cibuildwheel

• 🛠 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 describing how to perform native builds of CPython 3.8 wheels on Apple Silicon. (#1323)
• 📚 Other docs improvements

• 🛠 Updates to the latest manylinux images, and updates CPython 3.10 to 3.10.8.

• 🌟 Adds support for cross-compiling Windows ARM64 wheels. To use this feature, add ARM64 to the CIBW_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 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)

• 🐛 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)

• 🐛 Fix a bug that stopped environment variables specified in TOML from being expanded. (#1273)

• 🌟 Adds support for building wheels on 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, 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 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)

• 🌟 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 for discussion. We hope to release official support for native builds on Apple Silicon soon! (#1217)

• 🐛 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 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

• ✨ 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 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 or cffi. Because they don't use Python ABI, the wheels are more compatible - they work across many Python versions.

  Check out this example ctypes project 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.

• 🌟 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 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)

• 🛠 Update the prerelease CPython 3.11 to 3.11.0b3

• 🌟 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 to test. This version of cibuildwheel includes CPython 3.11.0b1. (#1109)
• 📚 Added an interactive diagram showing how cibuildwheel works to the docs (#1100)

• ✨ 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 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 (#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

• ✨ cibuildwheel now supports running locally on Windows and macOS (as well as Linux). On macOS, you'll have to install the versions of Pythons that you want to use from Python.org, and cibuildwheel will use them. On Windows, cibuildwheel will install it's own versions of Python. Check out the documentation for instructions. (#974)
• ✨ Added support for building PyPy 3.9 wheels. (#1031)
• ✨ Listing at the end of the build now displays the size of each wheel (#975)
• 🐛 Workaround a connection timeout bug on Travis CI ppc64le runners (#906)
• 🐛 Fix an encoding error when reading setup.py in the wrong encoding (#977)
• 🛠 Setuptools updated to 61.3.0, including experimental support for reading config from pyproject.toml(PEP 621). This could change the behaviour of your build if you have a pyproject.toml with a [project] table, because that takes precedence over setup.py and setup.cfg. Check out the setuptools docs and the project metadata specification for more info.
• 🛠 Many other dependency updates.
• 📚 Minor docs improvements

• 🐛 Setting pip options like PIP_USE_DEPRECATED in CIBW_ENVIRONMENT no longer adversely affects cibuildwheel's ability to set up a Python environment (#956)
• 📚 Docs fixes and improvements

• 📈 cibuildwheel now defaults to manylinux2014 image for linux builds, rather than manylinux2010. If you want to stick with manylinux2010, it's simple to set this using the image options. (#926)
• ✨ You can now pass environment variables from the host machine into the Docker container during a Linux build. Check out the docs for CIBW_ENVIRONMENT_PASS_LINUX for the details. (#914)
• ✨ Added support for building PyPy 3.8 wheels. (#881)
• ✨ Added support for building Windows arm64 CPython wheels on a Windows arm64 runner. We can't test this in CI yet, so for now, this is experimental. (#920)
• 📚 Improved the deployment documentation (#911)
• 🛠 Changed the escaping behaviour inside cibuildwheel's option placeholders e.g. {project} in before_build or {dest_dir} in repair_wheel_command. This allows bash syntax like ${SOME_VAR} to passthrough without being interpreted as a placeholder by cibuildwheel. See this section in the docs for more info. (#889)
• 🛠 Pip updated to 21.3, meaning it now defaults to in-tree builds again. If this causes an issue with your project, setting environment variable PIP_USE_DEPRECATED=out-of-tree-build is available as a temporary flag to restore the old behaviour. However, be aware that this flag will probably be removed soon. (#881)
• 🐛 You can now access the current Python interpreter using python3 within a build on Windows (#917)

• 🐛 Fix bug in the GitHub Action step causing a syntax error (#895)

• 🛠 Added a config-file option on the GitHub Action to specify something other than pyproject.toml in your GitHub Workflow file. (#883)
• 🐛 Fix missing resources in sdist and released wheel on PyPI. We've also made some internal changes to our release processes to make them more reliable. (#893, #894)

• 🛠 Added a config-file option on the GitHub Action to specify something other than pyproject.toml in your GitHub Workflow file. (#883)
• 🐛 Fix missing resources in sdist and released wheel on PyPI. We've made some internal change to our release processes to make them more reliable. (#893, #894)

• 🌟 Added support for musllinux. Support for this new wheel format lets projects build wheels for Linux distributions that use musl libc, notably, Alpine Docker containers. (#768)

  Musllinux builds are enabled by default. If you're not ready to build musllinux, add *-musllinux_* to your CIBW_SKIP/skip option. Or, you might have to make some changes to your options - to simplify that process, you can use...

• 🌟 TOML option overrides! This provides much greater flexibility in configuration via pyproject.toml. (#854)

  You can now set build options for any subset of your builds using a match pattern. So, for example, you can customise CPython 3.8 builds with an override on cp38-* or musllinux builds by selecting *musllinux*. Check out the docs for more info on the specifics.

• 🛠 Added support for building PyPy wheels on macOS 11 CI runners. (#875)

• 🛠 Setting an empty string for the CIBW_*_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)

• 🛠 Support for TOML 1.0 when reading config files, via the tomli package. (#876)

Currently in prerelease. The below release notes will be condensed into a single entry on final release.

v2.2.0b1 (19 October 2021)

• 🌟 TOML option overrides. This provides much greater flexibility in configuration via pyproject.toml.

  You can now set build options for any subset of your builds using a match pattern. So, for example, you can customise CPython 3.8 builds with an override on cp38-* or musllinux builds by selecting *musllinux*. Check out the docs for more info on the specifics.

v2.2.0a1 (23 September 2021)

• 🌟 Added support for musllinux. Support for this new wheel format lets projects build wheels for Linux distributions that use musl libc, notably, Alpine Docker containers.

  Musllinux builds are enabled by default. To disable them on your project, add *-musllinux_* to your CIBW_SKIP/skip option. (#768)

• 🛠 Setting an empty string for the CIBW_*_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)

• 🛠 Updated CPython 3.10 to the 3.10.0 final release.

• 🛠 Updated CPython 3.10 to 3.10.0rc2
• 📚 Multiple docs updates
• 🐛 Improved warnings when built binaries are bundled into the container on Linux. (#807)

• ✨ 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.

^{Note: v2.1.0 was a bad release, it was yanked from PyPI.}

• 📚 Docs improvements (#767)
• 🛠 Dependency updates, including delocate 0.9.0.

• 🌟 You can now configure cibuildwheel options inside your project's pyproject.toml! Environment variables still work of course. Check out the documentation for more info.
• 🌟 Added support for building wheels with build, as well as pip. This feature is controlled with the CIBW_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 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)

• ✨ Adds support building universal2/arm64 wheels on Python 3.8.

• ✨ 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)

• 📚 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 for more details. (#649)
• 🐛 Fix crash on Windows due to missing which command (#641).

• ✨ Added manylinux_2_24 support. To use these new Debian-based manylinux images, set your manylinux image options to manylinux_2_24. (#595)
• 🛠 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. (#590)
• 🛠 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.

• 🌟 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. 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 for more information. (#484)

• 🌟 Added auto-detection of your package's Python compatibility, via declared requires-python in your pyproject.toml, or 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. (#536)

• 🌟 cibuildwheel can now be invoked as a native GitHub Action! You can now invoke cibuildwheel in a GHA build step like:

  - name: Build wheels
    uses: joerick/cibuildwheel@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.

• ✨ Added auto64 and auto32 shortcuts to the CIBW_ARCHS option. (#553)

• ✨ cibuildwheel now prints a list of the wheels built at the end of each run. (#570)

• 📚 Lots of minor docs improvements.

• 🌟 Added support for emulated builds! You can now build manylinux wheels on ARM64aarch64, as well as ppc64le and 's390x'. To build under emulation, register QEMU via binfmt_misc and set the CIBW_ARCHS_LINUX option to the architectures you want to run. See this FAQ entry 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)

2 January 2021

• 🐛 Fix the PyPy virtualenv patch to work on macOS 10.14 (#506)

• 🛠 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 for information on how to use it. We'll be fully updating the docs to this approach in a subsequent release (#494)

• 🛠 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

• 🛠 Update manylinux2010 image to resolve issues with 'yum' repositories (#472)

• ✨ 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)

• ✨ 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)

20 September 2020

• 🛠 Add PPC64LE manylinux image supporting Python 3.9. (#436)

• 📚 Add project URLs to PyPI listing (#428)

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 , 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.

• 🐛 Fix "OSError: [WinError 17] The system cannot move the file to a different disk drive" on GitHub Actions (#388, #389)

24 June 2020

• 🌟 Add CIBW_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)
