What's new in Pylint 4.0.8?

Release date: 2026-08-29

False Positives Fixed

• Fix a false positive for :ref:unspecified-encoding when an open call uses a mode
  argument that cannot be inferred.

  Closes #​10201

• Fix a false positive for invalid-name (C0103) on names assigned in an
  if __name__ == "__main__": block. Such a block reads like a script body, so
  a name there is now accepted if it matches either the constant or the variable
  naming style.

  Closes #​10766

• Fix false positives for :ref:invalid-str-returned, :ref:invalid-repr-returned,
  :ref:invalid-format-returned, :ref:invalid-bytes-returned, :ref:invalid-hash-returned,
  :ref:invalid-index-returned, :ref:invalid-length-returned,
  :ref:invalid-length-hint-returned, :ref:invalid-getnewargs-returned and
  :ref:invalid-getnewargs-ex-returned when the returned value is an instance of a
  subclass of the expected builtin type, such as self in a str subclass or a
  namedtuple.

  Closes #​11306

• Fix false positives for :ref:bad-string-format-type when the argument is an
  instance of a subclass of int, float or str, such as bool or an
  IntEnum member formatted with %d.

  Closes #​11315

False Negatives Fixed

• redundant-unittest-assert now also flags assertEqual and assertNotEqual
  when both compared values are constants, e.g. self.assertEqual(5, 5).

  Closes #​11321

Other Bug Fixes

• Fix a crash in the docparams extension when a raised name does not infer to an exception, such as raise sum or raise some_module. Such objects have no ancestors(), which aborted the whole file with an astroid-error fatal message.

  Closes #​11228

• Fix a crash in the use-yield-from checker (AttributeError: 'Subscript' object has no attribute 'name') when a loop target is a subscript, attribute, or tuple.

  Closes #​11286

• Fix a crash in the docparams extension (AttributeError: 'AssignName' object has no attribute 'decorators') when a class has non-function attributes sharing the name of a property setter.

  Closes #​11287

Other Changes

• Upgrade the isort upper bound so isort 9 can be installed alongside pylint.

  Closes #​11351

v4.0.7

Compare Source

What's new in Pylint 4.0.7?

Release date: 2026-08-09

False Positives Fixed

• Fix a false positive for invalid-name when a module-level variable is assigned
  an instance of a TypedDict subclass. Such a name is a value, not a type
  definition, so it is now checked against the constant or variable regex instead
  of class-rgx.

  Closes #​11231

Other Bug Fixes

• Fix a crash in the bad-open-mode check when the mode argument of
  open is the NotImplemented constant (Python >= 3.14).

  Closes #​11099

• Fix a crash in the not-context-manager and not-async-context-manager
  checks when the context manager infers to a value without a name, such as the
  slice returned by with slice(...) / async with slice(...).

  Closes #​11102

• Fix a false positive for nested-min-max (W3301) when the inner min/max call carries a keyword argument such as key=. Flattening the call dropped the keyword and changed the result, so nested calls whose inner call has keyword arguments are no longer flagged.

  Closes #​11130

• Fix a false suggestion from nested-min-max (W3301): when rewriting a nested min/max into a splat call, arguments positioned after the splatted call were silently dropped, so the suggested code changed the result.

  Closes #​11134

• Fix a false positive for too-many-locals (R0914): PEP 695 type parameters, i.e. the T1 and T2 in a generic def f[T1, T2] signature, were counted as local variables. They are type-system constructs, not runtime locals, and are now excluded from the local-variable count.

  Closes #​11136

• Fix literal-comparison (R0123) emitting a corrupted suggestion for identifiers
  that contain is (e.g. axis is 5 was rendered ax== == 5). The suggestion
  is now rebuilt from the operands and operator.

  Closes #​11146

• Fix false positives in bad-string-format-type (E1307) for valid % formatting:
  %i/%u applied to a float (both truncate like %d) and %a applied to any
  non-int type (%a is type-agnostic like %s/%r).

  Closes #​11147

• Fix a false positive for :ref:useless-parent-delegation when an override changes
  the default value of a positional-only parameter.

  Closes #​11148

• Fixed a crash in comparison-with-callable when comparing a lambda assigned as a class attribute.

  Closes #​11175

• too-many-lines could be reported at the line of a # pylint: disable=too-many-lines
  pragma found in a previously linted module. Pragma positions are now reset between
  modules, so the message is reported at line 1 (or at the current module's own pragma)
  regardless of which files were linted before.

  Refs #​11191

• Fix a crash when a call unpacks a dictionary whose keys are not string
  constants, e.g. copy.copy(**{-1: 1}).

  Closes #​11222
