What's New in astroid 4.3.1?

Release date: 2026-08-17

• Fix inference of the attributes of a namedtuple created with
  rename=True. The renamed fields were applied to _fields and to the
  class body, but the instance kept the field names as written, so an instance
  of namedtuple("Tuple", "abc def", rename=True) was inferred as having a
  def attribute instead of _1, and duplicate field names collapsed into
  a single attribute instead of being renamed.

  Closes #242
