This means that the rollout has begun for the Nexus 6, Nexus 9, Nexus Player, Nexus 5X, Nexus 6P, Pixel C tablet, and even the Android One devices. Google does note that the rollout could take "several weeks" and carriers could get in the way, so you may not see the update hitting your device right away.
Android 7.0 is a substantial update that has a number of great new features, including tweaks to Doze to help you save battery life while on the move, new emoji, better Quick Settings, multi-window mode, expanded direct replies from notifications, and a few security improvements as well. Those getting the software update won't, however, be getting the new seamless update feature, and the official Android Nougat page makes it seem like not all devices that ship with Nougat will get it either, so we'll have to keep an eye on that.
Let us know in the comments if you're seeing the final Android 7.0 Nougat update hitting your device!
