Map pins will only show a mob with the mount icon if you're eligible for that mount (unless it's one of the BoE mounts, which are always given priority)
Similarly, announcement sounds and screen flashes will only use their mount variants for mounts you don't have yet or BoE mounts
Right-click menu on map pins give you a shortcut to open the achievement associated with that mob
A zonewide point-of-interest means the same thing as vignette: you're definitely eligible to loot that mob
Zereth Mortis: assorted improvements to treasure/rare requirements
Maw tweaks:
Tea for the Troubled mobs will show as "completed" rather than "killed" in tooltips
Minions of the Cold Dark is tracked in tooltips
Legion: added some missing loot and cleaned up some data (legendaries had snuck in where they shouldn't...)
