- The ``request_type`` argument to the ``view`` ZCML directive, the
``pyramid.configuration.Configurator.add_view`` method, or the
``pyramid.view.view_config`` decorator (nee ``bfg_view``) is no longer
permitted to be one of the strings ``GET``, ``HEAD``, ``PUT``, ``POST`` or
``DELETE``, and now must always be an interface. Accepting the
method-strings as ``request_type`` was a backwards compatibility strategy
servicing repoze.bfg 1.0 applications. Use the ``request_method``
parameter instead to specify that a view a string request-method predicate.
