Feature Flags

• ember-libraries-isregistered

  Add isRegistered to Ember.libraries. This convenience method checks whether a library is registered with Ember or not.

• ember-routing-routable-components

  Implements RFC emberjs/rfcs#38, adding support for routable components.

• ember-route-serializers

  Deprecates Route#serialize and introduces a serialize option to the router DSL as a replacement (as per the Route Serializers RFC).

• ember-runtime-computed-uniq-by

  Introduces a computed and enumerable method "uniqBy" that allows creation of a new enumerable with unique values as determined by the given property key.

  Example:

  comments: [
    {id: 1, comment: 'I\'m a duplicate comment!'},
    {id: 2, comment: 'Then you should be fixed!'},
    {id: 1, comment: 'I\'m a duplicate comment!'}
  ],
  dedupedComments: Ember.computed.uniqBy('comments', 'id')
  

• ember-improved-instrumentation

  Adds additional instrumentation to Ember:

  • interaction.<event-name> for events handled by a component.
  • interaction.ember-action for closure actions.
  • interaction.link-to for link-to execution.

• ember-runtime-enumerable-includes

Deprecates Enumerable#contains and Array#contains in favor of Enumerable#includes and Array#includes to stay in line with ES standards (see RFC).

• ember-string-ishtmlsafe

  Introduces an API to detect if strings are decorated as htmlSafe. Example:

  var plainString = 'plain string',
      safeString = Ember.String.htmlSafe('<div>someValue</div>');
  
  Ember.String.isHtmlSafe(plainString); // false
  Ember.String.isHtmlSafe(safeString);  // true

• ember-testing-check-waiters

Expose a simple mechanism for test tooling to determine if all foreign async has been handled before continueing the test. Replaces the intimate API Ember.Test.waiters (with a deprecation).
