Apple has released updates to the iLife apps for iOS. The company says the updates to iPhoto and iMovie address compatibility issues, while the update to GarageBand addresses minor issues related to general performance and stability. The "compatibility issues" may or may not relate to iOS 7, which is expected to be released to the public in the next several weeks. However, since the updated iLife apps don't feature any new iOS 7-inspired icons, it's likely that Apple will push out further updates to them once iOS 7 ships.
iPhoto, iMovie, and GarageBand for iOS are available in the App Store for US$4.99 each.
