 #### `ol.interaction.Draw` changes
 
 * The `minPointsPerRing` config option has been renamed to `minPoints`. It is now also available for linestring drawing, not only for polygons.
+* The `ol.DrawEvent` and `ol.DrawEventType` types were renamed to `ol.interaction.DrawEvent` and `ol.interaction.DrawEventType`. This has an impact on your code only if your code is compiled together with ol3.
