Software has struggled in competition with Lightroom
Development of Aperture has halted, and is instead shifting to the editing tools in OS X Yosemite's Photos app, Apple has announced. Photos -- which will actually miss the launch of Yosemite, and ship in early 2015 -- will include an option to import Aperture libraries. Compatibility updates should let Aperture run in Yosemite, but no further support is planned. Apple and Adobe are cooperating to help some users migrate to Lightroom.
Aperture is Apple's current entry into professional photo workflow software, but it has struggled to compete with Lightroom. The last major upgrade of Aperture in fact came in 2010, whereas Adobe has been updating Lightroom almost continually.
Even iPhoto, aimed at casual users, has been relatively neglected, and will be likewise replaced by Photos. Its last significant update was released in 2011. The software gained 64-bit support, and sorting by location or facial recognition.
