What's new in Pylint 4.0.5?

Release date: 2026-02-20

False Positives Fixed

• Fix possibly-used-before-assignment false positive when using self.fail() in tests.

  Closes #​10743

• Fixed false positive for logging-unsupported-format when no arguments are provided to logging functions.

  According to Python's logging documentation, no formatting is performed when no arguments are supplied, so strings like logging.error("%test") are valid.

  Closes #​10752

• Fix a false positive for invalid-name where a dataclass field typed with Final
  was evaluated against the class_const regex instead of the class_attribute regex.

  Closes #​10790

• Avoid emitting unspecified-encoding (W1514) when py-version is 3.15+.

  Refs #​10791

Other Bug Fixes

• Fix --known_third_party config being ignored.

  Closes #​10801

• Fixed dynamic color mapping for "fail-on" messages when using multiple reporter/output formats.

  Closes #​10825

• dependency on isort is now set to <9, permitting to use isort 8.

  Closes #​10857

Preview features

• Expand the default rule set (#​23385)

  In preview, Ruff now enables a significantly expanded default rule set of 412
  rules, up from the stable default set of 59 rules. The new rules are mostly a
  superset of the stable defaults, with the exception of these rules, which are
  removed from the preview defaults:

  • multiple-imports-on-one-line (E401)
  • module-import-not-at-top-of-file (E402)
  • module-import-not-at-top-of-file (E701)
  • multiple-statements-on-one-line-semicolon (E702)
  • useless-semicolon (E703)
  • none-comparison (E711)
  • true-false-comparison (E712)
  • not-in-test (E713)
  • not-is-test (E714)
  • type-comparison (E721)
  • lambda-assignment (E731)
  • ambiguous-variable-name (E741)
  • ambiguous-class-name (E742)
  • ambiguous-function-name (E743)
  • undefined-local-with-import-star (F403)
  • undefined-local-with-import-star-usage (F405)
  • undefined-local-with-nested-import-star-usage (F406)
  • forward-annotation-syntax-error (F722)

  If you use preview and prefer the old defaults, you can restore them with
  configuration like:

  # ruff.toml
  
  [lint]
  select = ["E4", "E7", "E9", "F"]
  
  # pyproject.toml
  
  [tool.ruff.lint]
  select = ["E4", "E7", "E9", "F"]

  If you do give them a try, feel free to share your feedback in the GitHub
  discussion!
