Apple pushed another OS X 10.7.3 build (11D50) to registered developers late last night just one week after their previous seed, making this the 7th build the company has released with no known issues, starting with the first 10.7.3 build on November 15th of last year. Developers have been asked to focus on iCloud Document Storage, Address Book, iCal, Mail, Spotlight, and Safari.
Considering that previous build have been listed with no known issues, and that the last couple of builds have appeared close to a final release, the final update is expected to be released to the public in the very near future.
The main improvements in the update include support for new languages, and fixes for issues with smart cards, authentication for directory services, and Windows file sharing.
