- The ``pyramid.events.subscriber`` directive behaved contrary to the

  documentation when passed more than one interface object to its
  constructor.  For example, when the following listener was registered::

     @subscriber(IFoo, IBar)
     def expects_ifoo_events_and_ibar_events(event):
         print event

  The Events chapter docs claimed that the listener would be registered and
  listening for both ``IFoo`` and ``IBar`` events.  Instead, it registered an
  "object event" subscriber which would only be called if an IObjectEvent was
  emitted where the object interface was ``IFoo`` and the event interface was
  ``IBar``.

  The behavior now matches the documentation. If you were relying on the
  buggy behavior of the 1.0 ``subscriber`` directive in order to register an
  object event subscriber, you must now pass a sequence to indicate you'd
  like to register a subscriber for an object event. e.g.:

     @subscriber([IFoo, IBar])
     def expects_object_event(object, event):
         print object, event
