The upgrade version is V188.8.131.52.NBCMIEI for the Mi Max and is around 1.5 GB in size. The Prime version should get V184.108.40.206.NBDMIEI but the package is essentially the same.
MIUI 9 brings to Xiaomi users new features like Split Screen, Search for Apps, Dual Apps and a new assistant, accessible with a left swipe from the home screen.
