More modern look coming this fall.
Apple Seeds OS X 10.7.3 Build 11D24 to Developers
For the new build, Apple has added Spotlight and Safari to the list of areas upon which developers are asked to focus their attention. Developers are asked to continue looking at iCloud Document Storage, Address Book, iCal, and Mail as had been documented in the earlier seed. No known issues with the current build have been documented by Apple.
A targeted public release timeframe for OS X 10.7.3 is currently unknown. The release will come as a follow-up to OS X 10.7.2, which appeared in mid-October to support iCloud.
