All normal. Car sounded fantastic.
N180321 everything changed. Much quieter car.
3 or so weeks later-
N180921 car seems to feel normal again (overruns). But at this point things are getting a bit confusing.
Can't really speak for performance however since I don't really have a good 'butt dyno' baseline that I can vividly recall because car received that second update right after I took car out of winter hibernation. I feel like saying that it does feels a bit different (less lively) but can't with confidence.

Yeah. It's the boost profile that's changed. It's somehow been smoothed out, almost like timing gets pulled slightly early on to round off the peak delivery. I'm really not complaining because I find it more linear now but whatever.
I emailed BMW to ask if they would send me a list of things that changed.
