The second beta of Mac OS X 10.6.7 has been seeded to developers. This comes just days after the initial build was released last Thursday. This update is a 372MB download, jumping up 35 MB from last week's. The current version of Mac OS X 10.6.6 Snow Leopard was just released earlier this month.
Rumor has it that the build concentrates on developments to the new Mac App Store, AirPort, Bonjour, SMB and Graphics Drivers. According to Apple Insider, additional updates will be unlikely as Apple is focused on the Mac OS X 10.7 Lion scheduled for release this summer.
