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.
