A couple of weeks following the previous seed, Apple has released OS X 10.9 Mavericks Developer Preview 7 to registered developers. The update is available via Software Update in the Mac App Store. A new Apple Remote Desktop 3.7 seed has also been issued.
– Several new wallpapers included in System Preferences.
– The new release points to a new Mavericks website detailing the new features (not live yet).
A tipster has sent in release notes:
