Apple Insider reports that Aperture users were notified today that the software would soon be removed from the Mac App Store. Apple instead invited everyone to check out Photos, available now as part of Apple’s OS X 10.10.3 open beta.
Evidently, only customers who initially purchased Aperture from the Store actually received Apple’s note entitled, Aperture News.
As I purchased Aperture on CD I did not receive the notification. However I did receive notification as a registered beta tester.
