A few minutes ago, Apple released Mac OS X Lion 10.7.2 beta build 11C43, iCloud beta 9 and iPhoto 9.2 beta 3 for Mac OS X application developers. The new version of the operating system and applications bring the solution of some of the existing problems and that's about it from a software point of view. The main reason for the release of new versions is of course iCloud, for which Apple asks to receive feedback from application developers. You can download the new updates from the portal dedicated to developers on the Apple website.
