@Ilwrath:
What I reacted to was the statement that 1.3 and 2.0 offered approximately the same API for applications. Two dimensions I would say. 2.0 is a major overhaul, most stuff is rewritten and much stuff is added. The difference between 2.0 and 3.0 is nothing compared to the difference between 1.3 and 2.0.
Btw, what did you mean with "multiple (and alternative) serial.device handling"?
