Breaking changes

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

• Default to Python 3.9

  Ruff now defaults to Python 3.9 instead of 3.8 if no explicit Python version is configured using ruff.target-version or project.requires-python (#​13896)

• Changed location of pydoclint diagnostics

  pydoclint diagnostics now point to the first-line of the problematic docstring. Previously, this was not the case.

  If you've opted into these preview rules but have them suppressed using
  noqa comments in
  some places, this change may mean that you need to move the noqa suppression
  comments. Most users should be unaffected by this change.

• Use XDG (i.e. ~/.local/bin) instead of the Cargo home directory in the standalone installer

  Previously, Ruff's installer used $CARGO_HOME or ~/.cargo/bin for its target install directory. Now, Ruff will be installed into $XDG_BIN_HOME, $XDG_DATA_HOME/../bin, or ~/.local/bin (in that order).

  This change is only relevant to users of the standalone Ruff installer (using the shell or PowerShell script). If you installed Ruff using uv or pip, you should be unaffected.

• Changes to the line width calculation

  Ruff now uses a new version of the unicode-width Rust crate to calculate the line width. In very rare cases, this may lead to lines containing Unicode characters being reformatted, or being considered too long when they were not before (E501).

Removed Rules

The following deprecated rules have been removed:

• missing-type-self (ANN101)
• missing-type-cls (ANN102)
• syntax-error (E999)
• pytest-missing-fixture-name-underscore (PT004)
• pytest-incorrect-fixture-name-underscore (PT005)
• unpacked-list-comprehension (UP027)

Remapped rules

The following rules have been remapped to new rule codes:

• flake8-type-checking: TCH to TC

Stabilization

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

• builtin-import-shadowing (A004)
• mutable-contextvar-default (B039)
• fast-api-redundant-response-model (FAST001)
• fast-api-non-annotated-dependency (FAST002)
• dict-index-missing-items (PLC0206)
• pep484-style-positional-only-argument (PYI063)
• redundant-final-literal (PYI064)

• parenthesize-chained-operators (RUF021)

• unsorted-dunder-slots (RUF023)
• assert-with-print-message (RUF030)
• unnecessary-default-type-args (UP043)

The following behaviors have been stabilized:

• ambiguous-variable-name (E741): Violations in stub files are now ignored. Stub authors typically don't control variable names.
• printf-string-formatting (UP031): Report all printf-like usages even if no autofix is available

• zip-instead-of-pairwise (RUF007)

v0.7.0

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.

Formatter preview style

• Normalize implicit concatenated f-string quotes per part (#​13539)

Preview linter features

• [refurb] implement hardcoded-string-charset (FURB156) (#​13530)

Rule changes

• [pylint] Mark PLE1141 fix as unsafe (#​13629)
• [flake8-async] Consider async generators to be "checkpoints" for cancel-scope-no-checkpoint (ASYNC100) (#​13639)
• [flake8-bugbear] Do not suggest setting parameter strict= to False in B905 diagnostic message (#​13656)
• [flake8-todos] Only flag the word "TODO", not words starting with "todo" (TD006) (#​13640)
• [pycodestyle] Fix whitespace-related false positives and false negatives inside type-parameter lists (E231, E251) (#​13704)
• [flake8-simplify] Stabilize preview behavior for SIM115 so that the rule can detect files
  being opened from a wider range of standard-library functions (#​12959).
