Drop Python 3.9 (EOL); require patched pytest 9.x (v2.4.0) - #71
Merged
Conversation
Python 3.9 reached end-of-life on 2025-10-05 and no longer receives CPython security fixes. pytest 9.x already dropped it, which left the 3.9 test environment stuck on pytest 8.4.2 — the version flagged by GHSA-6w46-j5rx-g56g (tmpdir handling), with no fix available for 3.9. Raise the floor to Python 3.10 so every supported runtime resolves to patched pytest 9.x, clearing the advisory. Bump requires-python and the trove classifier, drop 3.9 from the CI matrix and the min-deps job, pin pytest>=9.0.3, and bump the version to 2.4.0.

Summary
Python 3.9 reached end-of-life on 2025-10-05 and no longer receives CPython security fixes. pytest 9.x already dropped 3.9, which left the 3.9 test environment pinned to pytest 8.4.2 — the version flagged by GHSA-6w46-j5rx-g56g (vulnerable tmpdir handling), with no fix available for 3.9 (the patch, 9.0.3, requires Python ≥3.10).
Raising the floor to Python 3.10 makes every supported runtime resolve to patched pytest 9.x, removing the vulnerable pin from
uv.lockand clearing the Dependabot alert.Changes
