I am currently playing the snapshot right now. I'm writing as I discover new stuff. I threw some redstone circuits into a superflat world and they all seemed to work. The Purpur blocks and Endstone Bricks look interesting. Theres an awesome new mob called a Shulker that looks like a Purpur block. When you walk near it the block opens up, showing a wierd head that shoots projectiles at you that make you levitate! New potion arrows PLUS spectral arrows that make mobs more visible (gives them an outline) Added beetroot stuff from PE and Chorus fruit (?) DRAGON HEAD! Dual wielding! Press F to switch! This adds another spot in your amor area that you can place tools in. I can figure out how to switch arrows Always uses same type NEW /effects! minecraft:glowing (spectrum arrow effect) minecraft:levitation (shulker) /summon ShulkerBullet /summon Shulker iron bar cages around some end crystals. Dragon still heals from them. There's probably more I haven't found yet though.
