 ### 1.46 - 2018-06-01
 
 ##### Breaking Changes :mega:
+* `ParticleSystem` no longer uses `forces`. [#6510](https://github.com/AnalyticalGraphicsInc/cesium/pull/6510)
+* `Particle` no longer uses `size`, `rate`, `lifeTime`, `life`, `minimumLife`, `maximumLife`, `minimumWidth`, `minimumHeight`, `maximumWidth`, and `maximumHeight`. [#6510](https://github.com/AnalyticalGraphicsInc/cesium/pull/6510)
 * Removed `Scene.copyGlobeDepth`. Globe depth will now be copied by default when supported. [#6393](https://github.com/AnalyticalGraphicsInc/cesium/pull/6393)
 * The default `classificationType` for `GroundPrimitive`, `CorridorGraphics`, `EllipseGraphics`, `PolygonGraphics` and `RectangleGraphics` is now `ClassificationType.TERRAIN`.  If you wish the geometry to color both terrain and 3D tiles, pass in the option `classificationType: Cesium.ClassificationType.BOTH`.
