                　　Ember.js 2.7 和 2.8 beta 发布了。Ember.js 2.7是Ember的次要版本，更新了向后兼容；Ember.js 2.8测试版也在今日发布，这个分支将在大约6个星期后发布稳定版，之后将成为下一个LTS版本。
　　Ember是一个雄心勃勃的Web应用程序，消除了样板，并提供了一个标准的应用程序架构的JavaScript框架。
　　Ember.js 2.7 引入了一种新的向后兼容的 API：

• 　　Ember.computed.uniqBy
  

　　更新日志：
　　

• 　　#13764 [BUGFIX] Keep rest positional parameters when nesting contextual components if needed.
  
• 　　#13781 [BUGFIX] Fix NoneLocation#getURL
  
• 　　#13797 [BUGFIX] Ensure didInitAttrs deprecation is stripped in prod.
  
• 　　#13768 [BUGFIX] Update route-recognizer to v0.2.0. This addresses a large number of per-existing bugs related to URL encoding. However, in doing so, it might inevitably break existing workarounds in this area. Please refer to the linked pull request for more details.
  
• 　　#13634 [BUGFIX] Fix issues with rerendering blockless and tagless components.
  
• 　　#13605 [BUGFIX] Ensure pauseTest runs after other async helpers.
  
• 　　#13655 [BUGFIX] Make debugging this._super much easier (remove manual .call / .apply optimizations).
  
• 　　#13672 [BUGFIX] Fix issue with this.render and this.disconnectOutlet in routes.
  
• 　　#13716 [BUGFIX] Ensure that Ember.Test.waiters allows access to configured test waiters.
  
• 　　#13273 [BUGFIX] Fix a number of query param related issues reported.
  
• 　　#13424 [DEPRECATE] Deprecate Ember.Binding. See the deprecation guide for more details.
  
• 　　#13599 [FEATURE] Enable ember-runtime-computed-uniq-by feature.
  

　　Ember.js 2.8 测试版引入了以下新的后向兼容的 API：
ENGINES

• 　　Ember.Engine class - The base class for Ember.Application. Its only public interface is related to initializers and instance initializers, which is then inherited by applications.
  
• 　　Ember.EngineInstance class - The base class for Ember.ApplicationInstance.
  
• 　　mount keyword - Allows for the mounting of routeless engines in templates. This keyword currently only takes one argument, the name of the engine.
  
• mount router DSL - Allows routable engines to be mounted at a location in a route map.
  

　　
　　Enumerable#includes AND Array#includes
　　Ember.String.isHTMLSafe
　　Ember.Test.checkWaiters
　　更新日志：

• 　　#13757 / #13773 [CLEANUP] Remove legacy view layer features.
  
• 　　#13819 [DOC] Add documentation for container (getOwner, etc.)
  
• 　　#13855 [FEATURE ember-string-ishtmlsafe] Enable by defaut.
  
• 　　#13855 [FEATURE ember-application-engines] Enable by default.
