Cibuildwheel

_1 March 2025_

- ✨ Adds official support for the new GitHub Actions Arm runners. In fact these worked out-of-the-box, now we include them in our tests and example configs. (2135 via 2281)
- ✨ Adds support for building PyPy 3.11 wheels (2268 via 2281)
- 🛠 Adopts the beta pypa/manylinux image for armv7l builds (2269 via 2281)
- 🛠 Dependency updates, including Pyodide 0.27 (2117 and 2281)

_23 November 2024_

- 🌟 Added a new `CIBW_ENABLE`/`enable` feature that replaces `CIBW_FREETHREADED_SUPPORT`/`free-threaded-support` and `CIBW_PRERELEASE_PYTHONS` with a system that supports both. In cibuildwheel 3, this will also include a PyPy setting and the deprecated options will be removed. (2048)
- 🌟 [Dependency groups](https://peps.python.org/pep-0735/) are now supported for tests. Use `CIBW_TEST_GROUPS`/`test-groups` to specify groups in `[dependency-groups]` for testing. (#2063)
- 🌟 Support for the experimental Ubuntu-based ARMv7l manylinux image (2052)
- ✨ Show a warning when cibuildwheel is run from Python 3.10 or older; cibuildwheel 3.0 will require Python 3.11 or newer as host (2050)
- 🐛 Fix issue with stderr interfering with checking the docker version (2074)
- 🛠 Python 3.9 is now used in `CIBW_BEFORE_ALL`/`before-all` on linux, replacing 3.8, which is now EoL (2043)
- 🛠 Error messages for producing a pure-Python wheel are slightly more informative (2044)
- 🛠 Better error when `uname -m` fails on ARM (2049)
- 🛠 Better error when repair fails and docs for abi3audit on Windows (2058)
- 🛠 Better error when `manylinux-interpreters ensure` fails (2066)
- 🛠 Update Pyodide to 0.26.4, and adapt to the unbundled pyodide-build (now 0.29) (2090)
- 🛠 Now cibuildwheel uses dependency-groups for development dependencies (2064, 2085)
- 📚 Docs updates and tidy ups (2061, 2067, 2072)

_9 October 2024_

- 🛠 Update CPython 3.13 to 3.13.0 final release (2032)
- 📚 Docs updates and tidy ups (2035)

_2 October 2024_

- ✨ Adds support for building 32-bit armv7l wheels on musllinux. On a Linux system with emulation set up, set [CIBW_ARCHS](https://cibuildwheel.pypa.io/en/stable/options/#archs) to `armv7l` on Linux to try it out if you're interested! (2017)
- 🐛 Fix Linux Podman builds on some systems (2016)
- ✨ Adds official support for running on Python 3.13 (2026)
- 🛠 Update CPython 3.13 to 3.13.0rc3 (2029)

Note: the default [manylinux image](https://cibuildwheel.pypa.io/en/stable/options/#linux-image) is **scheduled to change** from `manylinux2014` to `manylinux_2_28` in a cibuildwheel release on or after **6th May 2025** - you can set the value now to avoid getting upgraded if you want. (1992)

_16 September 2024_

- 🐛 Fix a bug in the Linux build, where files copied to the container would have invalid ownership permissions (2007)
- 🐛 Fix a bug on Windows where cibuildwheel would call upon `uv` to install dependencies for versions of CPython that it does not support (2005)
- 🐛 Fix a bug where `uv 0.4.10` would not use the right Python when testing on Linux. (2008)
- 🛠 Bump our documentation pins, fixes an issue with a missing package (2011)

_13 September 2024_

- ⚠️ Update CPython 3.12 to 3.12.6, which changes the macOS minimum deployment target on CPython 3.12 from macOS 10.9 to macOS 10.13 (1998)
- 🛠 Changes the behaviour when inheriting `config-settings` in TOML overrides - rather than extending each key, which is rarely useful, individual keys will override previously set values. (1803)
- 🛠 Update CPython 3.13 to 3.13.0rc2 (1998)
- ✨ Adds support for multiarch OCI images (1961)
- 🐛 Fixes some bugs building Linux wheels on macOS. (1961)
- ⚠️ Changes the minimum version of Docker/Podman to Docker API version 1.43, Podman API version 3. The only mainstream runner this should affect is Travis Graviton2 runners - if so you can [upgrade your version of Docker](https://github.com/pypa/cibuildwheel/pull/1961#issuecomment-2304060019).
