Dwarfs got a whole wheel (134 spokes?) of emotions that pretty much negated tantrum spirals.
Elves become overpowered due to 1 tile = 1 log trees became multi-tile tress = elfloads of logs that if it falls on your dwarf, it can maim and kill, as well as punch holes in your constructed ceiling / floors but that last part was patched. But the elves themselves are just the same wimps. it's their tree-kin that got buffed.
Locations replaced the meeting hall / dinning room to provide social interactions: Taverns, Temples, Library, and now maybe Museums are set as meeting zones that satisfy certain emotional needs. Green text is optional need while idle; purple text is must need disregarding other labors or military commands.
With taverns, you get visitors, including animal-man who may petition to "reside" in your fort, and then to become a "citizen" of your fort where they can do any dorf labor. Mercenary visitors can be included in as squad members that is captained by a current citizen of the fortress.
Scholars may visit and write books or steal book; or you can assign your own citizen to be a useless scholar to write a book. Scribes you assign copy books in.
Temples can be dedicated to specific deities; and upon toppling statues can get the toppler cursed with vampirism, or lychantrophy.
Sieging army now comes from existing world population instead of our of the void; which then adds issues to the army's pathing to sieging your fort in a regular and consistent manner; or worse, lack of sieges.
Now, the latest is artifacts. Where you can raid places in the world, stealing stuff (mostly books) and can piss off other civs to declare war. Sometimes your raiding part gets captured, die, or just get lost and never to return.
