The latest update for Google Maps is now showing up in the Android Market and according to the updated change log it's mostly optimizations of already existing features and battery optimizations -- not that we're complaining. As noted:
- Improved battery performance for Latitude and Location History users, and fresher locations for friends in Latitude
- Transit Navigation (Beta) can use vehicle speed to estimate location if GPS signal is lost
- Increase route options for public transit directions from 3 to 4.
- Report feedback to Google from the settings menu
You'll find the download link past the break and be sure to let us know if you happen to notice any other changes, since Google has a tendency to sneak in some unnoted changes here and there.
