10.8.1 update still in beta
Apple is already notifying participants in the AppleSeed distribution program that OS X 10.8.2 is in the works, according to 9to5Mac. AppleSeed and Mac Developer builds of releases tend to coincide, which should mean that developers will soon be able to test the update. By extension that may imply that v10.8.1 is almost finished, despite a second beta having just been seeded on Friday.
There's no word on what v10.8.2 might contain, but it could be intended for iOS 6 compatibility, since the latter is due to go live this fall. In the meantime, v10.8.1 appears to be a maintenance release, for instance solving problems with MacBook battery life.
