Bumps astroid from 4.0.3 to 4.1.0.

Release notes

Sourced from astroid's releases.

v4.1.0

What's New in astroid 4.1.0?

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

... (truncated)
