Apple today started rolling out the sixth public beta of iOS 10, the next version of its mobile operating system. The release comes four days after Apple released the fifth public beta, making it the shortest gap so far between public beta releases for iOS 10.

Apple first unveiled iOS 10 at its WWDC conference in June and introduced the initial public beta last month. Apple has not been explicit about what’s changing in these public beta updates, but generally they come with bug fixes and new features.

The final version of iOS 10 is due out this fall, along with new iPhones and reportedly also a new MacBook Pro and a new Apple Watch — with macOS replacing the OS X operating system for Macs and watchOS 3 for the Watch.

This public beta update can be installed on the iPhone 6s, iPhone 6s Plus, iPhone 6, iPhone 6 Plus, iPhone SE, iPhone 5s, iPhone 5c, iPhone 5 12.9-inch and 9.7-inch iPad Pro, iPad Air 2, iPad Air, fourth-generation iPad, iPad mini 4, iPad mini 3, iPad mini 2, and sixth-generation iPod Touch.

If you’d like to install the newest public beta, you can open up Settings, hit Software Update, and hit Download and Install. To install it, you’ll need to have your iOS device connected to a power source or have at least 50 percent battery life. You’ll also need to be part of the Apple Beta Software Program.
