Did you expect to wake up to a new version of Android this morning? Probably not. But that's exactly what you're getting, and Google's letting the information fly fast and hard (... and in some cases, slightly before we expected) about the latest iteration of their mobile OS, at this time only known as "N." Like previous... previews... N doesn't have a version number or name yet, but it's chock-full of new features for users and developers alike, and the list of those features will grow as we near the final release. Let's break down the key facts.

• Preview images: Android N preview images will be available today for the Nexus 6, Nexus 5X, Nexus 6P, General Mobile 4G (Android One), Nexus Player, Nexus 9, and Pixel C.
