there have been a couple of different versions.

the 2.0 refers to an entirely different system. the power supplies, wiring, and boards are different from the originals. the original system was set up like an old Christmas tree. the data went from one board, to the next, to the next. while there were some issues with the first run of the boards, the later versions were much more stable. mine has been flawless since i unboxed it new in November of 2013.

the 2.0 system was developed in part because the current led driver that was being used was scheduled for EOL (end of life) by the company that made it. A new driver would have to be acquired and a system designed around that. they (JJP) could have just redone the original system with the new driver, but decided to redo the entire system to fall in line with the way it should have been from the start. The 2.0 system in Woz is the same style system used in Hobbit, Dialed in and now Pirates too.
