According to people familiar with the seed, Apple is asking developers to concentrate on the same areas as the previous 12F20 build, including graphics, PDF viewing, Wi-Fi, and wake from sleep. Like that version, the latest update comes with no known issues.

The first OS X 10.8.5 beta came on June 19, with the seeds coming out regularly every week.

Apple is also releasing beta builds of the forthcoming OS X 10.9 Mavericks, with that cycle seeing delivery every two weeks. The last version, Developer Preview 3, contained some minor changes to how the operating system handles iCloud and the upcoming iCloud Keychain feature.
