- The ``add_route`` method of a Configurator now accepts a

  ``pregenerator`` argument.  The pregenerator for the resulting route
  is called by ``route_url`` in order to adjust the set of arguments
  passed to it by the user for special purposes, such as Pylons
  'subdomain' support.  It will influence the URL returned by
  ``route_url``.  See the ``repoze.bfg.interfaces.IRoutePregenerator``
  interface for more information.
