version 1.3.1. renamed join_polygon_objects() to connect_objects() and added backwards compatibility component. connect_objects() now uses the Connect Objects command by default instead of the Connect + Delete command. It now also performs a check if the specified document is actually in Cinema 4D’s documents list (which is a requirement for the function to work). One can now also specify if it is required to insert the passed objects into the temp doc or even clone them.
