Hamilton C2000 controller question / Changer question?

[cwguy.com]

I just purchase a used Hamilton C2000 controller and was wondering if anyone knew the difference between the firmware versions on them? I looked at Hamilton's website but I believe they do not publish any information like that... or I can not find it?

The one I purchased has a higher firmware version then I run at my car wash.... which kind of made me think about it! I would guess the firmware updates are to interact with Hamilton bill acceptors better? (That's my only guess. : )

Thanks
