  - Tileset properties that require a tileset reload (URL, Source, IonAssetID, IonAccessToken, Materials) have been moved to `private`. Setter and getter methods are now provided for modifying them in Blueprints and C++.
  - Deprecated `CesiumGlobeAnchorParent` and `FloatingPawn`. The `CesiumGlobeAnchorParent` functionality can be recreated using an empty actor with a `CesiumGeoreferenceComponent`. The `FloatingPawn` is now replaced by the `DynamicPawn`. In a future release, the `DynamicPawn` will be renamed to `CesiumFloatingPawn`.
