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

Breaking changes

• The pytest rules PT001 and PT023 now default to omitting the decorator parentheses when there are no arguments
  (#​12838, #​13292).
  This was a change that we attempted to make in Ruff v0.6.0, but only partially made due to an error on our part.
  See the blog post for more details.
• The useless-try-except rule (in our tryceratops category) has been recoded from TRY302 to
  TRY203 (#​13502). This ensures Ruff's code is consistent with
  the same rule in the tryceratops linter.
• The lint.allow-unused-imports setting has been removed (#​13677). Use
  lint.pyflakes.allow-unused-imports
  instead.

v0.6.1

Compare Source

This is a hotfix release to address an issue with ruff-pre-commit. In v0.6,
Ruff changed its behavior to lint and format Jupyter notebooks by default;
however, due to an oversight, these files were still excluded by default if
Ruff was run via pre-commit, leading to inconsistent behavior.
This has now been fixed.

Breaking changes

See also, the "Remapped rules" section which may result in disabled rules.

• Follow the XDG specification to discover user-level configurations on macOS (same as on other Unix platforms)
• Selecting ALL now excludes deprecated rules
• The released archives now include an extra level of nesting, which can be removed with --strip-components=1 when untarring.
• The release artifact's file name no longer includes the version tag. This enables users to install via /latest URLs on GitHub.

Deprecations

The following rules are now deprecated:

• syntax-error (E999): Syntax errors are now always shown

Remapped rules

The following rules have been remapped to new rule codes:

• blocking-http-call-in-async-function: ASYNC100 to ASYNC210
• open-sleep-or-subprocess-in-async-function: ASYNC101 split into ASYNC220, ASYNC221, ASYNC230, and ASYNC251
• blocking-os-call-in-async-function: ASYNC102 has been merged into ASYNC220 and ASYNC221
• trio-timeout-without-await: TRIO100 to ASYNC100
• trio-sync-call: TRIO105 to ASYNC105
• trio-async-function-with-timeout: TRIO109 to ASYNC109
• trio-unneeded-sleep: TRIO110 to ASYNC110
• trio-zero-sleep-call: TRIO115 to ASYNC115
• repeated-isinstance-calls: PLR1701 to SIM101

Stabilization

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

• mutable-fromkeys-value (RUF024)
• default-factory-kwarg (RUF026)
• django-extra (S610)
• manual-dict-comprehension (PERF403)
• print-empty-string (FURB105)
• readlines-in-for (FURB129)
• if-expr-min-max (FURB136)
• bit-count (FURB161)
