+### v2.2.0 (prerelease)
+
+_Currently in prerelease. The below release notes will be condensed into a single entry on final release._
+
+_v2.2.0a1 (23 September 2021)_
+
+- 🌟 Added support for [musllinux](https://www.python.org/dev/peps/pep-0656/). Support for this new wheel format lets projects build wheels for Linux distributions that use [musl libc](https://musl.libc.org/), notably, [Alpine](https://alpinelinux.org/) Docker containers.
+
+  Musllinux builds are enabled by default. To disable them on your project, add `*-musllinux_*` to your [`CIBW_SKIP`/`skip`](https://cibuildwheel.readthedocs.io/en/stable/options/#build-skip)
+ option. (#768)
+- 🛠 Setting an empty string for the [`CIBW_*_IMAGE`](https://cibuildwheel.readthedocs.io/en/stable/options/#manylinux-image) option will now fallthrough to the config file or cibuildwheel's default, rather than causing an error. This makes the option easier to use in CI build matricies. (#829)
+
+### v2.1.2
+
+_14 September 2021_
+
+- 🛠 Updated CPython 3.10 to 3.10.0rc2
+- 📚 Multiple docs updates
+- 🐛 Improved warnings when built binaries are bundled into the container on Linux. (#807)

-_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)
-
-### v1.11.0
-
-_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.readthedocs.io/en/stable/faq/#windows-and-python-27) for more details. (#649)
- 🐛 Fix crash on Windows due to missing `which` command (#641).
-
-### v1.10.0
-
-_22 Feb 2021_
-
- ✨ Added `manylinux_2_24` support. To use these new Debian-based manylinux
-  images, set your [manylinux image](https://cibuildwheel.readthedocs.io/en/stable/options/#manylinux-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.
-
-### v1.9.0
-
-_5 February 2021_
-
- 🌟 Added support for Apple Silicon wheels on macOS! You can now
-  cross-compile `universal2` and `arm64` wheels on your existing macOS Intel
-  runners, by setting
-  [CIBW_ARCHS_MACOS](https://cibuildwheel.readthedocs.io/en/stable/options/#archs).
-  Xcode 12.2 or later is required, but you don't need macOS 11.0 - you can
-  still build on macOS 10.15. See
-  [this FAQ entry](https://cibuildwheel.readthedocs.io/en/stable/faq/#apple-silicon)
-  for more information. (#484)
- 🌟 Added auto-detection of your package's Python compatibility, via declared
-   [`requires-python`](https://www.python.org/dev/peps/pep-0621/#requires-python)
-  in your `pyproject.toml`, or
-  [`python_requires`](https://packaging.python.org/guides/distributing-packages-using-setuptools/#python-requires)
-  in `setup.cfg` or `setup.py`. If your project has these set, cibuildwheel
-  will automatically skip builds on versions of Python that your package
-  doesn't support. Hopefully this makes the first-run experience of
-  cibuildwheel a bit easier. If you need to override this for any reason,
-  look at [`CIBW_PROJECT_REQUIRES_PYTHON`](https://cibuildwheel.readthedocs.io/en/stable/options/#requires-python).
-  (#536)
- 🌟 cibuildwheel can now be invoked as a native GitHub Action! You can now
-  invoke cibuildwheel in a GHA build step like:
-
-  ```yaml
-  - name: Build wheels
-    uses: pypa/cibuildwheel@version # e.g. v1.9.0
-    with:
-      output-dir: wheelhouse
-    # env:
-    #   CIBW_SOME_OPTION: value
-  ```
-
-  This saves a bit of boilerplate, and you can [use Dependabot to keep the
-  pinned version up-to-date](https://cibuildwheel.readthedocs.io/en/stable/faq/#automatic-updates).
-
- ✨ Added `auto64` and `auto32` shortcuts to the
-  [CIBW_ARCHS](https://cibuildwheel.readthedocs.io/en/stable/options/#archs)
-  option. (#553)
- ✨ cibuildwheel now prints a list of the wheels built at the end of each
-  run. (#570)
- 📚 Lots of minor docs improvements.
-
-### 1.8.0
-
-_22 January 2021_
-
- 🌟 Added support for emulated builds! You can now build manylinux wheels on
-  ARM64`aarch64`, as well as `ppc64le` and 's390x'. To build under emulation,
-  register QEMU via binfmt_misc and set the
-  [`CIBW_ARCHS_LINUX`](https://cibuildwheel.readthedocs.io/en/stable/options/#archs)
-  option to the architectures you want to run. See
-  [this FAQ entry](https://cibuildwheel.readthedocs.io/en/stable/faq/#emulation)
-  for more information. (#482)
- ✨ Added `CIBW_TEST_SKIP` option. This allows you to choose certain builds
-  whose tests you'd like to skip. This might be useful when running a slow
-  test suite under emulation, for example. (#537)
- ✨ Added `curly-{brace,bracket,paren}` style globbing to `CIBW_BUILD` and
-  `CIBW_SKIP`. This gives more expressivity, letting you do things like
-  `CIBW_BUILD=cp39-manylinux_{aarch64,ppc64le}`. (#527)
- 🛠 cibuildwheel will now exit with an error if it's called with options that
-  skip all builds on a platform. This feature can be disabled by adding
-  `--allow-empty` on the command line. (#545)
-
-### 1.7.4
-
-_2 January 2021_
-
- 🐛 Fix the PyPy virtualenv patch to work on macOS 10.14 (#506)
-
-### 1.7.3
-
-_1 January 2021_
-
- 🛠 Added a patch for Pypy to ensure header files are available for building
-  in a virtualenv. (#502)
- 🛠 Some preparatory work towards using cibuildwheel as a GitHub Action.
-  Check out
-  [the FAQ](https://cibuildwheel.readthedocs.io/en/stable/faq/#option-1-github-action)

-  their latest bugfix releases (#489)
- 📚 Switch to a GitHub example in the README (#479)
- 📚 Create Working Examples table, with many projects that use cibuildwheel (#474)
- 📚 Import Working Examples table and Changelog to docs

-
- 🛠 Update manylinux2010 image to resolve issues with 'yum' repositories
-  (#472)
-
-### 1.7.0
-
-_26 November 2020_

- 🐛 Fix a bug where CIBW_BEFORE_ALL runs with a very old version of Python on
-  Linux. (#464)
-
-### 1.6.4
-
-_31 October 2020_
-
- 🐛 Fix crash on Appveyor during nuget install due to old system CA
-  certificates. We now use certifi's CA certs to download files. (#455)
-

-
-_12 October 2020_
-
- 🐛 Fix missing SSL certificates on macOS (#447)

-
-_20 September 2020_
-
- 🛠 Add PPC64LE manylinux image supporting Python 3.9. (#436)
- 📚 Add project URLs to PyPI listing (#428)
-
-### 1.6.0
-
-_9 September 2020_
-
- 🌟 Add Python 3.9 support! This initial support uses release candidate
-  builds. You can start publishing wheels for Python 3.9 now, ahead of
-  the official release. (#382)
-
-  Minor note - if you're building PPC64LE wheels, the manylinux image pinned
-  by this version is
-  [still on Python 3.9b3](https://github.com/pypa/manylinux/issues/758), not a
-  release candidate. We'd advise holding off on distributing 3.9 ppc64le wheels
-  until a subsequent version of cibuildwheel.
-
- 🌟 Add Gitlab CI support. Gitlab CI can now build Linux wheels, using
-  cibuildwheel. (#419)

-
- 🐛 Fix a bug that would cause command substitutions in CIBW_ENVIRONMENT to
-  produce no output on Linux (#411)
- 🐛 Fix regression (introduced in 1.5.3) which caused BEFORE_BUILD and
-  BEFORE_ALL to be executed in the wrong directory (#410)
-

-
-### 1.5.1
-
-_25 June 2020_
-
- 🐛 Fix "OSError: [WinError 17] The system cannot move the file to a different
-  disk drive" on GitHub Actions (#388, #389)
-
-### 1.5.0
-
-_24 June 2020_
-
- 🌟 Add [`CIBW_BEFORE_ALL`](https://cibuildwheel.readthedocs.io/en/stable/options/#before-all)
-  option, which lets you run a command on the build machine before any wheels
-  are built. This is especially useful when building on Linux, to `make`
-  something external to Python, or to `yum install` a dependency. (#342)
- ✨ Added support for projects using pyproject.toml instead of setup.py
-  (#360, #358)
- ✨ Added workaround to allow Python 3.5 on Windows to pull dependencies from
-  pyproject.toml. (#358)
- 📚 Improved GitHub Actions examples and docs (#354, #362)
- 🐛 Ensure pip wheel uses the specified package, and doesn't build a wheel
-  from PyPI (#369)
- 🛠 Internal changes: using pathlib.Path, precommit hooks, testing
-  improvements.
-
-### 1.4.2
-
-_25 May 2020_
-
- 🛠 Dependency updates, including CPython 3.8.3 & manylinux images.
- 🛠 Lots of internal updates - type annotations and checking using mypy, and
-  a new integration testing system.
- ⚠️ Removed support for *running* cibuildwheel using Python 3.5. cibuildwheel
-  will continue to build Python 3.5 wheels until EOL.
-
-### 1.4.1
-
-_4 May 2020_
-
- 🐛 Fix a bug causing programs running inside the i686 manylinux images to
-  think they were running x86_64 and target the wrong architecture. (#336,
-  #338)
-
-### 1.4.0
-
-_2 May 2020_
-
- 🌟 Deterministic builds. cibuildwheel now locks the versions of the tools it
-  uses. This means that pinning your version of cibuildwheel pins the versions
-  of pip, setuptools, manylinux etc. that are used under the hood. This should
-  make things more reliable. But note that we don't control the entire build
-  environment on macOS and Windows, where the version of Xcode and Visual
-  Studio can still effect things.
-
-  This can be controlled using the [CIBW_DEPENDENCY_VERSIONS](https://cibuildwheel.readthedocs.io/en/stable/options/#dependency-versions)
-  and [manylinux image](https://cibuildwheel.readthedocs.io/en/stable/options/#manylinux-image)
-  options - if you always want to use the latest toolchain, you can still do
-  that, or you can specify your own pip constraints file and manylinux image.
-  (#256)
-
- ✨ Added `package_dir` command line option, meaning we now support building
-  a package that lives in a subdirectory and pulls in files from the wider
-  project. See [the `package_dir` option help](https://cibuildwheel.readthedocs.io/en/stable/options/#command-line-options)
-  for more information.
-
-  Note that this change makes the working directory (where you call
-  cibuildwheel from) relevant on Linux, as it's considered the 'project' and
-  will be copied into the Docker container. If your builds are slower on this
-  version, that's likely the reason. `cd` to your project and then call
-  `cibuildwheel` from there. (#319, #295)
-
- 🛠 On macOS, we make `MACOSX_DEPLOYMENT_TARGET` default to `10.9` if it's
-  not set. This should make things more consistent between Python versions.
- 🛠 Dependency updates - CPython 3.7.7, CPython 2.7.18, Pypy 7.3.1.
-
-### 1.3.0
-
-_12 March 2020_
-
- 🌟 Add support for building on GitHub Actions! Check out the
-  [docs](https://cibuildwheel.readthedocs.io/en/stable/setup/#github-actions)
-  for information on how to set it up. (#194)
- ✨ Add the `CIBW_BEFORE_TEST` option, which lets you run a command to
-  prepare the environment before your tests are run. (#242)
-
-### 1.2.0
-
-_8 March 2020_
-
- 🌟 Add support for building PyPy wheels, across Manylinux, macOS, and
-  Windows. (#185)
- 🌟 Added the ability to build ARM64 (aarch64), ppc64le, and s390x wheels,
-  using manylinux2014 and Travis CI. (#273)
- ✨ You can now build macOS wheels on Appveyor. (#230)
- 🛠 Changed default macOS minimum target to 10.9, from 10.6. This allows the
-  use of more modern C++ libraries, among other things. (#156)
- 🛠 Stop building universal binaries on macOS. We now only build x86_64
-  wheels on macOS. (#220)
- ✨ Allow chaining of commands using `&&` and `||` on Windows inside
-  CIBW_BEFORE_BUILD and CIBW_TEST_COMMAND. (#293)
- 🛠 Improved error reporting for failed Cython builds due to stale .so files
-  (#263)
- 🛠 Update CPython from 3.7.5 to 3.7.6 and from 3.8.0 to 3.8.2 on Mac/Windows
- 🛠 Improved error messages when a bad config breaks cibuildwheel's PATH
-  variable. (#264)
- ⚠️ Removed support for *running* cibuildwheel on Python 2.7. cibuildwheel
-  will continue to build Python 2.7 wheels for a little while. (#265)
-
-### 1.1.0
-
-_7 December 2019_
-
- 🌟 Add support for building manylinux2014 wheels. To use, set
-  `CIBW_MANYLINUX_X86_64_IMAGE` and CIBW_MANYLINUX_I686_IMAGE to
-  `manylinux2014`.
- ✨ Add support for [Linux on Appveyor](https://www.appveyor.com/blog/2018/03/06/appveyor-for-linux/) (#204, #207)
- ✨ Add `CIBW_REPAIR_WHEEL_COMMAND` env variable, for changing how
-  `auditwheel` or `delocate` are invoked, or testing an equivalent on
-  Windows. (#211)
- 📚 Added some travis example configs - these are available in /examples. (#228)
-
-### 1.0.0
-
-_10 November 2019_
-
- 🌟 Add support for building Python 3.8 wheels! (#180)
- 🌟 Add support for building manylinux2010 wheels. cibuildwheel will now
-  build using the manylinux2010 images by default. If your project is still
-  manylinux1 compatible, you should get both manylinux1 and manylinux2010
-  wheels - you can upload both to PyPI. If you always require manylinux1 wheels, you can
-  build using the old manylinux1 image using the [manylinux image](https://cibuildwheel.readthedocs.io/en/stable/options/#manylinux-image) option.
-  (#155)
- 📚 Documentation is now on its [own mini-site](https://cibuildwheel.readthedocs.io),
-   rather than on the README (#169)
- ✨ Add support for building Windows wheels on Travis CI. (#160)
- 🛠 If you set `CIBW_TEST_COMMAND`, your tests now run in a virtualenv. (#164)
- 🛠 Windows now uses Python as installed by nuget, rather than the versions
-  installed by the various CI providers. (#180)
- 🛠 Update Python from 2.7.16 to 2.7.17 and 3.7.4 to 3.7.5 on macOS (#171)
- ⚠️ Removed support for Python 3.4 (#168)
-
-### 0.12.0
-
-_29 September 2019_
-
- ✨ Add CIBW_TEST_EXTRAS option, to allow testing using extra_require
-  options. For example, set `CIBW_TEST_EXTRAS=test,qt` to make the wheel
-  installed with `pip install <wheel_file>[test,qt]`
- 🛠 Update Python from 3.7.2 to 3.7.4 on macOS
- 🛠 Update OpenSSL patch to 1.0.2t on macOS
-
-### 0.11.1
-
-_28 May 2019_
-
- 🐛 Fix missing file in the release tarball, that was causing problems with
-  Windows builds (#141)
-
-### 0.11.0
-
-_26 May 2019_
-
- 🌟 Add support for building on Azure pipelines! This lets you build all
-  Linux, Mac and Windows wheels on one service, so it promises to be the
-  easiest to set up! Check out the quickstart in the docs, or
-  [cibuildwheel-azure-example](https://github.com/pypa/cibuildwheel-azure-example)
-  for an example project. (#126, #132)
- 🛠 Internal change - the end-to-end test projects format was updated, so we
-  can more precisely assert what should be produced for each one. (#136, #137).

- 🛠  Update Python 3.7.0rc1 to 3.7.0 on macOS (#79)
-
-### 0.9.1
-
-_18 June 2018_
-
- 🛠 Removed the need to use `{python}` and `{pip}` in `CIBW_BEFORE_BUILD` statements, by ensuring the correct version is always on the path at `python` and `pip` instead. (#60)
- 🛠 We now patch the _ssl module on Python 3.4 and 3.5 so these versions can still make SSL web requests using TLS 1.2 while building. (#71)
-
-### 0.9.0
-
-_18 June 2018_
-
- ✨ Add support for Python 3.7 (#73)
-
-### 0.8.0
-
-_4 May 2018_
-
- ⚠️ Drop support for Python 3.3 on Linux (#67)
- 🐛 Fix TLS by updating setuptools (#69)
-
-### 0.7.1
-
-_2 April 2017_
-
- 🐛 macOS: Fix Pip bugs resulting from PyPI TLS 1.2 enforcement
- 🐛 macOS: Fix brew Python3 version problems in the CI
-
-### 0.7.0
-
-_7 January 2018_
-
- ✨ You can now specify a custom docker image using the `CIBW_MANYLINUX1_X86_64_IMAGE` and `CIBW_MANYLINUX1_I686_IMAGE` options. (#46)
- 🐛 Fixed a bug where cibuildwheel would download and build a package from PyPI(!) instead of building the package on the local machine. (#51)
-
-### 0.6.0
-
-_9 October 2017_
-
- ✨ On the Linux build, the host filesystem is now accessible via `/host` (#36)
- 🐛 Fixed a bug where setup.py scripts would run the wrong version of Python when running subprocesses on Linux (#35)
-
-### 0.5.1
-
-_10 September 2017_
-
- 🐛 Fixed a couple of bugs on Python 3.
- ✨ Added experimental support for Mac builds on [Bitrise.io](https://www.bitrise.io)
-
-### 0.5.0
-
-_7 September 2017_
-
- ✨ `CIBW_ENVIRONMENT` added. You can now set environment variables for each build, even within the Docker container on Linux. This is a big one! (#21)
- ✨ `CIBW_BEFORE_BUILD` now runs in a system shell on all platforms. You can now do things like `CIBW_BEFORE_BUILD="cmd1 && cmd2"`. (#32)
-
-### 0.4.1
-
-_14 August 2017_
-
- 🐛 Fixed a bug on Windows where subprocess' output was hidden (#23)
- 🐛 Fixed a bug on AppVeyor where logs would appear in the wrong order due to output buffering (#24, thanks @YannickJadoul!)
-
-### 0.4.0
-
-_23 July 2017_
-
- 🐛 Fixed a bug that was increasing the build time by building the wheel twice. This was a problem for large projects that have a long build time. If you're upgrading and you need the old behaviour, use `CIBW_BEFORE_BUILD={pip} install .`, or install exactly the dependencies you need in `CIBW_BEFORE_BUILD`. See #18.
-
-### 0.3.0
-
-_27 June 2017_
-
- ⚠️ Removed Python 2.6 support on Linux (#12)
-
-### 0.2.1
-
-_11 June 2017_
-
- 🛠 Changed the build process to install the package before building the wheel - this allows direct dependencies to be installed first (#9, thanks @tgarc!)
- ✨ Added Python 3 support for the main process, for systems where Python 3 is the default (#8, thanks @tgarc).
-
-### 0.2.0
-
-_13 April 2017_
-
- ✨ Added `CIBW_SKIP` option, letting users explicitly skip a build
- ✨ Added `CIBW_BEFORE_BUILD` option, letting users run a shell command before the build starts
-
-### 0.1.3
-
-_31 March 2017_
-
- 🌟 First public release!

+### v2.2.0 (prerelease)
+
+_Currently in prerelease. The below release notes will be condensed into a single entry on final release._
+
+_v2.2.0a1 (23 September 2021)_
+
+- 🌟 Added support for [musllinux](https://www.python.org/dev/peps/pep-0656/). Support for this new wheel format lets projects build wheels for Linux distributions that use [musl libc](https://musl.libc.org/), notably, [Alpine](https://alpinelinux.org/) Docker containers.
+
+  Musllinux builds are enabled by default. To disable them on your project, add `*-musllinux_*` to your [`CIBW_SKIP`/`skip`](https://cibuildwheel.readthedocs.io/en/stable/options/#build-skip)
+ option. (#768)
+- 🛠 Setting an empty string for the [`CIBW_*_IMAGE`](https://cibuildwheel.readthedocs.io/en/stable/options/#manylinux-image) option will now fallthrough to the config file or cibuildwheel's default, rather than causing an error. This makes the option easier to use in CI build matricies. (#829)
+
+### v2.1.2
+
+_14 September 2021_
+
+- 🛠 Updated CPython 3.10 to 3.10.0rc2
+- 📚 Multiple docs updates
+- 🐛 Improved warnings when built binaries are bundled into the container on Linux. (#807)
+
+### v2.1.1
+
+_7 August 2021_
+
+- ✨ Corresponding with the release of CPython 3.10.0rc1, which is ABI stable, cibuildwheel now builds CPython 3.10 by default - without the CIBW_PRERELEASE_PYTHONS flag.
+
+<sup>Note: v2.1.0 was a bad release, it was yanked from PyPI.</sup>
+
+### v2.0.1
+
+_25 July 2021_
+
+- 📚 Docs improvements (#767)
+- 🛠 Dependency updates, including delocate 0.9.0.
+
+### v2.0.0 🎉
+
+_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.readthedocs.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.readthedocs.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.readthedocs.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
+
+### v1.12.0
+
+_22 June 2021_
+
+- ✨ Adds support building macOS universal2/arm64 wheels on Python 3.8.
+
+### v1.11.1
+
+_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)
+
+### v1.11.0
+
+_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.readthedocs.io/en/stable/faq/#windows-and-python-27) for more details. (#649)
+- 🐛 Fix crash on Windows due to missing `which` command (#641).
+
+### v1.10.0
+
+_22 Feb 2021_
+
+- ✨ Added `manylinux_2_24` support. To use these new Debian-based manylinux
+  images, set your [manylinux image](https://cibuildwheel.readthedocs.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.
+
+### v1.9.0
+
+_5 February 2021_
+
+- 🌟 Added support for Apple Silicon wheels on macOS! You can now
+  cross-compile `universal2` and `arm64` wheels on your existing macOS Intel
+  runners, by setting
+  [CIBW_ARCHS_MACOS](https://cibuildwheel.readthedocs.io/en/stable/options/#archs).
+  Xcode 12.2 or later is required, but you don't need macOS 11.0 - you can
+  still build on macOS 10.15. See
+  [this FAQ entry](https://cibuildwheel.readthedocs.io/en/stable/faq/#apple-silicon)
+  for more information. (#484)
+- 🌟 Added auto-detection of your package's Python compatibility, via declared
+   [`requires-python`](https://www.python.org/dev/peps/pep-0621/#requires-python)
+  in your `pyproject.toml`, or
+  [`python_requires`](https://packaging.python.org/guides/distributing-packages-using-setuptools/#python-requires)
+  in `setup.cfg` or `setup.py`. If your project has these set, cibuildwheel
+  will automatically skip builds on versions of Python that your package
+  doesn't support. Hopefully this makes the first-run experience of
+  cibuildwheel a bit easier. If you need to override this for any reason,
+  look at [`CIBW_PROJECT_REQUIRES_PYTHON`](https://cibuildwheel.readthedocs.io/en/stable/options/#requires-python).
+  (#536)
+- 🌟 cibuildwheel can now be invoked as a native GitHub Action! You can now
+  invoke cibuildwheel in a GHA build step like:
+
+  ```yaml
+  - name: Build wheels
+    uses: pypa/cibuildwheel@version # e.g. v1.9.0
+    with:
+      output-dir: wheelhouse
+    # env:
+    #   CIBW_SOME_OPTION: value
+  ```
+
+  This saves a bit of boilerplate, and you can [use Dependabot to keep the
+  pinned version up-to-date](https://cibuildwheel.readthedocs.io/en/stable/faq/#automatic-updates).
+
+- ✨ Added `auto64` and `auto32` shortcuts to the
+  [CIBW_ARCHS](https://cibuildwheel.readthedocs.io/en/stable/options/#archs)
+  option. (#553)
+- ✨ cibuildwheel now prints a list of the wheels built at the end of each
+  run. (#570)
+- 📚 Lots of minor docs improvements.
+
+### 1.8.0
+
+_22 January 2021_
+
+- 🌟 Added support for emulated builds! You can now build manylinux wheels on
+  ARM64`aarch64`, as well as `ppc64le` and 's390x'. To build under emulation,
+  register QEMU via binfmt_misc and set the
+  [`CIBW_ARCHS_LINUX`](https://cibuildwheel.readthedocs.io/en/stable/options/#archs)
+  option to the architectures you want to run. See
+  [this FAQ entry](https://cibuildwheel.readthedocs.io/en/stable/faq/#emulation)
+  for more information. (#482)
+- ✨ Added `CIBW_TEST_SKIP` option. This allows you to choose certain builds
+  whose tests you'd like to skip. This might be useful when running a slow
+  test suite under emulation, for example. (#537)
+- ✨ Added `curly-{brace,bracket,paren}` style globbing to `CIBW_BUILD` and
+  `CIBW_SKIP`. This gives more expressivity, letting you do things like
+  `CIBW_BUILD=cp39-manylinux_{aarch64,ppc64le}`. (#527)
+- 🛠 cibuildwheel will now exit with an error if it's called with options that
+  skip all builds on a platform. This feature can be disabled by adding
+  `--allow-empty` on the command line. (#545)
+
+### 1.7.4
+
+_2 January 2021_
+
+- 🐛 Fix the PyPy virtualenv patch to work on macOS 10.14 (#506)
+
+### 1.7.3
+
+_1 January 2021_
+
+- 🛠 Added a patch for Pypy to ensure header files are available for building
+  in a virtualenv. (#502)
+- 🛠 Some preparatory work towards using cibuildwheel as a GitHub Action.
+  Check out
+  [the FAQ](https://cibuildwheel.readthedocs.io/en/stable/faq/#option-1-github-action)
+  for information on how to use it. We'll be fully updating the docs to this
+  approach in a subsequent release (#494)
+
+### 1.7.2
+
+_21 December 2020_
+
+- 🛠 Update dependencies, notably wheel==0.36.2 and pip==20.3.3, and CPython to
+  their latest bugfix releases (#489)
+- 📚 Switch to a GitHub example in the README (#479)
+- 📚 Create Working Examples table, with many projects that use cibuildwheel (#474)
+- 📚 Import Working Examples table and Changelog to docs
+
+### 1.7.1
+
+_3 December 2020_
+
+- 🛠 Update manylinux2010 image to resolve issues with 'yum' repositories
+  (#472)
+
+### 1.7.0
+
+_26 November 2020_
+
+- ✨ New logging format, that uses 'fold groups' in CI services that support
+  it. (#458)
+- 🛠 Update PyPy to 7.3.3 (#460)
+- 🐛 Fix a bug where CIBW_BEFORE_ALL runs with a very old version of Python on
+  Linux. (#464)
+
+### 1.6.4
+
+_31 October 2020_
+
+- 🐛 Fix crash on Appveyor during nuget install due to old system CA
+  certificates. We now use certifi's CA certs to download files. (#455)
+
+### 1.6.3
+
+_12 October 2020_
+
+- 🐛 Fix missing SSL certificates on macOS (#447)
+- 🛠 Update OpenSSL Python 3.5 patch to 1.1.1h on macOS (#449)
+
+### 1.6.2
+
+_9 October 2020_
+
+- ✨ Python 3.9 updated to the final release version - v3.9.0 (#440)
+- 🛠 Pypy updated to v7.3.2, adding alpha support for Python 3.7 (#430)
+
+### 1.6.1
+
+_20 September 2020_
+
+- 🛠 Add PPC64LE manylinux image supporting Python 3.9. (#436)
+- 📚 Add project URLs to PyPI listing (#428)
+
+### 1.6.0
+
+_9 September 2020_
+
+- 🌟 Add Python 3.9 support! This initial support uses release candidate
+  builds. You can start publishing wheels for Python 3.9 now, ahead of
+  the official release. (#382)
+
+  Minor note - if you're building PPC64LE wheels, the manylinux image pinned
+  by this version is
+  [still on Python 3.9b3](https://github.com/pypa/manylinux/issues/758), not a
+  release candidate. We'd advise holding off on distributing 3.9 ppc64le wheels
+  until a subsequent version of cibuildwheel.
+
+- 🌟 Add Gitlab CI support. Gitlab CI can now build Linux wheels, using
+  cibuildwheel. (#419)
+- 🐛 Fix a bug that causes pyproject.toml dependencies to fail to install on
+  Windows (#420)
+- 📚 Added some information about Windows VC++ runtimes and how they relate
+  to wheels.
+
+### 1.5.5
+
+_22 July 2020_
+
+- 🐛 Fix a bug that would cause command substitutions in CIBW_ENVIRONMENT to
+  produce no output on Linux (#411)
+- 🐛 Fix regression (introduced in 1.5.3) which caused BEFORE_BUILD and
+  BEFORE_ALL to be executed in the wrong directory (#410)
+
+### 1.5.4
+
+_19 June 2020_
+
+- 🐛 Fix a bug that would cause command substitutions in CIBW_ENVIRONMENT
+  variables to not interpret quotes in commands correctly (#406, #408)
+
+### 1.5.3
+
+_19 July 2020_
+
+- 🛠 Update CPython 3.8 to 3.8.3 (#405)
+- 🛠 Internal refactoring of Linux build, to move control flow into Python (#386)
+
+### 1.5.2
+
+_8 July 2020_
+
+- 🐛 Fix an issue on Windows where pyproject.toml would cause an error when
+  some requirements formats were used. (#401)
+- 🛠 Update CPython 3.7 to 3.7.8 (#394)
+
+### 1.5.1
+
+_25 June 2020_
+
+- 🐛 Fix "OSError: [WinError 17] The system cannot move the file to a different
+  disk drive" on GitHub Actions (#388, #389)
+
+### 1.5.0
+
+_24 June 2020_
+
+- 🌟 Add [`CIBW_BEFORE_ALL`](https://cibuildwheel.readthedocs.io/en/stable/options/#before-all)
+  option, which lets you run a command on the build machine before any wheels
+  are built. This is especially useful when building on Linux, to `make`
+  something external to Python, or to `yum install` a dependency. (#342)
+- ✨ Added support for projects using pyproject.toml instead of setup.py
+  (#360, #358)
+- ✨ Added workaround to allow Python 3.5 on Windows to pull dependencies from
+  pyproject.toml. (#358)
+- 📚 Improved GitHub Actions examples and docs (#354, #362)
+- 🐛 Ensure pip wheel uses the specified package, and doesn't build a wheel
+  from PyPI (#369)
+- 🛠 Internal changes: using pathlib.Path, precommit hooks, testing
+  improvements.
+
+### 1.4.2
+
+_25 May 2020_
+
+- 🛠 Dependency updates, including CPython 3.8.3 & manylinux images.
+- 🛠 Lots of internal updates - type annotations and checking using mypy, and
+  a new integration testing system.
+- ⚠️ Removed support for *running* cibuildwheel using Python 3.5. cibuildwheel
+  will continue to build Python 3.5 wheels until EOL.
+
+### 1.4.1
+
+_4 May 2020_
+
+- 🐛 Fix a bug causing programs running inside the i686 manylinux images to
+  think they were running x86_64 and target the wrong architecture. (#336,
+  #338)
+
+### 1.4.0
+
+_2 May 2020_
+
+- 🌟 Deterministic builds. cibuildwheel now locks the versions of the tools it
+  uses. This means that pinning your version of cibuildwheel pins the versions
+  of pip, setuptools, manylinux etc. that are used under the hood. This should
+  make things more reliable. But note that we don't control the entire build
+  environment on macOS and Windows, where the version of Xcode and Visual
+  Studio can still effect things.
+
+  This can be controlled using the [CIBW_DEPENDENCY_VERSIONS](https://cibuildwheel.readthedocs.io/en/stable/options/#dependency-versions)
+  and [manylinux image](https://cibuildwheel.readthedocs.io/en/stable/options/#linux-image)
+  options - if you always want to use the latest toolchain, you can still do
+  that, or you can specify your own pip constraints file and manylinux image.
+  (#256)
+
+- ✨ Added `package_dir` command line option, meaning we now support building
+  a package that lives in a subdirectory and pulls in files from the wider
+  project. See [the `package_dir` option help](https://cibuildwheel.readthedocs.io/en/stable/options/#command-line-options)
+  for more information.
+
+  Note that this change makes the working directory (where you call
+  cibuildwheel from) relevant on Linux, as it's considered the 'project' and
+  will be copied into the Docker container. If your builds are slower on this
+  version, that's likely the reason. `cd` to your project and then call
+  `cibuildwheel` from there. (#319, #295)
+
+- 🛠 On macOS, we make `MACOSX_DEPLOYMENT_TARGET` default to `10.9` if it's
+  not set. This should make things more consistent between Python versions.
+- 🛠 Dependency updates - CPython 3.7.7, CPython 2.7.18, Pypy 7.3.1.
+
+### 1.3.0
+
+_12 March 2020_
+
+- 🌟 Add support for building on GitHub Actions! Check out the
+  [docs](https://cibuildwheel.readthedocs.io/en/stable/setup/#github-actions)
+  for information on how to set it up. (#194)
+- ✨ Add the `CIBW_BEFORE_TEST` option, which lets you run a command to
+  prepare the environment before your tests are run. (#242)
+
+### 1.2.0
+
+_8 March 2020_
+
+- 🌟 Add support for building PyPy wheels, across Manylinux, macOS, and
+  Windows. (#185)
+- 🌟 Added the ability to build ARM64 (aarch64), ppc64le, and s390x wheels,
+  using manylinux2014 and Travis CI. (#273)
+- ✨ You can now build macOS wheels on Appveyor. (#230)
+- 🛠 Changed default macOS minimum target to 10.9, from 10.6. This allows the
+  use of more modern C++ libraries, among other things. (#156)
+- 🛠 Stop building universal binaries on macOS. We now only build x86_64
+  wheels on macOS. (#220)
+- ✨ Allow chaining of commands using `&&` and `||` on Windows inside
+  CIBW_BEFORE_BUILD and CIBW_TEST_COMMAND. (#293)
+- 🛠 Improved error reporting for failed Cython builds due to stale .so files
+  (#263)
+- 🛠 Update CPython from 3.7.5 to 3.7.6 and from 3.8.0 to 3.8.2 on Mac/Windows
+- 🛠 Improved error messages when a bad config breaks cibuildwheel's PATH
+  variable. (#264)
+- ⚠️ Removed support for *running* cibuildwheel on Python 2.7. cibuildwheel
+  will continue to build Python 2.7 wheels for a little while. (#265)
+
+### 1.1.0
+
+_7 December 2019_
+
+- 🌟 Add support for building manylinux2014 wheels. To use, set
+  `CIBW_MANYLINUX_X86_64_IMAGE` and CIBW_MANYLINUX_I686_IMAGE to
+  `manylinux2014`.

 title: Tips and tricks
 ---

-### Troubleshooting
-
-If your wheel didn't compile, check the list below for some debugging tips.
-
- A mistake in your config. To quickly test your config without doing a git push and waiting for your code to build on CI, you can test the Linux build in a Docker container. On Mac or Linux, with Docker running, try `cibuildwheel --platform linux`. You'll have to bring your config into the current environment first.
-
- Missing dependency. You might need to install something on the build machine. You can do this in `.travis.yml`, `appveyor.yml`, or `.circleci/config.yml`, with apt-get, brew or choco. Given how the Linux build works, you'll need to use the [`CIBW_BEFORE_BUILD`](options.md#before-build) option.
-
- Windows: missing C feature. The Windows C compiler doesn't support C language features invented after 1990, so you'll have to backport your C code to C90. For me, this mostly involved putting my variable declarations at the top of the function like an animal.
-
- MacOS: calling cibuildwheel from a python3 script and getting a `ModuleNotFoundError`? Due to a (fixed) [bug](https://bugs.python.org/issue22490) in CPython, you'll need to [unset the `__PYVENV_LAUNCHER__` variable](https://github.com/pypa/cibuildwheel/issues/133#issuecomment-478288597) before activating a venv.

-### Building Python 2.7 / PyPy2 wheels
-
-See the [cibuildwheel version 1 docs](https://cibuildwheel.readthedocs.io/en/1.x/) for information about building Python 2.7 or PyPy2 wheels. There are lots of tricks and workaround there that are no longer required for Python 3 in cibuildwheel 2.
+## Tips

 ### Linux builds on Docker

-Linux wheels are built in the [`manylinux` docker images](https://github.com/pypa/manylinux) to provide binary compatible wheels on Linux, according to [PEP 571](https://www.python.org/dev/peps/pep-0571/). Because of this, when building with `cibuildwheel` on Linux, a few things should be taken into account:
+Linux wheels are built in the [`manylinux`/`musllinux` docker images](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 Travis CI Ubuntu host, but rather should be installed inside of the Docker image (using `yum` for `manylinux2010` or `manylinux2014`, and `apt-get` for `manylinux_2_24`) or manually. The same goes for environment variables that are potentially needed to customize the wheel building. `cibuildwheel` supports this by providing the `CIBW_ENVIRONMENT` and `CIBW_BEFORE_BUILD` options to setup the build environment inside the running Docker image. See [the options docs](options.md#build-environment) for details on these options.
+-   Programs and libraries are not installed on the CI runner host, but rather should be installed inside of the Docker image - 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 project directory is mounted in the running Docker instance as `/project`, the output directory for the wheels as `/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 this is not available on CircleCI due to their Docker policies.
+    `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 Docker image.

- Alternative dockers images can be specified with the `CIBW_MANYLINUX_X86_64_IMAGE`, `CIBW_MANYLINUX_I686_IMAGE`, and `CIBW_MANYLINUX_PYPY_X86_64_IMAGE` options to allow for a custom, preconfigured build environment for the Linux builds. See [options](options.md#manylinux-image) for more details.

-
-These wheels are not built by default, but can be enabled by setting the [`CIBW_ARCHS_MACOS` option](options.md#archs) to `x86_64 arm64 universal2`. 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.
-
-    `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`.
-
-Hopefully, this is a temporary situation. Once we have widely available Apple Silicon CI runners, we can build and test `arm64` and `universal2` wheels more natively. That's why `universal2` wheels are not yet built by default, and require opt-in by setting `CIBW_ARCHS_MACOS`.
-
-!!! note
-    Your runner image needs Xcode Command Line Tools 12.2 or later to build `universal2` and `arm64`.

-### 'No module named XYZ' errors after running cibuildwheel on macOS
-
-`cibuildwheel` on Mac installs the distributions from Python.org system-wide during its operation. This is necessary, but it can cause some confusing errors after cibuildwheel has finished.
-
-Consider the build script:
-
-```bash
-python3 -m pip install twine cibuildwheel
-python3 -m cibuildwheel --output-dir wheelhouse
-python3 -m twine upload wheelhouse/*.whl
-# error: no module named 'twine'
-```
-
-This doesn't work because while `cibuildwheel` was running, it installed a few new versions of 'python3', so the `python3` run on line 3 isn't the same as the `python3` that ran on line 1.
-
-Solutions to this vary, but the simplest is to install tools immediately before they're used:
-
-```bash
-python3 -m pip install cibuildwheel
-python3 -m cibuildwheel --output-dir wheelhouse
-python3 -m pip install twine
-python3 -m twine upload wheelhouse/*.whl
-```
-
-### 'ImportError: DLL load failed: The specific module could not be found' error on Windows
-
-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).
-
-To add the `/d2FH4-` flag to a standard `setup.py` using `setuptools`, the `extra_compile_args` option can be used:
-
-```python
-    ext_modules=[
-        Extension(
-            'c_module',
-            sources=['extension.c'],
-            extra_compile_args=['/d2FH4-'] if sys.platform == 'win32' else []
-        )
-    ],
-```
-
-To investigate the dependencies of a C extension (i.e., the `.pyd` file, a DLL in disguise) on Windows, [Dependency Walker](http://www.dependencywalker.com/) is a great tool.

+
+### Alternatives to cibuildwheel options {: #cibw-options-alternatives}
+
+cibuildwheel provides lots of opportunities to configure the build
+environment. However, you  might consider adding this build configuration into
+the package itself - in general, this is preferred, because users of your
+package 'sdist' will also benefit.
+
+#### Missing build dependencies {: #cibw-options-alternatives-deps}
+
+If your build needs Python dependencies, rather than using CIBW_BEFORE_BUILD, it's best to add these to the
+[`build-system.requires`](https://www.python.org/dev/peps/pep-0518/#build-system-table)
+section of your pyproject.toml. For example, if your project requires Cython
+to build, your pyproject.toml might include a section like this:
+
+```toml
+[build-system]
+requires = [
+    "setuptools>=42",
+    "wheel",
+    "Cython",
+]
+
+build-backend = "setuptools.build_meta"
+```
+
+#### Actions you need to perform before building
+
+You might need to run some other commands before building, like running a
+script that performs codegen or downloading some data that's not stored in
+your source tree.
+
+Rather than using CIBW_BEFORE_ALL or CIBW_BEFORE_BUILD, you could incorporate
+these steps into your package's build process. For example, if you're using
+setuptools, you can add steps to your package's `setup.py` using a structure
+like this:
+
+    ```python
+    import subprocess
+    import setuptools
+    import setuptools.command.build_py
+
+
+    class BuildPyCommand(setuptools.command.build_py.build_py):
+      """Custom build command."""
+
+      def run(self):
+        # your custom build steps here
+        # e.g.
+        #   subprocess.run(['python', 'scripts/my_custom_script.py'], check=True)
+        setuptools.command.build_py.build_py.run(self)
+
+
+    setuptools.setup(
+        cmdclass={
+            'build_py': BuildPyCommand,
+        },
+        # Usual setup() args.
+        # ...
+    )
+    ```
+
+#### Compiler flags
+
+Your build might need some compiler flags to be set through environment variables.
+Consider incorporating these into your package, for example, in `setup.py` using [`extra_compile_args` or
+`extra_link_args`](https://docs.python.org/3/distutils/setupscript.html#other-options).

+## Troubleshooting
+

+python3 -m cibuildwheel --output-dir wheelhouse
+python3 -m twine upload wheelhouse/*.whl
+# error: no module named 'twine'
+```
+
+This doesn't work because while `cibuildwheel` was running, it installed a few new versions of 'python3', so the `python3` run on line 3 isn't the same as the `python3` that ran on line 1.
+
+Solutions to this vary, but the simplest is to install tools immediately before they're used:

+python3 -m pip install cibuildwheel

+### macOS: Passing DYLD_LIBRARY_PATH to delocate
+
+macOS has built-in [System Integrity protections](https://developer.apple.com/library/archive/documentation/Security/Conceptual/System_Integrity_Protection_Guide/RuntimeProtections/RuntimeProtections.html) which limits the use of `DYLD_LIBRARY_PATH` and `LD_LIBRARY_PATH` so that it does not automatically pass to children processes. This means if you set `DYLD_LIBRARY_PATH` before running cibuildwheel, or even set it in `CIBW_ENVIRONMENT`, it will be stripped out of the environment before delocate is called.
+
+To work around this, use a different environment variable such as `REPAIR_LIBRARY_PATH` to store the library path, and set `DYLD_LIBRARY_PATH` in [`CIBW_REPAIR_WHEEL_COMMAND_MACOS`](https://cibuildwheel.readthedocs.io/en/stable/options/#repair-wheel-command), like this:
+
+!!! tab examples "Environment variables"
+
+    ```yaml
+    CIBW_REPAIR_WHEEL_COMMAND_MACOS: >
+        DYLD_LIBRARY_PATH=$REPAIR_LIBRARY_PATH delocate-listdeps {wheel} &&
+        DYLD_LIBRARY_PATH=$REPAIR_LIBRARY_PATH delocate-wheel --require-archs {delocate_archs} -w {dest_dir} {wheel}
+    ```
+
+!!! tab examples "pyproject.toml"
+

+### 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.
+
+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).
+
+To add the `/d2FH4-` flag to a standard `setup.py` using `setuptools`, the `extra_compile_args` option can be used:
+
+```python
+    ext_modules=[
+        Extension(
+            'c_module',
+            sources=['extension.c'],
+            extra_compile_args=['/d2FH4-'] if sys.platform == 'win32' else []
+        )
+    ],
+```
+
+To investigate the dependencies of a C extension (i.e., the `.pyd` file, a DLL in disguise) on Windows, [Dependency Walker](http://www.dependencywalker.com/) is a great tool.

+happening in manylinux Docker containers, they're perfectly reproducible.
+
+Install cibuildwheel and run a build like this:
+
+```sh
+pip install cibuildwheel
+cibuildwheel --platform linux
+```
+
+Or, using [pipx](https://github.com/pypa/pipx):
+```sh
+pipx run cibuildwheel --platform linux
+```
+
+You should see the builds taking place. You can experiment with options using environment variables or pyproject.toml.
+
+!!! tab "Environment variables"
+
+    cibuildwheel will read config from the environment. Syntax varies, depending on your shell:
+
+    > POSIX shell (Linux/macOS)
+
+    ```sh
+    # run a command to set up the build system
+    export CIBW_BEFORE_ALL='apt install libpng-dev'
+
+    cibuildwheel --platform linux
+    ```
+
+    > CMD (Windows)
+
+    ```bat
+    set CIBW_BEFORE_ALL='apt install libpng-dev'
+
+    cibuildwheel --platform linux
+    ```
+
+!!! tab "pyproject.toml"
+
+    If you write your options into [`pyproject.toml`](options.md#configuration-file), you can work on your options locally, and they'll be automatically picked up when running in CI.
+
+    > pyproject.toml
+
+    ```
+    [tool.cibuildwheel]
+    before-all = "apt install libpng-dev"
+    ```
+
+    Then invoke cibuildwheel, like:
+
+    ```console
+    cibuildwheel --platform linux
+    ```
