 <sup>¹ PyPy is only supported for manylinux wheels.</sup><br>
 <sup>² Windows arm64 support is experimental.</sup><br>
-<sup>³ Alpine 3.14 and very briefly 3.15's default python3 [was not able to load](https://github.com/pypa/cibuildwheel/issues/934) musllinux wheels. This has been fixed; please upgrade the python package if using Alpine from before the fix.</sup><br>

-- ✨ Adds support for building PyPy 3.10 wheels. (#1525)
-- 🛠 Updates the prerelease CPython 3.12 version to 3.12.0b3.
-- ✨ Allow the use of the `{wheel}` placeholder in CIBW_TEST_COMMAND (#1533)
-- 📚 Docs & examples updates (#1532, #1416)
-- ⚠️ Removed support for running cibuildwheel in Python 3.7. Python 3.7 is EOL. However, cibuildwheel continues to build Python 3.7 wheels for the moment. (#1175)
+- ✨ Adds CPython 3.13 support, under the prerelease flag [CIBW_PRERELEASE_PYTHONS](https://cibuildwheel.pypa.io/en/stable/options/#prerelease-pythons). This version of cibuildwheel uses 3.13.0b1. Free-threading mode is not available yet, waiting on official binaries (planned for beta 2) and pip support.
 
-### v2.13.1
+    While CPython is in beta, the ABI can change, so your wheels might not be compatible with the final release. For this reason, we don't recommend distributing wheels until RC1, at which point 3.13 will be available in cibuildwheel without the flag. (#1816)
+- ✨ Musllinux now defaults to `musllinux_1_2`. You can set the older `manylinux_1_1` via config if needed. (#1817)
+- 🛠 No longer pre-seed setuptools/wheel in virtual environments (#1819)
+- 🛠 Respect the constraints file when building with pip, matching build (#1818)
+- 🛠 Use uv to compile our pinned dependencies, 10x faster and doesn't require special setup (#1778)
+- 🐛 Fix an issue with the schema (#1788)
+- 📚 Document the new delocate error checking macOS versions (#1766)
+- 📚 Document Rust builds (#1816)
+- 📚 Speed up our readthedocs builds with uv, 26 seconds -> 6 seconds to install dependencies (#1816)
 
-_10 June 2023_
 
-- 🛠 Updates the prerelease CPython 3.12 version to 3.12.0b2. (#1516)
-- 🛠 Adds a moving `v<major>.<minor>` tag for use in GitHub Actions workflow files. If you use this, you'll get the latest patch release within a minor version. Additionally, Dependabot won't send you PRs for patch releases. (#1517)

+_11 March 2024_
 
-_28 May 2023_
+- 🌟 Adds the ability to inherit configuration in TOML overrides. This makes certain configurations much simpler. If you're overriding an option like `before-build` or `environment`, and you just want to add an  extra command or environment variable, you can just append (or prepend) to the previous config. See [the docs](https://cibuildwheel.pypa.io/en/stable/options/#inherit) for more information. (#1730)
+- 🌟 Adds official support for native arm64 macOS GitHub runners. To use them, just specify `macos-14` as an `os` of your job in your workflow file. You can also keep `macos-13` in your build matrix to build x86_64. Check out the new [GitHub Actions example config](https://cibuildwheel.pypa.io/en/stable/setup/#github-actions).
+- ✨ You no longer need to specify `--platform` to run cibuildwheel locally! Instead it will detect your platform automatically. This was a safety feature, no longer necessary. (#1727)
+- 🛠 Removed setuptools and wheel pinned versions. This only affects old-style projects without a `pyproject.toml`, projects with `pyproject.toml` are already getting fresh versions of their `build-system.requires` installed into an isolated environment. (#1725)
+- 🛠 Improve how the GitHub Action passes arguments (#1757)
+- 🛠 Remove a system-wide install of pipx in the GitHub Action (#1745)
+- 🐛 No longer will cibuildwheel override the PIP_CONSTRAINT environment variable when using the `build` frontend. Instead it will be extended. (#1675)
+- 🐛 Fix a bug where building and testing both x86_86 and arm64 wheels on the same runner caused the wrong architectures in the test environment (#1750)
+- 🐛 Fix a bug that prevented testing a CPython 3.8 wheel targeting macOS 11+ on x86_64 (#1768)

 # Changelog
 
+### v2.18.0
+
+_12 May 2024_
+
+- ✨ Adds CPython 3.13 support, under the prerelease flag [CIBW_PRERELEASE_PYTHONS](https://cibuildwheel.pypa.io/en/stable/options/#prerelease-pythons). This version of cibuildwheel uses 3.13.0b1. Free-threading mode is not available yet, waiting on official binaries (planned for beta 2) and pip support.
+
+    While CPython is in beta, the ABI can change, so your wheels might not be compatible with the final release. For this reason, we don't recommend distributing wheels until RC1, at which point 3.13 will be available in cibuildwheel without the flag. (#1816)
+- ✨ Musllinux now defaults to `musllinux_1_2`. You can set the older `manylinux_1_1` via config if needed. (#1817)
+- 🛠 No longer pre-seed setuptools/wheel in virtual environments (#1819)
+- 🛠 Respect the constraints file when building with pip, matching build (#1818)
+- 🛠 Use uv to compile our pinned dependencies, 10x faster and doesn't require special setup (#1778)
+- 🐛 Fix an issue with the schema (#1788)
+- 📚 Document the new delocate error checking macOS versions (#1766)
+- 📚 Document Rust builds (#1816)
+- 📚 Speed up our readthedocs builds with uv, 26 seconds -> 6 seconds to install dependencies (#1816)
+
+
+### v2.17.0
+
+_11 March 2024_
+
+- 🌟 Adds the ability to inherit configuration in TOML overrides. This makes certain configurations much simpler. If you're overriding an option like `before-build` or `environment`, and you just want to add an  extra command or environment variable, you can just append (or prepend) to the previous config. See [the docs](https://cibuildwheel.pypa.io/en/stable/options/#inherit) for more information. (#1730)
+- 🌟 Adds official support for native arm64 macOS GitHub runners. To use them, just specify `macos-14` as an `os` of your job in your workflow file. You can also keep `macos-13` in your build matrix to build x86_64. Check out the new [GitHub Actions example config](https://cibuildwheel.pypa.io/en/stable/setup/#github-actions).
+- ✨ You no longer need to specify `--platform` to run cibuildwheel locally! Instead it will detect your platform automatically. This was a safety feature, no longer necessary. (#1727)
+- 🛠 Removed setuptools and wheel pinned versions. This only affects old-style projects without a `pyproject.toml`, projects with `pyproject.toml` are already getting fresh versions of their `build-system.requires` installed into an isolated environment. (#1725)
+- 🛠 Improve how the GitHub Action passes arguments (#1757)
+- 🛠 Remove a system-wide install of pipx in the GitHub Action (#1745)
+- 🐛 No longer will cibuildwheel override the PIP_CONSTRAINT environment variable when using the `build` frontend. Instead it will be extended. (#1675)
+- 🐛 Fix a bug where building and testing both x86_86 and arm64 wheels on the same runner caused the wrong architectures in the test environment (#1750)
+- 🐛 Fix a bug that prevented testing a CPython 3.8 wheel targeting macOS 11+ on x86_64 (#1768)
+- 📚 Moved the docs onto the official PyPA domain - they're now available at https://cibuildwheel.pypa.io . (#1775)
+- 📚 Docs and examples improvements (#1762, #1734)
+
+
+### v2.16.5
+
+_30 January 2024_
+
+- 🐛 Fix an incompatibility with the GitHub Action and new GitHub Runner images for Windows that bundle Powershell 7.3+ (#1741)
+- 🛠 Preliminary support for new `macos-14` arm64 runners (#1743)
+
+### v2.16.4
+
+_28 January 2024_
+
+- 🛠 Update manylinux pins to upgrade from a problematic PyPy version. (#1737)
+
+### v2.16.3
+
+_26 January 2024_
+
+- 🐛 Fix a bug when building from sdist, where relative paths to files in the package didn't work because the working directory was wrong (#1687)
+- 🛠 Adds the ability to disable mounting the host filesystem in containers to `/host`, through the `disable_host_mount` suboption on [`CIBW_CONTAINER_ENGINE`](https://cibuildwheel.pypa.io/en/stable/options/#container-engine).
+- 📚 A lot of docs improvements! (#1708, #1705, #1686, #1679, #1667, #1665)
+
+### v2.16.2
+
+_3 October 2023_
+
+- 🛠 Updates CPython 3.12 version to 3.12.0, final release (#1635)
+- ✨ Adds a debug option [`CIBW_DEBUG_KEEP_CONTAINER`](https://cibuildwheel.pypa.io/en/stable/options/#cibw_debug_keep_container) to stop cibuildwheel deleting build containers after the build finishes. (#1620)
+- 📚 Adds support for `[tool.cibuildwheel]` checking by adding a schema compatible with the [validate-pyproject](https://github.com/abravalheri/validate-pyproject/) tool (#1622, #1628, #1629)
+- 🐛 Fix parsing of `CIBW_CONTAINER_ENGINE` and `CIBW_BUILD_FRONTEND` options to not break arguments on `:` characters (#1621)
+- 🐛 Fix the evaluation order of `CIBW_ENVIRONMENT` and `CIBW_ENVIRONMENT_PASS` so that `CIBW_ENVIRONMENT` assignments can reference environment variables passed through from the host machine. (#1617)
+- 🛠 Supports manylinux images' deferred installation of interpreters through the `manylinux-interpreters` tool (#1630)
+
+### v2.16.1

+
+### v2.16.0
+

+
+- ✨ Add the ability to pass additional flags to a build frontend through the [CIBW_BUILD_FRONTEND](https://cibuildwheel.pypa.io/en/stable/options/#build-frontend) option (#1588).
+- ✨ The environment variable SOURCE_DATE_EPOCH is now automatically passed through to container Linux builds (useful for [reproducible builds](https://reproducible-builds.org/docs/source-date-epoch/)!) (#1589)
+- 🛠 Updates the prerelease CPython 3.12 version to 3.12.0rc2 (#1604)

+- 🌟 CPython 3.12 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 3.12.0rc1, which is guaranteed to be ABI compatible with the final release. (#1565)
+- ✨ Adds musllinux_1_2 support - this allows packagers to build for musl-based Linux distributions on a more recent Alpine image, and a newer musl libc. (#1561)

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/).

-- 🛠 Changed the escaping behaviour inside cibuildwheel's  option placeholders e.g. `{project}` in `before_build` or `{dest_dir}` in `repair_wheel_command`.

+## Development
 
-### Nox support
+### Running the tests
+
+When making a change to the codebase, you can run tests locally for quicker feedback than the CI runs on a PR. You can [run them directly](#making-a-venv), but the easiest way to run tests is using [nox](https://nox.thea.codes/).
+
+You can run all the tests locally by doing:
+
+```bash
+nox -s tests
+```
+
+However, because this takes a while, you might prefer to be more specific.
+
+#### Unit tests
+
+To run the project's unit tests, do:
+
+```bash
+nox -s tests -- unit_test
+```
+
+There are a few custom options to enable different parts of the test suite - check `nox -s tests -- unit_test --help` for details.
+
+If you're calling this a lot, you might consider using the `-r` or `-R` arguments to nox to make it a bit faster. This calls pytest under the hood, so to target a specific test, use pytest's `-k` option after the `--` above to select a specific test.
+
+#### Integration tests
+
+To run the project's integration tests, do:
+
+```bash
+nox -s tests -- test
+```
+
+The integration test suite is big - it can take more than 30 minutes to run the whole thing.
+
+Because it takes such a long time, normally you'd choose specific tests to run locally, and rely on the project's CI for the rest. Use pytest's `-k` option to choose specific tests. You can pass a test name or a filename, it'll run everything that matches.
+
+```bash
+nox -s tests -- test -k <test_name_or_filename>
+# e.g.
+nox -s tests -- test -k before_build
+```
+
+A few notes-
+
+- Because they run inside a container, Linux tests can run on all platforms where Docker is installed, so they're convenient for running integration tests locally. Set CIBW_PLATFORM to do this: `CIBW_PLATFORM=linux nox -s tests -- test`.
+
+- Running the macOS integration tests requires _system installs_ of Python from python.org for all the versions that are tested. We won't attempt to install these when running locally, but you can do so manually using the URL in the error message that is printed when the install is not found.
+
+#### Making a venv
+
+More advanced users might prefer to invoke pytest directly-
+
+```bash
+python3 -m venv .venv
+source .venv/bin/activate
+pip install -e .[dev]
+# run the unit tests
+pytest unit_test
+# run the whole integration test suite
+pytest test
+# run a specific integration test
+pytest test -k test_build_frontend_args
+# run a specific integration test on a different platform
+CIBW_PLATFORM=linux pytest test -k test_build_frontend_args
+```
+
+### Linting, docs
 
 Most developer tasks have a nox interface. This allows you to very simply run tasks without worrying about setting up a development environment (as shown below). This is a slower than setting up a development environment and reusing it, but has the (important) benefit of being highly reproducible; an earlier run does not affect a current run, or anything else on your machine.
 
-Install [nox](https://nox.thea.codes); homebrew is recommend on macOS, otherwise, pipx is a great choice - in fact, you can use `pipx run nox` and avoid installing completely.
-
 You can see a list of sessions by typing `nox -l`; here are a few common ones:
 
 ```console
-nox -s lint          # Run the linters (default)
-nox -s tests         # Run the tests   (default)
-nox -s docs -- serve # Build and serve the documentation
-nox -s build         # Make SDist and wheel
+nox -s lint                    # Run the linters (default)
+nox -s tests [-- PYTEST-ARGS]  # Run the tests   (default)
+nox -s docs -- serve           # Build and serve the documentation
+nox -s build                   # Make SDist and wheel
 ```

 Linux wheels are built in [`manylinux`/`musllinux` containers](https://github.com/pypa/manylinux) to provide binary compatible wheels on Linux, according to [PEP 600](https://www.python.org/dev/peps/pep-0600/) / [PEP 656](https://www.python.org/dev/peps/pep-0656/). Because of this, when building with `cibuildwheel` on Linux, a few things should be taken into account:
 
--   Programs and libraries are not installed on the CI runner host, but rather should be installed inside the container - using `yum` for `manylinux2010` or `manylinux2014`, `apt-get` for `manylinux_2_24` and `apk` for `musllinux_1_1`, or manually. The same goes for environment variables that are potentially needed to customize the wheel building.

The same goes for environment variables that are potentially needed to customize the wheel building.
 
     `cibuildwheel` supports this by providing the [`CIBW_ENVIRONMENT`](options.md#environment) and [`CIBW_BEFORE_ALL`](options.md#before-all) options to setup the build environment inside the running container.
 
--   The project directory is copied into the container as `/project`, the output directory for the wheels to be copied out is `/output`. In general, this is handled transparently by `cibuildwheel`. For a more finegrained level of control however, the root of the host file system is mounted as `/host`, allowing for example to access shared files, caches, etc. on the host file system.  Note that `/host` is not available on CircleCI due to their Docker policies.

-With the exception of Cirrus CI, macOS CI runners are still Intel-based, and Apple Silicon wheels are not built by default on Intel runners. However, cross-compilation can be enabled by adding extra archs to the [`CIBW_ARCHS_MACOS` option](options.md#archs) - e.g. `x86_64 arm64`. Cross-compilation is provided by the Xcode toolchain.

-!!! important
-    When cross-compiling on Intel, it is not possible to test `arm64` and the `arm64` part of a `universal2` wheel.
+On GitHub Actions, `macos-14` runners are `arm64`, and `macos-13` runners are `x86_64`. So all you need to do is ensure both are in your build matrix.
 
-    `cibuildwheel` will raise a warning to notify you of this - these warnings be be silenced by skipping testing on these platforms: `CIBW_TEST_SKIP: *_arm64 *_universal2:arm64`.
+#### Cross-compiling
 
-!!! note
-    Your runner needs Xcode Command Line Tools 12.2 or later to build `universal2` or `arm64`.
+If your CI provider doesn't offer arm64 runners yet, or you want to create `universal2`, you'll have to cross-compile. Cross-compilation can be enabled by adding extra archs to the [`CIBW_ARCHS_MACOS` option](options.md#archs) - e.g. `CIBW_ARCHS_MACOS="x86_64 universal2"`. Cross-compilation is provided by Xcode toolchain v12.2+.
 
-    Only CPython 3.8 and newer support `universal2` and `arm64` wheels.
+Regarding testing,
+
+- On an arm64 runner, it is possible to test x86_64 wheels and both parts of a universal2 wheel using Rosetta 2 emulation.
+- On an x86_64 runner, arm64 code can be compiled but it can't be tested. `cibuildwheel` will raise a warning to notify you of this - these warnings can be silenced by skipping testing on these platforms: `CIBW_TEST_SKIP: "*_arm64 *_universal2:arm64"`.
 
 !!! note
     If your project uses **Poetry** as a build backend, cross-compiling on macOS [does not currently work](https://github.com/python-poetry/poetry/issues/7107). In some cases arm64 wheels can be built but their tags will be incorrect, with the platform tag showing `x86_64` instead of `arm64`.
 
     As a workaround, the tag can be fixed before running delocate to repair the wheel. The [`wheel tags`](https://wheel.readthedocs.io/en/stable/reference/wheel_tags.html) command is ideal for this. See [this workflow](https://gist.github.com/anderssonjohan/49f07e33fc5cb2420515a8ac76dc0c95#file-build-pendulum-wheels-yml-L39-L53) for an example usage of `wheel tags`.
 
-Hopefully, cross-compilation is a temporary situation. Once we have widely available Apple Silicon CI runners, we can build `arm64` wheels natively. Until then, cross-compiling `arm64` or `universal2` wheels requires opt-in by setting `CIBW_ARCHS_MACOS` on Intel runners.

 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+.
 
+### macOS: Library dependencies do not satisfy target MacOS
+
+Since delocate 0.11.0 there is added verification that the library binary dependencies match the target macOS version. This is to prevent the situation where a wheel platform tag is lower than the actual minimum macOS version required by the library. To resolve this error you need to build the library to the same macOS version as the target wheel (for example using `MACOSX_DEPLOYMENT_TARGET` environment variable).
+Alternatively, you could set `MACOSX_DEPLOYMENT_TARGET` in `CIBW_ENVIRONMENT` to correctly label the wheel as incompatible with older macOS versions.
+
+This error may happen when you install a library using a package manager like Homebrew, which compiles the library for the macOS version of the build machine. This is not suitable for wheels, as the library will only work on the same macOS version as the build machine. You should compile the library yourself, or use a precompiled binary that matches the target macOS version.

 ### 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, 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.

 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.

+
+
+### Extending existing options {: #inherit }
+
+In the TOML configuration, you can choose how tables and lists are inherited.
+By default, all values are overridden completely (`"none"`) but sometimes you'd
+rather `"append"` or `"prepend"` to an existing list or table. You can do this
+with the `inherit` table in overrides.  For example, if you want to add an environment
+variable for CPython 3.11, without `inherit` you'd have to repeat all the
+original environment variables in the override. With `inherit`, it's just:
+
+```toml
+[[tool.cibuildwheel.overrides]]
+select = "cp311*"
+inherit.environment = "append"
+environment.NEWVAR = "Added!"
+```
+
+For a table, `"append"` will replace a key if it exists, while `"prepend"` will
+only add a new key, older keys take precedence.
+
+Lists are also supported (and keep in mind that commands are lists). For
+example, you can print a message before and after a wheel is repaired:
+
+```toml
+[[tool.cibuildwheel.overrides]]
+select = "*"
+inherit.repair-wheel-command = "prepend"
+repair-wheel-command = "echo 'Before repair'"
+
+[[tool.cibuildwheel.overrides]]
+select = "*"
+inherit.repair-wheel-command = "append"
+repair-wheel-command = "echo 'After repair'"
+```
+
+As seen in this example, you can have multiple overrides match - they match top
+to bottom, with the config being accumulated. If you need platform-specific
+inheritance, you can use `select = "*-????linux_*"` for Linux, `select =
+"*-win_*"` for Windows, and `select = "*-macosx_*"` for macOS. As always,
+environment variables will completely override any TOML configuration.
