0.11.0
Release Notes
This is a follow-up to release 0.10.0. The requires-python inference changes were unintentionally omitted from 0.10.0, and have been included here. This release also includes stabilization of the preview behavior for PGH004.
Breaking changes
-
Changes to how the Python version is inferred when a
target-versionis not specified (#16319)In previous versions of Ruff, you could specify your Python version with:
- The
target-versionoption in aruff.tomlfile or the[tool.ruff]section of a pyproject.toml file. - The
project.requires-pythonfield in apyproject.tomlfile with a[tool.ruff]section.
These options worked well in most cases, and are still recommended for fine control of the Python version. However, because of the way Ruff discovers config files,
pyproject.tomlfiles without a[tool.ruff]section would be ignored, including therequires-pythonsetting. Ruff would then use the default Python version (3.9 as of this writing) instead, which is surprising when you've attempted to request another version.In v0.10, config discovery has been updated to address this issue:
- If Ruff finds a
ruff.tomlfile without atarget-version, it will check
for apyproject.tomlfile in the same directory and respect its
requires-pythonversion, even if it does not contain a[tool.ruff]
section. - If Ruff finds a user-level configuration, the
requires-pythonfield of the closestpyproject.tomlin a parent directory will take precedence. - If there is no config file (
ruff.tomlorpyproject.tomlwith a
[tool.ruff]section) in the directory of the file being checked, Ruff will
search for the closestpyproject.tomlin the parent directories and use its
requires-pythonsetting.
- The
Stabilization
The following behaviors have been stabilized:
blanket-noqa(PGH004): Also detect blanked file-level noqa comments (and not just line level comments).
Preview features
- [syntax-errors] Tuple unpacking in
forstatement iterator clause before Python 3.9 (#16558)

Changes to how the Python version is inferred when a
target-versionis not specified (#16319)While this change was intended to be released in 0.10.0, it was unintentionally omitted. It was subsequently released in 0.11.0 — see the changelog there for details.
-
Updated
TYPE_CHECKINGbehavior (#16669)Previously, Ruff only recognized typechecking blocks that tested the
typing.TYPE_CHECKINGsymbol. Now, Ruff recognizes any local variable namedTYPE_CHECKING. This release also removes support for the legacyif 0:andif False:typechecking checks. Use a localTYPE_CHECKINGvariable instead. -
More robust noqa parsing (#16483)
The syntax for both file-level and in-line suppression comments has been unified and made more robust to certain errors. In most cases, this will result in more suppression comments being read by Ruff, but there are a few instances where previously read comments will now log an error to the user instead. Please refer to the documentation on Error suppression for the full specification.
-
Avoid unnecessary parentheses around with statements with a single context manager and a trailing comment (#14005)
This change fixes a bug in the formatter where it introduced unnecessary parentheses around with statements with a single context manager and a trailing comment. This change may result in a change in formatting for some users.
-
Bump alpine default tag to 3.21 for derived Docker images (#16456)
Alpine 3.21 was released in Dec 2024 and is used in the official Alpine-based Python images. Now the ruff:alpine image will use 3.21 instead of 3.20 and ruff:alpine3.20 will no longer be updated.
Deprecated Rules
The following rules have been deprecated:
non-pep604-isinstance(UP038)suspicious-xmle-tree-usage(S320)
Remapped rules
The following rules have been remapped to new rule codes:
- [
unsafe-markup-use]:RUF035toS704
Stabilization
The following rules have been stabilized and are no longer in preview:
batched-without-explicit-strict(B911)unnecessary-dict-comprehension-for-iterable(C420)datetime-min-max(DTZ901)fast-api-unused-path-parameter(FAST003)root-logger-call(LOG015)len-test(PLC1802)shallow-copy-environ(PLW1507)os-listdir(PTH208)invalid-pathlib-with-suffix(PTH210)invalid-assert-message-literal-argument(RUF040)unnecessary-nested-literal(RUF041)unnecessary-cast-to-int(RUF046)map-int-version-parsing(RUF048)if-key-in-dict-del(RUF051)unsafe-markup-use(S704). This rule has also been renamed fromRUF035.split-static-string(SIM905)runtime-cast-value(TC006)unquoted-type-alias(TC007)non-pep646-unpack(UP044)
The following behaviors have been stabilized:
bad-staticmethod-argument(PLW0211)invalid-first-argument-name-for-class-method(N804):__new__methods are now no longer flagged byinvalid-first-argument-name-for-class-method(N804) but instead bybad-staticmethod-argument(PLW0211)bad-str-strip-call(PLE1310): The rule now applies to objects which are known to have typestrorbytes.custom-type-var-for-self(PYI019): More accurate detection of customTypeVarsreplaceable bySelf. The range of the diagnostic is now the full function header rather than just the return annotation.invalid-argument-name(N803): Ignore argument names of functions decorated withtyping.overrideinvalid-envvar-default(PLW1508): Detect default value arguments toos.environ.getwith invalid type.pytest-raises-with-multiple-statements(PT012)pytest-warns-with-multiple-statements(PT031): Allowforstatements with an empty body inpytest.raisesandpytest.warnswithstatements.redundant-open-modes(UP015): The diagnostic range is now the range of the redundant mode argument where it previously was the range of the entire open call. You may have to replace yournoqacomments when suppressingUP015.stdlib-module-shadowing(A005): Changes the default value oflint.flake8-builtins.strict-checkingfromtruetofalse.type-none-comparison(FURB169): Now also recognizestype(expr) is type(None)comparisons whereexprisn't a name expression.
The following fixes or improvements to fixes have been stabilized:
