Later today, Apple will release iOS 11, the latest iteration of the software on its iPhones and iPads. Here’s a quick rundown on what’s new, and what to look out for as you update:

New control center. Apple completely redesigned the control center in iOS 11, which is now customizable. You can change to add and remove toggles and links to apps that are more useful for you. For example, you can add buttons to turn on low-power mode, distraction-free driving mode, Apple Wallet, notes, timers, and tons of other features. You can also control your music (and what device you’re listening on) and what networks you’re connected to right from control center.
