If you want to download the update right away, open your iPhone or iPad’s Settings app, and then navigate to General > Software Update. Fair warning: even though this is a fairly minor release, it’s still possible that you could experience a problem with the update that could require you to restore from a backup. (I speak from personal experience.)
Once you’ve made the update, that should take care of the bug that allowed an attacker access to your full photo library through Control Center on the lock screen. Also, if you are in need of a Greek keyboard, Apple has re-enabled it.
