-##### Fixes :wrench:
+##### Additions :tada:
+
+- Added support for the `KHR_materials_unlit` glTF extension. This is rendered in Unreal Engine by disabling shadows and making all normals point up (along the ellipsoid surface normal).
 
-- Disable normals for unlit materials, which caused photogrammetry to appear too dark, when "KHR\_materials\_unlit" extension is used.
+In addition to the above, this release updates [cesium-native](https://github.com/CesiumGS/cesium-native) from v0.21.2 to v0.21.3. See the [changelog](https://github.com/CesiumGS/cesium-native/blob/main/CHANGES.md) for a complete list of changes in cesium-native.
