Ember.js 2.1 beta is released today. As a minor release, Ember 2.1 will be
backwards compatible with Ember 2.0. Any changes to the API will be additive.
This continues Ember's commitment to Semantic Versioning
we began with the 1.0 release.
In addition it means many of the first features for Ember 2.2, most notably angle
bracket components, have landed in Canary behind a feature flag. If you're
interested in help us progress with those features, now is a good time to
try them out.
