Apple has released a new build of OS X Yosemite 10.10.3. The build is available both for developers, as well as for those enrolled in the AppleSeed beta program.

Developers can get this latest build from the Apple Developer Center. AppleSeed testers can grab the update from the Mac App Store Updates section.

OS X 10.10.3 contains the much-anticipated Photos for Mac. Photos for Mac, which will replace both iPhoto and Apple's pro-centered photo app Aperture, lets users view, edit, and sort their photos, and has support for iCloud Photo Library built right in. Additionally, the update contains a number of stability and security improvements.
