v0.17.0

Compare Source

Released on 2026-10-09.

The executables in our macOS and Windows release archives and ruff wheels are now code-signed.
macOS executables are signed with an Apple Developer ID certificate and notarized by Apple. Windows
executables have timestamped Authenticode signatures from Azure Artifact Signing. This enables
verification of the release publisher and binary integrity, supports publisher-based allowlisting,
and should reduce security warnings and antivirus false positives.

Breaking changes

• Update the default and latest Python versions for 3.15 (#​28792)

  Ruff now defaults to Python 3.11 instead of 3.10 when no Python version is configured through
  target-version or
  requires-python. When
  checking for syntax errors without a configured Python version, Ruff now defaults to Python 3.15
  instead of 3.14.

• Update the default rule set (#​28786)

  Several of the flake8-datetimez rules
  (DTZ001,
  DTZ005,
  DTZ006,
  DTZ007,
  DTZ011,
  DTZ012, and
  DTZ901) are no longer enabled by default,
  while undefined-local-with-nested-import-star-usage
  (F406), which corresponds to a syntax error, is now enabled by default.

• Update Rust crate quick-junit to 0.8.0 (#​27295)

  JUnit output now uses a skipped attribute instead of disabled on <testsuite> elements and
  includes a skipped attribute on the root <testsuites> element.

• [flake8-import-conventions] Add datetime as dt as a conventional alias (ICN001) (#​28790)

• Support Unicode dummy variable names (#​28722)

  The default lint.dummy-variable-rgx
  now recognizes underscore-prefixed Unicode names, such as _次, as dummy variables.

• Update to Unicode 17 (#​21229, #​28784)

  Ruff now uses Unicode 17 data for identifier normalization and named character escapes ("\N{...}").

• Always show unsafe and display-only fixes in the CLI (#​27810)

  The default full output format now shows unsafe fixes and suggestions requiring manual review,
  regardless of the unsafe-fixes setting.
  Actually applying unsafe fixes still requires explicit opt-in.

• Remove the Python dependency from conda-forge builds (conda-forge/ruff-feedstock#361)

  The conda-forge build no longer depends on Python, now supports linux-riscv64, win-arm64, and
  linux-ppc64le platforms, and now includes shell completions. However, no longer depending on
  Python means that python -m ruff and import ruff will no longer work. Use ruff directly from
  PATH instead. PyPI installations and those from the standalone installer are unaffected.

• Remove support for ruff-lsp (#​28750)

  Support for ruff-lsp, the legacy Python language server deprecated in Ruff
  v0.9.5, has been removed. The Ruff VS Code
  extension now always uses the native language server; ruff.nativeServer is deprecated and
  ignored. See the migration guide.

Stabilization

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

• lazy-import-mismatch (TID254)
• lazy-import-immediately-resolved
  (TID255)
• os-path-commonprefix (RUF071)

The following behaviors have been stabilized:

• The formatter, unsorted-imports (I001),
  line-too-long (E501), and
  doc-line-too-long (W505) now
  consistently ignore trailing pragma comments when computing line length. This resolved several
  bugs involving interactions between these rules
  (#​27313) but may also cause existing imports to be
  reformatted and was thus classified as a breaking change.

Preview features

• [refurb] Mark fix unsafe and move to suspicious (FURB152) (#​28405)

• [flake8-self] Allow private access on object.__new__(cls) instances (SLF001) (#​29001)

• [flake8-type-checking] Add the notion of runtime-ambiguous references (#​26508)
