--- a/Doc/whatsnew/3.4.rst +++ b/Doc/whatsnew/3.4.rst @@ -1504,10 +1504,30 @@ Deprecated Python Modules, Functions and :meth:difflib.SequenceMatcher.isbpopular were removed: use x in sm.bjunk and x in sm.bpopular, where sm is a :class:~difflib.SequenceMatcher object. -* :func:importlib.util.module_for_loader is pending deprecation. Using

:func:importlib.util.module_to_load and
:meth:importlib.abc.Loader.init_module_attrs allows subclasses of a loader
to more easily customize module loading. +* As mentioned in :ref:whatsnew-pep-451, a number of :mod:importilb

methods and functions are deprecated: :meth:importlib.find_loader is
replaced by :func:importlib.util.find_spec;
:meth:importlib.machinery.PathFinder.find_module is replaced by
:meth:importlib.machinery.PathFinder.find_spec;
:meth:importlib.abc.MetaPathFinder.find_module is replaced by
:meth:importlib.abc.MetaPathFinder.find_spec;
:meth:importlib.abc.PathEntryFinder.find_loader and
:meth:~importlib.abc.PathEntryFinder.find_module are replaced by
:meth:importlib.abc.PathEntryFinder.find_spec; all of the xxxLoader ABC
load_module methods (:meth:importlib.abc.Loader.load_module,
:meth:importlib.abc.InspectLoader.load_module,
:meth:importlib.abc.FileLoader.load_module,
:meth:importlib.abc.SourceLoader.load_module) should no longer be
implemented, instead loaders should implement an
exec_module method
(:meth:importlib.abc.Loader.exec_module,
:meth:importlib.abc.InspectLoader.exec_module
:meth:importlib.abc.SourceLoader.exec_module) and let the import system
take care of the rest; and
:meth:importlib.abc.Loader.module_repr,
:meth:importlib.util.module_for_loader, :meth:importlib.util.set_loader,
and :meth:importlib.util.set_package are no longer needed because their
functions are now handled automatically by the import system.

The :mod:imp module is pending deprecation. To keep compatibility with Python 2/3 code bases, the module's removal is currently not scheduled.
