   ## 5. Cleanup
-  For RC5, you can leave your components, directives and pipes 
-  in the `directives` and `pipes` properties of your `@Component` metadata.
-  In fact, we automatically hoist (add) them to the NgModule to which they belong.
-
-.alert.is-important
-  :marked
-    This option is temporary for backward compatibility. 
-    It will be removed in the final release of Angular 2.0.
-
-    Get ahead of the game and start moving your component `directives` and `pipes` 
-    into module `declarations` as soon as possible.
-    We intend to delete _all_ deprecated class, methods, and properties in the next RC.
+  Remove all the `directives` and `pipes` properties of your `@Component` metadata. They no
+  longer exist in Angular.
