Developers are more inclined to bring its custom build for various devices based on the latest Android version. Google released the official 8.1 Oreo for all of its Nexus and Pixel phones with the December 2017 Security Patch. As of recent, Android 8.1 Oreo for many Xiaomi devices are showing up including the first build for the Redmi Note 3.
Thanks to developer xyyx, we are now seeing an Nitrogen OS 8.1 Oreo build for the Xiaomi Redmi Note 3. This one is a custom ROM based on Android v8.1.

The ROM is called NitrogenOS.
