release processes to make them more reliable. (#893, #894)

-If you'd like to keep wheel building separate from the package itself, check out [astrofrog/autowheel](https://github.com/astrofrog/autowheel). It builds packages using cibuildwheel from source distributions on PyPI.
-
 Another very similar tool to consider is [matthew-brett/multibuild](http://github.com/matthew-brett/multibuild). `multibuild` is a shell script toolbox for building a wheel on various platforms. It is used as a basis to build some of the big data science tools, like SciPy.
+
+If you are building Rust wheels, you can get by without some of the tricks required to make GLIBC work via manylinux; this is especially relevant for cross-compiling, which is easy with Rust. See [maturin-action](https://github.com/messense/maturin-action) for a tool that is optimized for building Rust wheels and cross-compiling.

+- 🛠 Update the prerelease CPython 3.11 to 3.11.0b3
+
+### v2.6.0
+
+_25 May 2022_
+
+- 🌟 Added the ability to test building wheels on CPython 3.11! Because CPython 3.11 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.readthedocs.io/en/stable/options/#prerelease-pythons) to test. This version of cibuildwheel includes CPython 3.11.0b1. (#1109)
+- 📚 Added an interactive diagram showing how cibuildwheel works to the [docs](https://cibuildwheel.readthedocs.io/en/stable/#how-it-works) (#1100)
+
+### v2.5.0
+
+_29 April 2022_
+
+- ✨ Added support for building ABI3 wheels. cibuildwheel will now recognise when an ABI3 wheel was produced, and skip subsequent build steps where the previously built wheel is compatible. Tests still will run on all selected versions of Python, using the ABI3 wheel. Check [this entry](https://cibuildwheel.readthedocs.io/en/stable/faq/#abi3) in the docs for more info. (#1091)
+- ✨ You can now build wheels directly from sdist archives, in addition to source directories. Just call cibuildwheel with an sdist argument on the command line, like `cibuildwheel mypackage-1.0.0.tar.gz`. For more details, check the [`--help` output](https://cibuildwheel.readthedocs.io/en/stable/options/#command-line) (#1096)
+- 🐛 Fix a bug where cibuildwheel would crash when no builds are selected and `--allow-empty` is passed (#1086)
+- 🐛 Workaround a permissions issue on Linux relating to newer versions of git and setuptools_scm (#1095)
+- 📚 Minor docs improvements

 OS X/macOS allows you to specify a so-called "deployment target" version that will ensure backwards compatibility with older versions of macOS. One way to do this is by setting the `MACOSX_DEPLOYMENT_TARGET` environment variable.

 To get C++11 and C++14 support, `MACOSX_DEPLOYMENT_TARGET` needs to be set to (at least) `"10.9"`. By default, `cibuildwheel` already does this, building 64-bit-only wheels for macOS 10.9 and later.

 Visual Studio and MSVC link the compiled binary wheels to the Microsoft Visual C++ Runtime. Normally, these are included with Python, but when compiling with a newer version of Visual Studio, it is possible users will run into problems on systems that do not have these runtime libraries installed. The solution is to ask users to download the corresponding Visual C++ Redistributable from the [Microsoft website](https://support.microsoft.com/en-us/help/2977003/the-latest-supported-visual-c-downloads) and install it. Since a Python installation normally includes these VC++ Redistributable files for [the version of the MSVC compiler used to compile Python](https://wiki.python.org/moin/WindowsCompilers), this is typically only a problem when compiling a Python C extension with a newer compiler.

-Additionally, Visual Studio 2019 started linking to an even newer DLL, `VCRUNTIME140_1.dll`, besides the `VCRUNTIME140.dll` that is included with recent Python versions (starting from Python 3.5; see [here](https://wiki.python.org/moin/WindowsCompilers) for more details on the corresponding Visual Studio & MSVC versions used to compile the different Python versions). To avoid this extra dependency on `VCRUNTIME140_1.dll`, the [`/d2FH4-` flag](https://devblogs.microsoft.com/cppblog/making-cpp-exception-handling-smaller-x64/) can be added to the MSVC invocations (check out [this issue](https://github.com/pypa/cibuildwheel/issues/423) for details and references).

 The list of supported and currently selected build identifiers can also be retrieved by passing the `--print-build-identifiers` flag to cibuildwheel.
 The format is `python_tag-platform_tag`, with tags similar to those in [PEP 425](https://www.python.org/dev/peps/pep-0425/#details).
