v4.1.2

Compare Source

============================
Release date: 2026-03-22

• Fix crash accessing property fset in generic classes with type annotations.
  Closes #​2996

• Fix infinite recursion caused by cyclic inference in Constraint.

• Fix RecursionError in _compute_mro() when circular class hierarchies
  are created through runtime name rebinding. Circular bases are now resolved
  to the original class instead of recursing.

  Closes #​2967
  Closes pylint-dev/pylint#10821

• Fix DuplicateBasesError crash in dataclass transform when a class has
  duplicate bases in its MRO (e.g., Protocol appearing both directly and
  indirectly). Catch MroError at .mro() call sites in
  brain_dataclasses.py, consistent with the existing pattern elsewhere.

  Closes #​2628

• Fix FunctionModel returning descriptor attributes for builtin functions.

  Closes #​2743

• Catch MemoryError when inferring f-strings with extremely large format
  widths (e.g. f'{0:11111111111}') so that inference yields Uninferable
  instead of crashing.

  Closes #​2762

• Fix ValueError in __str__/repr and error messages when nodes have
  extreme values (very long identifiers or large integers). Clamp pprint width
  to a minimum of 1 and truncate oversized values in error messages.

  Closes #​2764

v4.1.1

Compare Source

============================
Release date: 2026-02-22

• Let UnboundMethodModel inherit from FunctionModel to improve inference of
  dunder methods for unbound methods.

  Refs #​2741

• Filter Unknown from UnboundMethod and Super special attribute
  lookup to prevent placeholder nodes from leaking during inference.

  Refs #​2741

v4.1.0

Compare Source

============================
Release date: 2026-02-08

• Add support for equality constraints (==, !=) in inference.
  Closes pylint-dev/pylint#3632
  Closes pylint-dev/pylint#3633

• Ensure ast.JoinedStr nodes are Uninferable when the ast.FormattedValue is
  Uninferable. This prevents unexpected-keyword-arg messages in Pylint
  where the Uninferable string appeared in function arguments that were
  constructed dynamically.

  Closes pylint-dev/pylint#10822

• Add support for type constraints (isinstance(x, y)) in inference.

  Closes pylint-dev/pylint#1162
  Closes pylint-dev/pylint#4635
  Closes pylint-dev/pylint#10469

• Make type.__new__() raise clear errors instead of returning None

• Move object dunder methods from FunctionModel to ObjectModel to make them
  available on all object types, not just functions.

  Closes #​2742
  Closes #​2741
  Closes pylint-dev/pylint#6094

• lineno and end_lineno are now available on Arguments.

• Add helper to iterate over all annotations nodes of function arguments,
  Arguments.get_annotations().

  Refs #​2860

• Skip direct parent when determining the Decorator frame.

  Refs pylint-dev/pylint#8425

• Add simple command line interface for astroid to output generated AST.
  Use with python -m astroid.

• Fix incorrect type inference for super().method() calls that return Self.
  Previously, astroid would infer the parent class type instead of the child class type,
  causing pylint E1101 false positives in method chaining scenarios.

  Closes #​457

• Add missing dtype and casting parameters to numpy.concatenate brain.

  Closes #​2870

• Fix ability to detect .py modules inside PATH directories on Windows
  described by a UNC path with a trailing backslash (\)

  • Example: modutils.modpath_from_file(filename=r"\Mac\Code\tests\test_resources.py", path=["\mac\code"]) == ['tests', 'test_resources']

• Fix random.sample inference crash when sequence contains uninferable elements.

  Closes #​2518

• Fix random.sample crash when cloning ClassDef or FunctionDef nodes.

  Closes #​2923

v4.0.4

Compare Source

============================
Release date: 2026-02-07

• Fix is_namespace() crash when search locations contain pathlib.Path objects.

  Closes #​2942

v4.0.3

Compare Source

============================
Release date: 2026-01-03

  results in the face of inference ambiguity.

  Closes #​2899

• Fix base class inference for dataclasses using the PEP 695 typing syntax.

  Refs pylint-dev/pylint#10788
