Breaking changes
Several rules can now add
from __future__ import annotationsautomaticallyTC001,TC002,TC003,RUF013, andUP037now addfrom __future__ import annotationsas part of their fixes when thelint.future-annotationssetting is enabled. This allows the rules to move more imports intoTYPE_CHECKINGblocks (TC001,TC002, andTC003), use PEP 604 union syntax on Python versions before 3.10 (RUF013), and unquote more annotations (UP037).Full module paths are now used to verify first-party modules
Ruff now checks that the full path to a module exists on disk before categorizing it as a first-party import. This change makes first-party import detection more accurate, helping to avoid false positives on local directories with the same name as a third-party dependency, for example. See the FAQ section on import categorization for more details.
Deprecated rules must now be selected by exact rule code
Ruff will no longer activate deprecated rules selected by their group name or prefix. As noted below, the two remaining deprecated rules were also removed in this release, so this won't affect any current rules, but it will still affect any deprecations in the future.
The deprecated macOS configuration directory fallback has been removed
Ruff will no longer look for a user-level configuration file at
~/Library/Application Support/ruff/ruff.tomlon macOS. This feature was deprecated in v0.5 in favor of using the XDG specification (usually resolving to~/.config/ruff/ruff.toml), like on Linux. The fallback and accompanying deprecation warning have now been removed.Removed Rules
The following rules have been removed:
pandas-df-variable-name(PD901)non-pep604-isinstance(UP038)Stabilization
The following rules have been stabilized and are no longer in preview:
airflow-dag-no-schedule-argument(AIR002)airflow3-removal(AIR301)airflow3-moved-to-provider(AIR302)airflow3-suggested-update(AIR311)airflow3-suggested-to-move-to-provider(AIR312)long-sleep-not-forever(ASYNC116)f-string-number-format(FURB116)os-symlink(PTH211)generic-not-last-base-class(PYI059)redundant-none-literal(PYI061)pytest-raises-ambiguous-pattern(RUF043)unused-unpacked-variable(RUF059)useless-class-metaclass-type(UP050)The following behaviors have been stabilized:
assert-raises-exception(B017) now checks for direct calls tounittest.TestCase.assert_raisesandpytest.raisesinstead of only the context manager forms.missing-trailing-comma(COM812) andprohibited-trailing-comma(COM819) now check for trailing commas in PEP 695 type parameter lists.raw-string-in-exception(EM101) now also checks for byte strings in exception messages.invalid-mock-access(PGH005) now checks forAsyncMockmethods likenot_awaitedin addition to the synchronous variants.useless-import-alias(PLC0414) no longer applies to__init__.pyfiles, where it conflicted with one of the suggested fixes forunused-import(F401).bidirectional-unicode(PLE2502) now also checks for U+061C (Arabic Letter Mark).multiple-with-statements(SIM117) is now marked as always safe.Preview features

This is a follow-up release to 0.12.6. Because of an issue in the package metadata, 0.12.6 failed to publish fully to PyPI and has been yanked. Similarly, there is no GitHub release or Git tag for 0.12.6. The contents of the 0.12.7 release are identical to 0.12.6, except for the updated metadata.

Breaking changes
Detection of more syntax errors
Ruff now detects version-related syntax errors, such as the use of the
matchstatement on Python versions before 3.10, and syntax errors emitted by
CPython's compiler, such as irrefutable
matchpatterns before the finalcasearm.New default Python version handling for syntax errors
Ruff will default to the latest supported Python version (3.13) when
checking for the version-related syntax errors mentioned above to prevent
false positives in projects without a Python version configured. The default
in all other cases, like applying lint rules, is unchanged and remains at the
minimum supported Python version (3.9).
Updated f-string formatting
Ruff now formats multi-line f-strings with format specifiers to avoid adding a
line break after the format specifier. This addresses a change to the Python
grammar in version 3.13.4 that made such a line break a syntax error.
rust-toolchain.tomlis no longer included in source distributionsThe
rust-toolchain.tomlis used to specify a higher Rust version than Ruff'sminimum supported Rust version (MSRV) for development and building release
artifacts. However, when present in source distributions, it would also cause
downstream package maintainers to pull in the same Rust toolchain, even if
their available toolchain was MSRV-compatible.
Removed Rules
The following rules have been removed:
suspicious-xmle-tree-usage(S320)Deprecated Rules
The following rules have been deprecated:

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

collection-literal-concatenation(RUF005) now recognizes slices, inaddition to list literals and variables.
readlines-in-for(FURB129) is now marked as always safe.if-else-block-instead-of-if-exp(SIM108) will now further simplifyexpressions to use
orinstead of anifexpression, where possible.unused-noqa(RUF100) now checks for file-levelnoqacomments as wellas inline comments.
subprocess-without-shell-equals-true(S603) now accepts literal strings,as well as lists and tuples of literal strings, as trusted input.
boolean-type-hint-positional-argument(FBT001) now applies to types thatinclude
bool, likebool | intortyping.Optional[bool], in addition toplain
boolannotations.non-pep604-annotation-union(UP007) has now been split into two rules.UP007now applies only totyping.Union, whilenon-pep604-annotation-optional(UP045) checks for use oftyping.Optional.UP045has also been stabilized in this release, but youmay need to update existing
include,ignore, ornoqasettings toaccommodate this change.
