Today, we're announcing our plan for Ember 2.0. While the major version bump gives us the opportunity to simplify the framework in ways that require breaking changes, we are designing Ember 2.0 with migration in mind. This is not a big-bang rewrite; we will continue development on the master branch, and roll out changes incrementally on the 1.x release train. The 2.0.0 release will simply remove features that have been deprecated between now and then. Our goal is that you can move your Ember app to 2.0 incrementally, one sprint at a time.
