-### v2.8.0
+### v2.11.0

-_5 July 2022_
+_13 October 2022_

- ✨ You can now run cibuildwheel on Podman, as an alternate container engine to Docker, which remains the default. This is useful in environments where a Docker daemon isn't available, for example, it can be run inside a Docker container, or without root access. To use Podman, set the [`CIBW_CONTAINER_ENGINE`](https://cibuildwheel.readthedocs.io/en/stable/options/#container-engine) option. (#966)
- ✨ Adds support for building `py3-none-{platform}` wheels. These wheels contain native extension code, but don't use the Python APIs. Typically, they're bridged to Python using a FFI module like [ctypes](https://docs.python.org/3/library/ctypes.html) or [cffi](https://cffi.readthedocs.io/en/latest/). Because they don't use Python ABI, the wheels are more compatible - they work across many Python versions. Check out this [example ctypes project](https://github.com/joerick/python-ctypes-package-sample) to see an example of how it works. (#1151)
- 🛠 cibuildwheel will now error if multiple builds in a single run produce the same wheel filename, as this indicates a misconfiguration. (#1152)
- 📚 A few docs improvements and updates to keep things up-to-date.
+- 🌟 Adds support for cross-compiling Windows ARM64 wheels. To use this feature, add `ARM64` to the [CIBW_ARCHS](https://cibuildwheel.readthedocs.io/en/stable/options/#archs) option on a Windows Intel runner. (#1144)
+- ✨ Adds support for building Linux aarch64 wheels on Circle CI. (#1307)
+- ✨ Adds support for building Windows wheels on Gitlab CI. (#1295)
+- ✨ Adds support for building Linux aarch64 wheels under emulation on Gitlab CI. (#1295)
+- ✨ Adds the ability to test `cp38-macosx_arm64` wheels on a native arm64 runner. To do this, you'll need to preinstall the (experimental) [universal2 version of CPython 3.8](https://www.python.org/ftp/python/3.8.10/python-3.8.10-macos11.pkg) on your arm64 runner before invoking cibuildwheel. Note: it is not recommended to build x86_64 wheels with this setup, your wheels will have limited compatibility wrt macOS versions. (#1283)
+- 🛠 Improved error messages when using custom Docker images and Python cannot be found at the correct path. (#1298)
+- 📚 Sample configs for Azure Pipelines and Travis CI updated (#1296)
+- 📚 Other docs improvements - including more information about using Homebrew for build dependencies (#1290)

-### v2.7.0
+### v2.10.2

-_17 June 2022_
+_25 September 2022_

- 🌟 Added support for the new `manylinux_2_28` images. These new images are based on AlmaLinux, the community-driven successor to CentOS, unlike manylinux_2_24, which was based on Debian. To build on these images, set your [`CIBW_MANYLINUX_*_IMAGE`](https://cibuildwheel.readthedocs.io/en/stable/options/#linux-image) option to `manylinux_2_28`. (#1026)
- 🐛 Fix a bug where tests were not being run on CPython 3.11 (when CIBW_PRERELEASE_PYTHONS was set) (#1138)
- ✨ You can now build Linux wheels on Windows, as long as you have Docker installed and set to 'Linux containers' (#1117)
- 🐛 Fix a bug on macOS that caused cibuildwheel to crash trying to overwrite a previously-built wheel of the same name. (#1129)
+- 🐛 Fix a bug that caused `win32` identifiers to fail when used with `--only`. (#1282)
+- 🐛 Fix computation of `auto`/`auto64`/`auto32` archs when targeting a different platform to the one that you're running cibuildwheel on. (#1266)
+- 📚 Fix an mistake in the 'how it works' diagram. (#1274)

-### v2.6.1
+### v2.10.1

-_7 June 2022_
+_18 September 2022_

- 🛠 Update the prerelease CPython 3.11 to 3.11.0b3
+- 🐛 Fix a bug that stopped environment variables specified in TOML from being expanded. (#1273)

-### v2.6.0
+### v2.10.0

-_25 May 2022_
+_13 September 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)
+- 🌟 Adds support for [building wheels on Cirrus CI](https://cibuildwheel.readthedocs.io/en/stable/setup/#cirrus-ci). This is exciting for us, as it's the first public CI platform that natively supports macOS Apple Silicon (aka. M1, `arm64`) runners. As such, it's the first platform that you can natively build _and test_ macOS `arm64` wheels. It also has native Linux ARM (aarch64) runners, for fast, native builds there. (#1191)
+- 🌟 Adds support for running cibuildwheel on Apple Silicon machines. For a while, we've supported cross-compilation of Apple Silicon wheels on `x86_64`, but now that we have Cirrus CI we can run our test suite and officially support running cibuildwheel on `arm64`. (#1191)
+- ✨ Adds the `--only` [command line option](https://cibuildwheel.readthedocs.io/en/stable/options/#command-line), to specify a single build to run. Previously, it could be cumbersome to set all the build selection options to target a specific build - for example, you might have to run something like `CIBW_BUILD=cp39-manylinux_x86_64 cibuildwheel --platform linux --archs x86_64`. The new `--only` option overrides all the build selection options to simplify running a single build, which now looks like `cibuildwheel --only cp39-manylinux_x86_64`. (#1098)
+- ✨ Adds the [`CIBW_CONFIG_SETTINGS`](https://cibuildwheel.readthedocs.io/en/stable/options/#config-settings) option, so you can pass arguments to your package's build backend (#1244)
+- 🛠 Updates the CPython 3.11 version to the latest release candidate - v3.11.0rc2. (#1265)
+- 🐛 Fix a bug that can cause a RecursionError on Windows when building from an sdist. (#1253)
+- 🛠 Add support for the s390x architecture on manylinux_2_28 (#1255)

-### v2.5.0
+### v2.9.0

-_29 April 2022_
+_11 August 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
+- 🌟 CPython 3.11 wheels are now built by default - without the CIBW_PRERELEASE_PYTHONS flag. It's time to build and upload these wheels to PyPI! This release includes CPython 3.11.0rc1, which is guaranteed to be ABI compatible with the final release. (#1226)
+- ⚠️ Removed support for running cibuildwheel in Python 3.6. Python 3.6 is EOL. However, cibuildwheel continues to build CPython 3.6 wheels for the moment. (#1175)
+- ✨ Improved error messages when misspelling TOML options, suggesting close matches (#1205)
+- 🛠 When running on Apple Silicon (so far, an unsupported mode of operation), cibuildwheel no longer builds universal2 wheels by default - just arm64. See [#1204](https://github.com/pypa/cibuildwheel/issues/1204) for discussion. We hope to release official support for native builds on Apple Silicon soon! (#1217)

+# Changelog
+
+### v2.11.0
+
+_13 October 2022_
+
+- 🌟 Adds support for cross-compiling Windows ARM64 wheels. To use this feature, add `ARM64` to the [CIBW_ARCHS](https://cibuildwheel.readthedocs.io/en/stable/options/#archs) option on a Windows Intel runner. (#1144)
+- ✨ Adds support for building Linux aarch64 wheels on Circle CI. (#1307)
+- ✨ Adds support for building Windows wheels on Gitlab CI. (#1295)
+- ✨ Adds support for building Linux aarch64 wheels under emulation on Gitlab CI. (#1295)
+- ✨ Adds the ability to test `cp38-macosx_arm64` wheels on a native arm64 runner. To do this, you'll need to preinstall the (experimental) [universal2 version of CPython 3.8](https://www.python.org/ftp/python/3.8.10/python-3.8.10-macos11.pkg) on your arm64 runner before invoking cibuildwheel. Note: it is not recommended to build x86_64 wheels with this setup, your wheels will have limited compatibility wrt macOS versions. (#1283)
+- 🛠 Improved error messages when using custom Docker images and Python cannot be found at the correct path. (#1298)
+- 📚 Sample configs for Azure Pipelines and Travis CI updated (#1296)
+- 📚 Other docs improvements - including more information about using Homebrew for build dependencies (#1290)
+
+### v2.10.2
+
+_25 September 2022_
+
+- 🐛 Fix a bug that caused `win32` identifiers to fail when used with `--only`. (#1282)
+- 🐛 Fix computation of `auto`/`auto64`/`auto32` archs when targeting a different platform to the one that you're running cibuildwheel on. (#1266)
+- 📚 Fix an mistake in the 'how it works' diagram. (#1274)
+
+### v2.10.1
+
+_18 September 2022_
+
+- 🐛 Fix a bug that stopped environment variables specified in TOML from being expanded. (#1273)
+
+### v2.10.0
+
+_13 September 2022_
+
+- 🌟 Adds support for [building wheels on Cirrus CI](https://cibuildwheel.readthedocs.io/en/stable/setup/#cirrus-ci). This is exciting for us, as it's the first public CI platform that natively supports macOS Apple Silicon (aka. M1, `arm64`) runners. As such, it's the first platform that you can natively build _and test_ macOS `arm64` wheels. It also has native Linux ARM (aarch64) runners, for fast, native builds there. (#1191)
+- 🌟 Adds support for running cibuildwheel on Apple Silicon machines. For a while, we've supported cross-compilation of Apple Silicon wheels on `x86_64`, but now that we have Cirrus CI we can run our test suite and officially support running cibuildwheel on `arm64`. (#1191)
+- ✨ Adds the `--only` [command line option](https://cibuildwheel.readthedocs.io/en/stable/options/#command-line), to specify a single build to run. Previously, it could be cumbersome to set all the build selection options to target a specific build - for example, you might have to run something like `CIBW_BUILD=cp39-manylinux_x86_64 cibuildwheel --platform linux --archs x86_64`. The new `--only` option overrides all the build selection options to simplify running a single build, which now looks like `cibuildwheel --only cp39-manylinux_x86_64`. (#1098)
+- ✨ Adds the [`CIBW_CONFIG_SETTINGS`](https://cibuildwheel.readthedocs.io/en/stable/options/#config-settings) option, so you can pass arguments to your package's build backend (#1244)
+- 🛠 Updates the CPython 3.11 version to the latest release candidate - v3.11.0rc2. (#1265)
+- 🐛 Fix a bug that can cause a RecursionError on Windows when building from an sdist. (#1253)
+- 🛠 Add support for the s390x architecture on manylinux_2_28 (#1255)
+
+### v2.9.0
+
+_11 August 2022_
+
+- 🌟 CPython 3.11 wheels are now built by default - without the CIBW_PRERELEASE_PYTHONS flag. It's time to build and upload these wheels to PyPI! This release includes CPython 3.11.0rc1, which is guaranteed to be ABI compatible with the final release. (#1226)
+- ⚠️ Removed support for running cibuildwheel in Python 3.6. Python 3.6 is EOL. However, cibuildwheel continues to build CPython 3.6 wheels for the moment. (#1175)
+- ✨ Improved error messages when misspelling TOML options, suggesting close matches (#1205)
+- 🛠 When running on Apple Silicon (so far, an unsupported mode of operation), cibuildwheel no longer builds universal2 wheels by default - just arm64. See [#1204](https://github.com/pypa/cibuildwheel/issues/1204) for discussion. We hope to release official support for native builds on Apple Silicon soon! (#1217)
+
+### v2.8.1
+
+_18 July 2022_
+
+- 🐛 Fix a bug when building CPython 3.8 wheels on an Apple Silicon machine where testing would always fail. cibuildwheel will no longer attempt to test the arm64 part of CPython 3.8 wheels because we use the x86_64 installer of CPython 3.8 due to its macOS system version backward-compatibility. See [#1169](https://github.com/pypa/cibuildwheel/pull/1169) for more details. (#1171)
+- 🛠 Update the prerelease CPython 3.11 to 3.11.0b4. (#1180)
+- 🛠 The GitHub Action will ensure a compatible version of Python is installed on the runner (#1114)
+- 📚 A few docs improvements

 ### v2.8.0

 _5 July 2022_

- ✨ You can now run cibuildwheel on Podman, as an alternate container engine to Docker, which remains the default. This is useful in environments where a Docker daemon isn't available, for example, it can be run inside a Docker container, or without root access. To use Podman, set the [`CIBW_CONTAINER_ENGINE`](https://cibuildwheel.readthedocs.io/en/stable/options/#container-engine) option. (#966)
- ✨ Adds support for building `py3-none-{platform}` wheels. These wheels contain native extension code, but don't use the Python APIs. Typically, they're bridged to Python using a FFI module like [ctypes](https://docs.python.org/3/library/ctypes.html) or [cffi](https://cffi.readthedocs.io/en/latest/). Because they don't use Python ABI, the wheels are more compatible - they work across many Python versions. Check out this [example ctypes project](https://github.com/joerick/python-ctypes-package-sample) to see an example of how it works. (#1151)

+
+**If your build is linking into a native library dependency**, you can build/install that in [`CIBW_BEFORE_ALL`](options.md#before-all). However, on Linux, Mac (and Windows if you're using [delvewheel]), the library that you install will be bundled into the wheel in the [repair step]. So take care to ensure that
+
+- the bundled library doesn't accidentally increase the minimum system requirements (such as the minimum macOS version)
+- the bundled library matches the architecture of the wheel you're building when cross-compiling
+
+This is particularly an issue on macOS, where de facto package manager Homebrew will install libraries that are compiled for the specific version of macOS that the build machine is running, rendering the wheels useless for any previous version. And brew will not install the right arch for cross compilation of Apple Silicon wheels.
+
+For these reasons, it's strongly recommended to not use brew for native library dependencies. Instead, we recommend compiling the library yourself. If you compile in the [`CIBW_BEFORE_ALL`](options.md#before-all) step, cibuildwheel will have already set the appropriate `MACOSX_DEPLOYMENT_TARGET` env var, so the library will target the correct version of macOS.
+
+!!! tip

-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.

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.

 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). CPython 3.8.3 and all versions after it have this extra DLL, so it is only needed for 3.8 and earlier.

+### Windows ARM64 builds {: #windows-arm64}
+
+`cibuildwheel` supports cross-compiling `ARM64` wheels on all Windows runners, but a native ARM64 runner is required for testing. On non-native runners, tests for ARM64 wheels will be automatically skipped with a warning. Add `*-win_arm64` to your `CIBW_TEST_SKIP` setting to suppress the warning.
+
+Cross-compilation on Windows relies on a supported build backend. Supported backends use an environment variable to specify their target platform (the one they are compiling native modules for, as opposed to the one they are running on), which is set in [cibuildwheels/windows.py](https://github.com/pypa/cibuildwheel/blob/main/cibuildwheel/windows.py) before building. Currently, `setuptools>=65.4.1` and `setuptools_rust` are the only supported backends.
+
+By default, `ARM64` is not enabled when running on non-ARM64 runners. Use [`CIBW_ARCHS`](options.md#archs) to select it.
