I think this looses something in translation.
However, if you are asking about the latest firmware for the multiplus, very old models need VE Flash to update.

this is an old machine with small microprocessor.

I don’t think that Victron are committed to updating these older machines with small processors. The probably don’t have the capacity needed to install all of the newer features.
