Typing "/report [username]" while playing will flag the possible offender's account for Ubisoft to look at, and if the gaming company determines nefariousness is at play they'll get a three day suspension. Repeat offenders? That's grounds for a permaban. It's a reasonable expectation that if this doesn't curb the cheaters, the three-day time-out will give way to nothing but permabans a la what Ubisoft did with Rainbow Six: Siege hackers in January

There are some pretty welcome glitch fixes en route as well. Those address issues where missions wouldn't start, wouldn't complete, non-player characters are able to shoot through walls and glitches where folks could get stuck in place on a piece of architecture in the environment, among other bugs.
