Joined by Safari 5.1.1, Lion Recovery Update
Apple is now seeding OS X 10.7.2 to the public. The update is available through Lion's Software Update function, and should measure about 435.5MB in standard form. The main upgrade is support for iCloud, allowing Lion users to sync and backup data such as email, calendars, contacts, and Safari bookmarks and Reading Lists. It is also required for Back to My Mac remote access functions, and Find My Mac device tracking.
Also included with v10.7.2 is Safari 5.1.1, and a raft of smaller but still significant changes. These allow reordering spaces and fullscreen apps in Mission Control, as well dragging files between them. Users can now boot into Lion Recover from a local Time Machine drive, and Apple has made improvements to Active Directory integration, VoiceOver compatibility in Launchpad, and Google contact sync compatibility in Address Book. Some bugfixes target freezing in Keynote, delays in network access after waking from sleep, and lastly a bug that prevented screen zoom from working.
Available at the same time is Lion Recovery Update 1.0. Apple's notes provide scarce detail though, mentioning only "improvements to Lion Recovery" and that it "addresses an issue with Find My Mac when using a firmware password."
