Apple today seeded a revised version of the second iOS 11 beta to developers for testing. The new version has a build number of 15A304j, compared to 15A304i for the original second beta, which was released last Wednesday.



The software update appears to be available for select iPhone and iPad models. It's unclear what revisions have been made at this point.

Registered developers can download the iOS 11 beta from Apple's Developer Center, or over-the-air once the proper configuration profile has been installed. A public beta will be released later this month.

iOS 11 is Apple's biggest software release ever for the iPad, with a new Dock that introduces much improved multitasking, a Files app for better managing files, improved Apple Pencil support, a revamped App Switcher, and system-wide drag and drop.

The update also includes many features for both the iPhone and the iPad, including a redesigned and customizable Control Center, a new Lock screen that's merged with the Notification Center. Peer-to-peer Apple Pay payments are being introduced in the Messages app, which is also gaining a new App Drawer, and there's a new Do Not Disturb feature that is designed to help drivers stay focused on the road. Siri, Photos, the Camera app, and more are also gaining significant improvements.

ARKit for developers will result in a wide range of new augmented reality apps, while a Core ML SDK will allow apps to become a whole lot smarter.
