Update to Google Maps improves battery life, public transit options and more

A new version of Google Maps has hit the Android Market today, which simultaneously brings fresher location tracking within Latitude and better battery life -- two welcome improvements that seem contrary to one another. There's also a couple goodies included for the transit-minded folks, as Navigation has been updated to better estimate location when GPS signal is lost, and the number of route options for public transit users has been increased from three to four. Sure, the changes are rather incremental, but who's honestly going to argue with greater battery life? Not us, that's for sure.
