========== ==========
* Starting in this release, there will be a concerted effort to begin
cleaning up old import semantics that were kept for Python 2.7
compatibility. Specifically,
:meth:`~importlib.abc.PathEntryFinder.find_loader`/:meth:`~importlib.abc.Finder.find_module`
(superseded by :meth:`~importlib.abc.Finder.find_spec`),
:meth:`~importlib.abc.Loader.load_module`
(superseded by :meth:`~importlib.abc.Loader.exec_module`),
:meth:`~importlib.abc.Loader.module_repr` (which the import system
takes care of for you), the ``__package__`` attribute
(superseded by ``__spec__.parent``), the ``__loader__`` attribute
(superseded by ``__spec__.loader``), and the ``__cached__`` attribute
(superseded by ``__spec__.cached``) will slowly be removed (as well
as other classes and methods in :mod:`importlib`).
:exc:`ImportWarning` and/or :exc:`DeprecationWarning` will be raised
as appropriate to help identify code which needs updating during
this transition.
