Apple has released new developer seeds for three upcoming Mac updates. The first is OS X 10.7.2, now in build 11C43. The iCloud Lion client has now been advanced to beta 9, while iPhoto 9.2 is in its third beta. Apple warns that installing the latter will replace any existing installation of iPhoto, and that beta 3 will not open libraries created by beta 1. The only way to revert iPhoto to an earlier version is to do a clean install of OS X and then install iPhoto again separately.
