Among all the various software updates released today, also just flipped the switch on a new version of Xcode. Xcode 4.1, after several developer previews, is now available for free on the Mac App Store.

From the changelog:

  • - Includes SDKs for OS X Lion and iOS 4.3
  • - Interface Builder support for Auto Layout and new Aqua controls such as NSPopover
  • - Full screen support in workspace, project, and organizer
  • - Project modernization to identify and resolve out of date build settings
  • - Behaviors can be customized and assigned to unique key bindings
  • - Source control enhancements to pushing, pulling, and management of remote servers
  • - Assistant editor support for display of generated assembly and preprocessed output
  • - Additional bug fixes and stability improvements

Mac OS X Lion is a requirement to download this new version of Xcode. The new 4.1 version, however, shows up as free on older Snow Leopard machines as well.
