-- 🐛 Fix a bug that stopped environment variables specified in TOML from being expanded. (#1273)
+- ✨ Adds support for PyPy arm64 wheels. This means that you can build PyPy wheels for Apple Silicon machines. Cross-compilation is not supported for these wheels, so you'll have to build on an Apple Silicon machine. (#1372)
+- 🛠 Pinned version updates, including PyPy to v7.3.11 and setuptools to 66.0.0.

-- 🌟 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)
+- 🐛 Fix a bug that caused missing wheels on Windows when a test was skipped using CIBW_TEST_SKIP (#1377)
+- 🛠 Updates CPython 3.11 to 3.11.1 (#1371)
+- 🛠 Updates PyPy to 7.3.10, except on macOS which remains on 7.3.9 due to a bug on that platform. (#1371)
+- 📚 Added a reference to abi3audit to the docs (#1347)

-- 🌟 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)
+- ✨ Improves the 'build options' log output that's printed at the start of each run (#1352)
+- ✨ Added a friendly error message to a common misconfiguration of the `CIBW_TEST_COMMAND` option - not specifying path using the `{project}` placeholder (#1336)
+- 🛠 The GitHub Action now uses Powershell on Windows to avoid occasional incompabilities with bash (#1346)

-- 🐛 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
+- 🛠 Updates CPython 3.11 to 3.11.0 - final release (#1327)
+- 🛠 Simplify the default macOS repair command (#1322)
+- 🛠 Fix the default `MACOSX_DEPLOYMENT_TARGET` on arm64 (#1312)
+- 🛠 Hide irrelevant pip warnings on linux (#1311)
+- 🐛 Fix a bug that caused the stdout and stderr of commands in containers to be in the wrong order Previously, stdout could appear after stderr. (#1324)
+- 📚 Added [a FAQ entry](https://cibuildwheel.readthedocs.io/en/stable/faq/#macos-building-cpython-38-wheels-on-arm64) describing how to perform native builds of CPython 3.8 wheels on Apple Silicon. (#1323)
+- 📚 Other docs improvements

 # Changelog
 
+### v2.12.1
+
+_11 March 2023_
+
+- 🐛 Fix a bug that prevented the use of CIBW_CONFIG_SETTINGS with the 'pip' build backend. (#1430)
+
+### v2.12.0
+
+_16 Jan 2023_
+
+- ✨ Adds support for PyPy arm64 wheels. This means that you can build PyPy wheels for Apple Silicon machines. Cross-compilation is not supported for these wheels, so you'll have to build on an Apple Silicon machine. (#1372)
+- 🛠 Pinned version updates, including PyPy to v7.3.11 and setuptools to 66.0.0.
+
+### v2.11.4
+
+_24 Dec 2022_
+
+- 🐛 Fix a bug that caused missing wheels on Windows when a test was skipped using CIBW_TEST_SKIP (#1377)
+- 🛠 Updates CPython 3.11 to 3.11.1 (#1371)
+- 🛠 Updates PyPy to 7.3.10, except on macOS which remains on 7.3.9 due to a bug on that platform. (#1371)
+- 📚 Added a reference to abi3audit to the docs (#1347)
+
+### v2.11.3
+
+_5 Dec 2022_
+
+- ✨ Improves the 'build options' log output that's printed at the start of each run (#1352)
+- ✨ Added a friendly error message to a common misconfiguration of the `CIBW_TEST_COMMAND` option - not specifying path using the `{project}` placeholder (#1336)
+- 🛠 The GitHub Action now uses Powershell on Windows to avoid occasional incompabilities with bash (#1346)
+
+### v2.11.2
+
+_26 October 2022_
+
+- 🛠 Updates CPython 3.11 to 3.11.0 - final release (#1327)
+- 🛠 Simplify the default macOS repair command (#1322)
+- 🛠 Fix the default `MACOSX_DEPLOYMENT_TARGET` on arm64 (#1312)
+- 🛠 Hide irrelevant pip warnings on linux (#1311)
+- 🐛 Fix a bug that caused the stdout and stderr of commands in containers to be in the wrong order Previously, stdout could appear after stderr. (#1324)
+- 📚 Added [a FAQ entry](https://cibuildwheel.readthedocs.io/en/stable/faq/#macos-building-cpython-38-wheels-on-arm64) describing how to perform native builds of CPython 3.8 wheels on Apple Silicon. (#1323)
+- 📚 Other docs improvements
+
+### v2.11.1
+
+_13 October 2022_
+
+- 🛠 Updates to the latest manylinux images, and updates CPython 3.10 to 3.10.8.
+
+### 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)

 - ✨ 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. This works the same as ABI3 - wheels won't be rebuilt, but tests will still be run across all selected versions of Python.
 
-  > 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.

+Sometimes a build will fail due to a missing dependency.
+
+**If the build is missing a Python package**, you should [add it to pyproject.toml](#cibw-options-alternatives-deps).
+
+**If you need a build tool** (e.g. cmake, automake, ninja), you can install it through a package manager like apt/yum, brew or choco, using the [`CIBW_BEFORE_ALL`](options.md#before-all) option.
+
+**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
+    For build steps, Homebrew is still a great resource - you can [look up the build formula](https://formulae.brew.sh/) and use that as a starting point.

+### macOS: Building CPython 3.8 wheels on arm64
+
+If you're building on an arm64 runner, you might notice something strange about CPython 3.8 - unlike Python 3.9+, it's cross-compiled to arm64 from an x86_64 version of Python running under Rosetta emulation. This is because (despite the prevalence of arm64 versions of Python 3.8 from Apple and Homebrew) there is no officially supported Python.org installer of Python 3.8 for arm64.
+
+This is fine for simple C extensions, but for more complicated builds on arm64 it becomes an issue.
+
+So, if the cross-compilation is an issue for you, there is an 'experimental' installer available that's built natively for arm64.
+
+To use this installer and perform native CPython 3.8 building, before invoking cibuildwheel, install the universal2 version of Python on your arm64 runner, something like:
+
+
+```bash
+curl -o /tmp/Python38.pkg https://www.python.org/ftp/python/3.8.10/python-3.8.10-macos11.pkg
+sudo installer -pkg /tmp/Python38.pkg -target /
+sh "/Applications/Python 3.8/Install Certificates.command"
+```
+
+Then cibuildwheel will detect that it's installed and use it instead. However, you probably don't want to build x86_64 wheels on this Python, unless you're happy with them only supporting macOS 11+.
+
 ### Windows: 'ImportError: DLL load failed: The specific module could not be found'
 
-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.
+Visual Studio and MSVC link the compiled binary wheels to the Microsoft Visual C++ Runtime. Normally, the C parts of the runtime are included with Python, but the C++ components are not. When compiling modules using C++, it is possible users will run into problems on systems that do not have the full set of 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.
 
 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.
