v0.15.2

Compare Source

Released on 2026-02-19.

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!
