Gameplay

 * Achievements
 * New achievement Overpowered.
 * Obtained by crafting an enchanted golden apple.
 * Requires first obtaining Getting an Upgrade.
 * Enchantments
 * New enchantment Depth Strider.
 * Allows the player to move faster while in water.
 * Can only be applied to boots in survival up to level III.
 * Spectator game mode
 * It can only be accessed and reversed via, either using ,  , or.
 * It is the default gamemode on the debug world type.
 * Like in creative mode, only the Void and can damage/kill a spectator.
 * Their player model in the inventory is completely invisible.
 * Free roaming:
 * The world border has no effect on spectators (apart from the warning colors displaying).
 * They still can't exit the world boundary.
 * The player can fly through solid blocks (noclip).
 * If the head of the player is inside of a block, then an x-ray like effect will happen, where every block is invisible until it is adjacent to an intermidiate air block, or the model does not occupy a full block.
 * The mouse scroll wheel, the sprint key, the slowness and swiftness effects, all affect the flying speed.
 * Night vision effects still affect spectators.
 * First-person view through another player or mob’s eyes.
 * Includes non-mob entities like paintings or minecarts
 * Creepers, spiders and endermen apply a specific shader while spectating through each of them.
 * Spectating through a player shows the respective HUD.
 * Pressing the dismount key (shift by default), returns the player to flying mode.
 * Viewing privileges:
 * Cannot catch on fire, so their view isn't obstructed.
 * Spectators can see other spectators as disembodied translucent heads, with the corresponding player skin.
 * All invisible players/mobs appear visible, but translucent.
 * An optional held hotkey shows bright outlines on all players.
 * Can be color-coded to teams.
 * Spectators can look at the inventories of blocks like chests and entities like minecarts with chest.
 * This includes their own inventory.
 * Automatic targeted teleportation-spectators have a UI to teleport to other players.
 * The UI can only be brought up and interacted with, with the number keys or middle mouse click.
 * But the scroll wheel can still scroll through the different options.
 * It is similar to the regular hotbar in creative (it displays on the HUD), but contains special icons that appear to be different items, like barrier blocks or old player heads.
 * If there is at least 1 team set up, the UI distinguishes between teleporting to an individual or teleporting to a member of a specific team.
 * Otherwise it defaults to an all-inclusive, alphabetical list of players (except for fake players).
 * Team members are still sorted the same way, inside their own lists.
 * Both the player and the team icons are color-coded with respect to the team color.
 * The player icons that teleport are rendered with the skin of the head of the player, and resemble the way the player heads were displayed before 1.8.
 * If there are more than 8 players or 7 teams available to teleport, slots 1 and 8 will display right and left arrows respectively, to scroll through.
 * The arrows look very similar as the ones used in the resource pack menu and the server list.
 * The right and left arrow will not show up, if there are no more players to the right or left of the list respectively.
 * There is always an option in slot nine to close the menu.
 * Looks like a barrier block item.
 * Teleportation works across dimensions.
 * It is slightly more delayed on those cases, since it has to load the world first.
 * A spectator cannot:
 * Load terrain.
 * Interact with blocks or entities, apart from spectating through the latter.
 * Interact with any inventory (including their own).
 * Look at the inventory of other players/mobs, apart from the hotbar items of players.
 * Control the behavior of any entity they spectate through.

Command format

 * Target selectors
 * Targets all entities including players.
 * Can specify the type of entity by entity ID, to either include or exclude with, to only apply it to chickens or  , to apply it to every entity that isn't a skeleton.
 * Example:
 * Kills every chicken within a radius of 50 blocks.
 * Any entity within a radius of 5 blocks will be teleported 5 blocks upward.
 * Commands
 * Removed "Ouch! That looked like it hurt" message.
 * Allows commands to be run from the position of specified entities.
 * A  argument allows the  command, to run only if a block is detected at a specific location relative to the target.
 * Syntax:
 * {{cmd|execute    detect     criteria (referred to as "triggers"), and can only modify the score of the player running the command.
 * Allows non-op players to use s as well as to prevent its abuse.
 * Can be used by non-operator players.
 * For a player to run this command, the trigger must be enabled for that player.
 * {{cmd|scoreboard players enable }} will enable the specified player to use the specified trigger objective.
 * Trigger availability is stored per player.
 * One trigger may be disabled for a player, but that player can use a different trigger.
 * One player may be unable to use a trigger, but another player can use the same trigger.
 * Disabled after the trigger has been used (must be re-enabled to use the trigger again).
 * Mostly for use with {{cmd|tellraw}}.
 * Syntax: {{cmd|trigger  }}.
 * {{cmd|replaceitem| ...}}

 * will move the selection from the first location to the second location, which may overlap.
 * will force the cloning operation, even if the areas overlap.
 * only needs to be specified if using.
 * Syntax: {{cmd|clone      <z2> <x> <y> <z> [mode]}}.
 * Example: {{cmd|clone 1001 3 1002 1011 3 992 1001 5 992 masked}} Targets the cuboid volume defined by the opposite corners: [1001,3,1002],[1011,3,992] and clones it such that the old corner coincides with the destination (and orientation) at [1001,5,992].
 * {{cmd|fill}}
 * Fills a given volume with a specified block.
 * It cannot replace or fill block entities with specific data tags.
 * Up to 32768 blocks can be filled.
 * Syntax: {{cmd|fill <x1> <y1> <z1> <x2> <y2> <z2> <TileName> [dataValue] [oldBlockHandling] [dataTag]}}.
 * The  parameter determines the fate of the blocks, occupying the volume about to be filled,
 * It takes the same values here as it does in {{cmd|setblock}}:,   and   – as well as two additional values:
 * to only fill the outer layer of blocks, and fill the inner part with air,
 * to fill the outer layer of blocks, and keep the inner part the same.
 * Example: {{cmd|fill 1001 3 1002 1011 5 992 wool 6 replace}} Fills the given area with pink wool.

 * {{cmd|testforblocks}}
 * Compares two areas of a world, to check if they share the same blocks on the same configuration (including orientation).
 * The mode can be set to  or
 * is the default, while  will ignore air blocks.
 * Syntax: {{cmd|testforblocks <x1> <y1> <z1> <x2> <y2> <z2> [mode]}}.

 * Syntax:
 * {{cmd|stats entity }}
 * {{cmd|stats block [x] [y] [z] }}
 * Alternative and more useful way of interacting with the  tag.
 * After the  there are currently 5 possible stats that can be updated: ,  ,  ,   and.
 * Example: {{cmd|stats entity @a set AffectedBlocks @a Test}} Updates a scoreboard objective named 'Test' for all players whenever a command is performed relative to them. The objective will update by the number of blocks affected by the command. Since the stat was set to, this means that if the command is {{cmd|fill}}, it will update the objective for whoever is running the command (@a) by the number of blocks filled.
 * {{cmd|worldborder}}
 * {{cmd|worldborder <set,add,center,damage,warning,get>}}
 * {{cmd|worldborder set <sizeInBlocks> <timeInSeconds>}}
 * The first argument sets the size of the border (both the width and depth) in blocks, and the second sets the speed of the border when it expands or shrinks.
 * The shape of the border can only be a square.
 * {{cmd|worldborder add <sizeInBlocks> <timeInSeconds>}}
 * Adds blocks to the current size of the world border. It can use negative numbers to subtract to the size of the border.
 * {{cmd|worldborder center <x> <z>}}

 * Syntax: {{cmd|particle <x> <y> <z> <xd> <yd> <zd> [count] [force]}}.
 * Example: {{cmd|1=particle lava ~ ~1 ~ 1 1 1 0.5 50 normal @e[type=Chicken]}} Creates 50 lava popping particles, centered one block above the block/entity running the command, spreading around a radius of 1 block, with a speed of 0.5, relative to all chickens in that world.
 * The  argument can be set to   to display particles, even if a player has his 'Particles' toggle set to Minimal or Decreased.
 * List of particles:,  ,  ,  ,  ,  ,  ,  ,  ,  ,  ,  ,  ,  ,  ,  ,  ,  ,  ,  ,  ,  ,  ,  ,  ,  ,  ,  ,  ,  ,  ,  ,  ,  ,  ,  ,  ,  ,  ,  ,  ,.
 * Gamerules
 * Prevents command block output from being stored in chat logs. In multiplayer it also prevents player-initiated commands from being stored. Unrelated to commandBlockOutput, which is output into the visible chat.
 * If set to false, player-run commands will not show a message.
 * Prevents death messages like "[player] fell out the world" from appearing in the chat.
 * This enable/disable reduced information on the F3 debug screen, like in video settings.
 * Set to 1, overrides the 'reduced debug info' setting in clients.
 * Controls how often a random tick occurs
 * Random ticks influence the next things: pigmen spawning from portals, all plant growth, leaf decay, fire spread, ice melting, grass/mycelium spread and farmland hydration.
 * If set to 0, random ticks never occur.
 * The ability to create custom gamerule variables.
 * These are fake gamerules which don't affect gameplay by themselves, but can be used with {{cmd|stats}} with the new  argument, to update a scoreboard objective based on the value of that gamerule.
 * Declare using: {{cmd|gamerule <newRuleName> }}.
 * Access using: {{cmd|gamerule <newRuleName>}}.
 * Scoreboard
 * New objective criteria for team-specific kills, e.g.:.
 * New objective criteria.
 * Acts like the  criteria.
 * Can be interacted with using the {{cmd|trigger}} command.
 * Mostly for use with {{cmd|tellraw}}.
 * The ability to iterate over every scoreboard player with.
 * This will also affect players who are offline.
 * Fake players can be created when run in a command block.
 * They only exist through the distinct scoreboard operations and functions, and are merely virtual within the context of the gameplay.
 * They do not bring the player count up on servers and do not appear on any player listing.
 * Fake players with a name starting with, will never show up on the scoreboard sidebar.
 * New {{cmd|scoreboard}} subcommands: {{cmd|scoreboard reset}}, {{cmd|scoreboard operation}}, {{cmd|scoreboard test}} and {{cmd|scoreboard enable}}.
 * The  subcommand can reset all objectives for a player or reset a player's objectives one by one.
 * Example: {{cmd|scoreboard players reset @a anObjective}} Resets the scores of an objective named anObjective for all players in the world.
 * The  subcommand can apply arithmetic operation to and between scores (+ – * / % < > =) and therefore accumulate player scores.
 * Example: {{cmd|1=scoreboard players operation #teamscores redScore += @a[team=red] blueKills}} Adds every red player's count of kills on blue to the red team's score of kills.
 * Can be tested with a comparator to see if two scores are greater than, smaller than or equal to each other.
 * The  subcommand can be used to test, if a scoreboard value is between a min and a max value.
 * Example: {{cmd|scoreboard players test #global anObjective 12 19}} Checks whether the global score of the given objective is between 12 and 19, inclusive.
 * The  subcommand can be used to enable a   objective.
 * Example: {{cmd|scoreboard players enable Trigger_a}} Enables a  named Trigger_a.
 * Different teams can have multiple objectives displayed in the sidebar.
 * Example: {{cmd|scoreboard|objectives setdisplay sidebar.team.yellow anotherObjective}} This refers to the team color, not the team name.
 * Testing for scores also works in  entity selector.
 * Added scoreboard team property to disable name tag visibility: {{cmd|scoreboard teams option nametagVisibility}} with options,  ,   and   (default).
 * Added scoreboard team property to disable death messages: {{cmd|scoreboard|teams option deathMessageVisibility}} with the options:,  ,   and   (default).
 * Command {{cmd|scoreboard|players}} can now filter by NBT data.
 * NBT Tags
 * Block entities item form can hold custom NBT tags that are merged to the specified block entity when they're placed.
 * Example: {{cmd|give @p command_block 1 0 {BlockEntityTag:{Command:"{{cmd|setblock ~ ~ ~ minecraft:diamond_block}}" }} }} Gives a command block that, when placed, will automatically have the command {{cmd|setblock ~ ~ ~ minecraft:diamond_block}} set.
 * A way to prevent containers from being opened by players outside of creative.
 * Locked containers can only be opened by clicking while holding any item renamed to the given string (like a password).
 * The item is not removed on use.
 * Containers can be unlocked by clearing the string from the tag.
 * Mostly for use in adventure mode.
 * Items with this tag display the names of the blocks that they can destroy in the item tooltip.
 * Example: {{cmd|give @p minecraft:diamond_shovel 1 0 {CanDestroy:["minecraft:sand","minecraft:grass"]} }} Gives a diamond shovel that can only break grass and sand.
 * If an invalid item name is put in, it will display as "missingno" under the "Can Break" list.
 * Allows placing of certain blocks against other blocks in adventure mode.
 * Example: {{cmd|give @p minecraft:stone 16 0 {CanPlaceOn:["minecraft:diamond_block"]} }} Gives a block of stone that can only be placed on diamond blocks.
 * If an invalid item name is put in, it will display as "missingno" under the "Can Be Placed On" list.
 * The number of ticks before an item entity can be picked up.
 * Set to 32767 for items that can't be picked up.
 * Defines whether a written book is an Original a Copy of Original or a Copy of a Copy.
 * Allows hiding of certain parts of the tooltip.
 * Bit field determining which parts of the tooltip to hide on an item. 1 for, 2 for  , 4 for  , 8 for  , 16 for   and 32 for various other information (including potion effects,  , written book   and  ,   and  ).
 * Examples: Setting the bit field to 3 would hide both  and   tags, and setting it to 63 would hide every tag.
 * Contains the item data of the item currently held in the player's hand.
 * Added to compact the process of testing if a player is holding a specific item.
 * Previous method required nine commands (one per slot in the hotbar); now requires only one command.
 * Entities without AI will not attack players, move or rotate on their own, and do not despawn.
 * They also do not respond to gravity or collision with other mobs, but can still take damage, die, be caught on fire, and ride other entities.
 * Setting to 1 disables an entity's AI.
 * Controls villagers giving xp for trading.
 * Set to 1 for xp or 0 for no xp.
 * Option to show or hide all particles for a potion effect, as opposed to the  tag, which only show fewer particles.
 * Set to 1 to show, 0 to hide.
 * Determines whether sound is produced by an entity, such as idle and hurt sounds.
 * Setting to 1 disables sound effects.
 * Allows a command block or sign to increase a certain score in the scoreboard when it runs successfully.
 * The command will increase the score based on the number of items/blocks/entities/successes.
 * For example, a command block with this tag running a command which affects items (e.g. ) will cause it to update the score based on the number of items given.
 * Syntax:.

 * There are 16 customization options which can be used to affect various aspects of Minecraft's terrain generator. These can be changed by moving sliders or by typing in values directly.
 * Main Noise Scale X/Y/Z to smooth out terrain, larger values for smoother terrain; Biome scale/depth weight and Biome scale/depth offset to stretch/squash terrain vertically based on the biomes default height settings; Upper/lower limit scale to make terrain more solid/riddled with holes, depending on how close the values are to each other; Height Stretch to pull terrain upward, with smaller values causing more extreme stretching; Height scale, Coordinate scale, Depth base size, Depth noise exponent and Depth noise scale.
 * There are seven presets.
 * Water World, Isle Land, Caver's Delight, Mountain Madness, Drought, Caves of Chaos and Good Luck.
 * Each page has a button to randomize the various values and a button to reset to default values.
 * Uses the 'generator-settings' string known from superflat presets for server.properties and world data.
 * Generate structures button disappears when selected.
 * Debug mode world type
 * Useful for resource pack makers.
 * Hold and cycle through "World Type" option to select it.
 * Other world options are not available.

 * Andesite
 * Crafting recipe: 1 cobblestone and 1 diorite.
 * Granite
 * Crafting recipe: 1 Nether quartz and 1 diorite.
 * Coarse dirt
 * Replaces the grassless dirt variant found in mega taiga, mesa and savanna biomes.
 * All worlds with grassless dirt blocks will seamlessly change over to coarse dirt, as it uses the same block ID and data value as the original grassless dirt block.
 * Slightly darker texture than regular dirt.
 * Silk touch is not required for obtaining it in survival.
 * Tilling coarse dirt with a hoe will turn it to regular dirt.
 * Crafting recipe: dirt and gravel in a 2×2 checkered pattern yields four coarse dirt.
 * Prismarine
 * Generates in ocean monuments.
 * Can be crafted with prismarine shards.
 * The cracks in prismarine appear to slowly change color between brown, blue, gray and purple.
 * Prismarine bricks
 * Generate in ocean monuments.
 * Can be crafted with prismarine shards.
 * Dark prismarine
 * Generate in ocean monuments.
 * Can be crafted with prismarine shards and an ink sac.

 * Can be crafted into chiseled, smooth, stair and slab forms.
 * Chiseled variant has a wither pattern to complement the creeper pattern found in chiseled sandstone.
 * Slabs have a smooth variant, similar to stone and sandstone.
 * Comes as a smooth double slab –.
 * Generated only in Mesa biomes at cave entrances.
 * Iron trapdoor
 * Can only be opened and closed using redstone, similar to an iron door.

 * Can be crafted back into 9 slime balls.
 * Players and mobs that land on their top side will bounce, like on a trampoline.
 * This negates all fall damage.
 * Holding will negate the rebound, while still negating the fall damage.
 * Bounce rebound velocity is scaled by impact velocity.
 * Height can reach up to 60% of initial height, which implies a great restitution coefficient.
 * Does not affect falling item entities.
 * Walking on it is slower than walking on soul sand and close to one's speed while sneaking.
 * The placing/breaking sounds use the hurt sounds of slimes.
 * Can be mined with only one click, without any tools in survival.
 * Slime blocks will push and pull each other, along with adjacent blocks, when at least one of them is moved by a sticky piston.
 * Normal pistons will have the same effect, except that they fail to pull even a single slime block.
 * Coded by KaboPC and Panda4994. Follow all the existing rules that pistons followed:
 * A chain of slime blocks and its adjacent blocks connected to a piston, in any arrangement, can be moved as long as the following conditions are met:
 * The piston is not moving more than twelve blocks at a time.
 * Non-movable blocks are not obstructing the path.
 * Not a single slime block in the chain is attached to the piston itself.
 * Allows for moveable contraptions.

Mobs

 * All mobs
 * Updated to the new AI.
 * Now show a glow of a slightly different color when hurt.
 * Armor
 * Worn armor no longer gets colored when the respective mobs/players are hurt.
 * Villagers
 * Now have a system for distinguishing professions (colored clothes) and careers.

 * When a baby villager is born, both parents lose their willingness.
 * Villagers become willing to breed by consuming food: 3 bread or 12 potatoes or 12 carrots.
 * Finding out a villager's willingness in survival is achieved by counting the amount of xp given when trading:
 * Normal trading yields 3–6 experience points.
 * Trading that makes the villager willing yields 8–11 experience points.
 * Changes to the farmer (profession) villager AI:
 * Harvest, collect and replant grown potato, carrot & wheat crops.
 * Craft wheat into bread.
 * Share food with fellow villagers.
 * Wither skeletons
 * Hitbox has been changed from 2.5 to 3 blocks.

 * Iron golems, snow golems & withers
 * Can be spawned by arranging the blocks, in equivalent rotations of the default on the horizontal plane.
 * This does not affect the orientation of the spawned mob.
 * Can be spawned using dispensers, which places the final block in the appropriate place.
 * This does not affect the orientation, either.
 * Zombies, zombie pigmen, skeletons, wither skeletons, other creepers & witches
 * Run away from creepers that are about to explode.

Non-mob entities

 * All items
 * The dropped item entities now face the player in all three axis on fast graphics.
 * Arrows
 * Behave differently underwater.
 * They will lose all velocity after a few blocks and slowly fall.
 * Fire arrows will be immediately extinguished.
 * Minecarts with TNT
 * Can be ignited with a flame enchanted bow.
 * Explosions no longer stack linearly.
 * Now they stack following a function with a horizontal asymptote
 * The domain is the amount of minecarts and the range is the explosion strength.
 * This puts a hard limit on the possible explosion strength.
 * Item frames
 * Can be seen from further away.
 * Items in item frames can now face eight different directions, instead of just four.
 * As long as the frame remains placed, it remembers the orientation of the last item it held and uses that orientation for the next item it holds.
 * Item frames can give off a signal detected by comparators, based on the direction the present item is facing.
 * Signal strength is as follows: 0: empty; 1: item; 2: item rotated once; 3: item rotated twice; ...; 8: item rotated 7 times.
 * The signal is independent of the specific item inside.
 * Paintings & item frames
 * Improved position handling of both.
 * Can no longer intersect with each other or one another on the same block face.

Removed

 * Humans leftover AI was removed making all the coding and features of the Human to the be removed, thus making the Mob completely removed.

Trivia

 * At the time, this was the longest development to a major update in the history of Minecraft, with the first snapshot coming out on January 9, 2014, 236 days before the full release.
 * The previous longest was 1.3.1, with 111 days from the first snapshot to the final release – less than half of 1.8's.
 * At the time, this update had the most development snapshots of any major update so far, at 52 snapshots.
 * The update with the most snapshots previous to this was also 1.3.1, with 19 snapshots, slightly more than one-third of 1.8's snapshot count.
 * 1.9 broke the record with slightly more snapshots, with 56.
 * Upon the release of 1.8, a change with how skins worked has caused skins that were changed after the release of 1.8 to not display on the player in versions 1.2.5 and prior.
