Bumps astroid from 4.0.3 to 4.3.0.

Release notes

v4.3.0

What's New in astroid 4.3.0?

Release date: 2026-08-07

Version 4.2.0 was skipped: a v4.2.0 tag was created by mistake during an aborted release attempt, so the changes from the 4.2.0 betas are released as 4.3.0.

• Fix a crash on a functional namedtuple whose field name changes under NFKC normalization, such as namedtuple("mu", ["µ"]). Python normalizes identifiers, so the parsed class stores the field under "μ" while the brain looked it up as written, raising KeyError on a definition that namedtuple itself accepts.

  Closes pylint-dev/pylint#8746

• Fix inference of a method's first argument (self or cls) when the method's return value is stored on an unrelated object. This avoids inferring cls as the caller's class when indexing a tuple returned by a classmethod such as A.c()[0].

  Closes pylint-dev/pylint#11101

• super() with no argument now resolves against the class of the object the method was called on, instead of the class the method is written in. One consequence is that a typing.Self return value survives a chain of super() calls.

  Closes #2852 Closes pylint-dev/pylint#10807

• typing.overload stubs no longer shadow the implementation when a special method is looked up in the MRO.

  Closes #2448

• Fix a crash when the field names of a functional Enum or namedtuple call are bytes, as in Enum("", b""). Such a definition is invalid, so inference now falls back to its default instead of raising TypeError.

  Closes #3189

• Fix a crash when the body of a typing.NamedTuple subclass contains an assignment whose target is not a single name, such as cat.color = "black", basket[0] = "apple" or apple, banana = "red", "yellow". The names bound by unpacking are now copied to the inferred class as well.

  Closes #3190

• Fix a crash when a binary operation involves a class whose metaclass is not a
