CHANGES.md

@@ -6,6 +6,9 @@ Change Log
 ##### Breaking Changes :mega:
 * `TerrainProviders` that implement `availability` must now also implement the `loadTileDataAvailability` method.
 
+##### Deprecated :hourglass_flowing_sand:
+* The property `ModelAnimation.speedup` has been deprecated and renamed to `ModelAnimation.multiplier`. `speedup` will be removed in version 1.54. [#7393](https://github.com/AnalyticalGraphicsInc/cesium/pull/7393)
+
 ##### Additions :tada:
 * Added functions to get the most detailed height of 3D Tiles on-screen or off-screen. [#7115](https://github.com/AnalyticalGraphicsInc/cesium/pull/7115)
     * Added `Scene.sampleHeightMostDetailed`, an asynchronous version of `Scene.sampleHeight` that uses the maximum level of detail for 3D Tiles.
