Mypy Release Notes

Next Release

Mypy 2.1

We’ve just uploaded mypy 2.1.0 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.

librt.vecs: Fast Growable Array Type for Mypyc

The new librt.vecs module provides an efficient growable array type vec that is optimized for mypyc use. It provides fast, packed arrays with integer and floating point value types, which can be several times faster than list, and tens of times faster than array.array in code compiled using mypyc. It also supports nested vec objects and non-value-type items, such as vec[vec[str]].

Refer to the documentation for the details.

Contributed by Jukka Lehtosalo.

librt.random: Fast Pseudo-Random Number Generation

The new librt.random module provides fast pseudo-random number generation that is optimized for code compiled using mypyc. It can be 3x to 10x faster than the stdlib random module in compiled code.

Refer to the documentation for the details.

Contributed by Jukka Lehtosalo (PR 21433).

Mypyc Improvements

• Enable incremental self-compilation (Vaggelis Danias, PR 21369)
• Make compilation order with multiple files consistent (Piotr Sawicki, PR 21419)
• Fix crash on accessing StopAsyncIteration (Piotr Sawicki, PR 21406)
• Fix incremental compilation with separate flag (Vaggelis Danias, PR 21299)

Fixes to Crashes

• Fix crash on partial type with --allow-redefinition and global declaration (Jukka Lehtosalo, PR 21428)
• Fix broken awaitable generator patching (Ivan Levkivskyi, PR 21435)

Change: Bumps mypy from 2.0.0 to 2.1.0 in pyproject.toml (line 77).

Code Quality

• ✅ Style guide — Single-line change in a TOML config file; no style concerns.
• ✅ No commented-out code — N/A.
• ✅ Meaningful variable names — N/A.
• ✅ DRY principle — N/A.
• ✅ Defects — No logic errors; straightforward version bump. No version constraint issues (the mypy entry has no Python version selector, applying it to all versions consistently).
• ✅ CLAUDE.md — No changes to project configuration.

Testing

• ✅ Unit/integration tests — Not required for a dependency version bump.
• ✅ Coverage — N/A.

Documentation

• ❌ CHANGELOG.md — No CHANGELOG.md update included. Dependency bumps are typically noted in a changelog entry.
• ✅ README / API docs — No changes needed.
• ✅ Markdown formatting — N/A.

Security

• ✅ No hardcoded credentials — N/A.
• ✅ No license files — N/A.
• ✅ No sensitive data — N/A.

Summary: This is a clean, minimal dependency bump. The only actionable finding is the missing CHANGELOG.md entry. Otherwise, no issues.

Code Review

PR Summary: Dependency bump — mypy from 2.0.0 → 2.1.0 in pyproject.toml (line 77).

---

Code Quality

• ✅ Style guide — Single-line change in a TOML config file; no style concerns.
• ✅ No commented-out code — Not applicable.
• ✅ Meaningful variable names — Not applicable.
• ✅ DRY principle — mypy has a single unpinned entry (no Python-version split like other tools). No duplication introduced.
• ✅ Defects / bugs / edge cases — No logic changes. The bump is a minor version increment (2.0.0 → 2.1.0); mypy minor versions can introduce new type errors in existing code, but that risk is mitigated by CI running mypy on all supported Python versions.
• ✅ CLAUDE.md — No changes to .claude/CLAUDE.md; nothing project-config-specific to flag.

Testing

• ✅ Unit/integration tests — No new logic; no tests required for a dependency bump.
• ✅ Test coverage — Not applicable.

Documentation

• ✅ README — No update needed.
• ❌ CHANGELOG.md — A dependency bump should be recorded in the changelog. No CHANGELOG entry was included in this diff. This is a minor issue but worth noting for traceability.
• ✅ Inline comments — Not applicable.
• ✅ Markdown formatting — Not applicable.

Security

• ✅ No hardcoded credentials — None present.
• ✅ Input validation — Not applicable.
• ✅ Error handling — Not applicable.
• ✅ No sensitive data in logs — Not applicable.
• ✅ No license files (.lic / AQAAAD) — None present.

Summary: This is a clean, minimal dependency bump. The only actionable finding is a missing CHANGELOG entry. Everything else looks good.
