Also from Google’s Geo Developer Day. In addition to the new version of Google Earth and upgraded imagery for Google Earth (coming soon to Google Maps), an entry in Google’s official blog announces the following major new features of Google Maps:

1. You can now view Google Earth KML files directly in Google Maps.
2. The API now supports geocoding (for several countries).
3. Google Maps for Enterprise — presumably a solution that does not have the free API’s requirement that a mashup page be publicly accessible.
