Ember 1.8 has been announced. One of the biggest changes is use of metal-views, which improves rendering performance as well as paves the way for more rendering improvements, grouped as "HTMLBars" in the future.
Ember.js 1.6 has been released to the community, following delays caused by the addition of an AMD loader. However, this delay has been largely unremarked upon by the Ember community, with users excited about the new features in version 1.6 and the promise of 1.7.
The Ember.js team has released version 1.5, with new testing features, and an eager URL update that will “provide for a better UX 99% of the time,” according to Ember core team member Robert Jackson. Jackson, posting on the Ember.js blog, described the new version as having “a ton of bug fixes and small improvements” as well as new features in the release.
