Earlier today Apple seeded a new build of Mac OS X 10.6.8 to developers. The new build, weighing at the usual 1 GB, is available now for download in the Mac Dev Center and carries number 10K531. As with the previous versions, people familiar with the build tell us focus areas for testing haven't changed -- Apple still wants developers to test AirPort, Graphics Drivers, Mac App Store, Networking, QuickTime and VPN.
The releases of Mac OS X 10.6.8 have been following a weekly schedule, with new builds appearing on Thursdays and Fridays. The last build was released last week -- with the WWDC coming up in less than two weeks and OS X Lion likely to follow shortly after (according to the latest rumors) or throughout the summer, Apple might release 10.6.8 as one last maintenance update to Snow Leopard before the new OS goes public.
