what do you think about the new update 1.17
I like the new beautiful CAVES : D

If I had a Minecraft dev in front of me I would say 1 thing. Optimize the game. Help the game survive instead of killing it.

the glow squids though, why don't they glow. Also colored lighting would be cool like if you put a light source behind stained glass and the light changed colors.

i don't played yet but i think that is a good update, but dont have so much new things
