We are pleased to announce that both Ember.js 1.5.0 and the first beta in the 1.6 series
have been released. This comes as the fifth cycle of our six-week release
process that began after 1.0 was released.
New features in 1.5

Handlebars Logging of Primitive Values
This feature allows you to log primitive values (strings, numbers, etc) from within your templates. Previously, the {{log}} helper only allowed usage of bound property lookup.

Although most of our collaboration takes place on Github, IRC
(#emberjs on freenode.net), and our Discourse site
the Ember.js Core Team meets privately every
Friday at 2pm EST/11am PST through Google Hangout for a weekly
discussion of all things Ember.
If you have a topic you'd like to see covered, contact your favorite
core team member and let them know!

TL;DR Ember Data 1.0 is coming soon. We have a few last features to land before we
can confidently make guarantees around not breaking the API. Specifically:

1. A guarantee that if one side of a two-way relationship changes, the other
   side will remain in sync, even if it hasn't loaded yet.
2. All relationships will become async, but DataBoundPromises will make them
   work well in observers, computed properties and in templates.
