Highlights include:

- Added `Ellipsoid.default` to allow a central place to specify a default ellipsoid value to be used throughout the API where an ellipsoid is not otherwise specified. [#4245](https://github.com/CesiumGS/cesium/issues/4245)
- Various defaults have been updated to adjust when `Ellipsoid.default` is changed to a value other than the WGS84 ellipsoid.
- Fixed diffuse color calculation for PBR materials. Many models will now appear slightly brighter. [#12043](https://github.com/CesiumGS/cesium/pull/12043)
- Fixed the calculation of base color in materials using the KHR_materials_specular extension [#12041](https://github.com/CesiumGS/cesium/issues/12041)
- Adjusted spacing for on screen Credits and updated recommendations for positioning custom ones. [#11912](https://github.com/CesiumGS/cesium/issues/11912)
