A routeAttributes parameter is added. This takes one or more of the following values:
excludeItinerary: Specifies to not return itinerary items in the response.
routePath: Specifies to return a set of coordinates (latitude/longitude) that define the route. This route attribute gives the same result as setting routePathOutput=Points in the request and is now the recommended way to get route path coordinates (see note below).
A mfa (metadata for alternate routes) is added. When set to 1 (true), detailed route instructions (itinerary items) are not included in the response for alternate routes.
Route sub-leg fields are added to provide summary information for the route leg segments between start and end waypoints and any intermediate via-waypoints
