Following the release of OS X 10.10.3 earlier this week, which included the new Photos app for OS X, Apple has removed iPhoto and Aperture from the Mac App Store. Both apps are now unavailable for purchase, though they can still be downloaded from the Purchases tab in the store by those who already own the applications.
