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 1.13.0 和 Ember.js 2.0 Beta 发布。Ember.js 1.13.0 至少有 43 名贡献者参与，提交了 680 个 commits。
Ember 1.13 是 1.x 系列的最新版本，也被标记为 1.x 系列的最后一个版本。也是第一个包括 Glimmer 渲染引擎的版本！ 此版本提升了渲染的性能，新的 Ember.js Helper API，同时还包括了一些特性废弃。
Ember.js 1.13 值得关注的废弃特性：
•
All view APIs in Ember. See deprecation guide
■
Ember.CoreView, Ember.View, Ember.CollectionView, Ember.ContainerView
■
{{view 'some-helper'}}
■
The {{view}} keyword for accessing properties on a view
■
Ember.Select and {{view "select"}}. See deprecation guide
■
Ember.LinkView in favor of Ember.LinkComponent. See deprecation guide
•
Options to the {{#each helper that trigger a legacy and poorly performing legacy layer. These options are: itemView, itemViewClass, tagName, emptyView and emptyViewClass.
•
The itemController argument for {{#each.
•
The bind-attr helper. Using helpers and HTMLBars-style attribute binding is preferred.
•
Reading this.get('template') to check for a yielded block on components. Instead, use the hasBlock API.
•
Non-block param {{with
•
The view and viewClass params for {{outlet}}
•
Ember.reduceComputed and Ember.arrayComputed in favor of plain normal array manipulations. See deprecation guide
Ember 2.0 beta 是 2.x 系列的第一个版本，这就表示在 1.x 系列废弃的特性将会在 Ember.js 2.0 移除。Ember 2.0 详细计划请看 The Road to Ember 2.0。Ember.js 2.0 beta 包括 each-in helper；get helper 等等。
Ember 2.0 值得关注的改进：移除一些公共 APIs。
{{render "some-controller"}}
{{each item itemController="some-controller"}} - This usage can be replaced by nesting a component inside the item, and by using helpers.
Ember.ObjectController
Ember.ArrayController
The {{controller}} keyword
needs: on controllers
Ember.CoreView, Ember.View, Ember.ContainerView and Ember.CollectionView
Ember._Metamorph, Ember._MetamorphView
The {{view "some-view"}} helper
The {{view}} keyword
{{each itemView=, {{each itemViewClass=, {{each tagName=, {{each emptyView=, {{each emptyViewClass
Ember.Select and {{view "select"}}
Ember.Checkbox is not removed, but will become a component instead of a view
Ember.Handlebars.helper, Ember.Handlebars.makeBoundHelper and Ember.Handlebars.helper
Ember.Handlebars.compile
Ember 2.0 将会移除的模板 helpers：
{{bindAttr}}
{{bind-attr}} (use HTMLBars-style attribute bindings instead)
{{bind}}
{{template}} (use {{partial}} instead)
{{linkTo}} (use {{link-to}} instead)
{{collection items}}
Non-block params versions of {{#each}} and {{#with}}
Legacy arguments to {{#each}}, {{outlet}}
此外，不再支持 IE8，要求 IE9+。
