Release Notes

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!

0.26.0

• When using assert_all_requests_are_fired=True, assertions about unfired requests are now raised even when an exception occurs in the context manager or decorated function. Previously, these assertions were suppressed when exceptions occurred. This new behavior provides valuable debugging context about which mocked requests were or weren't called.
• Consider the Retry-After header when handling retries
