20241206

This release includes a fix for 20241205, please see that release for other changes.

Fixes

• Create a copy of python3.13t.exe at python.exe and pythonw3.13t.exe at pythonw.exe for free-threaded Windows distributions: 20241205 attempted to remove the 3.13t suffixed executables, but it caused a regression with the virtual environment launcher. A later release may consolidate these executables under unsuffixed name for consistency. In the meantime, a copy is a simple, compatible solution.

20241205

This release includes a regression for free-threaded Python 3.13 on Windows. No other distribution versions are affected. The regression is resolved in 20241206 See #405 for details.

Breaking

• Drop support for Python 3.8: The 20241008 release was the last release with Python 3.8 distributions. Support has now been removed from the build process.
• Rename python3.13t.exe to python.exe in Windows free-threaded distributions: This matches the other Windows distributions. See astral-sh/uv#8298 for discussion.

Upgrades

Full Changelog: 2024100...2024101

20241008

Upgrades

• CPython 3.13.0rc3 -> CPython 3.13.0 (final)

Changes

• New builds of CPython 3.13 with the experimental freethreading feature are published. Distributions with the following new build options are available:

  • freethreaded+debug
  • freethreaded+pgo+lto
  • freethreaded+pgo
  • freethreaded+lto
  • freethreaded+noopt

  Note that not all build options are available for every platform. Notably excluded are freethreaded builds for musl Linux distributions, which need further development. The freethreaded tag will be present in the new build_options field of the PYTHON.json metadata.

• The CPython 3.8 builds are no longer published. Following the release of CPython 3.13, CPython 3.8 is officially EOL and no more versions will be released upstream.

20241002

Upgrades

• CPython 3.12.6 -> 3.12.7
• CPython 3.13.0rc2 -> 3.13.0rc3

Other

• The PYTHON.json metadata version has been bumped from 7 to 8. The new version includes a build_options field which will eventually replace the optimizations field. The build_options field contains tags in the same format as the optimizations field. In this release, the contents are identical to the optimizations field, but in a future release, it will contain additional build options such as a freethreaded tag. The optimizations field is deprecated and will be removed in a future release. In the meantime, it will exclude any new tags added to the build_options field that are not related to performance optimizations.

Upgrades

• LLVM 17.0.6 -> 18.0.8

Enhancements

• A new install_only_stripped variant is now included in the release (#279). These builds are constructed by taking the install_only variant for each platform and stripping any debug symbols. The resulting builds are significantly smaller, especially on Windows and Linux, but omit debugging symbols. The install_only builds continue to preserve such symbols.

Full Changelog: 2024071...2024072

20240725

This release was yanked as it lacks the install_only variants.
