 * `RequestErrorEvent` now includes the headers that were returned with the error response.
 * Added `AssociativeArray`, which is a helper class for maintaining a hash of objects that also needs to be iterated often.
 * Added `TimeIntervalCollection.getChangedEvent` which returns an event that will be raised whenever intervals are updated.
+* Added a second parameter to `Material.fromType` to override default uniforms. [#1522](https://github.com/AnalyticalGraphicsInc/cesium/pull/1522)
 * Added `Intersections2D` class containing operations on 2D triangles.
