Do you mean note 9 ? for note 9 there was the updated security patch plus some camera updates like adding the night mode and the new charging animation when you connect your phone to a charger, that's all I noticed so far.
latest update for note 8 UAE/XSG (june security level, even though its released in July) add Wifi calling and VoLTE to my device, although that depends on your telecom carrier (had to contact Batelco here in Bahrain to activate both features on my line). It also fixed HDR issues, AND 40-50 mins SOT of battery life. best update yet! and a minor change is that, now when a charger is connected, battery percentage is displayed in a white ring mid screen.
