- update to 2.9.3:
* Fixed regression where packages without a ``__init__.py`` file were
not recognized or imported correctly.
* Fixed regression in ``astroid.scoped_nodes`` where ``_is_metaclass``
was not accessible anymore.
* ``NodeNG.frame()`` and ``NodeNG.statement()`` will start raising ``ParentMissingError``
instead of ``AttributeError`` in astroid 3.0. This behaviour can already be triggered
by passing ``future=True`` to a ``frame()`` or ``statement()`` call.
* Prefer the module loader get_source() method in AstroidBuilder's
module_build() when possible to avoid assumptions about source
code being available on a filesystem. Otherwise the source cannot
be found and application behavior changes when running within an
embedded hermetic interpreter environment (pyoxidizer, etc.).
* Require Python 3.6.2 to use astroid.
* Removed custom ``distutils`` handling for resolving paths to submodules.
* Fix ``deque.insert()`` signature in ``collections`` brain.
* Fix ``Module`` nodes not having a ``col_offset``, ``end_lineno``, and ``end_col_offset``
attributes.
* Fix typing and update explanation for ``Arguments.args`` being ``None``.
* Fix crash if a variable named ``type`` is subscripted in a generator expression.
* Enable inference of dataclass import from marshmallow_dataclass.
This allows the dataclasses brain to recognize dataclasses annotated by marshmallow_dataclass.
* Resolve symlinks in the import path
Fixes inference error when the import path includes symlinks (e.g. Python
installed on macOS via Homebrew).
