The Lion just purred.
Apple pushed out an update to the developer preview of the next Mac operating system today. Mac OS X 10.7 Lion Developer Preview Update 1 is available via Software Update and is the first update since the developer preview first came out on February 24, 2011.
The update is minuscule -- 2.2 MB -- and according to the update notes "This update is required to redeem downloads of Mac OS X Lion seed builds from the Mac App Store." There you have it -- future updates of the seed builds will be done through the Mac App Store and not Software Update.
The update follows recent reports that Apple was set to deploy a Golden Master release of the operating system, which means that the feature set for Lion could be close to being cast in stone.
