 * 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 `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`.
 * Improved the performance of `QuantizedMeshTerrainData.interpolateHeight`.  [#7508](https://github.com/AnalyticalGraphicsInc/cesium/pull/7508)
