Bumps the python-dependencies group with 3 updates in the / directory: mypy, ruff and ty.

Updates mypy from 2.3.1 to 2.4.0

Mypy Release Notes

Next Release

Mypy 2.4

We've just uploaded mypy 2.4.0 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.

Python 3.15 Support

Mypy 2.4 supports running on Python 3.15 and type checking most Python 3.15 features. This includes the new builtin sentinel type for sentinel values (PEP 661), which mypy now supports (see below for details). Lazy imports (PEP 810) and unpacking in comprehensions (PEP 798) are also supported. Closed TypedDicts (PEP 728) have been supported since mypy 2.2, but the extra_items TypedDict argument, also introduced in PEP 728, is still unsupported. Support for extra_items will be added in a future mypy release.

Native Parser Enabled by Default

Mypy now uses the new native parser by default. It's based on the Ruff parser, and it's significantly faster than the legacy parser, which uses the stdlib ast module. The native parser also has other benefits:

  • You can target newer Python versions and use recent Python syntax even when running mypy on an older Python version. For example, you can use --python-version 3.15 when running mypy on Python 3.14.
  • Stub files can use syntax that is newer than the target Python version. For example, stubs can use the PEP 695 generic class syntax (class Box[T]: ...) when running on or targeting Python 3.10.
  • Parallel type checking requires the native parser.

The legacy parser is still available through --no-native-parser, or native_parser = False in the config file (native_parser = false under [tool.mypy] in pyproject.toml). We are planning to remove the legacy parser in early 2027. If you run into a problem with the native parser, please report it on the issue tracker.

Unlike the legacy parser, the native parser doesn't support type comments for variables defined by for and with statements. These type comments are silently ignored, and the types of the variables are

Updates ty from 0.0.82 to 0.0.84

Release notes

Sourced from ty's releases.

0.0.84

Release Notes

Released on 2026-09-24.

This release addresses GHSA-vxvm-j4xq-q7m4, a use-after-free vulnerability during incremental type checking that can result in arbitrary code execution when analyzing a specially crafted Python project. Users who run ty on untrusted code should upgrade to 0.0.84 or newer.

Bug fixes

  • Fix stale diagnostics from the LSP server after toggling showSyntaxErrors (#28759)

LSP server

  • Complete string keys from dictionary initializers (#28820)
  • Support LSP requests against closed documents (#28595)
  • Select projects for external files using import search paths (#28594)
  • Use workspace editor settings for external files (#28639)

Performance

  • Avoid repeated subtyping checks for materialized recursive protocols (#28774)
  • Skip reading notebooks when discovering scripts (#28781)

Core type checking

  • Avoid incorrect simplification of TypeIs materializations (#28817)
  • Fix disjointness of generic class types (#28787)
  • Fix staticmethod shadowing through generic receivers and unions (#28766)
  • Infer callable signatures from bounded type variables (#28599)
  • Infer constant membership in inline list and set literals (e.g. "foo" in ["foo"] is now inferred as Literal[True]) (#28676)
  • Infer through optional generic containers in the legacy solver (#28791)
  • Preserve call narrowing during cyclic inference (#28708)
  • Preserve intersections of type guard return types (#28796)
  • Use subtyping for constraint-set implication (#28657)

Configuration

  • Disable invalid-legacy-positional-parameter by default (#28834)

Other changes

  • Only consider reachable definitions when determining whether a condition should be exempted from redundant-condition(-strict) due to the condition being defined relative to sys.version_info, sys.platform, os.name or typing.TYPE_CHECKING (#28788)
