Raises the minimum Python to 3.11 now that 3.10 has reached end of life; users still on 3.10 keep installing the current release, since pip picks the newest version whose requires-python matches.

-requires-python = ">=3.10"
+requires-python = ">=3.11"
  • Removes 3.10 from the test matrix and wheel builds, and moves the PyPy lane from pypy-3.10 to pypy-3.11.
  • Drops the 3.10 compatibility code: the sys.version_info >= (3, 11) check in wait_future_or_timeout, and the backports-asyncio-runner, exceptiongroup and tomli entries in poetry.lock.
  • Same shape as the 3.9 drop in feat: drop Python 3.9 support #1688.
All changes
  • pyproject.toml: requires-python = ">=3.11", poetry python = "^3.11", ruff target-version = "py311". Removes the PYI034 ignore (it was waiting for this drop) and ignores ASYNC109, which the py311 target turns on: it flags the timeout parameters on public async APIs such as async_get_service_info and async_wait, and renaming them would break callers.
  • PYI034 fixes: Zeroconf.__enter__, ServiceBrowser.__enter__, AsyncServiceBrowser.__aenter__ and AsyncZeroconf.__aenter__ now return typing.Self.
  • .pre-commit-config.yaml: pyupgrade --py311-plus. It made no further rewrites.
  • ci.yml: drops 3.10 from test; changes pypy-3.10 to pypy-3.11 (matrix entry and two excludes); removes the two cp310 armv7l QEMU lanes; adds cp310-* pp310-* to CIBW_SKIP.
  • README.rst, CLAUDE.md, the pr-workflow skill and two comments in tests/conftest.py: version references updated.
  • poetry.lock: regenerated. It only drops the three 3.10-only backports; no other versions change.

Test plan

  • pre-commit run --all-files passes.
  • Full suite with every TO_CYTHONIZE module compiled on CPython 3.11 (523 passed) and 3.14 (523 passed).
  • CI matrix passes, including the new pypy-3.11 lane.
