Additions[edit | edit source]

Items[edit | edit source]

Dragon's breath
Lingering potion
  • Thrown like a splash potion.
    • Leaves a patch of the potion particle effect.
      • Entities that walk into it get the effect.
  • Has all the potion types, and works with potions whose effect are instant, like Harming.
  • Brewed with dragon's breath and the corresponding splash potion.
  • The cloud duration can be controlled through a data tag.
  • Doesn't stack, like other potions.

Command format[edit | edit source]

NBT format
  • Added entity AreaEffectCloud (ID 3), child of Entity.
  • Added tags Age, Duration, WaitTime, ReapplicationDelay, DurationOnUse, RadiusOnUse, RadiusPerTick, Radius, OwnerUUIDLeast, OwnerUUIDMost, Particle, Color, and Effects to AreaEffectCloud.
  • Added ExactTeleport to EndGateway.
  • Added Linger to ThrownPotion.
Scoreboard
  • New objective types: armor and level.
    • "armor" tracks the armor bar, that indicates the total protection from all currently worn armor pieces.
    • "level" tracks the level of the player which is the number above the experience bar and not the amount of xp points.

General[edit | edit source]

Statistics
  • Per-item statistics for number dropped and number picked up.
    • stat.pickup and stat.drop.
Splashes
  • Added "More Digital!"

Changes[edit | edit source]

Blocks[edit | edit source]

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 always displays the same texture without deforming due to perspective.
      • Therefore any edges of the block that are not part of the footprint are invisible.
  • Changed the beam texture to be unique.

Items[edit | edit source]

Potions
  • 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♥ × 0.25 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"}}.

Mobs[edit | edit source]

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.
Ender dragon
  • 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[edit | edit source]

NBT format
  • CommandStats can be used to obtain the number of scoreboard tags an entity has via QueryResult.
    • Example: /scoreboard 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.

General[edit | edit source]

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 gives 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.
Tooltips
  • Now show absolute damage instead of damage increase.
