We also now get Sims Delivery Express. Free goodies for the game.

Skin-tone variation, rounded walls, floor-platforms and heterosexuality are among the fun newfangled novelties.

No, honestly. Still the same buggy mess it always was and always will be apparently. :/

I'm assuming you mean since mid-late 2021?
Some of the most notable new features are:
Pronouns
Sexual and Romantic Orientation
Body Hair
Werewolves
Curved walls
Highschool Pack
Wedding Pack
Goth Makeover
Scenarios (Built-In Challenges)
Wants and fears
Some from earlier 2021 are:
New hair colors
Bunk beds
Farming pack
Ponds

I would recommend browsing the forums. Probably some obvious ones that I missed.
Happy Simming! :)

Lol. Guess I'd better turn off notifications for this thread. ?

Let's see: werewolves, bugs, cottage living, bugs, a bunch of kits, my wedding stories, bugs, & high school years off the 5top of my head.
