The second beta of OS X 10.10.5, clocking in at build 14F19a, has been released to developers. It should be available from Apple's Mac Developer Resource Center soon, or through the Updates section of the Mac App Store for those that have the previous beta version installed.

Details are light on the contents of OS X 10.10.5. With OS X El Capitan coming later this year, however, expect a relatively minor release consisting primarily bug fixes and performance improvements.
