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 Specifically, :meth:`!find_loader`/:meth:`!find_module` (superseded by :meth:`~importlib.abc.Finder.find_spec`), :meth:`~importlib.abc.Loader.load_module` (superseded by :meth:`~importlib.abc.Loader.exec_module`), :meth:`!module_repr` (which the import system takes care of for you), the ``__package__`` attribute (superseded by ``__spec__.parent``), the ``__loader__`` attribute (superseded by ``__spec__.loader``), and the ``__cached__`` attribute (superseded by ``__spec__.cached``) will slowly be removed (as well as other classes and methods in :mod:`importlib`).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.
