Release Notes

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!

Release Notes

Released on 2026-02-03.

Check out the blog post for a migration guide and overview of the changes!

Breaking changes

• Ruff now formats your code according to the 2026 style guide. See the formatter section below or in the blog post for a detailed list of changes.

• The linter now supports block suppression comments. For example, to suppress N803 for all parameters in this function:

  # ruff: disable[N803]
  def foo(
      legacyArg1,
      legacyArg2,
      legacyArg3,
      legacyArg4,
  ): ...
  # ruff: enable[N803]

  See the documentation for more details.

• The ruff:alpine Docker image is now based on Alpine 3.23 (up from 3.21).

• The ruff:debian and ruff:debian-slim Docker images are now based on Debian 13 "Trixie" instead of Debian 12 "Bookworm."

• Binaries for the ppc64 (64-bit big-endian PowerPC) architecture are no longer included in our releases. It should still be possible to build Ruff manually for this platform, if needed.

• Ruff now resolves all extended configuration files before falling back on a default Python version.

Stabilization

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

• blocking-http-call-httpx-in-async-function (ASYNC212)
• blocking-path-method-in-async-function (ASYNC240)
• blocking-input-in-async-function (ASYNC250)
• map-without-explicit-strict (B912)
• if-exp-instead-of-or-operator (FURB110)
• single-item-membership-test (FURB171)
• missing-maxsplit-arg (PLC0207)
• unnecessary-lambda (PLW0108)
• unnecessary-empty-iterable-within-deque-call (RUF037)
• in-empty-collection (RUF060)
• legacy-form-pytest-raises (RUF061)
• non-octal-permissions (RUF064)
• invalid-rule-code (RUF102)
• invalid-suppression-comment (RUF103)
• unmatched-suppression-comment (RUF104)
• replace-str-enum (UP042)

The following behaviors have been stabilized:

• The --output-format flag is now respected when running Ruff in --watch mode, and the full output format is now used by default, matching the regular CLI output.
• builtin-attribute-shadowing (A003) now detects the use of shadowed built-in names in additional contexts like decorators, default arguments, and other attribute definitions.
• duplicate-union-member (PYI016) now considers typing.Optional when searching for duplicate union members.
• split-static-string (SIM905) now offers an autofix when the maxsplit argument is provided, even without a sep argument.
• dict-get-with-none-default (SIM910) now applies to more types of key expressions.
• super-call-with-parameters (UP008) now has a safe fix when it will not delete comments.
• unnecessary-default-type-args (UP043) now applies to stub (.pyi) files on Python versions before 3.13.

Formatter

This release introduces the new 2026 style guide, with the following changes:

• Lambda parameters are now kept on the same line and lambda bodies will be parenthesized to let them break across multiple lines (#21385)
• Parentheses around tuples of exceptions in except clauses will now be removed on Python 3.14 and later (#20768)
• A single empty line is now permitted at the beginning of function bodies (#21110)
• Parentheses are avoided for long as captures in match statements (#21176)
• Extra spaces between escaped quotes and ending triple quotes can now be omitted (#17216)
• Blank lines are now enforced before classes with decorators in stub files (#18888)

Preview features

• Apply formatting to Markdown code blocks (#22470, #22990, #22996)

  See the documentation for more details.

Bug fixes

• Fix suppression indentation matching (#22903)

Rule changes

• Customize where the fix_title sub-diagnostic appears (#23044)
• [FastAPI] Add sub-diagnostic explaining why a fix was unavailable (FAST002) (#22565)
• [flake8-annotations] Don't suggest NoReturn for functions raising NotImplementedError (ANN201, ANN202, ANN205, ANN206) (#21311)
• [pyupgrade] Make fix unsafe if it deletes comments (UP017) (#22873)
• [pyupgrade] Make fix unsafe if it deletes comments (UP020) (#22872)
• [pyupgrade] Make fix unsafe if it deletes comments (UP033) (#22871)
