As of this morning, downloads of Google Earth are of version 126.96.36.19930 (for Mac and PC) vs 188.8.131.521 Beta previously. I can’t find any changes to the feature set, but perhaps for the Mac version it’ll run more stably on OS X 10.5.1 Leopard. So have a download.
PS: Thanks everyone for sending me links to this article called TechCrunch Heading Towards Extinction? or something:-)
