 * ``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.
+* Remove dependency on ``pyparsing``, by replacing it with a hand-written parser. This package now has no runtime dependencies (:issue:`468`)
