+##### Additions :tada:
+
+- Added `CesiumAzureMapsRasterOverlay`.
+
 ##### Fixes :wrench:
 
+- Fixed a bug where `CesiumCreditSystem` would not filter out empty credits, resulting in duplicate on-screen delimiters.
 - Fixed a problem where multi-selecting `UCesiumGlobeAnchorComponent` could cause the selected components to teleport to 0 degrees longitude and 0 degrees latitude. Now, the geospatial position and orientation fields are hidden while multi-selecting.
