v2.17.0

• 🌟 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 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.
• ✨ 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

• 🐛 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

🛠 Update manylinux pins to upgrade from a problematic PyPy version. (#1737)

v2.16.3

• 🐛 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.
• 📚 A lot of docs improvements! (#1708, #1705, #1686, #1679, #1667, #1665)

v2.16.2

• 🛠 Updates CPython 3.12 version to 3.12.0, final release (#1635)
• ✨ Adds a debug option 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 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

• 🛠 Updates the prerelease CPython 3.12 version to 3.12.0rc3 (#1625)
• 🛠 Only calls linux32 in containers when necessary (#1599)

v2.16.0

• ✨ Add the ability to pass additional flags to a build frontend through the CIBW_BUILD_FRONTEND option (#1588).
• ✨ The environment variable SOURCE_DATE_EPOCH is now automatically passed through to container Linux builds (useful for reproducible builds!) (#1589)
• 🛠 Updates the prerelease CPython 3.12 version to 3.12.0rc2 (#1604)
• 🐛 Fix requires_python auto-detection from setup.py when the call to setup() is within an if __name__ == "__main__" block (#1613)
• 🐛 Fix a bug that prevented building Linux wheels in Docker on a Windows host (#1573)
• 🐛 --only can now select prerelease-pythons (#1564)
• 📚 Docs & examples updates (#1582, #1593, #1598, #1615)

v2.15.0

• 🌟 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)

v2.14.1

• 🛠 Updates the prerelease CPython 3.12 version to 3.12.0b4 (#1550)

v2.14.0

• ✨ 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)
