+  ## 使用npm的_@types_包替换_typings_ (2016-10-20)

   The "[Angular 1 Upgrade](upgrade.html)" guide reflects this change.

   packages in support of upgrade; these are not needed for pure Angular 2 development.
+  
+  "[从1.x升级](upgrade.html)"指南反映了这个变化。
+  `package.json`安装`@types/angular`和一些`@types/angular-...`包来支持升级。它们在纯Angular 2开发中是不需要的。

+  ## 破坏性变化：`in-memory-web-api` (v.0.1.11) 以esm umd的形式发布 (2016-10-19)

   This change supports ES6 developers and aligns better with typical Angular libraries.
   It does not affect the module's API but it does affect how you load and import it.
   See the <a href="https://github.com/angular/in-memory-web-api/blob/master/CHANGELOG.md#0113-2016-10-20" target="_blank">change note</a>
   in the `in-memory-web-api` repo.

+  
+  ## "路由器"_预加载_语法和_:enter_/_:leave_动画(2016-10-19)

   The router can lazily _preload_ modules _after_ the app starts and
   _before_ the user navigates to them for improved perceived performance.
