Apple has issued an update to OS X Mountain Lion Developer Preview 3. The new build comes as 12A193i and is available through Software Update, which in turn downloads through the Mac App Store, making the update available to all developers with OS X Mountain Lion DP3 currently installed.

Noticeable changes in the new OS X 10.8 build are to Mission Control, Messages, System Preferences, Notifications Center, iCloud integration, and Preview app, but otherwise there do not appear to be significant differences in the Developer Preview 3.1 update. Of course, many bug fixes and resolutions to issues identified in the previous build have also been included, and an update to XCode 4.4 Developer Preview 4 was released alongside the update to build applications for the latest developer release.

OS X Mountain Lion is scheduled to be released to the public in late summer of 2012 and is expected to have more stringent system requirements than OS X Lion.

    You should do clean installs of DP3 and RTM versions. DP3 is via the dev program for free. Mountain Lion RTM will be on App Store for a fee.

    There is heavy iCloud integration in ML, I hope it works well and I also hope a file system of sorts comes to iOS 6 so we can actually access files and content from different apps in iOS like we can in OS X.
