Apple has announced that it is ceasing development of its Aperture and iPhoto apps. Instead, Apple will be replacing them with its new Photos app (that was announced during its Worldwide Developers Conference).
Jim Dalrymple, at The Loop was given the following statement from Apple:
With the introduction of the new Photos app and iCloud Photo Library, enabling you to safely store all of your photos in iCloud and access them from anywhere, there will be no new development of Aperture. When Photos for OS X ships next year, users will be able to migrate their existing Aperture libraries to Photos for OS X.
The Aperture Blog notes that Apple has said they will provide an update so that Aperture will still work with OS X Yosemite. This will give Aperture users some time to make a decision about where to move their photos to.
