While virtually all compatible handsets out there are still waiting to receive the first Android 7.0 Nougat update, its first major update makes its appearance in the Google Play Developer Console. Obviously, this is merely a mention of this upcoming Android version and nothing more.
As we already know, Google is changing the way Android gets updated starting with Nougat. Since they are introducing Maintenance Releases (MR) instead of various minor updates, it would not be a surprise to see Android 7.1 Nougat coming up as Android 7.0 MR1. Unfortunately, nothing is official yet, so the first Maintenance Release patch could be Android 7.0.1 Nougat, Android Nougat MR1, but could end up launching under a completely different name as well.
Strange enough, the analytics logs of various websites and apps already show Android variants such as 7.1, 7.10, or 7.1.1. We will probably hear more in the coming weeks since Nexus devices are already receiving Android 7.0 Nougat and its first Maintenance Release patch should not be too far.
