As rumored, Nokia has released version 2.5 of its Maps application for Windows Phone. The headline feature is a daily "Groupon Now!" deal integrated into the app. Groupon deals will be shown along with other local search results — they'll be identified with a green "G" and clicking one will direct you to Groupon's mobile site. The Groupon feature will only be available in the US, however. It's the fruits of an exclusive partnership the two companies formed in May.

Nokia has also added a more utilitarian feature: advanced route planning. Along with the standard route creation (via car, walking, or public transit), users will be able to pin saved route to the start screen. Nokia says that the saved routes can also be shared.

The app should be available on Lumia phones now, though the company warns that some regions may have a one or two day delay before it appears in the Windows Phone Marketplace.
