Added DiagBox 9.268.

What's New:
Support for the latest SGW (Security Gateway) architecture: On newer platforms (Peugeot 308 III, 408, Opel Astra L), older software versions often crashed with a communication error or displayed an “unknown ECU” message. Version 9.268 correctly identifies new ECU types and the secure gateway architecture. It displays parameters and errors, but immediately warns the user if the SGW is blocking writes.
Database for e-DCS6 hybrids and Euro 6.4 engines: The software now includes parameter tables for the latest mild hybrids (MHEV) with a new automated manual transmission featuring a built-in electric motor (Punch Powertrain’s e-DCS6 transmission) and the latest generation of updated 1.2 PureTech three-cylinder engines.
