- A ZCML ``view`` directive (and the associated ``bfg_view``

  decorator) can now accept an "attr" value.  If an "attr" value is
  supplied, it is considered a method named of the view object to be
  called when the response is required.  This is typically only good
  for views that are classes or instances (not so useful for
  functions, as functions typically have no methods other than
  ``__call__``).

- A ZCML ``view`` directive (and the associated ``bfg_view``
  decorator) can now accept a "template" value.  If a "template" value
  is supplied, and the view callable returns a dictionary, the
  associated template is rendered with the dictionary as keyword
  arguments.
