Google has done its promise for delivering a release for the developer preview of beta tester of Android Nougat 7.1 before the end of October 2016. If you have Nexus 5X, Nexus 6P or Pixel C, then you will be able to access it, but Google will not release it for other devices until end of November 2016. It is expected that final public release will not be available before mid of December 2016. If you have any of the above mentioned devices, then you can easily get an OTA update, but you should be enrolled before getting beta program of Android.
Meanwhile, if you don’t originally make apps, you can also download the preview, but its features only provide benefits to most of the developers. Alongside VR support of Daydream, it provides the functionality in making app shortcut and circular launcher icons in order to match the look for new Pixel phones of Google. It was also mentioned that it has other features for ordinary users such as a restart button in the power menu. It has the capability to support image keyboards and allowing users to insert stickers and GIF images in the apps. You can also perform a manual update by flashing a system image if you need to test 7.1 without enrolling to beta program of Google.
