There is no Andesite, Diorite, Granite, Deepslate, Tuff, Dirt, Gravel, Deepslate Ore of every varient, Coal Ore, etc 

There is Diamond ore, redstone ore, lapis lazuli ore, gold ore, copper ore, iron ore, emerald ore, lava, water, bedrock, and stone

I'm not 100% sure this is a bug but in Minecraft Live they mentioned deepslate and deepslate ores, and tuff spawning below Y=0 and past about Y=0 it doesn't spawn

This is in the experimental Caves and Cliffs experiment thing but I still think it's a bug or it hasn't been fully finished yet 

although I still think it is a bug but if I'm wrong let me know otherwise I'll never know and it might never be solved

when you throw items in lava the sound of the items burning doesn't play 100% of the time it plays 1% of the time, walking on anvils makes no noise with 0% chance of making footstep noises, 1% of all fall damage sounds are delayed after falling atleast 4 blocks, if you take fall damage 2 times in a row (right after taking damage) if your fast enough you don't take any fall damage, entities in boats take fall damage after falling in a boat on land, Hoglins sometimes damages you in peaceful if your close enough and hit it

All shown here are in as much detail as I can possibly give at the moment I may edit this when I have more information
