14w03a is the fourth snapshot for Java Edition 1.8, released on January 16, 2014,^[1] which adds the /clone and /fill commands as well as /gamerule logAdminCommands.

/clone

• Clones all the blocks (not entities) from a given area to a different given area.
• Up to 4096 blocks can be copied.
  • • The clone can be masked or replace - replace copies every block, masked only copies non-air blocks.
  • Usage: /clone <x1> <y1> <z1> <x2> <y2> <z2> <x> <y> <z> [mode].
  • Example: /clone 1001 3 1002 1011 3 992 1001 5 992 masked.

/fill

• Fills a given volume with a specified block.
• Up to 4096 blocks can be filled.
  • oldBlockHandling works like with /setblock, but with additional options: hollow to only fill the outer layer of blocks and fill the inner part with air, outline to fill the outer layer of blocks and ignore the inner part.
• Works similarly to /setblock
  • Usage: /fill <x1> <y1> <z1> <x2> <y2> <z2> <TileName> [dataValue] [oldBlockHandling] <dataTag>.
  • Example: /fill 1001 3 1002 1011 5 992 wool 6 replace.

Gamerules

• logAdminCommands
  • If set to false, prevents all command blocks from outputting to the client console.
  • If used on a server, it also does not log player executed commands in the server's log.
• Players still see other players' executed commands in chat.

Player heads

• No longer only have one layer.

Iron golems

• Now only drop iron ingots when killed by the player, either through combat or potions, or player-activated mechanisms such as manually lit TNT.
• If killed without player intervention, only drops poppies.

Villagers

• When struck by lightning, now transform into witches, similar to pigs transforming to zombie pigmen and creepers to charged creepers.

Zombie pigmen

• Now only drop gold nuggets and rare drops when killed by the player, either through combat or potions, or player-activated mechanisms such as manually lit TNT.
• If killed without player intervention, only drops rotten flesh.

Desert pyramids

• Now spawn with stained clay 👁 Image
  rather than wool 👁 Image
  .

Villages

• Now spawn with cobblestone under the gravel pathways.

/tp

• Now supports rotation arguments.
  • Example: /tp @p ~ ~ ~ ~20 ~40 teleports the player so that they face 20 degrees to the right and 40 degrees downwards.

Target selectors

• Now supports cubic areas.
  • Example: @e[x=0,y=0,z=0,dx=10,dy=10,dz=10] gets all entities between 0,0,0 and 10,10,10.
• The radius value in selectors is now based on the block center.
  • A radius of 0 works for exact block positions.

Item tooltips

• Now shows the internal name for use in commands ( +  mode).

Block IDs

• NBT data in commands can now use block/item names in place of numerical IDs.
• Old IDs still work, but are being phased out slowly.
• Other occurrences of blocks/items now need to be named IDs.
• Regular IDs in commands no longer work. /give [player] 1 is now /give [player] stone.

F3 hotkeys

• + : Clear chat history (including previously typed commands).

Skin customization

• Uses a char.png file with new layout and new dimensions.
  • Dimensions for the file are now 64×64.
• Right and left arms and legs are now editable independently.
• The hat layer is now full-body, can be transparent.
  • Overlays for arms, legs, head, and body are called sleeves, pants legs, hat, and jacket respectively.
• Backward-compatible with older skins.
  • Old skins still work, but do not have the new features.
  • New skins when used in pre-14w02a versions act like old skins.
• New "Skin Customization" button in the options menu.
  • Cape visibility is now toggled from here.
  • Players can toggle the visibility of overlays, independent for each limb/body part.
