The last update for Google Maps added a new Buzz layer along with Voice Search and other options that sync your favorites. Gilli tipped us off to the fact that Google has gone and updated the app from version 4.0.1 to 4.0.2. My best guess is that the minor version bump fixes bugs found in the upgrade to 4.0 but who knows.
