 ### 1.47 - 2018-07-02
 
+##### Highlights :sparkler:
+* Added support for polylines on terrain [#6689](https://github.com/AnalyticalGraphicsInc/cesium/pull/6689) [#6615](https://github.com/AnalyticalGraphicsInc/cesium/pull/6615)
+* Added `heightReference` and `extrudedHeightReference` properties to `CorridorGraphics`, `EllipseGraphics`, `PolygonGraphics` and `RectangleGraphics`. [#6717](https://github.com/AnalyticalGraphicsInc/cesium/pull/6717)
+* `PostProcessStage` has a `selected` property which is an array of primitives used for selectively applying a post-process stage. [#6476](https://github.com/AnalyticalGraphicsInc/cesium/pull/6476)

 ##### Breaking Changes :mega:
 * glTF 2.0 models corrected to face +Z forwards per specification.  Internally Cesium uses +X as forward, so a new +Z to +X rotation was added for 2.0 models only. To fix models that are oriented incorrectly after this change:
     * If the model faces +X forwards update the glTF to face +Z forwards. This can be done by loading the glTF in a model editor and applying a 90 degree clockwise rotation about the up-axis. Alternatively, add a new root node to the glTF node hierarchy whose `matrix` is `[0,0,1,0,0,1,0,0,-1,0,0,0,0,0,0,1]`.
