Apple will skip iPadOS 16.0 and move full speed ahead with iPadOS 16.1. Look for the operating system update in October, along with new iPads.
In a comment to TechCrunch, Apple had this to say: “This is an especially big year for iPadOS. As its own platform with features specifically designed for iPad, we have the flexibility to deliver iPadOS on its own schedule. This Fall, iPadOS will ship after iOS, as version 16.1 in a free software update.”
This means the first version of iPadOS 16 will ship to non-beta users after the arrival of the first iOS version.
