If you're using iOS or iPadOS 14.5 or later, you might see the option to choose between two software update versions. You can update to the latest version of iOS or iPadOS 15 as soon as it's released, or continue to use iOS or iPadOS 14 while still getting important security updates for a period of time.
If you can't see the update on your device, use your computer to update your device manually. Learn how to update your device manually if you're using a Mac with macOS Catalina or later, or if you're using a Mac with macOS Mojave or earlier or a Windows PC.
