新闻 Ember.js v2.9.0-alpha.3 发布，JavaScript 框架 下载

Ember.js v2.9.0-alpha.3 发布了，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。

该版本主要改进：

• 
  #13946: Re-rendering a component manually (i.e. calling this.rerender()) no longer forces everything in its subtree to recompute. Notably, helpers like {{unbound}} are not updated when re-rendering.
  
  
• 
  #13947: The willRender lifecycle hook will be called on a component whenever anything in its subtree has changed.
  
  
• 
  #13948: "Backtracking re-render" is now an error in development mode, and will not work in production builds.
  
  
• 
  {{#each-in}} updates automatically when values are added to the object using Ember.set.
  
  
• 
  "Tagless" components (components with tagName set to an empty string) used to ignore any id attribute, which unintentionally allowed users to repurpose it for their own uses. This is now a hard error ("You cannot use elementId on a tag-less component").
