-Intersection (new feature, also ability to Speak in Intersection)
-City (ability to Speak in City)
-Business (ability to Speak in Search)
-Airports (ability to Speak in Airport)
-Contact (from your address book)

The Search menu:
(not much changed, now can Speak in Search from menu)

Maps and Traffic:
-takes you to a map of your current location
-Options from menu (Hide Traffic, Commute Alert, Share Location, Curson Address, Get New Map)
-Zoom buttons changed to Q(+) and P(-)

Share & More menu:
- Share Address (uses SMS i presume)
