The new Google Maps for iOS (free, App Store) just landed and it has native iPad support for the first time. In additional to supporting the iPad's larger screen, the new version of Google Maps includes live traffic and road incident reports. The new version of Maps also offers indoor directions and maps for malls, airports, transit stations, and more.
According to MacRumors Google Maps 2.0 for iOS does not include on-the-fly rerouting (like it does on Android), but Google has said that it plans to add the feature in the future.
Here's the full changelog of the new features in v2.0:
New design for iPad
Enhanced navigation including live traffic updates and incident reports
Explore: A new way to browse and discover popular local places to eat, drink, shop, play and sleep
Simple 5-star ratings and reviews from friends, plus expert Zagat content
Great deals from your favorite brands with Google Offers
Indoor maps with walking directions for malls, transit stations, airports and more
No word yet on whether the new traffic and incident report features are coming from Google's acquisition of Waze in June, but it's unlikley that Google could have integrated that functionality so quickly.
The update is being rolled out gradually over the next 24 hours, so if you don’t see it in the App Store yet, check back soon. I was able to download it immediately on my iPad mini and iPhone 5.
UPDATE: gMaps iOS 2.0 also includes a hidden offline map mode. While the feature hasn't been fully implemented, a blog post by Google Maps Director Daniel Graf reveals how it works. Typing "ok maps" in the search box will save the visible map to your device. A definite nod to the new "ok" syntax in both Google Glass and the upcoming Moto X handset.
Our own Chris Duckett posted screenshots of offline maps in action.
