Description: This PR contains the following updates: Package Type Update Change Age Confidence PyCQA/pylint repository major v3.3.9 -> v4.0.1 pylint (changelog) dependency-groups major ==3.3.9 -> ==4.0.1 Note: The pre-commit manager in Renovate is not supported by the pre-commit maintainers or community. Please do not report any problems there, instead create a Discussion in the Renovate repository if you have any questions. Release Notes PyCQA/pylint (PyCQA/pylint) v4.0.1 Compare Source What's new in Pylint 4.0.1? Release date: 2025-10-14 False Positives Fixed Exclude __all__ and __future__.annotations from unused-variable. Closes #​10019 Fix false-positive for bare-name-capture-pattern if a case guard is used. Closes #​10647 Check enums created with the Enum() functional syntax to pass against the --class-rgx for the invalid-name check, like other enums. Closes #​10660 v4.0.0 Compare Source Pylint now supports Python 3.14. Pylint's inference engine (astroid) is now much more precise, understanding implicit booleanness and ternary expressions. (Thanks @​zenlyj!) Consider this example: class Result: errors: dict | None = None result = Result() if result.errors: result.errors[field_key] ### inference engine understands result.errors cannot be None ### pylint no longer raises unsubscriptable-object The required astroid version is now 4.0.0. See the astroid changelog for additional fixes, features, and performance improvements applicable to pylint. Handling of invalid-name at the module level was patchy. Now, module-level constants that are reassigned are treated as variables and checked against --variable-rgx rather than --const-rgx. Module-level lists, sets, and objects can pass against either regex. Here, LIMIT is reassigned, so pylint only uses --variable-rgx: LIMIT = 500 # [invalid-name] if sometimes: LIMIT = 1 # [invalid-name] If this is undesired, refactor using exclusive assignment so that it is evident that this assignment happens only once: if sometimes: LIMIT = 1 else: LIMIT = 500 # exclusive assignment: uses const regex, no warning Lists, sets, and objects still pass against either const-rgx or variable-rgx even if reassigned, but are no longer completely skipped: MY_LIST = [] my_list = [] My_List = [] # [invalid-name] Remember to adjust the regexes and allow lists to your liking. Breaking Changes invalid-name now distinguishes module-level constants that are assigned only once from those that are reassigned and now applies --variable-rgx to the latter. Values other than literals (lists, sets, objects) can pass against either the constant or variable regexes (e.g. "LOGGER" or "logger" but not "LoGgEr"). Remember that --good-names or --good-names-rgxs can be provided to explicitly allow good names. Closes #​3585 The unused pylintrc argument to PyLinter.__init__() is deprecated and will be removed. Refs #​6052 Commented out code blocks such as # bar() # TODO: remove dead code will no longer emit fixme. Refs #​9255 pyreverse Run was changed to no longer call sys.exit() in its __init__. You should now call Run(args).run() which will return the exit code instead. Having a class that always raised a SystemExit exception was considered a bug. Normal usage of pyreverse through the CLI will not be affected by this change. Refs #​9689 The suggestion-mode option was removed, as pylint now always emits user-friendly hints instead of false-positive error messages. You should remove it from your conf if it's defined. Refs #​9962 The async.py checker module has been renamed to async_checker.py since async is a Python keyword and cannot be imported directly. This allows for better testing and extensibility of the async checker functionality. Refs #​10071 The message-id of continue-in-finally was changed from E0116 to W0136. The warning is now emitted for every Python version since it will raise a syntax warning in Python 3.14. See PEP 765 - Disallow return/break/continue that exit a finally block. Refs #​10480 Removed support for nmp.NaN alias for numpy.NaN being recognized in ':ref:nan-comparison'. Use np or numpy instead. Refs #​10583 Version requirement for isort has been bumped to >=5.0.0. The internal compatibility for older isort versions exposed via pylint.utils.IsortDriver has been removed. Refs #​10637 New Features comparison-of-constants now uses the unicode from the ast instead of reformatting from the node's values preventing some bad formatting due to utf-8 limitation. The message now uses " instead of ' to better work with what the python ast returns. Refs #​8736 Enhanced pyreverse to properly distinguish between UML relationship types (association, aggregation, composition) based on object ownership semantics. Type annotations without assignment are now treated as associations, parameter assignments as aggregations, and object instantiation as compositions. Closes #​9045 Closes #​9267 The fixme check can now search through docstrings as well as comments, by using check-fixme-in-docstring = true in the [tool.pylint.miscellaneous] section. Closes #​9255 The use-implicit-booleaness-not-x checks now distinguish between comparisons used in boolean contexts and those that are not, enabling them to provide more accurate refactoring suggestions. Closes #​9353 The verbose option now outputs the filenames of the files that have been checked. Previously, it only included the number of checked and skipped files. Closes #​9357 colorized reporter now colorizes messages/categories that have been configured as fail-on in red inverse. This makes it easier to quickly find the errors that are causing pylint CI job failures. Closes #​9898 Enhanced support for @​property decorator in pyreverse to correctly display return types of annotated properties when generating class diagrams. Closes #​10057 Add --max-depth option to pyreverse to control diagram complexity. A depth of 0 shows only top-level packages, 1 shows one level of subpackages, etc. This helps manage visualization of large codebases by limiting the depth of displayed packages and classes. Refs #​10077 Handle deferred evaluation of annotations in Python 3.14. Closes #​10149 Enhanced pyreverse to properly detect aggregations for comprehensions (list, dict, set, generator). Closes #​10236 pyreverse: add support for colorized output when using output format mmd (MermaidJS) and html. Closes #​10242 pypy 3.11 is now officially supported. Refs #​10287 Add support for Python 3.14. Refs #​10467 Add naming styles for ParamSpec and TypeVarTuple that align with the TypeVar style. Refs #​10541 New Checks Add match-statements checker and the following message: bare-name-capture-pattern. This will emit an error message when a name capture pattern is used in a match statement which would make the remaining patterns unreachable. This code is a SyntaxError at runtime. Closes #​7128 Add new check async-context-manager-with-regular-with to detect async context managers used with regular with statements instead of async with. Refs #​10408 Add break-in-finally warning. Using break inside the finally clause will raise a syntax warning in Python 3.14. See PEP 765 - Disallow return/break/continue that exit a finally block _. Refs #​10480 Add new checks for invalid uses of class patterns in :keyword:match. :ref:invalid-match-args-definition is emitted if :py:data:object.__match_args__ isn't a tuple of strings. :ref:too-many-positional-sub-patterns if there are more positional sub-patterns than specified in :py:data:object.__match_args__. :ref:multiple-class-sub-patterns if there are multiple sub-patterns for the same attribute. Refs #​10559 Add additional checks for suboptimal uses of class patterns in :keyword:match. :ref:match-class-bind-self is emitted if a name is bound to self instead of using an as pattern. :ref:match-class-positional-attributes is emitted if a class pattern has positional attributes when keywords could be used. Refs #​10587 Add a consider-math-not-float message. float("nan") and float("inf") are slower than their counterpart math.inf and math.nan by a factor of 4 (notwithstanding the initial import of math) and they are also not well typed when using mypy. This check also catches typos in float calls as a side effect. The :ref:pylint.extensions.code_style need to be activated for this check to work. Refs #​10621 False Positives Fixed Fix a false positive for used-before-assignment when a variable defined under an if and via a named expression (walrus operator) is used later when guarded under the same if test. Closes #​10061 Fix :ref:no-name-in-module for members of concurrent.futures with Python 3.14. Closes #​10632 False Negatives Fixed Fix false negative for used-before-assignment when a TYPE_CHECKING import is used as a type annotation prior to erroneous usage. Refs #​8893 Match cases are now counted as edges in the McCabe graph and will increase the complexity accordingly. Refs #​9667 Check module-level constants with type annotations for invalid-name. Remember to adjust const-naming-style or const-rgx to your liking. Closes #​9770 Fix false negative where function-redefined (E0102) was not reported for functions with a leading underscore. Closes #​9894 We now raise a logging-too-few-args for format string with no interpolation arguments at all (i.e. for something like logging.debug("Awaiting process %s") or logging.debug("Awaiting process {pid}")). Previously we did not raise for such case. Closes #​9999 Fix false negative for used-before-assignment when a function is defined inside a TYPE_CHECKING guard block and used later. Closes #​10028 Fix a false negative for possibly-used-before-assignment when a variable is conditionally defined and later assigned to a type-annotated variable. Closes #​10421 Fix false negative for deprecated-module when a __import__ method is used instead of import sentence. Refs #​10453 Count match cases for too-many-branches check. Refs #​10542 Fix false-negative where :ref:unused-import was not reported for names referenced in a preceding global statement. Refs #​10633 Other Bug Fixes When displaying unicode with surrogates (or other potential UnicodeEncodeError), pylint will now display a '?' character (using encode(encoding="utf-8", errors="replace")) instead of crashing. The functional tests classes are also updated to handle this case. Closes #​8736 Fixed unidiomatic-typecheck only checking left-hand side. Closes #​10217 Fix a crash caused by malformed format strings when using .format with keyword arguments. Closes #​10282 Fix false positive inconsistent-return-statements when using quit() or exit() functions. Closes #​10508 Fix a crash in :ref:nested-min-max when using builtins.min or builtins.max instead of min or max directly. Closes #​10626 Fixed a crash in :ref:unnecessary-dict-index-lookup when the index of an enumerated list was deleted inside a for loop. Closes #​10627 Other Changes Remove support for launching pylint with Python 3.9. Code that supports Python 3.9 can still be linted with the --py-version=3.9 setting. Refs #​10405 Internal Changes Modified test framework to allow for different test output for different Python versions. Refs #​10382 pylint-dev/pylint (pylint) v4.0.1 Compare Source What's new in Pylint 4.0.1?
