• 🌟 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)
