Google finalizes Android P as Android 9 “Pie,” launching today (ars technica)

Ars technica coversthe release of Android 9 "Pie". "Android Pie is a major update for Android. Large chunks of the OS get a UI makeover in line with Google's updated Material Design guidelines. There is an all-new notification panel, a reworked recent-apps screen, new settings, and tons of system UI changes. There's support for devices with notched displays (like the iPhone X) and a gesture navigation system (also like the iPhone X). So far, battery life on the preview builds has been great, with improvements like the AI-powered adaptive battery system, a new auto-brightness algorithm, and changes to CPU background processing."
