Lion update makes minor changes
Apple is now seeding two important software updates to developers. The first is a new build of Mac OS X Lion, identified as 11A444d. Although the file measures approximately 1.22GB, the code is not marked under a "Preview 3" header, implying that it is instead a third build of Preview 2. No details of changes or additions have been listed by Apple.
Also available is a new preview of Xcode 4.1, the upcoming version of Apple's Mac/iOS programming tool. The software is labeled Preview 4, but details have yet to be shared. A final release may coincide with the commercial launch of Lion.
Although Apple isn't supplying any notes with the Lion update, some developers have identified a few minor changes. These include some cosmetic differences, such as cleaner control bars, and new iChat text bubbles. Launchpad has been tweaked to allow a new way of deleting apps (below).
