Release Notes

pypa/cibuildwheel (pypa/cibuildwheel)

v2.20.0: Version 2.20.0

Compare Source

• 🌟 CPython 3.13 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 3.13.0rc1, which is guaranteed to be ABI compatible with the final release. Free-threading is still behind a flag/config option. (#​1950)
• ✨ Provide a CIBW_ALLOW_EMPTY environment variable as an alternative to the command line flag. (#​1937)
• 🐛 Don't use uv on PyPy3.8 on Windows, it stopped working starting in 0.2.25. Note that PyPy 3.8 is EoL. (#​1868)
• 🛠 Set the VSCMD_ARG_TGT_ARCH variable based on target arch. (#​1876)
• 🛠 Undo cleaner output on pytest 8-8.2 now that 8.3 is out. (#​1943)
• 📚 Update examples to use Python 3.12 on host (cibuildwheel will require Python 3.11+ on the host machine starting in October 2024) (#​1919)
