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.

Ember 2.0 is not a traditional major release. After thirteen point releases in
almost two years, we're taking a turn to focus entirely on sweeping out
built-up cruft as a foundation for continued progress.
Ember 2.0 only removes features that were deprecated as of Ember 1.13, so
apps that run on Ember 1.13 without any deprecation warnings should run
without issues on Ember 2.0.
New applications should begin using Ember 2.0 today. Apps requiring Ember-Data
should use Ember-Data 2.0.0-beta.1 (2.0 release coming shortly!).

The PHP development team announces the immediate availability of PHP
5.6.12. 12 security-related issues were fixed in this release.

All PHP 5.6 users are encouraged to upgrade to this version.
