ci: build CPython 3.14 wheels (bump cibuildwheel to 4.x)#730
Merged
Conversation
The release wheel job pinned pypa/cibuildwheel@v2.21.3 (Oct 2024), which predates CPython 3.14. cibuildwheel only builds the interpreters its own release knows about, so `build = "cp3*"` expanded to at most cp313 and no 3.14 wheels were ever produced or uploaded to PyPI for 0.12.0/0.12.1 -- a local install on 3.14 has to compile from the sdist (issue #715). The test matrix separately tests 3.14 via setup-python, which is why the gap only showed up in the published wheels. Bump the action to v4.1.0, which builds CPython 3.14 by default (since cibuildwheel 3.1) and still supports cp310-cp313. Because free-threading is no longer experimental in 3.14, cibuildwheel would now also build free-threaded (cp314t) wheels by default; the Cython extension has not been validated under a no-GIL interpreter, so skip `cp31?t-*` for now. Verified with `cibuildwheel --print-build-identifiers` that the linux build set is now cp310..cp314 manylinux_x86_64 (no cp314t, no musllinux). The manylinux2014 image shorthand and the existing build/skip/archs/before-build options remain valid in 4.x.

Description
Fixes #715. Re-opens #718 onto
master— #718 was merged into its stale stacked-parent branch (claude/ci-confluent-driver-matrix) instead ofmaster, so its content never reachedmaster. This branch is the same commit cherry-picked directly ontomaster, independent of any chain.No CPython 3.14 wheels were published for 0.12.0/0.12.1, so installing on 3.14 forces a source build.
Root cause
The release
build_wheelsjob pinnedpypa/cibuildwheel@v2.21.3(Oct 2024), which predates CPython 3.14. cibuildwheel only builds the interpreters its own release knows about, sobuild = "cp3*"expanded to at mostcp313— nocp314wheels were produced.Fix
pypa/cibuildwheel@v4.1.0, which builds CPython 3.14 by default and still supports cp310–cp313.cp31?t-*toskip, since 4.x would otherwise build free-threaded (cp314t) wheels and faust's Cython extension hasn't been validated under a no-GIL interpreter.Verification
cibuildwheel --print-build-identifiers --platform linuxnow lists cp310–cp314 manylinux, withcp314tand musllinux correctly excluded. Wheels are only produced on arelease: createdevent, so this takes effect on the next tagged release.🤖 Generated with Claude Code
