Apple has released the third developer beta, and second AppleSeed beta of OS X 10.10.4.

Following a fresh beta release of iOS 8.4, Apple has rolled out the latest beta of OS X 10.10.4 for developers and AppleSeed testers. As usual, notes on the release are vague, with Apple saying that OS X 10.10.4 "improves the stability, compatibility, and security of your Mac". Apart from that, there are no specifics about exactly what is to be found in this release. The build in this version is 14E17e.

This update is available from the Mac Developer Center, or the Updates section of the Mac App Store if they have the latest beta installed. AppleSeed testers can also grab the update from the Mac App Store.
