Java Edition 15w33a

15w33a is the seventh snapshot for Java Edition 1.9, released on August 12, 2015,^[1] which adds dragon's breath and lingering potions.

Dragon's breath

• Found in the brewery section of the Creative inventory.
• Can be used to brew lingering potions by brewing it with a splash potion.
• Can be obtained by using  Right Mouse Button with a glass bottle while the ender dragon breathes the homonymous attack.
• Stacks to 64.

Lingering potion

• Thrown like a splash potion.
• Leaves a particle cloud made of the effect particles of the corresponding potion.
  • Entities that walk into the cloud get the corresponding effect.
• Has variants for every potion type, and works with potions whose effect are instant, like Harming.
• Brewed with dragon's breath and the corresponding splash potion.
  • The only way to do this is to brew the splash potions from normal potions and leave them in the slots of the brewing stand. Then add the dragon's breath.
• The cloud duration can be controlled through a data tag.

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.

Statistics

• Per-item statistics for number dropped and number picked up.
  • stat.pickup and stat.drop.

Splashes

• Added "More Digital!"

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.

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 3HP of bonus damage (from relative to absolute).
• Potion of Weakness changed from 0.5HP × 0.25 reduction to damage to 4HP.
• 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"}}.

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.

NBT format

• 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 gives the player a new one instead of existing ones with NBT.
• ⎈ Control+ Middle Mouse Button no longer replaces items.
  • Existing items are put into the inventory instead of being deleted.

Tooltips

• Now show absolute damage instead of damage increase.
