It’s been nearly two months since Google last released a new Android O Developer Preview update, but today that drought is finally ending.

Android O Developer Preview 4 is now rolling out. If you’ve got a device that’s enrolled in the Android Beta Program, you should receive this update in the coming days. You can enroll in the Android Beta Program right here if you’re not already in it. You can also manually flash this update by downloading your device’s system image.

Google says that Android O Developer Preview 4 is a release candidate build, which means that developers can use it to finish testing their apps in time for the public Android O release later this year. This update includes final system behaviors, more bug fixes and optimizations, and the final APIs.

The public release of Android O is slated to happen in Q3 2017.
