 ##### Breaking Changes :mega:
 * Removed `ClippingPlaneCollection.clone` [#6872](https://github.com/AnalyticalGraphicsInc/cesium/pull/6872)
 * Changed `Globe.pick` to return a position in ECEF coordinates regardless of the current scene mode.  This will only effect you if you were working around a bug to make `Globe.pick` work in 2D and Columbus View.  Use `Globe.pickWorldCoordinates` to get the position in world coordinates that correlate to the current scene mode. [#6859](https://github.com/AnalyticalGraphicsInc/cesium/pull/6859)
-* Removed the unused `frameState` parameter in `evaluate` and `evaluateColor` functions [#6890](https://github.com/AnalyticalGraphicsInc/cesium/pull/6890).
+* Removed the unused `frameState` parameter in `evaluate` and `evaluateColor` functions in Expression, StyleExpression, ConditionsExpression and all other places that call the functions. [#6890](https://github.com/AnalyticalGraphicsInc/cesium/pull/6890).
 
 ##### Additions :tada:
 * Added `ClippingPlaneCollection.planeAdded` and `ClippingPlaneCollection.planeRemoved` events.  `planeAdded` is raised when a new plane is added to the collection and `planeRemoved` is raised when a plane is removed. [#6875](https://github.com/AnalyticalGraphicsInc/cesium/pull/6875)
