Apple today seeded build 12D50 of OS X 10.8.3 Mountain Lion to developers, the fifth beta release reports 9to5Mac. The first 10.8.3 beta was seeded back in November, and the third and fourth releases were released in December.
Though the update comes with no known issues or new features, as before Apple has asked developers to focus on AirPlay, AirPort, Game Center, Graphics Drivers, and Safari in their testing. Registered developers can download it via the Apple Developer Page.

1. Apple's laziness to launch an OS with so many glitches in their OWN unique hardware.
2. Stop adding BS social features and focus on quality.
3. If Apple wants to add new features, then start copying Windows 8 GREAT file copying and management. That is what desktop OSes do, anyway. This is not an iPad.
Well see now. Macs aren't used to being shut down or rebooted. That's a Windows thing.
:D
I don't get why you re wrote this cause its already there in the article above
EDIT Read post #85, as some have called my information into question I have added links and facts to support that Craig Federighi was head of OS X development two years prior to Serlet's March 2011 announcement for departure. Craig Federighi has been head of OS X development since his return to Apple in 2009.
Issues related with Graphic drivers: Choppy Animations, Memory Leaks when apps use GPU/hardware acceleration, Kernal Panics.
Other problems: CRAZY Shutdown times, poor battery life.
Here's what should be added: GPU accelerated scrolling in Mail, Preview (similar to Safari), option to do a three dinger swipe in all apps when it's enabled in Trackpad settings.
Edit: I have a MBP 13" mid 2010. But I've also seen most of these problems on RetinaMBPs
