Command block
  • The character limit is now 32500 instead of 32767
End gateway block
  • Changed texture to be both angle and face independent.
    • The footprint of the visible faces, will always display the same texture without deforming due to perspective.
      • Therefore any edges of the block that are not part of the footprint will be invisible.
  • Changed the beam texture to be unique.


  • Extended potion of poison, potion of poison II, and extended potion of regeneration had their duration reduced.
  • Potion of strength changed from 130% bonus to damage to 3 () of bonus damage (from relative to absolute).
  • Potion of weakness changed from 0.5 ( × 14) reduction to damage to 4 ().
  • Throwable potions now behave like other projectiles when used in dispensers.
    • They travel a much greater distance.
Spawn eggs
  • Can no longer address spawn eggs by numeric data id, like: give @p spawn_egg 1 50.
    • The spawnable item from a spawn egg is now addressed by a datatag: give @p spawn_egg 1 {EntityTag:{id:"Creeper"}}.


  • The HealF Float tag has been renamed to Health.
    • As a result, the original Health tag is now a Float type rather than Short.
Ender dragon
  • Now shoots the previously added ender acid entities.
    • A fire charge 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 will get damaged.
  • Arrows get deflected and set on fire while the dragon is on top of the portal.

Command format[]

NBT tags
  • CommandStats can be used to obtain the number of scoreboard tags an entity has via QueryResult.
    • Example: /scoreboard players tag <targetname> list will return the number of "scoreboard tags" applied to the target.
      • If the target previously had 3 tags added, a score of "3" is returned.
  • Removed DataVersion from Entity. It is now only applied to Player only, child of LivingBase.
  • HealF under LivingBase has become deprecated.
  • Health under LivingBase has changed from type "Short" to "Float".
  • Life renamed to Age for EndGateway entity.
  • Equipment removed from ArmorStand and Living entity, its usage replaced by HandItems and ArmorItems which were added earlier.


Pick block
  • In Survival, pick block now works on items outside of the hotbar but inside the player's inventory.
  • In Creative, using pick block normally will give the player a new one instead of existing ones with NBT.
  • ctrl+middle click no longer replaces items.
    • Existing items are put into the inventory instead of being deleted.
  • Now show absolute damage instead of damage increase
