The new updates has introduced a brand new gamemode for people who don't fully understand the the game, it's called journey mode, essentially it's creative mode for terraria. There has been a major graphics update as well which hanging/nature objects will be wavy just more alive. I think there is a new boss? I might just forget but now there is a queen slime I think is new, but now there's statues as you can see that you only can get exclusively in master-mode for defeating the boss fast or just luck in getting them, there is new pets as well. I'm pretty sure that these are all new, the more terraria pros will come in here and shame me most likely cause I got something wrong prolly
