"Apple has seeded the golden master version of OS X Lion to developers ahead of its public release sometime this month (July). The golden master download is available from Apple's Mac Developer website. The build number is 11A511. In addition, Apple has seeded Developer Preview 7 of Xcode 4.1." You'll now also be allowed to virtualise several instances of Mac OS X inside Mac OS X.
