Ember.js v2.9.0-alpha.2 主要更新内容，完整更新见 #13949。
- #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
willRenderlifecycle 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 usingEmber.set.- “Tagless” components (components with
tagNameset to an empty string) used to ignore anyidattribute, which unintentionally allowed users to repurpose it for their own uses. This is now a hard error (“You cannot useelementIdon a tag-less component”).
