  +  The updated [NgUpgrade Guide](upgrade.html) guide covers the 
     new AOT friendly `upgrade/static` module 
     released in v.2.2.0, which is the recommended
     facility for migrating from AngularJS to Angular.
  
positive.code:   [StyleGuide](style-guide.html) explains recommended conventions for Angular modules (NgModule).
  
    [StyleGuide](style-guide.html)解释了我们为Angular模块（NgModule）而推荐的约定。
    Barrels now are far less useful and have been removed from the style guide;
    they remain valuable but are not a matter of Angular style.
    Also relaxed the rule that discouraged use of the `@Component.host` property.
  
negative.code: 
    在所有使用`templateUrl`或者`styleUrls`来获取模板或样式的例子组件都被转换为**相对模块**的URL。
    我们添加了`moduleId: module.id`到它们的`@Component`元数据。
    
    This change is a requirement for compilation with AOT compiler when the app loads
    modules with SystemJS as the samples currently do.
