I found one definitive notable change in 17.34. The folding mirror routines have changed. The mirrors used to be able to be folded at any time with no restriction, and stay folded. This has changed. Now you can only fold them when below 10MPH, and if they are already folded when you start moving, they automatically unfold at 10MPH. Also, the mirrors used to unfold when you opened the door. Now they unfold when you unlock the car. Note that, since receiving my car, it always stated in the manual that the mirrors would automatically unfold upon reaching 25MPH, and that you could not fold them at speeds in excess of 25MPH (even though that was never the case). The owner's manual in the car has now been modified to state 10MPH and that they unfold when unlocking. Personally, I don't care so much about the change in automatic unfolding at speed, the lockout of folding at speed, or the speed at which this happens. What I do not like though, is that the mirrors are now unfolding and folding every time I walk by my car, or I go to retrieve something from my car, or worse yet: I fold them to summon into a tight spot, and then when I get back they unfold as the car unlocks.
