Apple has released the eighth beta of iOS 10 to developers and the seventh beta for public beta testers. The finished version of the operating system is due this fall.
Developers can download the beta through the Apple Developer Center or the Software Update mechanism in the App Store. If you're not already signed up for the public beta program, you can do sign up here. The public beta program is free, but remember: beta software is unfinished software so use with care.
