Apple fans who want to get a glimpse of iOS 10 and macOS Sierra before their public release later this fall will finally get the opportunity to install the new software today.

Coming just two days after the release of the second beta of iOS 10 and macOS Sierra to developers, Apple is now letting members of its public beta program install the new software, which debuted last month at WWDC.

More than 50 changes have been discovered by developers, affecting everything from Apple Music to widgets. A lot of the changes are very minor UI tweaks that would probably go unnoticed by many users, but Apple has also added some huge additions to the Home button, Messages, Notification Center and more.
