Apple has officially seeded the fourth developer beta for iOS 9.3.3, as well as the latest seed for public beta testers. It’s available for the iPhone, iPod touch, and iPad, and it’s available as an over-the-air update for devices that have been registered to run beta software.
iOS 9.3.3 is a relatively small update, focused on bug fixes and behind-the-scenes tweaks for performance. Apple released iOS 9.3 in late March of this year.
In addition to iOS, Apple also seeded new betas for tvOS and OS X on Tuesday. The betas are available to registered developers and testers, and can be installed via OTA in tvOS, for those with the latest beta profile, and the Update tab in the Mac App Store.
OS X 10.11.6 and tvOS 9.2.2 are also minor updates, featuring mostly bug fixes and improvements. Again it seems like Apple is just looking to tighten things up as it moves on to the next versions. macOS Sierra and tvOS 10 are expected to land later this year.
