Apple has just released a new developer preview of the Mac OS X Lion. It comes after a whole month without any updates on the first release and once again you can get it through the Mac AppStore only.
The new build is 11A419, which means Apple has tested lots of other versions since the original 11A390. It’s also rumored as GM1 (Gold Master 1) and despite it won’t be the final release, it is much more stable and less buggy than the first developer preview.
That being said, it is for developers only. If you are regular user, you can give it a try, but be prepared for bugs and crashes. Also, it won’t update to the final version when it’s out so you’ll have to reinstall your system.
