Mac OS X 10.10.3 Yosemite has arrived and includes the new Photos app. It’s a free upgrade via the Mac App Store.

Both Aperture, Apple’s US$79.99 pro photo editing software, and iPhoto, geared more toward non-pro end users, are replaced by the Photos, which Apple debuted during the 2014 Worldwide Developer Conference. The new “grounds-up photo solution” will  mirror features of the Photos app in iOS 8. Features of the Photos app, according to Apple, include the ability to:

° Browse photos by time and location in Moments, Collections, and Years views

° Navigate a library using convenient Photos, Shared, Albums, and Projects tabs

° Store all of your photos and videos in iCloud Photo Library in their original format and in full resolution

° Perfect photos with powerful and easy to use editing tools that optimize with a single click or slider, or allow precise adjustments with detailed controls

° Create professional-quality photo books with simplified bookmarking tools, new Apple-designed themes, and new square book formats

° Purchase prints in new square and panoramic sizes.
