Mypy 2.2

We've just uploaded mypy 2.2.0 to the Python Package Index (PyPI). Mypy is a static type checker for Python. This release includes new features, performance improvements and bug fixes. You can install it as follows:

python3 -m pip install -U mypy

You can read the full documentation for this release on Read the Docs.

Support for Closed TypedDicts (PEP 728)

Mypy now supports closed TypedDicts as specified in PEP 728. A closed TypedDict cannot have extra keys beyond those explicitly defined. This allows the type checker to determine that certain operations are safe when they otherwise wouldn't be due to the potential presence of unknown keys.

You can use the closed keyword argument with TypedDict:

HasName = TypedDict("HasName", {"name": str})
HasOnlyName = TypedDict("HasOnlyName", {"name": str}, closed=True)
Movie = TypedDict("Movie", {"name": str, "year": int})
movie: Movie = {"name": "Nimona", "year": 2023}
has_name: HasName = movie  # OK: HasName is open (default)
has_only_name: HasOnlyName = movie  # Error: HasOnlyName is closed and Movie has extra "year" key
</tr></table>

🤖 Claude Code Review

PR Code Review

Summary: This is a single-line dependency version bump in pyproject.toml, updating mypy from 2.3.0 to 2.3.1 in the lint optional-dependencies group (line 78).

Code Quality

• ✅ Style conventions: Change follows the existing pinned-version pattern used throughout the lint list (e.g., flake8==7.3.0).
• ✅ No commented-out code.
• ✅ N/A — no variable names introduced.
• ✅ N/A — single-value change, no duplication introduced.
• ✅ No defects: This is a patch-version bump of a dev/lint tool dependency (pyproject.toml:78). No logic, runtime behavior, or production code paths are affected.
• ✅ .claude/CLAUDE.md reviewed — not touched by this diff and its content is already environment-general.

Testing

• ✅ N/A — dependency version bump with no new functions/endpoints. No tests required.
• ✅ N/A — no new endpoints.
• ✅ N/A — no new logic/edge cases.
• ✅ N/A — coverage threshold unaffected by a dependency pin.

Documentation

• ✅ N/A — no README-relevant behavior change.
• ✅ N/A — no API changes.
• ✅ N/A — no complex logic added.
• ❌ CHANGELOG.md not updated. If this repo maintains a CHANGELOG.md for dependency bumps (many Senzing repos do via automated Dependabot/release-please flows), verify whether this bump should be reflected there or if it's excluded by convention (bot-generated PRs often skip changelog entries by design — check .github/dependabot.yml or release automation config to confirm this is expected).
• ✅ Markdown formatting — N/A, no .md files changed.

Security

• ✅ No hardcoded credentials.
• ✅ N/A — no input handling changed.
• ✅ N/A — no error handling changed.
• ✅ No sensitive data in logs.
• ✅ No .lic files or AQAAAD-prefixed strings present in this diff.

Overall

This is a low-risk, mechanical dependency bump (mypy patch release) with no functional impact. No blocking issues found. The only item worth a quick sanity check is whether CHANGELOG.md should note dependency bumps per this repo's convention — likely not required if these PRs are automated (e.g., Dependabot), consistent with the other recent bump commits visible in git history (wheel, virtualenv, pylint).
