Apple today released the third beta of iOS 10 to developers for testing purposes, two weeks after seeding the second beta and more than a month after first unveiling the new operating system at its 2016 Worldwide Developers Conference.

Today's update is available as an over-the-air download to those who installed the first beta or the beta configuration profile and it's available for direct download through the Apple Developer Center.

iOS 10 is a major iOS update with a host of new features and design tweaks, including a new Lock screen experience with 3D Touch-enabled notifications, a more easily accessible camera, a redesigned Control Center, and a new widgets screen.

Messages has been entirely overhauled with features that include background animations, bubble effects, Digital Touch, handwritten notes, Tapback replies, predictive emoji, and its own dedicated App Store, and Photos has gained impressive facial and object recognition capabilities along with a Memories feature for rediscovering forgotten moments.

Over the beta testing period, Apple will tweak the features introduced in iOS 10, and in iOS 10 beta 2, Apple launched the Messages App Store and added organ donation signup functionality, among other changes. New changes in beta three will be listed below.

iOS 10 is currently available to developers and public beta testers, with a full public release planned for the fall. For full details on iOS 10, make sure to check out our iOS 10 roundup, and for details on what's new in beta 3, make sure to take a look at our dedicated tidbits post.
