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)
• bad-version-info-order (PYI066)
• parenthesize-chained-operators (RUF021)
• unsorted-dunder-all (RUF022)
• 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

The following fixes have been stabilized:

• zip-instead-of-pairwise (RUF007)
