+---------------------------

+- The key/values in the ``_query`` parameter of ``request.route_url`` and the
+  ``query`` parameter of ``request.resource_url`` (and their variants), used
+  to encode a value of ``None`` as the string ``'None'``, leaving the resulting
+  query string to be ``a=b&key=None``. The value is now dropped in this
+  situation, leaving a query string of ``a=b&key``.
