Here are the updates for Samsung Galaxy Note 8 and there is new software, a new update in Asia for units on the market. What does the update file contain? Android fixes and the October security code.
Specifically, the variants of the Chinese version and Hong Kong (SM-N9508 and SM-N9500) receive the update. There is currently no information as to whether we will soon see a corresponding update for other versions of the phone.
As is common with OTA deployments, the alert may take a while to appear on your device. For those outside of China and Hong Kong, we assume that it is a matter of time for the information to reach you as well.
