Summary

After #1688 bumped requires-python to >=3.10, two cp39 matrix entries were left behind in the cibuildwheel matrix. cibuildwheel refused them with No build identifiers selected, the failure cancelled every other arch in the wheel job (no fail-fast: false on this matrix), and 0.149.0 reached PyPI as sdist + one stray cp314 wheel onlyupload_pypi was skipped because build_wheels didn't complete.

Details

Failing job: Wheels for ubuntu-latest (musllinux) armv7l cp39

##[error]cibuildwheel: No build identifiers selected:
BuildSelector(build_config='cp39*',
              skip_config='cp36-* cp37-* pp36-* pp37-* pp38-* cp38-*',
              requires_python=<SpecifierSet('>=3.10')>,
              enable=frozenset())
##[error]Process completed with exit code 3.

This PR removes the two stale entries:

  • ubuntu-latest qemu=armv7l musl=musllinux pyver=cp39
  • ubuntu-latest qemu=armv7l musl="" pyver=cp39

The fix: prefix lets PSR cut 0.149.1, so the wheel matrix runs once more and upload_pypi publishes a full cross-arch wheel set to replace the sdist-only 0.149.0.

Test plan

  • Merge → confirm PSR releases 0.149.1.
  • Confirm every Wheels for … job completes successfully (no more cancelled arches).
  • Confirm 0.149.1 on PyPI has the full wheel set (manylinux + musllinux x86_64 / aarch64 / armv7l / riscv64, macOS, Windows).

Follow-up worth considering

Add strategy.fail-fast: false to the build_wheels matrix so a single arch failure no longer cancels the other ~30 jobs. Happy to do that in a separate PR if you want.

`pyproject.toml` is now `requires-python = ">=3.10"` after #1688,
so cibuildwheel refused the explicit `CIBW_BUILD=cp39*` matrix entries
with "No build identifiers selected". The cp39 job's failure cancelled
the rest of the wheel matrix (no `fail-fast: false` on the matrix), so
0.149.0 reached PyPI as sdist only. Removing the two stale cp39 entries
lets the next release publish a full wheel set.
