Hi Russel,
I upgraded my rev 4 unit right after the PUM was put on the market.  
Plugged it in, downloaded the firmware and started programming without 
any problems. 

I had also made the resistor value change Microchip recommended previous 
to the PUM upgrade also.  Can't recall off the top of my head exactly 
what that was for but I believe it had to do with the programming voltage.
