 ##### Fixes :wrench:
 * The Geocoder widget now takes terrain altitude into account when calculating its final destination.
 * Fixed bug that caused a new `ClippingPlaneCollection` to be created every frame when used with a model entity [#6872](https://github.com/AnalyticalGraphicsInc/cesium/pull/6872)
+* Fixed crash when rendering translucent objects when all shadow maps in the scene set `fromLightSource` to false. [#6883](https://github.com/AnalyticalGraphicsInc/cesium/pull/6883)
