I wanted to reiterate my love for this new update...much-improved FWD, auto-open and close...I'm just waiting for the time when I'll leave the Model S with the door wide open and just walk away. On a different note, prior to the update, this past weekend, I did have an issue where the drivers side falcon door was just completely stuck. It was "mostly" closed, but the car registered it as open. Despite pushing/pulling and encouraging it to open with multiple override attempts, I powered the car down, popped off the lower speaker panel and pulled the manual release. This is documented in the "first responder" manual and it releases the latch with the door then free to be pushed up. I don't anticipate that I will ever need to do this again, but I thought it would be helpful information to have out there.
As for the loss of the tone on closing, I do think it speeds up the door closing a bit as on the prior software, the tone would register before any movement of the FWD. It would be interesting if you could customize the sound on FWD opening though...(for dramatic effect)
