The 2017 Prius v

I too am interested in what changes were made from '16 to '17 Prius v.
The article link above did not seem to answer that question.

I think I have found 3 changes:
1) Hands Free Siri telephone/ net option
2) Exterior new color...a blueish green mica
3) Front wheel well liner at fender lip push in retainer clips.

So any new welds, sound deadening, software, other clips etc?
(I was told '15 to '16 had new welding in the front to improve front collision impact safety.)

Is there a technical bulletin (Harley Davidson Motorcycles do this bulletin) or like document show the changes from Toyota?
