iOS 15 is the first major update for iOS to hit the devices.
That update was released last week to fix a bug that caused some users to experience problems with the app, but it has been delayed for a few weeks.
That has caused Apple to update the software with a number of bug fixes and new features that are expected to be rolled out to the devices in the coming weeks.
The last update, iOS 15 beta, is the final update to iOS for iOS devices.
iOS 15 was the first update released in October, and it brought several bug fixes, as well as a new “10.5.4” release to fix an issue with some iCloud syncing.
iOS 11.3, which introduced a feature that allows users to share photos and videos on social media, was released on September 29, 2018.
