Now the Official Google Blog has its entry on the new version of Google Earth, and more besides. Highlights:

• SketchUp Free for Mac is out! There is a new version for Windows as well — use it to export textured models to Google Earth 4.0.
• Upload KML in Google Maps,, simply by copying and pasting the file’s URL into the Maps text window! This will really speed the adoption of KML. Here is an example using event site Shnitzl‘s KML.
• The Google Maps API now supports geocoding for the US, Canada, Japan, France, Italy, Germany and Spain.
• Google Maps for Enterprise is a fee based service and support option for businesses who want to embed Google Maps in their websites.
