Apple has just released the golden master version of OS X Lion to Mac developers. We already know that the final, public release of Lion will be coming on July 14th, so it makes sense that Apple would be ready to give the stamp of approval on today's release, as golden master means that , barring any glaring oversight, that this is the final version that customers will be able to purchase in the Mac App Store for $29.99. The build number on the release is 11A511, and Mac devs, you can download it now.
