My 2014 P85 VIN 42,XXX flagged this as available during the day Tuesday and I had noticed supercharging speed drastically cut a couple weeks ago I don't supercharger much so unsure which update did it.
This was like the third update in a month and a factor in getting it might have been a service appointment not related to charging scheduled for tomorrow. Wonder if they roll out updates to cars ahead of service, have no evidence of this but could save techs time vs the waiting for it to install once there.
