+{# Single wheel build tagged cp311-abi3 via SKBUILD_WHEEL_PY_API.
+ The abi3 build must run on Python 3.14: the limited-API build (see
+ python/CMakeLists.txt) requires >= 3.13 dev headers.
+ Freethreading (cp314t/cp315t) wheels are not built: CPython does not
+ support the limited API in free-threaded builds (gh-111506; 3.14t's
Review Comment:
Could we restore the separate full-API free-threaded wheel builds?
`cp311-abi3` wheels do not support free-threaded Python, so removing the
`cp314t`/`cp315t` rows drops coverage rather than consolidating it. Python
3.14t’s Limited API restriction does not prevent building a version-specific
full-API wheel.
To retain those builds, we would need to:
- Make `Py_LIMITED_API=0x030B0000`, the `.abi3.so` suffix, and the
`cp311-abi3` wheel tagging conditional; free-threaded builds should use the
full API and interpreter-specific suffixes/tags.
- Fix the full-API import failure mentioned in the comment, where
assignments such as `KeyValueMetadata.get = Mapping.get` depend on mutable heap
types. Disabling `Py_LIMITED_API` alone will not fix that.
- Restore the free-threaded CI rows and verify imports and tests on those
interpreters.
Most Limited API replacements can remain shared between both build modes.
Also,
[[python/cpython#111506](https://github.com/python/cpython/issues/111506)](https://github.com/python/cpython/issues/111506)
was superseded by Python 3.15’s `abi3t` implementation in
[[python/cpython#146636](https://github.com/python/cpython/issues/146636)](https://github.com/python/cpython/issues/146636).
Migrating to `abi3t` could be a follow-up for 3.15+, but it would not cover
3.14t or be necessary to restore full-API wheels.
