both the modification time and size of the source file the bytecode file was
compiled from.
* :func:`pkgutil.iter_modules` and :func:`pkgutil.walk_packages` no longer work
with modules imported using the default import system. Both functions have
always relied on a non-standard method (``iter_modules()``) to be defined on
loaders to work and the import system now always provides a loader for
modules but does not implement the non-standard method.
* :mod:`pkgutil` has been converted to use :mod:`importlib` internally. This
eliminates many edge cases where the old behaviour of the PEP 302 import
emulation failed to match the behaviour of the real import system. The
import emulation itself is still present, but is now deprecated. The
:func:`pkgutil.iter_importers` and :func:`pkgutil.walk_packages` functions
special case the standard import hooks so they are still supported even
though they do not provide the non-standard ``iter_modules()`` method.
