Apple has updated the iLife suite of apps to better work with the new OS X Yosemite OS which launched last Thursday. Composed of iMovie, iPhoto and Garageband, the iLife apps are getting updated user interface elements and various new features plus Yosemite's iCloud Drive support which enables sharing larger projects among collaborators through the cloud.
This means larger files can be sent over email via iCloud's new Mail Drop feature. These updates are apparently only for Yosemite as the App Store states that Compatibility is stictly OS X 10.10 or later. The Photos app, which Apple demoed previously as a blend of iPhoto and the now discontinued Aperture, will surface in 2015. In the meantime, Aperture users also get a Yosemite update to tide them over until next year.
