• No longer accepts items from hoppers.
• PaymentItem tag removed.

Minecraft:Cactus

• Breaks if lava is adjacent.
• Cactus on sand breaks if water or lava is in the block above.

Minecraft:Cobweb

• Now catches snowballs, eggs, thrown potions, XP bottles, and ender pearls, causing the item form of the projectile to be dropped.
  • Removed in Minecraft:15w49b.

Minecraft:Crops & Minecraft:nether wart

• Hitbox now changes as the plant grows.

Minecraft:Doors

• Are now placed facing left/right depending on which half of the block the player clicks on, unless neighboring doors cause them to place a certain way.

Minecraft:End crystals

• Now require air or replaceable blocks in the two blocks above the block it's being placed on.
• Can no longer be placed to intersect other entities.

Minecraft:Fire

• Chance of going out in rain increased by 20 percentage points (now 20% + 3 percentage points per age).

Minecraft:Furnace

• The lit_furnace block is no longer available as an item.

Minecraft:Lily pads

• Bounding box changed, now 15/256 high (from 1/16) and inset from three edges of the block by 1/16.

Minecraft:Pistons

• Unextended pistons, downward-facing pistons, and upward-facing piston extensions are now considered to have a solid top surface, like upside-down Minecraft:stairs and top-half Minecraft:slabs.
  • Among other things, this means mobs can now spawn on them.

Minecraft:Tripwire and Minecraft:tripwire hooks

• Removed the distinction between "suspended" and "non-suspended": formerly, tripwire would work only if the whole stretch and both hooks were all above solid blocks or all not above solid blocks.

Minecraft:Trapped chest

• Now appears in the Redstone tab of the Creative inventory instead of Decoration Blocks.

Items

Minecraft:Elytra

• Increased damage when flying into a wall.

• Knockback no longer apply on the Y-axis of gliding and falling entities.<ref>Template:Bug</ref>

Minecraft:Cave spiders, Minecraft:endermites, Minecraft:magma cubes, Minecraft:silverfish, Minecraft:slimes, Minecraft:spiders, Minecraft:wither skeletons, Minecraft:zombies, Minecraft:zombie pigmen

  • The pumpkin is not dropped.

Minecraft:Wither

• No longer teleports through Minecraft:Nether portals or Minecraft:End portals.

Non-mob entities

Minecraft:Arrow entity

• Now take the thrower's motion into account. For example, an arrow fired forward by a player in a speeding minecart flies faster relative to the ground, an arrow fired backward flies slower, and an arrow fired sideways has motion in the direction of minecart travel.
• Arrows that bounce off a target (e.g. a shield or a sitting dragon) and may be retrieved become dropped items if near zero momentum after being bounced.
