So I read the various archive posts about that notification and played
with it a little. I can see it being handy, especially for added and
removed objects. The big shortcoming, in my situation anyway, is that
it does not seem to provide me with the keys that changed (in the
NSUpdatedObjectsKey case). Unless I'm missing something?
Thanks,
