Breaking changes

• Several rules can now add from __future__ import annotations automatically

  TC001, TC002, TC003, RUF013, and UP037 now add from __future__ import annotations as part of their fixes when the lint.future-annotations setting is enabled. This allows the rules to move more imports into TYPE_CHECKING blocks (TC001, TC002, and TC003), use PEP 604 union syntax on Python versions before 3.10 (RUF013), and unquote more annotations (UP037).

• Full module paths are now used to verify first-party modules

  Ruff now checks that the full path to a module exists on disk before categorizing it as a first-party import. This change makes first-party import detection more accurate, helping to avoid false positives on local directories with the same name as a third-party dependency, for example. See the FAQ section on import categorization for more details.

• Deprecated rules must now be selected by exact rule code

  Ruff will no longer activate deprecated rules selected by their group name or prefix. As noted below, the two remaining deprecated rules were also removed in this release, so this won't affect any current rules, but it will still affect any deprecations in the future.

• The deprecated macOS configuration directory fallback has been removed

  Ruff will no longer look for a user-level configuration file at ~/Library/Application Support/ruff/ruff.toml on macOS. This feature was deprecated in v0.5 in favor of using the XDG specification (usually resolving to ~/.config/ruff/ruff.toml), like on Linux. The fallback and accompanying deprecation warning have now been removed.

Removed Rules

The following rules have been removed:

• pandas-df-variable-name (PD901)
• non-pep604-isinstance (UP038)

The following rules have been stabilized and are no longer in preview:

• airflow-dag-no-schedule-argument (AIR002)
• airflow3-removal (AIR301)
• airflow3-moved-to-provider (AIR302)
• airflow3-suggested-update (AIR311)
• airflow3-suggested-to-move-to-provider (AIR312)
• long-sleep-not-forever (ASYNC116)
• f-string-number-format (FURB116)
• os-symlink (PTH211)
• generic-not-last-base-class (PYI059)
• redundant-none-literal (PYI061)
• pytest-raises-ambiguous-pattern (RUF043)
• unused-unpacked-variable (RUF059)

Mypy Release Notes

Next Release

Mypy 1.18

We’ve just uploaded mypy 1.18 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.

Mypy Performance Improvements

Mypy 1.18 includes numerous performance improvements, resulting in about 40% speedup compared to 1.17 when type checking mypy itself. In extreme cases, the improvement can be 10x or higher. The list below is an overview of the various mypy optimizations. Many mypyc improvements (discussed in a separate section below) also improve performance.

Type caching optimizations have a small risk of causing regressions. When reporting issues with unexpected inferred types, please also check if --disable-expression-cache will work around the issue, as it turns off some of these optimizations.

• Improve self check performance by 1.8% (Jukka Lehtosalo, PR 19768, 19769, 19770)
• Optimize fixed-format deserialization (Ivan Levkivskyi, PR 19765)
• Use macros to optimize fixed-format deserialization (Ivan Levkivskyi, PR 19757)
• Two additional micro‑optimizations (Ivan Levkivskyi, PR 19627)
• Another set of micro‑optimizations (Ivan Levkivskyi, PR 19633)
• Cache common types (Ivan Levkivskyi, PR 19621)
• Skip more method bodies in third‑party libraries for speed (Ivan Levkivskyi, PR 19586)
• Simplify the representation of callable types (Ivan Levkivskyi, PR 19580)
• Add cache for types of some expressions (Ivan Levkivskyi, PR 19505)
• Use cache for dictionary expressions (Ivan Levkivskyi, PR 19536)
• Use cache for binary operations (Ivan Levkivskyi, PR 19523)
• Cache types of type objects (Ivan Levkivskyi, PR 19514)
• Avoid duplicate work when checking boolean operations (Ivan Levkivskyi, PR 19515)
• Optimize generic inference passes (Ivan Levkivskyi, PR 19501)
• Speed up the default plugin (Jukka Lehtosalo, PRs 19385 and 19462)
• Remove nested imports from the default plugin (Ivan Levkivskyi, PR 19388)
• Micro‑optimize type expansion (Jukka Lehtosalo, PR 19461)
• Micro‑optimize type indirection (Jukka Lehtosalo, PR 19460)
• Micro‑optimize the plugin framework (Jukka Lehtosalo, PR 19464)
• Avoid temporary set creation in subtype checking (Jukka Lehtosalo, PR 19463)
• Subtype checking micro‑optimization (Jukka Lehtosalo, PR 19384)
• Return early where possible in subtype check (Stanislav Terliakov, PR 19400)
• Deduplicate some types before joining (Stanislav Terliakov, PR 19409)
• Speed up type checking by caching argument inference context (Jukka Lehtosalo, PR 19323)

v1.13.0

New Features 🌈🔗

• New audit: undocumented-permissions detects explicit permission grants that lack an explanatory comment (#1131)

  Many thanks to @​johnbillion for proposing and implementing this audit!

Enhancements 🌱🔗

• zizmor's configuration discovery behavior has been significantly refactored, making it easier to audit multiple independent inputs with their own configuration files (#1094)

  For most users, this change should cause no compatibility issues. For example, the following commands will continue to load the same configuration files as before:

  zizmor .
  zizmor .github/
  

  For other users, the behavior will change, but in a way that's intended to correct a long-standing bug with configuration discovery. In particular, the following commands will now behave differently:

  # OLD: would discover config in $CWD
  # NEW: will discover two different configs, one in each of the repos
  zizmor ./repoA ./repoB
  

  Separately from these changes, zizmor continues to support --config <path> and ZIZMOR_CONFIG with the exact same behavior as before.

  See Configuration - Discovery for a detailed explanation of the new behavior.

• Audit rules can now be disabled entirely in zizmor's configuration. See rules..disable for details (#1132)

• The obfuscation audit now supports auto-fixes for many findings (#1088)

Bug Fixes 🐛🔗

• zizmor now correctly honors --strict-collection when collecting from remote inputs. This also means that the default collection strictness has changed for remote inputs to match all other inputs (#1122)

• Fixed a bug where zizmor would crash on certain UTF-8 inputs lacking an explicit final newline due to a bug in the annotate-snippets crate (#1136)
