by things to do there's underwater dungeons and if you're a resource pack maker you can now make different block models
there's also some new materials and you can now kill sheep for food
also bunnies
that's really it i think
Rabbit's Feet make you jump higher when brewed.
There's a lot of more things, too. For example:
Diorite, andesdite and granite for building materials
Lapis is now required to enchant, but now enchanting tells you a hint about what you're making beforehand
Almost everything is obtainable, and coarse dirt (non-spreading), chiseled stone bricks, moss stone/stone bricks, and cracked stone bricks all have new recipes
New wood-colored doors, fences, and an iron trapdoor
You can put buttons on ceilings
Banners
Red sandstone to go with the new red sand
Bouncy slime blocks
Armor stands to... hold armor
Smarter villagers
Soak water with the new sponge, and empty it by smelting it.
