Somewhat unexpectedly, Apple this morning issued new developer-only betas of iOS 10, macOS Sierra, tvOS 10 and watchOS 3—a mere week after posting their respective fourth beta. While Apple's release notes for iOS 10 beta 5 (build number “14A5335b”) mention no new features as we inch closer to a Gold Master, there are a few tidbits and tweaks to wet your appetite.
Aside from other changes, for instance, iOS 10 beta packs in a new lock sound and lets you download apps from the App Store after a reboot without needing to re-authorize Touch ID purchase with your Apple ID password.
