Apple today seeded build 13D38 of OS X 10.9.3 to developers, just under a week after releasing the fifth OS X beta, build 13D33, and a little over a month after the first 10.9.3 beta.
The beta is available through the Software Update mechanism in the Mac App Store as well as through the Mac Dev Center.
Apple continues to ask developers to focus on Graphics Drivers, Audio, Mail, Contacts and Calendar sync over USB in iTunes, and Safari. As was discovered with the first beta, 10.9.3 adds new support for 4K displays, offering "Retina" resolutions that improve readability along with support for 60Hz output from the Retina MacBook Pro.

Thanks for the correction. Apple knows they have work to do to achieve true graphics parity with Windows.
I don't need nor wait for your answers! I'm checking and remarking what's new in graphics FOR MY HD3000 in OS X latest builds. you can't judge a hardware being old if you don't have an Apple's argumentation in that issue!
Fully supported? I think some of our developer friends on MR have a wish-list for 4.1 features that they don't yet have. And, remember, 4.1 isn't parity with OpenGL on Windows. 4.3 is the latest version available.
