+
+
+### BREAKING CHANGES
+
+* **platform-server:** * Bump the dependency on Domino to 2.0 to resolve issues with
+  namespacing
+* **forms:** - `AbstractControl#statusChanges` now emits an event of `'PENDING'` when you call `AbstractControl#markAsPending`
+- Previously it did not emit an event when you called `markAsPending`
+- To migrate you would need to ensure that if you are filtering or checking events from `statusChanges` that you account for the new event when calling `markAsPending`
+* **animations:** When animation is trigged within a disabled zone, the
+associated event (which an instance of AnimationEvent) will no longer
+report the totalTime as 0 (it will emit the actual time of the
+animation). To detect if an animation event is reporting a disabled
+animation then the `event.disabled` property can be used instead.

+
+### BREAKING CHANGES
+
+* **animations:** When animation is triggered within a disabled zone, the
+associated event (which an instance of AnimationEvent) will no longer
+report the totalTime as 0 (it will emit the actual time of the
+animation). To detect if an animation event is reporting a disabled
+animation then the `event.disabled` property can be used instead.
+
+* **forms:** ngModelChange is now emitted after the value/validity is updated on its control.
+
+Previously, ngModelChange was emitted before its underlying control was updated.
+This was fine if you passed through the value directly through the $event keyword, e.g.
+
+```
+<input [(ngModel)]="name" (ngModelChange)="onChange($event)">
+
+onChange(value) {
+   console.log(value);               // would log updated value
+}
+```
+
+However, if you had a handler for the ngModelChange event that checked the value through the control,
+you would get the old value rather than the updated value. e.g:
+
+```
+<input #modelDir="ngModel" [(ngModel)]="name" (ngModelChange)="onChange(modelDir)">
+
+onChange(ngModel: NgModel) {
+  console.log(ngModel.value);        // would log old value, not updated value
+}
+```
+
+Now the value and validity will be updated before the ngModelChange event is emitted,
+so the same setup will log the updated value.
+
+```
+onChange(ngModel: NgModel) {
+   console.log(ngModel.value);       // will log updated value
+}
+```
+
+We think this order will be less confusing when the control is checked directly.
+You will only need to update your app if it has relied on this bug to keep track of the old control value.
+If that is the case, you should be able to track the old value directly by saving it on your component.
