+
+The `GizmoPrimitive3d` trait, which is used to draw primitives using gizmos can now be implemented for custom primitives. 
+If you did not declare any such primitives, you may need to remove this trait as it will now be unused. 
+
+If you did implement `GizmoPrimitive3d` for a custom `GizmoBuffer`-like struct, you will need to move your implementation for custom primitives to the primitive itself and use that implementation in a seperate method on the previously mentioned struct.
