- Update to 2.4.1:
* Handle the case where the raw builder fails to retrieve the ``__all__`` attribute
* Restructure the AST parsing heuristic to always pick the same module
* Changed setup.py to work with [distlib](https://pypi.org/project/distlib)
* Do not crash with SyntaxError when parsing namedtuples with invalid label
* Protect against ``infer_call_result`` failing with `InferenceError` in `Super.getattr()`
* Expose a ast_from_string method in AstroidManager, which will accept
* ``BoundMethod.implicit_parameters`` returns a proper value for ``__new__``
* Allow slots added dynamically to a class to still be inferred
* Allow `FunctionDef.getattr` to look into both instance attrs and special attributes
* Infer qualified ``classmethod`` as a classmethod.
* Prevent a recursion error to happen when inferring the declared metaclass of a class
* Raise ``AttributeInferenceError`` when ``getattr()`` receives an empty name
* Prevent a recursion error for self reference variables and `type()` calls.
* Do not infer the first argument of a staticmethod in a metaclass as the class itself
* ``NodeNG.bool_value()`` gained an optional ``context`` parameter
* Pass a context argument to ``astroid.Arguments`` to prevent recursion errors
* Better inference of class and static methods decorated with custom methods
* Reverse the order of decorators for `infer_subscript`
* Prevent a recursion error when inferring self-referential variables without definition
* Numpy `datetime64.astype` return value is inferred as a `ndarray`.
* Skip non ``Assign`` and ``AnnAssign`` nodes from enum reinterpretation
* Numpy ``ndarray`` attributes ``imag`` and ``real`` are now inferred as ``ndarray``.
* Added a call to ``register_transform`` for all functions of the ``brain_numpy_core_multiarray``
* Use the parent of the node when inferring aug assign nodes instead of the statement
* Added some functions to the ``brain_numpy_core_umath`` module
* Added some functions of the ``numpy.core.multiarray`` module
* All the ``numpy ufunc`` functions derived now from a common class that
* ``nodes.Const.itered`` returns a list of ``Const`` nodes, not strings
* The ``shape`` attribute of a ``numpy ndarray`` is now a ``ndarray``
