 * Fixed a bug in imagery loading that could cause some or all of the globe to be missing when using an imagery layer that does not cover the entire globe.
 * Fixed a bug that caused `ElipseOutlineGeometry` and `CircleOutlineGeometry` to be extruded to the ground when they should have instead been drawn at height. [#2499](https://github.com/AnalyticalGraphicsInc/cesium/issues/2499).
 * Fixed a bug that prevented per-vertex colors from working with `PolylineGeometry` and `SimplePolylineGeometry` when used asynchronously. [#2516](https://github.com/AnalyticalGraphicsInc/cesium/issues/2516)
+* Fixed a bug that would caused duplicate graphics if non-time-dynamic `Entity` objects were modified in quick succession. [#2514](https://github.com/AnalyticalGraphicsInc/cesium/issues/2514).  
 * Fixed some styling issues with `InfoBox` and `BaseLayerPicker` caused by using Bootstrap with Cesium. [#2487](https://github.com/AnalyticalGraphicsInc/cesium/issues/2479)
 * Added support for rendering a water effect on Quantized-Mesh terrain tiles.
 * Added `pack` and `unpack` functions to `Matrix2` and `Matrix3`.
