I do not know anything about an updated board.
I do know that there were some problems with the original board requiring some updates to be done after they came out of production. This involved some jumper wires and some other things that had to be changed. That may or may not be what he is talking about. If it is if you provide APR with your serial number they should be able to tell you if the updates have been made to your unit or not.

I guess a few in the initial release must of needed a board update, but was on the phone for about an hour yesterday with David from APR and helped me out with a new map. I sent him the map I was using and he made some changes and I reloaded the new one.
Truck seems to start quicker now - haven't been on highway yet to see if i get that 55mph buck. Need to set up scangauge to check fuel trims at startup and cruising speed. Gonna go search now and learn about these fuel trims.
