A7.3.1.3	2019/09/30

		Feature Add: Video, Audio, USB, RS232 and IR have each been divided up into individual streams,
			     instead of being integrated into a single stream containing all.  The result may provide
			     better performance in Transmitter switching.

Note: Transmitters and Receivers must all be running the same version of firmware for them to work
with each other.
