Additions

General

Realms

Changes

Blocks

Minecraft:Lily pads

• Collision box was raised from Template:Frac of a pixel to 1 pixel in height.

Items

Minecraft:Maps

• Are crafted at a zoom level of 1:1, as was the case before Minecraft:15w34a.
  • Can no longer be zoomed in.
• This reverts maps to 1.8 behavior.

Minecraft:Shields

• Placing a pattern on a shield now consumes the Minecraft:banner.

Mobs

Minecraft:Elder guardians

• Rare drops now only provide fish, as they had in 1.8 versions, eliminating fishing treasure and fishing junk that had been seen in snapshots.

Minecraft:Shulker

• Added sounds for shulkers getting damaged.

Non-mob entities

Minecraft:Boats

• The dark oak boat can now be crafted.

Command format

General

• Tab-completed coordinate arguments now become tildes if no block is in focus.

Minecraft:NBT format

• The Linger byte tag on ThrownPotion entities has been removed.
  • Instead, the potion lingers if the stored item has an ID of minecraft:lingering_potion.
  • The following command creates a ThrownPotion lingering potion: /summon ThrownPotion ~ ~5 ~ {Potion:{id:"minecraft:lingering_potion",tag:{Potion:"minecraft:swiftness"}}}.
• The ThrownPotion renders as its stored item, no matter the item.
  • For instance, if the stored item has an ID of minecraft:diamond_sword, the potion appears as a diamond sword while being thrown.
