Apple released the seventh beta of Mac OS 10.7.3 (build 11D50) to developers yesterday amid the hubbub of the financial conference call.
The update lists no known issues and asks developers to focus on iCloud Document Storage, Address Book, iCal, Mail, Spotlight and Safari. The delta update is a 997.01 MB download while the combo is 1.26 GB in size.
The last beta release didn't list known issues, either, so perhaps this update is almost baked and ready. If you're a developer, grab it and poke around.
