Polished andesite, polished diorite, polished granite

• Can be crafted with four of the respective raw stones in a 2×2 configuration.
• Polished forms have the same data value, blast resistance, mining time, and other properties as stone.

Slime block

• Crafted with 9 slimeballs, can also be crafted back into 9 slimeballs.
• Players, mobs and particles that land on their top side bounce, as if on a trampoline.
  • Bounce rebound velocity is scaled by impact velocity.
  • A bounce can be avoided by holding spacebar.
• Prevents fall damage.
• Walking on them is slower than walking on soul sand, about the speed of sneaking.

/blockdata

• Can amend and modify the NBT data of the block at specified coordinates.
  • Usage: /blockdata <x> <y> <z> <dataTag>

/difficulty

• Can be used to change the difficulty.

Target selectors

• Added @e.
• Can select entities.
• Can specify type of entity by entity ID to either include or exclude with [type=Chicken] or [type=!Skeleton].
  • Example: /kill @e[r=50,type=Chicken].

NBT format

• Added a tag that can lock containers.
  • Mostly useful for (adventure) maps in Adventure mode.
• Tag in JSON format: {Lock:Key}, containers can be unlocked by clearing their string for Lock (changing it to {Lock:}).
• The lock can be cleared with the command /blockdata.
• Locked containers can only be opened while holding an item renamed to the given string.
  • Example: If the value of the lock tag is "Key" ({Lock:Key}), a player is not able to open the chest unless they are holding an item named Key.
  • Item is not removed on use.
  • Only works if the item has a custom name (default names do not work).
    • Example: a chest with the tag {Lock:Diamond} cannot be opened when holding a diamond; the item held must be renamed Diamond.

Splashes

• Added "That's Numberwang!"

Mossy stone bricks

• Now can be crafted using 1 vine and 1 stone bricks.

Chiseled stone bricks

• Can now be crafted using 2 stone brick slabs on top of each other, similar to chiseled sandstone.

Anvils

• The cost of experience is now reduced.
  • Renaming items now only costs 1 level, repairing now starts out with 2 to 5 levels and tools can be repaired longer and with better enchantments, repairing costs can no longer be kept down by renaming items.

Furnaces

• When a furnace runs out of fuel, the smelting progress pauses instead of resetting.
  • Will be changed in a later snapshot.^[2]

Doors

• Can now stack to 64.
• Crafting recipe now gives 3 doors.

Baked potatoes

• Now restore 5 hunger points instead of 6.

Carrots

• Now restore 3 hunger points instead of 4.

Baby animals (sheep, pig, cow, chicken, cat, wolf, horse)

• All baby animal growth can now slowly be accelerated using the animal's breeding item.
• Baby animals make particles when right-clicked with the proper food.
  • It appears holding the right mouse button speeds up the growth-acceleration process.
• They randomly grow up instantly.

Villagers

• Now only breed when willing.
  • The first time a specific trade is done, the villager becomes willing, any other time there's a 1 in 5 chance the villager becomes willing.
• When a baby villager is born, both parents lose their willingness.
  • Finding out a villager's willingness in Survival is difficult: the only way to tell is the amount of XP they give when trading. Normal trading yields 3-6 experience points, trading and making a villager willing yields 8-11 experience points.

Boats

• Now break (into sticks and wooden planks) when landing on a solid surface after falling more than 3 blocks.

/clear

• Can be used to clear only a specific number of items and can be restricted to certain NBT data.
  • Example: /clear @p 383 120 34 {display:{Name:Michael}} removes up to 34 villager spawn eggs named Michael from player. Note: maximum removal item count does not work correctly (fixed in 14w02c).

/kill

• Now has a target selector argument.
• Can kill entities (including players) other than the player that ran the command.
• Can now be used by command blocks.

/testfor

• Can now also check for dataTags.
  • Example: /testfor @p {foodLevel:20}.
• No longer is exclusively usable in command blocks.

/tellraw

• A new tag called "insertion" allows text to be inserted into the chat that, when shift-clicked, inserts more text into the players' chat input.
  • Example: /tellraw @a {text:"CLICK",insertion:"This is a test"}.

Item IDs

• Changed from using numbers (for example, TNT's id was 46) to namespaced IDs of the form minecraft:item_name. (Example: minecraft:tnt)

Adventure mode

• Block interaction is now impossible by default.
• Block outlines do not show unless block can be interacted with.
• Added CanDestroy tag for tools.
• Items with this tag display the names of the blocks that they can destroy in the item tooltip.
  • Example: /give @p diamond_shovel 1 0 {CanDestroy:["sand","grass"]} to give a Diamond Shovel that can break grass and sand).

Enchanting

• Enchanting now costs 1 to 3 levels of experience and lapis lazuli, depending on the tier.
  • Player still needs the same minimum levels displayed on the enchantment table to enchant.
• The actual enchantment calculation is the same.
• One of the enchantments is displayed in the tooltip.
• The enchantments player would get do not change until they enchant it, or enchant something else.
  • This enchantment seed is stored per player.

Experience

• Leveling up now takes more experience.

Teleporting

• Relative teleporting is smoother and no longer brings players to a stop.
  • Preserves their velocity from before the teleport.

Trading

• Offers are less random and more useful.
• Existing villagers are not affected.
• Trading now gives experience.
• Villager profession is now displayed in trade GUI.
• Villagers start out with 2-4 trades unlocked.
• The disabled trade arrow now has a descriptive tooltip.
• Trades are now unlocked more freely (no longer requires trading last trade).
• There are now more villager professions (only notable trade changes and additions listed).

Chat

• Messages are now either chat, system or action bar messages.
• Action bar messages are always shown, chat and system messages are only shown if chat settings are configured that way.
• Some instances of usernames in the chat now show the player's UUID when hovered on when debug tooltips are enabled.

Debug screen

• Now shows which axis players are facing after the cardinal direction: "Towards positive/negative X/Z".

Difficulty

• Now saved per world.
• Defaults to Normal instead of Easy.
• Can be locked in a specific difficulty per world.
  • Locking cannot be undone without external tools.
  • The difficulty may still be changed when locked by using /difficulty.

Distance effects

• Ember particles emitted by lava no longer are generated at the wrong positions at high coordinates.
  • This bug would later return in Java Edition 18w10c.
• Suspension particles formed inside water no longer are generated at the wrong positions at high coordinates.
  • This bug would also later return in 18w10c.
• Water and lava dripping particles (formed from when such a fluid is above a block with air beneath) are no longer generated at the wrong positions.
• Piston arms no longer visually break down at high coordinates.
• Tripwire (including that which appears on tripwire hooks) no longer appears abnormally stretched at high coordinates.
• The inside faces of cauldrons, hoppers and flower pots no longer appear at the wrong positions or outside the block entirely at high coordinates.

3 issues fixed

From released versions before 1.8

• MC-1178 – Invalid biome ID in Superflat crashes Minecraft.
• MC-2367 – Players can place and remove arbitrary blocks in Adventure mode, breaking pre-1.4.2 maps.
• MC-11207 – Clicking hotbar hotkey (1-9) to move a stack of items/blocks to enchanting table deletes all but one of a stack.

• 14w02a was previously removed from the launcher for some time, but was added back in September 2018.
• As with 14w02b and 14w02c, this snapshot has the same protocol version as 1.7.6–1.7.10. Crossplay is therefore technically compatible between these versions but can cause issues.
