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

Code Review: Bump mypy 2.3.0 → 2.3.1

This is a single-line dependency version bump in pyproject.toml:57. Given the minimal scope, most checklist categories are not applicable.

Code Quality

• ✅ Style conventions: Change follows existing pyproject.toml formatting (matches surrounding pinned-version entries).
• ✅ No commented-out code: N/A, none present.
• ✅ Meaningful variable names: N/A, no code changed.
• ✅ DRY principle: N/A.
• ✅ Defects: No logic changed. This is a patch-version bump (2.3.0 → 2.3.1), low risk of breaking changes. One note: mypy is unpinned relative to Python version elsewhere in this same file (unlike isort/pylint which have python_version markers), but that's pre-existing and not introduced by this diff.
• ✅ CLAUDE.md review: .claude/CLAUDE.md is unchanged by this diff. Existing content is generic (build commands, env vars, conventions) and not tied to a specific local developer's machine — no issue found.

Testing

• N/A — dependency version bump only, no new functions/endpoints. Recommend confirming CI (lint job running mypy python/) passes with 2.3.1 before merge, since mypy releases occasionally introduce new checks/errors on unchanged code.

Documentation

• ✅ N/A — no README/API docs/CHANGELOG expected for a routine dependency bump (appears to be an automated Dependabot-style PR based on commit history).

Security

• ✅ No hardcoded credentials, no input validation/error handling/logging concerns applicable.
• ✅ No .lic files or AQAAAD-prefixed strings present in this diff.

Summary

No blocking issues. This is a low-risk, routine dependency bump. Recommendation: Approve, contingent on CI (mypy lint step) passing.
