v0.15.0

Compare Source

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-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

  later (#​20768)
