Apple today released watchOS 3.2.2, tvOS 10.2.1, and macOS Sierra 10.12.5 to the public. The updates feature various security patches, bug fixes and performance improvements, and come after more than a month of beta testing.
There have been no major changes or features spotted in tvOS 10.2.1 or watchOS 3.2.2 either. However, Apple says that macOS Sierra 10.12.5 fixes an audio issue with USB headphones, enhances Mac App Store compatibility, and adds support for media-free installation of Windows 10 Creators Update using Boot Camp.
macOS 10.12.5 can be downloaded and installed from the Mac App Store. tvOS 10.2.1 can be installed through the Settings app on the set-top box. watchOS 3.2.2 can be downloaded through the dedicated Apple Watch app on the iPhone by going to General -> Software Update. To install the update, the Apple Watch must have 50 percent battery.
These will probably be the last public updates released before we get a preview of the next major versions of each platform at WWDC next month.
