Apple has seeded Mac OS X Lion 10.7.2 to Developers only. The build number for this release is 11C26. It is quite surprising that Apple has skipped Lion 10.7.1 and instead launched Lion 10.7.2, most sources are claiming that Lion 10.7.1 release is already imminent and will only consists of bug fixes.
Unlike normal releases, Mac OS X Lion 10.7.2 is not available in Mac developers center, but you can download it via a direct link available on the iCloud beta section. No words on the changes available in this build.
