For a long time, developers and participants of the public beta program worked on finding bugs in iOS 10.3.2, macOS 10.12.5, tvOS 10.2.1 and watchOS 3.2.2. All work was done for this moment. New versions of the software have been released and are available to all owners of compatible devices.
You can proceed with the installation. With these updates, Apple’s devices will become more secure, and stability and performance should improve. Updates will not bring new features. All the engineers’ attention was focused on working on the bugs.
We recommend that you install the released versions. Developers and amateurs of using beta versions go into standby mode. Most likely, soon enough Apple will release beta versions of the following OS.
