+
+
+## Breaking Changes
+
+- **VmTurnZone:** due to [a8699da0](https://github.com/angular/angular.dart/commit/a8699da016c754e08502ae24034a86bd8d6e0d8e)
+ 
+
+        `Zone.defaultOnScheduleMicrotask` is now named `Zone.onScheduleMicrotask`
+
+- **compiler:** due to [0e129496](https://github.com/angular/angular.dart/commit/0e1294966d7daacc0aa7866fd9674e8e5695abb5)
+
+        OneWayOneTime bindings will continue to accept value
+        assignments until their stablized value is non-null. The
+        assignment may occur multiple times.  Refer [issue
+        1013](https://github.com/angular/angular.dart/issues/1013).
+
+- **router:** due to [7329d471](https://github.com/angular/angular.dart/commit/7329d4714d04e7167bff2dbc4b5f3c4d1de93d35)
+
+        Previously, vetoing was allowed on leave (RouteLeaveEvent) which caused
+        issues because routes had no way to recover from other route vetoing a leave
+        event.
+
+        Now, similar to preEnter and enter, leave event was split into vetoable
+        preLeave (RoutePreLeaveEvent) and non-vetoable leave (RouteLeaveEvent).
+
+            views.configure({
+              'foo': ngRoute(
+                  path: '/foo',
+                  preLeave: (RoutePreLeaveEvent e) {
+                    e.allowLeave(new Future.value(false));
+                  })
+            });
