    • cutRoutes.py can now handle nested stops in a vehicle definition.
    • added routeStats.py for computing statistics on route length.
    • added traceExporter.py option --orig-ids <BOOL> for keeping the original vehicle IDs instead of a running index. For some output formats such as NS2 this only works if the vehicle IDs are numeric to begin with.
    • route2trips.py now preserves vType elements.
