Apple seeded developers with a new beta version of OS X 10.7.3 yesterday evening, following an initial seeding of the update to a private group of testers earlier this week.
The update carries a build number of 11D36, and as with previous releases, no known issues are listed with the update. Developers are asked to focus on iCloud Document Storage, Address Book, iCal, Mail, Spotlight and Safari for testing.
The delta update for the new build (which can be applied on top of previous builds) comes in at 986MB, whereas the combo version which can be applied to previous versions of Lion comes in at 1.2GB.
