Subject: Behavior Changes ----------------

- The ``repoze.bfg.view.render_view_to_response`` API will no longer
  raise a ValueError if an object returned by a view function it calls
  does not possess certain attributes (``headerlist``, ``app_iter``,
  ``status``).  This API used to attempt to perform a check using the
  ``is_response`` function in ``repoze.bfg.view``, and raised a
  ``ValueError`` if the ``is_response`` check failed.  The
  responsibility is now the caller's to ensure that the return value
  from a view function is a "real" response.

- WSGI environ dicts passed to ``repoze.bfg`` 's Router must now
  contain a REQUEST_METHOD key/value; if they do not, a KeyError will
  be raised (speed).

Implementation Changes
----------------------

- Various speed micro-tweaks.
