iOS 10 has introduced a new 3D Touch feature that allows you to prioritize your app updates. It probably isn't something you'll use terribly often but may come in handy if you have a ton of apps to update and you want to use one of them quickly. To use the feature, tap the "Update all" in your updates section of the App Store, then head back out and go to the app you want to prioritize. Deep press on it and you will have options to prioritize the download (putting it ahead of all the other updating apps), pause or cancel it.
How do I prioritize app updates?
