Apple has today released a seed of OS X Lion 10.7.2 to developers. It has also released an update to iCloud for Mac, beta software that allows developers to test iCloud integration with Mac and iOS apps. The downloads are available on Apple’s Developer Site.
The new Lion update, which is build number 11c43, is a pre-release version of OS X Lion 10.7.2 provided solely for the purpose of testing iCloud features and is not an official update build. If you’ve installed any previous versions of 10.7.2, you have to revert back to 10.7 using the supplied tool before you update.
The iCloud update is beta 9 and is primarily being used by developers to test the syncing features of iCloud. iPhoto beta 3 is also aimed at those testing Photo Stream and other iCloud features.
iCloud for Lion will integrate with the various features of iCloud.com including Find My iPhone, Mail, Calendars and iWork. iOS 5 is the next major revision to Apple’s software for iPhone, iPod, Apple TV and iPad devices. The new OS is slated for release in the fall of this year. You can see our complete rundown of the iOS announcements at WWDC here.
