There are two netclass name methods, which previously were not obvious in their uses. These have been renamed to now have: GetName() : Used for internal or tooling (e.g. netlist export) usage GetHumanReadableName() : Used for display to users (e.g. in infobars) Fixing the previous unclear naming will result in fewer bugs when users start using the multiple netclass functionality, as the incorrect usage had started creeping in to new code. Also this will help authors of new code select the correct name method.
