Google is releasing an update to their Maps product for Android phones. With the update comes new features: Voice Search, Transit Directions and Latitude Update.
Voice search is a great addition because typing is tedious on mobile devices. Plus, if you're walking, it's much easier to talk to your phone than to type (and walk into people, poles, etc.).
Meanwhile, if you're using public transportation or walking around an unfamiliar place, transit directions can help you navigate your route. Transit directions are available for over 250 cities.
Latitude has had some glitches fixed and a new experimental feature called Update allows you to update friends and family from your current location.
The update will not be released as an automatic push, so visit Android Market to download the latest version of Google Maps.
