Apple released iOS 13 a few minutes ago. I have installed it on my iPhone 8 Plus. It does take a while to install. This article lists some of the changes and new features in iOS 13, give it a read. Some of the new items may not apply to you, but it does not hurt to have an overview. The article also mentions iPadOS which will be released on Sept. 24. Now, I am going back to playing around with iOS 13 on my iPhone.
