- PyO3 0.22 -> 0.28 (allow_threads -> detach, pyclass skip_from_py_object);
builds natively on Python 3.14 with no forward-compat flag. Add 3.14 to the
CI test matrix, the release wheel matrix, and pyproject classifiers.
- Confidence: MonthName and MonthNameShort now share a vote bucket, so "May"
(a 3-letter name tokenized as short-form) no longer lowers confidence on
"%d %B %Y" data. The format was already correct; only the score dipped.
- CI/release: bump actions/checkout v4->v5, actions/setup-python v5->v6,
actions/{upload,download}-artifact v4->v5 (Node 20 runtime retirement);
Rust toolchain pin 1.81 -> 1.83 (PyO3 0.28 MSRV). Artifact upload/download
kept on the same major for guaranteed interop on the publish path.
Verified locally: 89 Rust tests (cargo test --lib), clippy --all-features
-D warnings clean, native Python 3.14 build + 42 pytest green.
