- A new method of the ``Configurator`` exists:

  ``set_request_factory``.  If used, this method will set the factory
  used by the :mod:`repoze.bfg` router to create all request objects.

- The ``Configurator`` constructor takes an additional argument:
  ``request_factory``.  If used, this argument will set the factory
  used by the :mod:`repoze.bfg` router to create all request objects.

- The ``Hooks`` narrative chapter now contains a section about
  changing the request factory.
