- update to 3.4.0:
#68 and bpo-42090: ``Path.joinpath`` now takes arbitrary
positional arguments and no longer accepts ``add`` as a
keyword argument.
Updated project metadata including badges.
bpo-42043: Add tests capturing subclassing requirements.
#9: ``Path`` objects now expose a ``.filename`` attribute
and rely on that to resolve ``.name`` and ``.parent`` when
the ``Path`` object is at the root of the zipfile.
