Is there a good source for firmware history on the GY-HD100 model? I leapfrogged a few versions, and all I can seem to find is the most recent firmware's revision information on the JVC site. I'd like a full history list to see what else the in-between versions fixed - does one exist online somewhere?

JVC seldom releases official info about firmware versions or history.

However, I've been trying to maintain a running tally of firmware versions in this sticky thread.

Yeah, I've noticed that... It's too bad, since I'd like to sort of know what kinds of functions have changed or been added.

Oh well, thanks for trying to keep up with it, Tim.
