I've been eagerly awaiting these gee-wiz-bang space-age changes, but when I looked over the change list for 3.4.0 that Ethan sent they seem like mostly minor changes. Or perhaps they just don't describe things in enough detail to match up the rather significant architectural changes listed above. Is this the super-summarized bullet item that refers to the change above?
