- Removed the ability to pass the following arguments to
  ``pyramid.config.Configurator.add_route``: `view``, ``view_context``.
  ``view_for``, ``view_permission``, ``view_renderer``, and ``view_attr``.
  Using these arguments had been deprecated since Pyramid 1.1.  Instead of
  passing view-related arguments to ``add_route``, use a separate call to
  ``pyramid.config.Configurator.add_view`` to associate a view with a route
  using its ``route_name`` argument.  Note that this impacts the
  ``pyramid.config.Configurator.add_static_view`` function too, because it
  delegates to ``add_route``.
