Why

Dependabot reports 17 advisories on filelock 4.1.0 in uv.lock (1 high, 12 medium, 4 low). All are fixed in filelock 4.2.1.

filelock 4.1.1 and later need Python 3.11, so as long as the hooks support Python 3.10, uv.lock has to keep filelock 4.1.0 for 3.10 and the alerts stay open. Python 3.10 reached end of life in October 2026.

What changes

• requires-python = ">=3.11"; the 3.10 classifier and the 3.10 CI job are removed.
• filelock>=4.2.1 instead of >=3.16.
• uv.lock pins filelock 4.2.4, the newest release older than the 7-day Dependabot cooldown. tomli, exceptiongroup and typing-extensions drop out (3.10 only).
• AGENTS.md, CONTRIBUTING.md and the _install_lock docstring no longer mention Python 3.10 or filelock 3.x.

Impact

The hooks only use FileLock to serialize installs. Most of the advisories are in ReadWriteLock, SoftReadWriteLock and StrictSoftFileLock, which the hooks do not use. The rest need another local user with write access to the pre-commit environment directory. Users on Python 3.11+ already got a fixed filelock, because the dependency was not capped.

Users still on Python 3.10 can keep using the current release.

Testing

• 398 tests pass on Python 3.11 and 3.13, coverage 100%.
• An OSV scan of the new uv.lock finds no known vulnerabilities.

Summary by CodeRabbit

• Compatibility
  • Python 3.10 is no longer supported. Python 3.11 or newer is now required.
  • Automated tests run on Python 3.11 through 3.15.
• Documentation
  • Updated project setup and support information to reflect the Python version requirement.

Walkthrough

The project now requires Python 3.11 or newer, and its test matrix starts at Python 3.11. The minimum filelock version is now 4.2.1, and the _install_lock documentation has been updated.

Changes

Compatibility updates

Layer / File(s)	Summary
Python support range pyproject.toml, .github/workflows/test.yml, AGENTS.md, CONTRIBUTING.md	The minimum supported Python version changes from 3.10 to 3.11. The Python 3.10 classifier and test matrix entry are removed. The support and setup documentation now states the updated minimum and tested range.
Filelock requirement and lock documentation pyproject.toml, cpp_linter_hooks/util.py	The minimum filelock version changes from 3.16 to 4.2.1. The _install_lock documentation removes its statement about the unlocked fallback for filelock 3.x and retains the stale-lock-file case.

Full details: Title check

Explanation

The title "build: drop Python 3.10 and require filelock 4.2.1" matches the main changes. The raw summary and objectives show the minimum Python version moves from 3.10 to 3.11, the 3.10 classifier and CI matrix entry are removed, and the filelock minimum rises from 3.16 to 4.2.1. The title is specific, concise, and follows the conventional commit style. It omits the docs cleanup and the removal of tomli, exceptiongroup, and typing-extensions, which is acceptable because a title does not need every detail.

Full details: Docstring Coverage

Explanation

Docstring coverage is 100.00% which is sufficient. The required threshold is 80.00%. Docstring coverage is scoped to functions touched by this diff with cyclomatic complexity of at least 2. Documentation-only edits and deletions within surviving functions are included; unchanged diff context and fully deleted functions are excluded. Analyzed 1 functions across 1 files. (4 skipped: 4 unsupported.)
