FirmwarePlugin

I am currently customising Qgroundcontrol Version V4.2.9 and using Ardupilot version Copter-4.4.4 with CubeOrangePlus.

While exploring the QGC source qgroundcontrol/src/FirmwarePlugin/APM/ ,
I understood that, for All versions above Copter-4.1.0, QGC is sending
the FactMetaData file, APMParameterFactMetaData.Copter.4.1.xml (this is also present in the same directory).

Is this a correct approach or we need to send the latest APMParameterFactMetaData file for Copter version 4.4.4?
If we need to send the latest FactMetaData file, how to generate this file.

Please suggest
