Gameplay

Dominant hand option

An option for players to change their dominant hand on their player model.
- Under "Skin Customization".
Changes the orientation of the offhand slot in the hotbar (left often suits right-hand players better and vice versa).

Dual wielding

Players can now use both hands at the same time to do different actions, with the left and right mouse buttons.
- For example, if a player has a pickaxe in their main hand and a torch in their other hand, right clicking places the torch.
  - This happens because a pickaxe lacks a right click use, and therefore the game tries to then treat the other item as if it's being right clicked.
  - The player cannot click both buttons at the same time.
- This is achieved through an extra inventory slot called the "offhand" slot.
  - Pressing F (by default) switches whatever item is selected in the hotbar with the item in the offhand (including no item).
  - The offhand slot is displayed next to the hotbar when it's not empty (left for right-hand players and vice versa).
    - It's also available in the inventory screen.
Only the main hand can be used for attacking.
- Even bows can't be used in the offhand.
Bows can be used when something else is in the offhand.
- Arrows in the offhand take priority over arrows in the rest of the inventory slots.
The offhand model is invisible in first person view, while it's empty.
Some attributes and enchantments apply to the offhand item, while others do not.

Levitation
- Received when the player is hit by shulker projectiles.
- Makes player involuntarily float high into the air.
  - Can be used to get to higher places.
- Listed as a negative effect, due to the potential to kill from fall damage.
- Higher levels of Levitation result in faster floating, except for the last two:
  - Level 255 does nothing.
  - Level 254 results in slow fall (similar to lunar gravity).

Glowing
- Received when players or mobs are hit by spectral arrows.
- Makes player's outline glow, seen even through non-transparent blocks.
  - The outline includes the models of the currently held items.
- Listed as a negative effect, because it prevents players from hiding from other players.
- It becomes colored differently if the player is part of a team, to match its team color.

Changes

Blocks

Dead bushes

Now drop anywhere between 0–2 sticks when broken without shears.

Doors

Changed the shading on acacia, birch, dark oak and jungle doors.

Fire

The block states flip and alt were removed, and the integer state upper was reimplemented as the byte state up.
- This reduced the number of states representing fire from 3072 to 512.

Glass panes and iron bars

Are now 2×2 pixels in footprint if no blocks connect to them.
- This is compared to the big cross configuration that was the default.

Pressure plates

Now have a slightly thinner item model.

Redstone wire

Model was changed somewhat, resulting in subtle appearance differences.
- Before:
- After:

Stairs

Are now rotated 90° in the inventory.

Trapdoors

No longer require supporting blocks.
- Therefore they can be moved by pistons freely.
An open trapdoor may be climbed like a ladder if it is directly above one and on the same side of the block.

Items

Bows

The bow in the hotbar now shows an animation for drawing back an arrow.
Arrows in the off hand are prioritized over arrows in the rest of the inventory slots.

Ender pearls

Can now be thrown in Creative mode.

Fishing rods

Casting fishing rods now has an animation in the hotbar/inventory.

Item models for chest-like blocks

Unlike other blocks, chests, trapped chests and ender chests have their item model rotated, to have the front face in view of the player.
- This made it easier to distinguish between trapped and regular chests while being held, since only their front face is different.

Maps

Now display as a mini map when held in the off hand, or if the offhand slot is occupied.
- The (old) large version is visible only when held in the dominant hand with both hands-free.

Potions

Mixed potions' colors now blend.
Numeric IDs are no longer used. Instead, a "Potion" tag is used.
- e.g. /give @s minecraft:potion 1 0 {Potion:"minecraft:swiftness"}
Splash potions now have a separate data value and ID name and can be created from all potions, including water bottles.
Added Mundane, Thick and Awkward potions to the Creative inventory.
Glowstone dust or redstone can no longer be added to extended or tier-II potions, respectively.
Most recipes for potion of Weakness were removed; only brewing from a water bottle remains.
Potion of Slowness can no longer be brewed from a potion of Fire Resistance.
Potion of Harming can no longer be brewed from a potion of Water Breathing.
Splash potions now have the same duration as drinkable potions.^[2]

Mobs

Chickens

Can be led and bred with melon seeds, pumpkin seeds, and beetroot seeds, in addition to regular seeds.

Ender dragons

Similar to the one on Legacy Console Edition.
The dragon can be re-spawned indefinitely by creating a creeper face configuration out of clay in the End.
- Subsequent dragons spawn new gateways, but don't drop XP or create new dragon eggs.
The dragon AI and attacks has been changed:
- Breathes fire/purple particles on players and mobs, while on top of the portal.
- Drops fireballs on top of the player.
- Defends the obsidian pillars more, the further the fight progresses.
The dragon flies and stops over the portal sometimes, only then can the last blow be dealt.

Endermen

Remain aggravated towards the player despite being in contact with water.
Drop the block they were holding when killed.

Pigs

Can be led and bred with potatoes and beetroots, in addition to carrots.

Skeletons

Have an animation for lifting up and drawing back their bow.

Villagers

Farmer villagers now harvest beetroot.

Non-mob entities

Armor stands

Can now be summoned to dual wield with commands in Creative.

Projectiles

Slightly altered the path of projectiles.^[3]

World generation

The End

A set amount of differently-sized obsidian pillars are arranged in a circular fashion.
- The tallest pillars have iron bars around their ender crystal to deflect projectiles.
The exit portal is pre-generated at the center of the island, but without the dragon egg and portal blocks.
Now generates a great amount of islands in every direction from the main island, though separated from it in all directions by an empty gap of about 1,000 blocks.
- Mini islands generate between the center and main islands.
- End islands and mini End islands have chorus trees spread throughout them.

The Nether

Removed the fog in the Nether.

Villages

Farms now include beetroot crops.

Command format

NBT format

Tag Equipment (under Living) has become deprecated.
Tag DropChances (under Living) has become deprecated.

Gameplay

Crosshair

No longer shows the crosshair in 3rd person view.

Inventory

Rearranged the Survival inventory and the Creative "Survival tab" to accommodate for the new offhand slot.
Unified the orientation of many items in the inventory.

Status effects icons are now displayed on the HUD on the right hand corner, instead of just in the inventory (similar to Pocket Edition).
- They are ordered by the time of infliction from right to left.
- Positive effects are on the top row and negative effects on the bottom row.
- Effects that are about to run out, blink.
  - They blink faster when they are closer to running out and start fading away.

General

Attributes

CustomNameVisible:true makes the name tag on mobs show in the same way as on players.
Entities can now be summoned straight to teams: {team="TeamName"}.
DropChances and Equipment tags are no longer used.
- ArmorItems, HandItems, ArmorDropChances and HandDropChances are used instead.

Bosses

Proper support for multiple bosses' health bars, so they show at the same time without obstructing each other.

Damage tooltips

Items can damage differently based on where they are placed to (main hand, offhand, armor slots).

Death messages

Death messages now are displayed on the player's death screen as well as in the chat.

Models

Different models/textures can be used for each different damage values, item states, and whether the item is held in a different hand.
- This works on compasses, clocks, and anything that can have a durability bar.
- It also contains additional tags for bows and fishing rods.
Models can be put together based on block state attributes, such as fences.
- As a result, the vanilla set of block models was reduced by almost 300.
Block model JSON is now strict: comments and quote-less identifiers are not allowed.
display tag defaults have changed, and the thirdperson and firstperson tags were replaced with thirdperson_righthand, thirdperson_lefthand, firstperson_righthand, and firstperson_lefthand.
parent and elements tags can coexist now, though the top level elements tag overwrites all former ones.
UV is now optional, and if not supplied it automatically generates based on the element's position.

Options

Removed the Broadcast Settings section, as well as Twitch integration as a whole.
Removed Super Secret Settings and Alternate Blocks from video settings.

Resource packs

Updated resource pack pack_formatto 2 as the following has changed:
- Changes in the model system, such as item tags, multipart, and changes to display tags.
Older resource packs require user acknowledgment to use.

Now comes from /assets/structures.

Additions

General

Scoreboard

Added /scoreboard players tag ...
- Players can add and remove tags for any entity based on NBT data of that entity/player.
  - For example /scoreboard players tag @a add test {OnGround:0b} adds the tag "test" to all players that are in the air.
- Tags can be accessed by using the parameters after the selector; /give @a[tag=test] stone 1 gives 1 stone to all players that have the tag "test".
- Players can use /scoreboard players tag <player> list to see what tags are on an entity (Note that in this current version, players can't use tab to get "list").
- Tags are stored in the playerdata file as strings, not in the scoreboard files.
  - This means that any tag the player binds, has to be bound to an existing online player or an existing entity.
  - Unlike objectives, tags cannot be displayed on the sidebar or anywhere else.
    - Only via the list subcommand can you see which tags an entity has.
Added three new objective types: XP, hunger and oxygen.
- "xp" can be used to track the players exact amount of XP points.
- "food" can be used to track the hunger level of the player (ranges from 0 to 20).
- "air" can be used to see for how long the player has been underwater.
  - Starts at 300 (out of water) and then decreases 1 per tick as long as the player's head is underwater (resets when the player exits the water).
  - The Water Breathing effect freezes the timer and the Respiration enchantment slows down the countdown each time more with each level.

World selection screen

Now displays a thumbnail per world showing a glimpse of the world (it takes a screenshot when player has just created or opened it for the first time in this snapshot or higher).
- When the world hasn't been opened in snapshot 15w32b or before, or if the game couldn't make a screenshot thumbnail, a gray-scale image is displayed.
- The thumbnail is saved in the world folder under .minecraft/saves with the name "icon.png".

Changes

Now flies over the portal and dies if the final hit is applied elsewhere.

Shulker

No longer teleport by themselves if NoAI is set to 1.
Can now be teleported using /tp or /spreadplayers.

- It also warns if a world was played in a newer version of Minecraft before, telling the player that the world may corrupt, if they open it in an older version.
  - The version number now displays in red if it has been played in a newer version before.

- Entities that walk into the cloud get the corresponding effect.
Has variants for every potion type, and works with potions whose effect are instant, like Harming.
Brewed with dragon's breath and the corresponding splash potion.
- The only way to do this is to brew the splash potions from normal potions and leave them in the slots of the brewing stand. Then add the dragon's breath.
The cloud duration can be controlled through a data tag.

Command format

- The spawnable item from a spawn egg is now addressed by a datatag: give @p spawn_egg 1 {EntityTag:{id:"Creeper"}}.

Mobs

General

The HealF float tag has been renamed to Health.
- As a result, the original Health tag is now a float type rather than short.

Now shoots the previously added ender acid entities.
- A fireball-like projectile.
- On impact it spawns dragon breath and lights the ground on fire.
  - The dragon breath acts like a lingering potion, creating a special entity cloud.
    - Players in the cloud get damaged.
Arrows get deflected and set on fire while the dragon is on top of the portal.

Command format

NBT format

CommandStats can be used to obtain the number of scoreboard tags an entity has via QueryResult.

Additions

Items

Shields

Used for blocking incoming attacks.
- Holding right click while being attacked reduces damage on the player and the durability of the shield.
  - This works when the shield is either in the main hand or in the offhand.
    - The player can hold 2 shields at once, but it does not affect the damage taken.
Can be combined with banners of the same base color to transfer its pattern.
- This does not consume the banner.
The player cannot attack while blocking.
Crafting recipe: One column of wool (of the same color), one column of planks (any kind), an iron ingot in the middle of the last column.
Can only be repaired on the anvil.
- Requires planks to repair.
Cannot be enchanted on the enchanting table, but can have Unbreaking added via an enchanted book.

Changes

Blocks

Brewing stands

Can now accept splash potions into the lower slots.
Before, the only way to get splash potions in a brewing stand was to brew them from normal potions and leave them in the slots.

Ender crystals

New BeamTarget tag.
- Used to specify a custom target for the beam.
- Example: /summon EnderCrystal ~ ~1 ~ {BeamTarget:{X:1,Y:2,Z:3}}.

Items

Fire charges

Now shoot as ender dragon fireballs when ejected from a dispenser, appearing purple and casting dragon's breath.
- Before this, they had shot as blaze fireballs.
- This was reverted in 15w44b to shoot as blaze fireballs once again.

Swords

Can no longer be used for blocking, since shields now serve that function.

Mobs

Respawned dragons now drop 500 experience.
Respawning the dragon now regenerates the circle of pillars, including the ender crystals and iron bars.
- Explosion particles appear at the tops of the pillars as they are being rebuilt.
- All end gateways are left intact.

Creepers, skeletons, & zombies

Detection range for players wearing the corresponding head adjusted to be 37.5% of the normal range.

World generation

End ships

The middle iron block has been replaced with a hopper.
- Inside, there is a book written by Searge, which reads "We will have something else here soon..."

General

Non-player entities can no longer regenerate the obsidian platform when entering an end portal.
A non-player entity going through a nether portal no longer causes a return portal to generate on the other side if none exists already.

Added the powered byte tag to Music tile entity for note blocks.

Changes

Blocks

New textures that now vary depending on what direction they are placed from, similar to dispensers and pistons.
- It consists of a front, a back and a side texture (looks like arrows), so the orientation can be easily determined.
- The texture is animated - the colored "buttons" in the middle change color.
- The middle panel texture has a black outline.
3 modes: impulse, chain, and repeat - color changes based on mode.
- Impulse mode (orange): Command is run once on rising edge.
  - Same behavior and color as previous versions.
- Chain mode (green): Command is run whenever another command block pointing into it executes, and the command block in question is powered.
  - The chain signal is forwarded until the blocks get out of loaded chunks.
  - The signal is independent of the powered state of any block in the chain, as well as the command (or lack thereof) inside.
- Repeat mode (blue): Command is run every game tick while powered.
  - Like a minecart with command block but faster.
- Each new mode has its own block id and is obtainable with /give and pick block.
Power received is now a data tag, allowing command blocks to have such a state under control, independent of any nearby redstone signal.
Command block contraptions from earlier versions still work.
The "Done" button is now always available to press, even when the command line is empty.

Note blocks

Their power state is controlled through a tag, and can, therefore, be controlled independently on any redstone signal.

Items

  - Fills in 0.25s for non-weapons, 0.8s for swords, pickaxes, and shovels, and 1.2s for axes.
  - The meter can be displayed next to the hotbar (left or right based on the player's main hand), under the crosshair or turned off.
    - Looks like the icon for the Strength effect on the side of the hotbar, or like a dagger under the crosshair.
    - This is controlled in video settings.
Delay when selecting a sword, pickaxe, axe or shovel into the main hand.

15w38a

15w38a is the twenty-fourth snapshot for Java Edition 1.9, released on September 16, 2015,^[32] which adds skeleton horsemen.

Additions

Mobs

Skeleton horsemen

Added "skeleton trap" horses. When a player approaches to within 10 blocks, the following happens:
- The SkeletonTrap flag is cleared.
- Lightning strikes the horse.
- The horse becomes skeletal if it isn't already.
- The horse becomes tamed.
- The horse becomes fully grown (if a baby) and the breeding cooldown is reset.
- A skeleton is spawned riding the horse.
  - If on Peaceful, the skeleton doesn't spawn, while the horse does.
  - The skeleton has damage immunity for 3 seconds.
  - The skeleton doesn't despawn, since it has the tag PersistenceRequired set to true.
  - The skeleton is wearing an iron helmet, unless it randomly spawned with some other headgear.
  - The skeleton's bow and helmet are enchanted as if on an enchantment table at level 5–22.
    - The level is higher depending on regional difficulty; on Easy it is always a level-5 enchantment.
- Three additional skeletal horses with riders are spawned in the vicinity.

Command format

SkeletonTrap (byte): Indicates whether the horse is a skeleton trap (i.e. whether or not the horse will spawn 4 undead horsemen in its place when a player gets within 10 blocks of it).
- /summon EntityHorse ~ ~1 ~10 {SkeletonTrap:1b}.
SkeletonTrapTime (integer), incremented each tick when SkeletonTrap is set to 1. The mob automatically de-spawns when it reaches 18000 (15 minutes). This will prevent the hostile horses from overflowing the world, similar to chicken jockeys.
- /summon EntityHorse ~ ~1 ~10 {SkeletonTrap:1b,SkeletonTrapTime:17980}.

Added "Times Slept in a Bed" (stat.sleepInBed) to track the amount of times a player has used a bed.

Changes

Blocks

All sloped rail types

Hitbox heights are decreased from 10 pixels of block to about 2.5 pixels of a block.

Crops

Improved drop chances for seeds (average 1 ⁵⁄₇ per crop harvested instead of 1 ³⁄₅), potatoes and carrots (average 2 ⁵⁄₇ per crop harvested instead of 2 ³⁄₅), and beetroot seeds (average 2 per crop harvested instead of ⁴⁄₅).

End rod

The player can no longer step up onto an end rod as if it was a slab.

Fire

Goes out less often under the rain.
- The chance of going out each fire tick is reduced from 100% to 0–45%, depending on the age property.

Mobs

General

Improvements to mob AI.

Skeletons

Have new idle sounds.
Skeletons can now walk, strafe and shoot at the same time.
- They walk away from players that are too close and towards players that are too far.
  - They also sprint towards the player when very far away.
Now can spawn riding "skeletal horses" through the new "skeleton trap" horse.

Tamed ocelots & wolves

Deaths (and killers) are now announced to their owners on chat, even if unnamed.

Villagers

Now pick up and plant beetroot seeds.
Now pick up beetroot and use it in the same way as they do carrots and potatoes.

Non-mob entities

Lightning

Natural lightning strikes may spawn a "skeleton trap" style skeletal horses.
- Chance is calculated from the regional difficulty score: 5% * raw regional difficulty score.
  - 3.75–7.5% chance on Easy, 7.5–20% chance on Normal, 11.25–33.75% chance on Hard.

Additions

Items

Elytra

They function according to hang glider aerodynamics.
- Players don't receive fall damage if they fall from a small height while flying slowly (not nose-diving).
- Players still receive fall damage if they nose-dive directly into the ground.
Have to be equipped in the "chestplate" slot in order to work.
Takes durability damage at a rate of 1/s.
Have 431 durability and can be repaired on an anvil using leather.
- When the durability reaches 1/432, elytra doesn't break or take damage. Instead, they stop working and the texture changes to broken-looking elytra.
Can be given the Unbreaking enchantment using an anvil or commands.
Legs make a "walking movement" animation when player is stalling in the air.
Found on end ships within an item frame, replacing the beacon/Searge's book.
They fold in when not in use.
Capes don't display while wearing.

Command format

All entities
- Passengers (list): Replaces the original Riding compound tag. It has the ability to specify multiple passengers at equal depths, unlike Riding. Instead of the deepest-nested Riding entity being the bottom-most in the stack of riding entities, the entity at the root of the data is at the bottom of the stack. For example, the armor stand in the following command is at the bottom of the stack while the cow and pig are at the same depth:
  - /summon ArmorStand ~ ~1 ~ {Passengers:[{id:"Cow"},{id:"Pig"}]}.
- Riding (compound): The Riding tag has been removed in favor of the new Passengers tag.
Players
- RootVehicle
  - With the introduction of the Passengers tag, this new compound holds a copy of the entity the player is currently riding. AttachLeast and AttachMost are the UUIDLeast and UUIDMost of that entity, while Entity holds the actual data.
  - /testfor @a {RootVehicle:{AttachLeast:1l,AttachMost:1l,Entity:{id:"Boat",CustomName:"Test"}}}.
Boats
- Type (string): Determines the wood material of the boat that is displayed. Values are: oak, spruce, birch, jungle, acacia, dark_oak.
  - e.g. /summon Boat ~ ~1 ~ {Type:"acacia"}.

Changes

Non-mob entities

Boats

Now are larger, somewhat slower (until 15w42a), and have oars which the player rows.
Six different kinds of wood boats are available, corresponding to the types of wood.
- Only oak boats may be crafted, due to MC-89942.
- The tag Type (string) have now added for the boat entity, taking values oak, spruce, birch, jungle, acacia and dark_oak.
Changed how player movement is sent and processed by the server, making boats much less susceptible to client/server position desync than they had been.
Boats are now much less fragile, no longer being destroyed by collisions while in the water, though they can still be destroyed by fall damage onto the ground.
Crafting recipe now includes a wooden shovel for the oars.
Now require oar movement to move, using the left and right keys – these controls were changed in a later snapshot, 16w04a.
- The left key paddles the left oar, turning the boat to the right – and vice-versa.
- Holding both left and right paddles both oars, propelling the player forward. Rapidly pressing left and right in alternation makes the boat travel even faster.
- Using the mouse, the player can look fully to the left or to the right, but not behind. This does not turn the boat.
- Holding the forward, back or sprint keys no longer have any effect.
The player cannot use or attack with items in hand while the boat is in motion. This was changed in 15w42a.
All entities can go into boats, with a maximum of two entities (including the player).
Mobs can no longer control boats.

World generation

End ships

Removed hopper with book.
Removed iron blocks.
Extended the obsidian pattern on the floor.
Added an item frame containing elytra.

Gameplay

Trading

Clerics now sell ender pearls (for 4–7 emeralds) instead of eyes of ender.
- This means it is no longer possible to travel to the End without visiting the Nether.

General

Capes

Mojang Cape texture modified. Also, the capes are no longer displayed if the player is wearing elytra.

Multiplayer

Improved cheat detection.

Additions

Blocks

Frosted ice

Created when using "Frost Walker" enchantment.
Cannot be obtained in inventory, neither with Silk Touch, pick block nor with commands. (Can only be placed using /setblock, /fill etc.)
Despawns after a few seconds.
- Despawning takes place in four breaking stages (blockstates: age:0, age:1, age:2, age:3). Still decays with randomTickSpeed set to 0, but a higher number makes it decay faster.
- Despawns faster with a higher light level (doesn't despawn at night).

Command format

Brewing stands
- Fuel (byte): Stores how much fuel is remaining in a brewing stand.
  - e.g. /setblock ~ ~1 ~ minecraft:brewing_stand 0 replace {Fuel:127b}.

Gameplay

"Treasure" enchantments.
- Can only be obtained from chest loot, fishing, or trading for enchanted books.
New treasure enchantment: Frost Walker.
- Turns water into frosted ice.
- Different tiers:
  - Level I creates a circle of frosted ice around the player with a radius of 2 blocks.
  - Each additional level adds 1 to that radius.
- Works while riding mobs.
- Doesn't turn water into frosted ice if an entity is in that spot.
- Works as long as the player is within one block above a solid block.
- Flowing water also turns into frosted ice, making one bucket of water enough to make an infinite water source.
- Cannot be combined with Depth Strider enchantment.
New treasure enchantment: Mending.
- Any experience collected while holding the item repairs it instead of going to the experience bar.
  - Mainhand, offhand, and armor slots all count as held.
  - If multiple held items have the enchantment, one is chosen at random for each XP orb collected.
  - Repairs at a rate of 2 durability per XP.
  - If the amount of repair needed is less than the value of the XP orb, the extra XP goes to the experience bar.
  - Shields cannot be enchanted with Mending using /enchant or an anvil in Survival.
    - Mending enchantment does affect the shield when using anvil in Creative or NBT commands.

General

Splashes

Added the following splashes:
- "Falling with style!"
- "There's no stopping the Trollmaso"
- "Throw yourself at the ground and miss"

Changes

Blocks

Brewing stand

Requires blaze powder to be able to use.
- One piece of blaze powder allows for 30 ingredients to be brewed in the brewing stand (tag: Fuel:30b).
  - To be exact, it removes 1 from fuel (1 blaze powder = 30 fuel) every time the player puts an ingredient in (if the player takes it out and puts it back in, it takes another fuel).
- Can be automated by putting a hopper feeding in the side of the block like water bottles.

Items

Elytra

Nerfed - the player is no longer able to go higher than where they started.
New sneaking animation.
The player can now fit through one block high gaps while gliding.
Horizontal collisions now deal damage, new death message: "Player experienced kinetic energy".

Non-mob entities

Boats

Now slightly faster than sprinting.
- This makes them similar in speed to the old boats, though with less momentum.
Players can now use items and attack immediately after they stop rowing.
All types of boats are now craftable, except for dark oak boats.^[42]

Gameplay

Anvil repairing

Renaming an item does not increase the repair cost for a future repair/rename any more.

Enchantments with maximum level I no longer display the level, e.g. "Infinity" rather than "Infinity I".
When multiple pieces of Thorns armor are worn, one is now chosen at random instead of always using the "bottommost" piece.

General

Players

When crouching, players are 1.65 blocks tall (versus 1.8 blocks normally).
When flying with elytra, players are now only 0.6 blocks tall.
When laying in bed, players are as tall as a 0.2 blocks cube.

Splashes

Changed "0% sugar" to "1% sugar".
Removed "SOPA means LOSER in Swedish!".

Additions

World generation

Igloo

Spawns randomly in ice plains and cold taiga (but not the hills variant).
- Spawning parameters are shared with desert pyramids, jungle temples, and witch huts: the fact of a structure spawn is decided, then the biome determines which structure (if any) is spawned.
Created by Searge (as found in the NBT data).
An igloo contains: 9 white carpets, 3 light gray carpets, 2 blocks of ice, a redstone torch, a furnace, bed and a crafting table.
Some igloos have a stone brick basement, with a cauldron, 2 red carpets, a brewing stand, 3 spruce stairs, 2 torches and a loot chest, along with a villager priest and zombie villager priest behind iron bars. An oak trapdoor with ladders leads down into the basement. Cracked and mossy stone bricks can also generate.
- In the loot chest, there is sometimes be a golden apple in the central spot, hinting that the player needs to cure the zombie.
- Always spawns with a splash potion of Weakness, hinting the player to use these on the zombie villager to turn it into the same type of villager next to it.
- The zombie has the PersistenceRequired tag which makes it not despawn.
- Silverfish spawn in some stone brick blocks.

Command format

Chests/minecart chests
- [String] LootTable: Loot table to be used to fill the chest when it is next opened or destroyed. When the chest is part of a double chest, only the half corresponding to the tagged single-chest is affected.
  - e.g. /setblock ~ ~1 ~ minecraft:chest 0 replace {LootTable:"minecraft:chests/simple_dungeon"}.
- [Long] LootTableSeed: Seed for generating the loot table. Used in vanilla survival to replicate chest content in new worlds with same seeds. 0 or omitted uses a random seed.
  - /setblock x y z minecraft:chest 0 replace {LootTable:"chests/simple_dungeon",LootTableSeed:12345}.
All mobs
- [String] DeathLootTable (string): Determines which loot table is used when the mob is killed.
  - e.g. /summon Creeper ~ ~1 ~ {DeathLootTable:"minecraft:chests/simple_dungeon"}.
- [Long] DeathLootTableSeed (long): The deterministic seed for grabbing data from the loot table. Used in vanilla survival to replicate chest content in new worlds with same seeds. Must not be 0.
  - e.g. /summon Creeper ~ ~1 ~ {DeathLootTable:"minecraft:chests/simple_dungeon",DeathLootTableSeed:123l}.

General

Language

Added LOLCAT.
Replaced Australian English (Australia) with English (Australia). (Australian English had many jokes/slang, but English (Australia) is a real language.)

All loot from mobs, chests etc. is now based on loot tables, excluding block drops.
- Can be changed by mapmakers by adding a json file within the "WORLD/data/loot_tables" folder, however, it is broken in 43a.

Changes

General

Mobs wearing armor or carrying weapons no longer drop the equipment, i.e. HandDropChances and ArmorDropChances are ignored.
- See MC-91147.

Cave spiders & spiders

Drop eyes more often (now 50% chance, previously a 33% chance normally and 66%/77%/82.5% with Looting) and the amount is now increased by Looting.

Chickens

Now drop more than one meat item when killed with Looting.
- See MC-91074.

Elder guardians

No longer rarely drop fish as if from fishing.
- See MC-91152.

Drop chances for raw fish and prismarine crystals changed. Now it is a 40% chance for fish, 40% for crystals, and 20% of nothing, with the amount increased by Looting. Formerly it was 33% raw fish and 33% of crystals only if the raw fish drop failed, with Looting increasing the chances but not the amount.

Endermen

No longer drop the held block.
- See MC-91151.

Ghasts

Now drop 0–3 gunpowder and 0–2 ghast tears (up from 0–2 gunpowder and 0–1 tears), incremented as usual with Looting.

Guardians

No longer rarely drop fish as if from fishing.
Drop chances for raw fish and prismarine crystals changed. Now it is a 40% chance for fish, 40% for crystals, and 20% of nothing, with the amount increased by Looting. Formerly it was 33% raw fish and 33% of crystals only if the raw fish drop failed, with Looting increasing the chances but not the amount.

Gameplay

Fishing

The Lure enchantment no longer affects the chances of catching things, only the delay.
The Luck of the Sea enchantment is broken due to a typo in the new fishing loot table.
Fished junk is less damaged (0%–90% durability remaining) while treasure is more damaged (0%–25% durability remaining).
Ink sacs now are caught singly with weight 10 (formerly a stack of 10 with weight 1).

General

The format is updated, so that rather than a 'items' node containing 'item' entries, it is an 'entries' node containing 'type' and 'name' entries.
- Type entries can be 'item', 'loot_table', or 'empty'.
- Name entries can either be item identifier for items, or the location and name of the loot table.
  - Example:

"type": "loot_table",

"name": "minecraft:gameplay/fishing/treasure",.

This allows for easier nested loot tables.

The fishing tables are now available, along with loot for skeleton horses, zombie horses, and sheep without wool.
Added the function 'set_damage', which is used to change the durability of a tool.
Fixed some loot tables.
- Guardians and elder guardians have their rare drop of fishing loot again, though it includes fishing junk and fishing treasure as well.
- Elder guardians only drop sponges when killed by the player.
- Horses drop 1 leather. Skeleton and zombie horses drop 1 bone and 1 rotten flesh, respectively.
- Squid reverted back to dropping 1–3 ink sacs (was changed to 0–2 in 15w43b).
- Wither skeleton coal drop chance reverted back to earlier behavior: drops −1–1 (i.e. a 66% chance of 0 and a 33% chance of 1) with the amount increased as usual by Looting.
- Spider and cave spider eye drop chance adjusted, now drops −1–1 (i.e. a 66% chance of 0 and a 33% chance of 1) with the amount increased as usual by Looting.

- Can no longer be zoomed in.
This reverts maps to 1.8 behavior.

Command format

General

Tab-completed coordinate arguments now become tildes if no block is in focus.

15w46a

15w46a is the fortieth snapshot for Java Edition 1.9, released on November 12, 2015.^[53]

Changes

Blocks

Banners & signs

Now replace replaceable blocks such as grass, instead of trying (and failing) to be placed on them.

Farmland

Mobs smaller than 0.512 cubic blocks can no longer turn farmland to dirt by jumping or falling on it.
- This includes rabbits, chickens, bats, ocelots, wolves, cave spiders, endermites, silverfish, small slimes, small magma cubes, and all current baby mobs.

Iron bars

Their sides now include an edge texture.

Rails

Powered rails and activator rails now transmit power to each other.

Redstone

Hitbox for redstone is now smaller based on the connections, similarly to fences.

Redstone blocks

Now emit power through adjacent blocks.
- Reverted in 15w47a.

Items

Filled buckets

Now replace single snow layers when used on the top, instead of placing the water or lava in the air above the snow layer.

Mobs

General

Mobs can no longer spawn inside blocks that block movement but are transparent, such as leaves.
Also, mobs can no longer spawn in blocks containing any type of rails, buttons, tripwire hooks, pressure plates, levers, redstone torches, redstone repeaters, comparators, or redstone dust.
Something about rendering has changed; screenshots taken with the exact same position, viewing angle, FOV, etc. as an equivalent screenshot in 15w45a or earlier will differ.

Iron golems

If spawned in 15w46a and later, they have 100% knockback resistance.

Rabbits

Smaller than before.
Chance to drop a rabbit's foot is now 10% + 3 percentage points per level of Looting (was 2.5% + 1 percentage point per Looting).
Now only spawn in deserts, flower forests, taiga, mega taiga, cold taiga, ice plains, ice mountains, ice plains spikes, and "hills" and "M" variants of these biomes. Even in these biomes, spawn chance is somewhat reduced (weight 4 out of 44–52 rather than 10 out of 50–58).
Are faster when panicking.
No longer prefer begging for food to mating.
Non-killer rabbits now avoid players within 8 blocks and most hostile mobs within 4 blocks (except slimes, magma cubes, and ghasts), and move faster when doing so. Also, avoidance range for wolves was reduced from 16 to 10 blocks.
Health reduced from 10HP to 3HP.
Naturally-spawned rabbit's skin depends on the biome. When breeding rabbits, there is a 5% chance the baby matches the biome rather than either parent.
- In a snowy biome, 80% white and 20% black & white.
- In a desert or desert hills, 100% gold.
- Otherwise, 50% brown, 40% salt & pepper, 10% black.
MoreCarrotTicks no longer has any effect.
- When destroying crops, MoreCarrotTicks is set to 40 rather than 100.
Rabbits eating carrot crops now reduces the growth stage by 1 level, only removing the crop block entirely if the growth stage was 0.

Snow golems

No longer leave a trail of snow if the game rule mobGriefing is false.

Wolves

Collar, when tamed, is now red, as it had been in releases before 1.8, rather than orange.

World generation

Ocean monuments

Now require a 16 block square radius of deep ocean, not just a single deep ocean block at the center.

Gameplay

Experience

Now is collected at the middle rather than at the head.
- This means that if a large amount of experience is collected, it no longer blocks the player's view.
Blocks no longer drop XP when the doTileDrops gamerule is false.

Fixes

47 issues fixed

- Among other things, this means mobs can now spawn on them.

Arrows that bounce off a target (e.g. a shield or a sitting dragon) and may be retrieved become dropped items if near zero momentum after being bounced.

Bottles o' enchanting, eggs, ender pearls, snowballs, thrown potions

No longer collide with non-opaque blocks.
- Even non-opaque blocks that are solid, such as glass (see MC-93636).

/particle

Now has an optional player parameter to specify which players can see the particle when inside the range. When left out, everyone in range can see the particles.

1.9-pre2

1.9-pre2^[74] is the second pre-release for Java Edition 1.9.

Changes

Gameplay

Mob spawning

Pack spawning is less likely to spawn the full pack, and less likely to spread them out.
- Previously, spawning a pack would start from the center three times and cumulatively adjust the coordinates four times by up to ±5 in X and Z, trying to spawn a mob each time, for a total of twelve spawn attempts (although it stops early if a full pack has spawned). Now that "four times" is a random number 1–4, meaning fewer total spawn attempts and less chance for the attempt coordinates to get far from the pack center.
