Release Notes

pypa/cibuildwheel (cibuildwheel)

v2.21.2

Compare Source

• ✨ Adds support for building 32-bit armv7l wheels on musllinux. On a Linux system with emulation set up, set CIBW_ARCHS to armv7l 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 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)

v2.21.1: Version 2.21.1

Compare Source

• 🐛 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)

v2.21.0: Version 2.21.0

Compare Source

• ⚠️ 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. (#​1961)
