| # Three builds per platform, not one per Python version: | |
| # | |
| # cp311 -> a single `cp311-abi3` wheel serving CPython 3.11+, via | |
| # `wheel.py-api` in pyproject.toml. Building it on any | |
| # other version would emit the *same* filename, so only | |
| # the floor version is built. | |
| # cp314t -> free-threaded 3.14. Cannot use abi3: the free-threaded | |
| # cp315t ABI is distinct, and its stable variant (abi3t, PEP 803) | |
| # starts at 3.15 and needs a PEP 793 module export hook | |
| # that Cython does not emit yet. These stay | |
| # version-specific until that lands upstream. | |
| # | |
| # cp313t is deliberately absent: 3.13's free-threaded build was still | |
| # experimental (PEP 703 phase I) with a large single-thread penalty. | |
| # cibuildwheel keeps it behind CIBW_ENABLE: cpython-freethreading. | |
| # | |
| # NOTE: cibuildwheel only tests a wheel on the interpreter that built | |
| # it, so the abi3 wheel is exercised on 3.11 alone here. The | |
| # test_abi3_matrix job below installs it on every supported version. | |
