• Build frontends:
  • pip: (fixes merged, waiting for 24.1.0 release) - Upgrade vendored packaging lib pypa/pip#12300
  • build: probably nothing to do, since it depends on latest packaging
• Build backends:
  • meson-python: done modulo adding CI job, see meson-python#499
  • scikit-build-core: fix: free threaded Python scikit-build/scikit-build-core#741
  • setuptools: 69.5.0 upgraded the vendored packaging library to 24.0
• manylinux: feat: add CPython 3.13 --disable-gil build pypa/manylinux#1564
• cibuildwheel: [request] support --disable-gil builds (PEP703) pypa/cibuildwheel#1657 (no macOS installer yet, waiting for 3.13.0b2)
• wheel publishing tools (auditwheel, delvewheel, delocate, repair-wheel): to verify

Thanks @henryiii! Table updated.

Looks like both meson and CMake don't support Windows + free-threading yet, they don't know to look for the library with the "t" for linking. I think I can fix this in scikit-build-core if I can tell it the correct library from sysconfig info.

[rgommers]

Yeah, working on the same thing for Meson. I think adding the t in python313t.lib based on:

bool(sysconfig.get_config_var('Py_GIL_DISABLED'))

should do the job. Plus the debug flavor of it (there's no limited API variant).

Windows free-threaded fixed in scikit-build-core 0.9.5.

FYI, sysconfig's LIBRARY is correct as far as the "t" goes but is .dll instead of .lib.
