Apple today seeded the first build of OS X 10.9.4 to developers, approximately two weeks after releasing OS X 10.9.3 to the public. The new beta is available thorugh the Software Update mechanism in the Mac App Store should be listed soon in the Mac Dev Center.
It is unclear what improvements the 10.9.4 update will bring to Mavericks, but it is likely to include bug fixes and stability enhancements. It is also unclear when the beta might be released to the public.
The last Mavericks update, 10.9.3, added enhanced support for 4K displays and restored the ability to sync contacts and calendars between Mac and iOS devices over USB.

Pfft. Forget 10.9.4 beta. 10.10 is coming on Monday :)
You sure the battery isn't dead? :)
I think they may have learnt a lot from iOS 7 and the overhaul won't be anywhere near as drastic.
A flatter UI without sacrificing productivity would be most welcome from me. I don't want change for the sake of it with reduced functionality.

I think its safe to say that Mavericks will reach 10.9.5 before OS X 10.10 is released.
Hey now, iOS 7 isn't a year old for another 4 months. Let's not jump the gun. :p
