Apple seeded the second beta of OS X 10.10.3 Yosemite to developers, two and half weeks after releasing the first OS X 10.10.3 beta and nearly four weeks after releasing OS X 10.10.2 to the public



From MacRumors:

The new beta, build 14D87h, is available for registered developers through the Software Update mechanism in the Mac App Store and through the Mac Dev Center. OS X 10.10.3 brings several new features to Yosemite, including the new Photos for OS X app. Photos is designed to serve as a replacement for both iPhoto and Aperture, and is on track to see an early 2015 launch. Early reviews have suggested that while Photos is a suitable replacement for iPhoto, with more advanced tools and performance optimizations, it may leave professional users disappointed, at least in its initial incarnation.
