+
+
+### BREAKING CHANGES
+
+* **forms:** The `emitEvent` option was added to the following `FormArray` and `FormGroup` methods:
+
+* FormGroup.addControl
+* FormGroup.removeControl
+* FormGroup.setControl
+* FormArray.push
+* FormArray.insert
+* FormArray.removeAt
+* FormArray.setControl
+* FormArray.clear
+
+If your app has custom classes that extend `FormArray` or `FormGroup` classes and override the
+above-mentioned methods, you may need to update your implementation to take the new options into
+account and make sure that overrides are compatible from a types perspective.
