Today the Ember project is releasing version 3.8 of Ember.js, Ember Data, and Ember CLI. This release kicks off the 3.8 beta cycle for all sub-projects. We encourage our community (especially addon authors) to help test these beta builds and report any bugs before they are published as a final release in six weeks' time. The ember-try addon is a great way to continuously test your projects against the latest Ember releases.
