importlib.metadata
------------------

* Previously, when accessing a distribution metadata directory not
containing a metadata file, ``metadata()`` and ``Distribution.metadata()``
would return an empty ``PackageMetadata`` object as if the file
was present but empty. Now, a ``MetadataNotFound`` exception is raised.
See `importlib_metadata#493 <https://github.com/python/importlib_metadata/issues/493>`_
for background and rationale and and :gh:`143387` for rationale on the
compatibility concerns.
