 *unreleased*
 ~~~~~~~~~~~~
 
+* Added ``packaging.utils.create_wheel_filename()`` and ``create_sdist_filename()`` (:issue:`408`)
 * ``Marker.evaluate`` will now assume evaluation environment with empty ``extra``.
   Evaluating markers like ``"extra == 'xyz'"`` without passing any extra in the
   ``environment`` will no longer raise an exception.

+    The project name is normalized such that the non-alphanumeric

+    :class:`~packaging.version.Version`. The build tag can be None,
+    an empty tuple or a two-item tuple of an integer and a string.
+    The tags is set of tags that will be compressed into a wheel
+    tag string.
