  • OS4X Enterprise:
    • New: Added compatibility with Volvo Truck ENGDAT packages. Additionally, files without filenames in the ENGDAT are named according to their compression characteristics.
    • New: Server-side file selection now also supports the username as a variable in the directory name.
    • Improved: The „ENGDATv2 encode“ plugin has been modified to include numerous options for modifying the UNB segment.
