Angular 4.0.0 beta6 更新内容：

重大改进：

common：现在需要定义 Iterable 来正确编译 Angular 应用。 在运行时不需要支持 Iterable ，但是类型定义 Iterable 必须可用。

NgFor，现在的 NgForOf在运行时已经支持 Iterable 。通过此更改，类型定义会更新以反映此支持。

Migration：将 “es2015.iterable.ts” 添加到 tsconfig.json“libs” 字段。

Part of #12398：之前 upgrade/static/downgradeInjectable 返回以下形式的数组：

['dep1', 'dep2', ..., function factory(dep1, dep2, ...) { ... }]

现在它返回一个带有 $inject 属性的函数：

factory.$inject = ['dep1', 'dep2', ...];
function factory(dep1, dep2, ...) { ... }
