v0.16.0

Compare Source

Released on 2026-07-23.

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

Breaking changes

• Ruff now enables a much larger set of rules by default (413, up from 59). See the blog post for
  more details and the new Default Rules page for a
  full listing of the enabled rules. Note that this is primarily an expansion, but 18 of the more
  opinionated pycodestyle (E) and pyflakes (F) rules have been removed from the default set:
  E401, E402, E701, E702, E703, E711, E712, E713, E714, E721, E731, E741,
  E742, E743, F403, F405, F406, and F722.

• Ruff can now format Python code blocks in Markdown files and will do this by default. See the
  documentation for more details.

• Ruff now supports ruff: ignore comments at the ends of lines, like noqa comments, or on the line preceding a diagnostic. For example, these both suppress an unused-import (F401) diagnostic:

  import math  # ruff: ignore[F401]
  
  # ruff: ignore[F401]
  import os

• Fixes are now shown in check and format --check output:

  ❯ ruff format --check .
  unformatted: File would be reformatted
   --> try.md:1:1
    |
  1 | ```python
    - import   math
  2 + import math
  3 | ```
    |
  
  1 file would be reformatted

  This example also shows off the Markdown formatting.

• format --check now supports the same output formats as the linter, including the github and
  gitlab outputs for rendering annotations in CI:

  ❯ ruff format --check --output-format github .
  ::error title=ruff (unformatted),file=try.md,line=2,col=8,endLine=2,endColumn=10::try.md:2:8: unformatted: File would be reformatted

  See the CLI help or documentation for the
  full list of supported formats.

• The filename, location, end_location, fix.edits[].location, and fix.edits[].end_location
  fields in the JSON output format may now be null rather than defaulting to the empty string and
  row 1, column 1, respectively.

Stabilization

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

• airflow3-incompatible-function-signature
  (AIR303)
• missing-copyright-notice
  (CPY001)
• unnecessary-from-float (FURB164)
• sorted-min-max (FURB192)
• implicit-string-concatenation-in-collection-literal
  (ISC004)
• log-exception-outside-except-handler
  (LOG004)
• invalid-bool-return-type
  (PLE0304)
• too-many-positional-arguments
  (PLR0917)
• stop-iteration-return (PLR1708)
• none-not-at-end-of-union
  (RUF036)
• access-annotations-from-class-dict
  (RUF063)
• duplicate-entry-in-dunder-all
  (RUF068)

The following behaviors have been stabilized:

• blind-except (BLE001) is now suppressed when
  the exception is logged via logging methods other than critical, error and exception.
• future-required-type-annotation
  (FA102) now checks for additional PEP 585-compatible
  APIs, such as those from collections.abc.
• f-string-in-get-text-func-call
  (INT001),
  format-in-get-text-func-call
  (INT002), and
  printf-in-get-text-func-call
  (INT003) now check for additional common ways of using the gettext module, such as assigning
  it to builtins._.
• suspicious-url-open-usage
  (S310) now resolves local string literal bindings to avoid more false positives.
• snmp-insecure-version (S508) and
  snmp-weak-cryptography (S509) now
  support the recommended API from newer versions of PySNMP.
• typing-text-str-alias (UP019) now
  recognizes typing_extensions.Text in addition to typing.Text.
