Ember v2.3.0-beta.2 发布，此版本主要是 bug 修复： #12626 [BUGFIX] Fix "rest" style positional params in contextual components when using dot syntax. #12627 [CLEANUP] Remove unused ENV flags. Ember.ENV.ENABLE_ALL_FEATURES is removed (wasn't functionally different than Ember.ENV.ENABLE_OPTIONAL_FEATURES). Ember.SHIM_ES5 is removed (Ember 2.x only supports ES5 compliant browsers so this flag was unused). Ember.ENV.DISABLE_RANGE_API is removed (unused since HTMLBars landed in 1.10). #12628 [BUGFIX] Fix processing arguments in rerender for contextual components. #12629 [BUGFIX] Expose ownerInjection method on ContainerProxy. #12636 [BUGFIX] Ensure Ember.Mixin.prototype.toString is defined (prevents issues with Object.seal(Ember.Mixin.prototype) in debug builds. 下载：https://github.com/emberjs/ember.js/archive/v2.3.0-beta.2.zip。 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 v2.3.0-beta.2 发布，Bug 修复版本下载地址
