The fourth beta round of iOS 16, iPadOS 16, tvOS 16, and watchOS 9 are now available to the public.
The fourth public beta versions of the new software should be identical to the sixth developer counterparts, which were released on Monday.
Apple released the third public beta on August 9.
New features in iOS 16 include a redesigned Lock Screen with support for widgets and additional customization, the ability to edit or delete iMessages, and an Apple Pay Later installment plan, among a slew of other features.
New to iPadOS 16 is Stage Manager, which allows users to take advantage of windowed multitasking.
As usual, tvOS 16 will receive smaller updates primarily geared toward stability and performance improvements. Some more significant updates include additional gaming controller support, new Smart Home features, and cross-device compatibility.
Updates to watchOS 9 include new workout views and a medications tracking app. A few new watch faces are also available along with updates to older faces to support new complications.
Those interested in trying out the latest features can sign up for Apple's Beta Software Program and download the new betas from the associated web portal.
The iOS 16 and iPadOS 16 public betas have a build number of 20A5349b, replacing the previous build, 20A5339d.
The tvOS 16 public beta is build number 20J5366a, replacing build 20J5355f.
The watchOS 9 public beta is build number 20R5353a, replacing 20R5343e.
AppleInsider doesn't recommend installing any beta on mission-critical devices. Bugs and app issues can get in the way of getting work done, or may even lead to data loss in some cases, so backups are a must.
