#497) Consolidates all open Renovate deps/chore PRs into one change, fixes the CI breakage on `main`, and moves the supported Python range to 3.10–3.14. ## Why main was red The weekly runs on `main` have been failing on Python 3.10+ since early June. Root cause: **typer ≥0.26 vendors click** and no longer depends on it, so fresh installs stopped pulling click in — while gto imports `click` directly (`gto/cli.py`, `gto/utils.py`, `tests/conftest.py`) without declaring it. pylint failed with `E0401: Unable to import 'click'`. It's worse than lint: gto's CLI machinery subclasses real-click classes (`GtoCliMixin(click.Command)`, `@click.pass_context`) and mixes them into typer's (now vendored-click) `TyperCommand`/`TyperGroup` MROs. With typer 0.26.x even `gto --help` crashes on startup (`TypeError: Command.__init__() got an unexpected keyword argument 'rich_markup_mode'`) — i.e. a fresh `pip install gto` on Python 3.10+ currently yields a broken CLI. Python 3.9 was unaffected only because it resolves typer 0.23.2 (0.24+ requires Python ≥3.10; all pre-0.26 versions depend on real click). **Fix:** declare `click>=8,<9` explicitly and pin `typer>=0.4.1,<0.26`. Migrating to vendored-click typer (≥0.26) requires reworking the CLI help/exception machinery against `typer._click` and should be tracked as a separate effort. ## Python support - Drop Python 3.9 (EOL October 2025): removed from test matrix, classifiers; `requires-python = ">=3.10"` - Add Python 3.14 to the test matrix and classifiers - Remove the `CliRunner` `mix_stderr` shim in `tests/conftest.py` (only needed for the old click that py3.9 resolved) - `zip(..., strict=False)` fixes auto-applied by ruff `B905`, which activates with the 3.10+ target ## Consolidated Renovate updates | PR | Update | Resolution | |---|---|---| | #496 | `actions/checkout` v5 → v7 | taken as-is | | #493 | `codecov/codecov-action` v4 → v7 | taken as-is | | #484 | deploy job Python 3.13 → 3.14 | taken, plus 3.14 in test matrix | | #487 | pylint 3.3.8 → 4.0.6 | taken (pylint 4 requires ≥3.10 — unblocked by the 3.9 drop) | | #482 | pylint → 3.3.9 | superseded by #487 | | #495 | mypy → v2 | delivered as `mypy==2.2.0` (the py3.9-only `<1.11.0` pin is gone with 3.9) | | #494 | mypy → `<1.20.3` | superseded by #495 | ## Verification Ran locally on macOS for Python **3.10**, **3.13**, and **3.14**, each with a fresh venv: - `pip install -e .[dev]` resolves cleanly (click 8.4.2, typer 0.23.2, mypy 2.2.0, pylint 4.0.6, pygit2 1.19.3) - `pre-commit run --all-files` — all hooks pass (ruff, ruff-format, mypy 2.2.0, pylint 4.0.6) - `pytest` — 165 passed on each - `gto --help` / `gto show` / `gto --version` work (broken before on 3.10+ with unpinned typer) - `python -m build && twine check --strict dist/*` passes on 3.14 (deploy job path) 🤖 Generated with [Claude Code](https://claude.com/claude-code) --------- Co-authored-by: Claude Fable 5 <noreply@anthropic.com>
