 ##### Breaking Changes :mega:
 * `Resource.fetchImage` now returns an `ImageBitmap` instead of `Image` when supported. This allows for decoding images while fetching using `createImageBitmap` to greatly speed up texture upload and decrease frame drops when loading models with large textures. [#7579](https://github.com/AnalyticalGraphicsInc/cesium/pull/7579)
 * `Cesium3DTileStyle.style` now has an empty `Object` as its default value, instead of `undefined`. [#7567](https://github.com/AnalyticalGraphicsInc/cesium/issues/7567)
+* `Scene.clampToHeight` now takes an optional `width` argument before the `result` argument.
 
 ##### Deprecated :hourglass_flowing_sand:
 * `Resource.fetchImage` now takes an options object. Use `resource.fetchImage({ preferBlob: true })` instead of `resource.fetchImage(true)`. The previous function definition will no longer work in 1.57. [#7579](https://github.com/AnalyticalGraphicsInc/cesium/pull/7579)
