Google on Monday pulled the wraps off the latest version of its Android mobile operating system. Version 8.0 Oreo has a number of improvements over 7.1 Nougat, the previous release of the OS. Google has tweaked Android's notification feature, for instance, so when an app has notifications pending, a dot appears in a corner of the program's icon. Press the dot and a window will pop up showing the notifications, which can be cleared with a swipe. In addition, there's an Instant App feature for entering new apps directly from a browser.
