Three weeks after Apple released the third developer version of iPadOS 16 for testing, the company seeded the fourth and final version of the operating system for testing.

The iOS and iPadOS 16 profiles can be downloaded from the Apple Developer Center by registered developers.

A new level of personalization and customization is offered by the Lock Screen in the new version of Apple's mobile operating system. Similar to watch faces, multiple lock screens can be associated with focus modes.

Focus is easier to set up than before and has filters to cut out distraction in apps.

If you haven't gotten a response to an email, the Mail app will remind you to check it out. Passkeys, a more secure way to log in to accounts, is being worked on by Apple.

Live Text is supported in video and can be used to share photos with family and friends. There's a new feature that allows you to lift the subject from a background with a tap.

The Home app has been completely overhauled with a new look. The new Stage Manager feature on the iPad is limited to the M1 iPad.

There are a lot of new features in both iPadOS 16 and Apple's mobile operating system.
