Apple has released the latest beta version of OS X 10.10.4 to developers and AppleSeed testers.

Developers and AppleSeed testers with the last beta version installed can download the new build now from the Updates section of the Mac App Store. Details on exactly what comes along with OS X 10.10.4 are still vague, with Apple only saying that the update "improves the stability, compatibility, and security of your Mac".

Developers can also grab the latest beta build, 14E26a, from the Mac Developer Center.
