 * Changed `SceneObject.frame` to read-only result of `Frame.from_transformation(SceneObject.worldtransformation)`, representing the local coordinate system of the scene object in world coordinates.
 * Changed `SceneObject.worldtransformation` to the multiplication of all transformations from the scene object to the root of the scene tree, there will no longer be an additional transformation in relation to the object's frame.
 * Fixed call to `astar_shortest_path` in `Graph.shortest_path`.
+* Fixed `AttributeError` on certain imports in IronPython.
