* Require Python 3.11 in all distributions Every pyproject.toml that declares requires-python now says >= 3.11 and drops the Python 3.10 trove classifier, the tomli build requirement that only existed for 3.10 and the per-version dependency markers for 3.10. Lock files are regenerated. With 3.10 gone, the tomli fallbacks in scripts, dev tooling and tests go too, along with the tomli additional_dependencies of the prek hooks and the blacken-docs py310 target. The tomllib imports that only sat inside functions because of the fallback move to the top of their modules. The four dev/registry and scripts/ci/prek modules left out of the earlier UP017 pass also take their timezone.utc to datetime.UTC fixes here. The minimum host Python checked by check-min-python-version, the default Python of run_generate_constraints.py and the provider cut-off date parsing (fromisoformat, which reads a trailing Z from 3.11) follow the new baseline. ruff infers py311 from the new requires-python, which enables the PEP 646 star-index fix (UP044) applied here and makes two more rules reportable: UP042 (str, Enum to StrEnum) alters what str() and format() return for serialized enum values, and ASYNC109 means dropping the public timeout parameter from async APIs. Both need per-site judgement, so they go on the ignore list with that rationale. The datamodel-codegen target moves to 3.11 too, with use-specialized-enum turned off for the same reason: otherwise the generated Task SDK and airflowctl enums would switch from (str, Enum) to StrEnum. * Drop the Python 3.10 provider metadata shim With provider distributions now requiring Python 3.11, breeze can derive requires-python and classifiers from the default and allowed versions again. The patch-exclusion test and the matching example in MANAGING_PROVIDERS_LIFECYCLE.rst move from 3.10.0 to 3.11.0, the oldest patch release CI still covers. * Keep Breeze's locked dependency versions when dropping Python 3.10 Relocking Breeze for the Python 3.11 baseline ran while recently bumped versions were still inside the 4-day exclude-newer window, so it downgraded pyjwt (reverting #73969), prek, boto3/botocore and filelock. Relocking from the previous lock keeps them and only drops the packages Python 3.11 no longer needs. Generated-by: Claude Opus 5 --------- Co-authored-by: Jarek Potiuk <jarek@potiuk.com>
