General

 * Sound events


 * Options
 * A new 'Auto-jump' toggle has been added, which automatically makes the player jump when running towards a one block tall obstacle.
 * It's turned on by default.


 * Loot tables
 * A new tag  for the   function.
 * It determines the maximum amount the player can expect to receive on mob drops when using the looting enchantment of any level.


 * Particles
 * A new  particle has been added.
 * It sometimes appears whenever a gravity-affected block is first placed without a support block below.
 * Appears underneath gravity-affected blocks that generate suspended in midair, with the world generation.


 * NBT tags
 * : Determines the kind of zombie a specific zombie is.
 * 0: default, 1-5: villager, 6: husk.
 * This tag, in effect, unifies the characteristics of being a zombie, a specific zombie villager and a husk into a single variable.
 * Intended to replace the  and   tags.
 * These tags are kept for backwards compatibility, but no newly generated entities have them.


 * Debug screen
 * + shows the chunk borders around the player

World generation

 * Fossils
 * Generates 15–24 blocks underground in Desert, DesertHills, Desert M, Swampland, and Swampland M biomes. Each chunk has a $1/64$ chance of generating a fossil.
 * Composed of bone blocks and some coal ore, arranged as to resemble the skulls and spines of giant extinct creatures.
 * There are 4 variants of the skull, and 4 variants of the spine sections.

Blocks

 * Structure void
 * Used for the structure block to keep the blocks in that location.
 * Intended to be a replacement for the function barrier blocks used to convey, so they can form part of the structure itself.
 * They are invisible and have a small hitbox.
 * They are only visible when using the feature in (save) structure blocks.


 * Magma block
 * Found in the Nether, generating 4 veins per chunk between Y=27 and Y=36.
 * It has a similar frequency to blocks like andesite in the Overworld.
 * Crafted using four magma cream.
 * Mobs and players take half a heart of damage every second while touching it, similar to a cactus.
 * If the player is crouching, wearing Frost Walker-enchanted armor, or under the effect, it does not take damage.
 * If the player dies by standing on it, a new death message will appear: "[Player] discovered that floor was lava."
 * If the player dies by the block, but after being damaged by a mob or player, the death message will be: "[Player] walked into danger zone due to [Mob or Player]."
 * Removes water blocks on top when randomly ticked.
 * It emits as much light as it received from other sources when first placed or generated.
 * e.g. A magma block next to a torch will emit light at level 13, as that was the light level it received from the torch and no other sources were stronger.


 * Nether wart block
 * Crafted by filling a 3x3 square in the crafting table with nether wart.
 * It cannot be carfted back into nether wart.


 * Red nether brick
 * Crafted by placing a 2x2 checkerboard of 2 nether brick and 2 nether wart in a crafting table.


 * Bone block
 * Crafted by filling a 3x3 square in the crafting table with Bone Meal.
 * Placing it in a crafting table yields 9 bone meal back.
 * Found underground in desert and swamps as part of the fossil structure

 * Wither skeleton.
 * Mule.
 * Skeleton horse.
 * Zombie horse.
 * Donkey.

Mobs

 * Polar bear
 * Adults and children spawn randomly as passive mobs in Ice Plains, Ice Mountains, and Ice Plains Spikes.
 * When hit, the adults will attack you, the cubs will run away (very fast, similar to baby zombies).
 * Additionally, adults will always attack you when their cubs are around
 * Adults can swim faster in water than the player.
 * Drops 0–2 raw fish (75% chance) or 0–2 salmon (25% chance), each increased by 1 per level of Looting.


 * Stray
 * 80% of skeletons spawned above ground in Ice Plains, Ice Mountains, and Ice Plains Spikes biomes will be strays.
 * All spawns where the skeleton does not have a view of the sky will be normal skeletons.
 * Spiders spawned in cold biomes have a chance of having a stray riding it.
 * Acts mostly like a regular skeleton.
 * Its  tag is 2.
 * Drops are the same as skeletons, but also have a 50% chance to drop 0-1 tipped arrow of when killed by the player. With looting, chance increases to $2×level+1/2×level+2$.
 * Shoots Tipped Arrows of Slowness (0:30) at the target.


 * Husk
 * 80% of zombies spawned above ground in Desert, Desert Hills, and Desert M biomes will be husks.
 * All spawns where the zombie does not have a view of the sky will be normal zombies or zombie villagers.

World generation

 * Huge mushrooms
 * Huge mushrooms have a 1⁄12 chance of generating twice as tall as normal.


 * Plains and Sunflower Plains
 * Now have some trees in 5% of its chunks ($1/3$ large oaks, $2/3$ normal oaks).


 * Ice Plains, Ice Mountains, and Ice Plains Spikes
 * Have a lower chance of spawning passive mobs during world generation than other biomes (7% versus 10%).


 * Mesas, including all variants
 * Hardened clay and stained clay no longer generate more than 15 blocks deep, if the mesa is more than 15 blocks above sea level.
 * In addition to the normal 2 veins of gold ore below Y=32, attempts to generate 20 veins between Y=32 and Y=79.


 * Abandoned mineshafts
 * Now explicitly and abundantly spawn gold ore adjacent to the walls of the shaft.
 * Generated abandoned mineshafts above ground, will generate with dark oak wood.


 * Villages
 * Village structures are no longer restricted by biome boundaries.
 * Meaning that a village that starts in a valid biome can now spread into an adjacent invalid biome.
 * Now generate in taigas (but not variants).
 * They are made with spruce wood.
 * Savanna villages are now made with acacia wood instead of oak.
 * In savannas, acacia logs replace cobblestone in all structures except churches
 * Paths no longer generate below sea level and in non-desert villages, they are made with different material depending on the existing terrain.
 * If replacing grass blocks, the path is made from grass path blocks.
 * If replacing water, the path is made from planks.
 * Otherwise, the path is gravel on top of cobblestone (including bridges across ravines).
 * Sandstone paths still always generate in [[desert villages
 * They have a 2% chance of being a zombie village.
 * All generated villagers are instead zombie villagers.
 * There are no doors or torches in the village.


 * Caves
 * No longer turn adjacent sand blocks in the ceiling into sandstone when generating.

Blocks

 * Structure block
 * The intended purpose is revealed.
 * It is to allow the player to save and load different created structures in game, and offer a way to bundle such structures with the world.
 * The block has now four modes, each with a completely different texture than the original.
 * D, data - for chest markers and other blocks that require data (default)
 * S, save - build structure in world, tell the block where it is and it saves it to file
 * L, load - loads saved structure files, replacing blocks with saved blocks except for null blocks.
 * C, corner - for automatic size calculation
 * Are now available in item form; can be given or summoned.
 * Similarly to command blocks, its placement, destruction and modification are restricted to opped players in creative.
 * Now comes with an integrated GUI.
 * Structures can be stored, bundled and loaded per world, in the "structures" folder
 * Structures are limited to a size of 32 blocks in each direction.
 * The coordinates used by the blocks are relative to themselves.
 * When in use, it shows the outline of the structure it relates to in white
 * Can rotate and mirror blocks.
 * L and S structure blocks can be activated by redstone.
 * The game protects against maps saving arbitrary amounts of data to disk.
 * Red and blue small little cubes can be displayed in the selection area.
 * Blue is for air blocks, red is for structure void blocks.
 * Display a name tag above them indicating their mode and structure name.


 * End stone bricks
 * Are no longer craftable.

Items

 * Firework rocket
 * Recipe now produces three rockets rather than only one.

Mobs

 * Endermen
 * Can now rarely spawn in the Nether with a $1/153$ rate.

 * Can now naturally pick up netherrack


 * Magma cubes
 * Spawn about twice as often in the Nether.
 * The rate is now $2/153$, compared to $1/151$ before

Planned changes

 * Numerical block IDs
 * Limit will get removed
 * Block states
 * Can now be used in directly.
 * e.g. to set down a block of blue wool, it will be instead of.

Unconfirmed features

 * 'Observer' (BUD) block
 * Jeb indicates it will come to PC "eventually".
 * Recipes for seamless slabs and bark blocks.
 * "if we find a good recipe"
