This is a list of Java Edition 1.10 development versions.
16w20a
16w20a is the first snapshot for Java Edition 1.10, released on May 18, 2016,[1] which adds bone, magma, and nether wart blocks; husks and strays as zombie and skeleton variants, respectively; polar bears; and fossils that spawn underground.
Additions
Blocks
- Crafted by filling a 3×3 square in the crafting table with bone meal.
- Can be crafted back into 9 bone meal.
- Found underground in desert and swamps as part of fossils.
- Found in the Nether, generating 4 blobs per chunk between y=27 and y=36.
- Crafted using four magma cream.
- Mobs and players take 1 damage every second while touching it, similar to a cactus.
- If the player is sneaking, wearing Frost Walker–enchanted armor, or under the Fire Resistance 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 entity".
- Removes water blocks on top when randomly ticked.
- It produces smoke particles under the rain.
- It emits as much light as it receives from other sources.
- 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.
- If the torch were to be removed then it will search for the next brightest source of light; if no source is found then it will not produce light.
- 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.
- Crafted by filling a 3×3 square in the crafting table with nether wart.
- It cannot be crafted back into nether wart.
- It is broken by flowing water or lava, like most plants are.
- Crafted by placing a 2×2 checkerboard of 2 nether brick and 2 nether wart in a crafting table.
- 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 void.
- Allows for empty spaces in a structure.
- Unlike air, it will not overwrite blocks where it is loaded.
- Example: If the player loads a 2-block-high structure with air at the top and a structure void at the bottom into a 2-block-high area of stone, the top block will become air but the bottom will stay stone.
Items
- Added cat egg: Light brown with brown spots.
- Added donkey egg: Dark brown with light brown spots.
- Added elder guardian egg: Light yellow-white with purple spots.
- Added husk (new zombie variant) egg: Brown with cream colored dots.

- Added zombie horse egg: Dark green with light green spots..
Mobs
- 80% of zombies spawned above ground in desert biomes, and their variants, will be husks.
- All spawns where the zombie does not have a view of the sky will be normal zombies or zombie villagers.
- Behaves mostly like a regular zombie.
- Its
ZombieType
tag is 6. - Does not burn in sunlight.
- Can spawn as a baby or as a chicken jockey.
- Applies 7 seconds of hunger when attacking in Easy, 14 in Normal and 21 in Hard difficulty.
- Visually 2 pixels taller than zombies, but has the same hitbox.
- Adults and cubs spawn randomly as passive mobs in ice plains, ice mountains, and ice plains spikes.
- When hit, the adults will attack the player, the cubs will run away (very fast, similar to baby zombies).
- Additionally, adults will always attack the player when their cubs are around.
- Can swim faster in water than the player.
- Cubs will follow their parents.
- Drops 0–2 raw fish (75% chance) or 0–2 salmon (25% chance), each increased by 1 per level of Looting.
- 80% of skeletons spawned above ground in ice plains biomes, and their variants, 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
SkeletonType
tag is 2. - Drops are the same as skeletons, but also have a 50% chance to drop 0-1 tipped arrow of Slowness 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.
World generation
- Generates 15–24 blocks underground in deserts, swamplands, and their variants. 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.
Command format
- ZombieType: 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 IsVillager and VillagerProfession tags.
- These tags are kept for backward compatibility, but no newly generated entities have them.
- Added
block.enchantment_table.use

Blocks
- Are no longer craftable.
- 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 and new textures.
- Has four modes:
- Save - build structure in world, tell the block where it is and it saves it to file.
- Load - loads saved structure files, replacing blocks with saved blocks except for structure void blocks.
- Corner - for automatic size calculation.
- Data - for chest markers and other blocks that require data (default).
- 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 structures before they are placed.
- Small red and blue cubes can be displayed in the selection area.
- Blue is for air blocks, red is for structure void blocks.
- Save and Load structure blocks can be activated by redstone.

- New NBT tags
powered
: Whether or not the structure block is currently being powered with redstone.showboundingbox
: Whether or not the bounding box of the structure is being outlined.showair
: Whether or not air blocks are indicated within the structure.
Items
- Recipe now produces three rockets rather than only one.
Mobs
- Can now rarely spawn in the Nether with a 1⁄153 rate.
- Compared to 100⁄153 for zombie pigmen.

tag.
World generation
- Ice plains and variants
- Don't spawn any other passive mobs than rabbits and the new polar bears anymore.
- Also have a lower chance of spawning passive mobs during world generation than other biomes (7% versus 10%).
- Mesas, including all variants
- Terracotta and the dyed forms of terracotta 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 blobs of gold ore below Y=32, attempts to generate 20 blobs between Y=32 and Y=79.
- Generate the new type of mineshafts, described below.
- New mineshaft type that generates in mesa biomes (including all variants).
- Placed so that the midpoint of the structure is near sea level, rather than so that the top is 10 blocks or more below sea level.
- Uses dark oak wood for wooden structures.
- New NBT tag
MST
on mineshaft structure pieces to indicate the type. 0 is the traditional mineshaft, 1 is the new mesa mineshaft.
- Features generate differently if above ground (i.e. the sky light where they generate is 8 or more). This is not dependent on mineshaft type.
- Cave spider spawners no longer generate if sky light is 8 or more.
- Various wooden pieces no longer generate if the block above is air and/or if sky light is 8 or more.
- Rails in corridors are more complete if sky light is below 8.
- 90%, versus 70% in 1.9 and in above-ground corridors.
- Now have some trees in 5% of its chunks (1⁄3 large oaks, 2⁄3 normal oaks).

- 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 log.
- 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 or lava, 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, determined by
Zombie
NBT tag inVillage.dat
.- All generated villagers are instead zombie villagers.
- There are no doors or torches in the village.
Command format
