News from Google’s Geo Developer Day, reported by Google Earth Blog, Ogle Earth and The Unofficial Apple Weblog: Google Earth version 4.0 (beta) is now available, with a new interface for all platforms. I say “all platforms,” because there is now a Linux version available for download (see previous entry). The Mac version (see previous entry) is now a Universal binary (it will run natively on Intel- and Power PC-based Macs) and appears to be feature-complete: Plus and Pro versions, for example, are now available on the Mac.
