The time is coming closer for the final release. Today Apple released another update after a week to MAC OS X Lion 10.7.2 with a new build 11C57. Its previous build was 11C55 which was released a week back.
in their previous build they integrated iCloud to MAC OS X Lion 10.7.2. Before the release of 10.7.2 (11C55) people used to get iCloud betas separately. This build got now known issues as noted my macrumors.
Apple continues to list no known issues with the latest build, and has made no changes to its list of focus areas for testing, which include AddressBook, GraphicsDrivers, iCal, iChat, iCloud, Mac App Store, Mail, MobileMe, Safari, Spotlight, and Time Machine.
