Fine, you got me on "release" vs "release candidate." Still, it is clear that the plan is to release Ember as a 1.0 without Ember.Data (it would be very strange to add something of Ember.Data's scope into a release but not have it in the RC).
I'm aware that Ember.Data is considered separate. The entire point of my post was that I believe this is a mistake.
Ember 1.0 was released? Looks like only an rc-1 so far to me.
Also, Ember-data is a distinct project from Ember itself, no? It's in a different repo (https://github.com/emberjs/data) and states "This is definitely alpha-quality. The basics work, but there are for sure edge cases that are not yet handled."
