To visualize easier, here’s a quick refreshment of the difference:
V1 software
Position 1 - Coffee Priority Mode (Stable temp with steam boost)
Position 0 - Steam Priority Mode (Classic HX)
V2 software
Position 1 - Coffee Priority Mode (Stable temp with improved steam boost, meaning it boosts more reliably and consistently)
Position 0 - Coffee Only Mode (Steam boiler is disabled during brewing)
In my experience using Position 1 (Coffee Priority Mode) in V2, the steam boost is much more reliable now and I have never encountered any weak steaming or boiler auto refill during steaming. The cons is that since the steam boost is longer than in V1, it seems to take longer for the group head to stabilize back to the target brew temperature (but I have not tested how long).

@cirus I don’t think it is stated anywhere that V2 software will improve the waiting (cool down/stabilizing) time after pulling a shot.
