+#### Breaking Changes
+
+*     Directives will use the Unbounded visibility by default, whereas before the change they used Self
+
+ ([04baa46e](https://github.com/angular/angular/commit/04baa46e))
+*     This change renames all instances of PipeRegistry to Pipes.
+    As part of this change, the former "defaultPipes" export is
+    now a Pipes instance, instead of a map. The map that was previously
+    called "defaultPipes" no longer exists, but may be accessed via
+    defaultPipes.config.
+
+ ([9a70f84e](https://github.com/angular/angular/commit/9a70f84e))
+
+* We export InjectMetadata instead of InjectAnnotation
+
+  ([b54e7214](https://github.com/angular/angular/commit/b54e7214))
