 * Added `classificationType` property to `PolylineGraphics` and `GroundPolylinePrimitive` which specifies whether a polyline clamped to ground should be clamped to terrain, 3D Tiles, or both. [#7437](https://github.com/AnalyticalGraphicsInc/cesium/pull/7437)
 * Added the ability to specify the width of the intersection volume for `Scene.sampleHeight`, `Scene.clampToHeight`, `Scene.sampleHeightMostDetailed`, and `Scene.clampToHeightMostDetailed`. [#7287](https://github.com/AnalyticalGraphicsInc/cesium/pull/7287)
 * Added a [new Sandcastle example](https://cesiumjs.org/Cesium/Build/Apps/Sandcastle/?src=Time%20Dynamic%20Wheels.html) on using `nodeTransformations` to rotate a model's wheels based on its velocity. [#7361](https://github.com/AnalyticalGraphicsInc/cesium/pull/7361)
+* Added a [new Sandcastle example](https://cesiumjs.org/Cesium/Build/Apps/Sandcastle/?src=Polylines%20on%203D%20Tiles.html) for drawing polylines on 3D Tiles [#7522](https://github.com/AnalyticalGraphicsInc/cesium/pull/7522)
 * Added `EllipsoidRhumbLine` class as a rhumb line counterpart to `EllipsoidGeodesic`. [#7484](https://github.com/AnalyticalGraphicsInc/cesium/pull/7484)
 * Added rhumb line support to `PolygonGeometry`, `PolygonOutlineGeometry`, `PolylineGeometry`, `GroundPolylineGeometry`, and `SimplePolylineGeometry`. [#7492](https://github.com/AnalyticalGraphicsInc/cesium/pull/7492)
 * When using Cesium in Node.js, we now use the combined and minified version for improved performance unless `NODE_ENV` is specifically set to `development`.
