Apple today released new beta builds for its minor updates, including iOS 9.3.3, OS X 10.11.6 El Capitan, and tvOS 9.2.2. Presumably, watchOS 2.2.2 is still on the way, but there is no longer a beta listed.
The news comes just a day after the company finally released the second iteration of its major betas, such as iOS 10, macOS 10.12 Sierra, tvOS 10, and watchOS 3. Today's builds are the fifth iteration of each of them and as the version numbers indicate, there are no new front-facing features.
The release notes say the same thing that they have throughout this beta cycle. The iOS 9.3.3 notes have the same issue with the Simulator - that it won't load iCloud Photo Library - and an issue with Dictionary when upgrading to an iOS 9 GM seed. In other words, it's nothing that would affect the end user.
As usual, the tvOS 9.2.2 release notes are the only ones to formally state that there are known issues. The OS X 10.11.6 El Capitan notes say absolutely nothing about what's in it.
If you're on the El Capitan beta, you can get OS X 10.11.6 by checking for updates through the Mac App Store. iOS and tvOS might be a bit trickier. For iOS 9.3.3, you'll need to either be on the public beta or flash the image through iTunes; however, for tvOS 9.2.2, you can only get the new beta by flashing through iTunes.
