Google has released the final and updated version of the Android O Developer Preview. As usual, the preview is also available as an over-the-air update for the users of Pixel, Pixel XL, Pixel C, Nexus 5X, Nexus 6P and Nexus Player, and if you are brave enough to use an unreleased beta version of an OS, enroll yourself here. Android O, which would be version 8.0 in the series of the popular mobile operating system, after receiving the fourth and final developer release is almost ready for the Public Beta version now.

While we don’t know yet if the final preview has any significant UI changes or not, and since the APIs were released with the third update, we are expecting this one to be more stable so that the developers can test their apps before the final version is delivered to the users. Even though the new version of Android does not contain a ton of new features for the users, significant ones in the form of notification channels and dots on app icons to alert you of notifications, picture-in-picture video playback, a streamlined settings menu, can be surely found.

Major news related to this release is the availability of a stable version of the Android Studio Library (version 26). Android Support Library, in simple words, is a collection of libraries developers can add to their apps to bring some of the latest Android features to an app, regardless of the host OS version.

An interesting thing to note here is, that Google hasn’t provided any official name for its upcoming Android software. However, if you repeatedly tap on the Android version in system settings, it shows an Octopus. What happened to delicious food treaties and Oreo?

With the fourth preview underway, we can be sure about the fact that Google’s schedule is pretty much on track before it starts rolling out the official updates for non-Pixel/Nexus handsets later this summer.
