Changes[edit]

Blocks[edit]

Activator rails & powered rails
  • Powered rails and activator rails no longer transmit power to each other.
Beacon
  • Now drops any contained item when exiting the GUI.
  • No longer accepts items from hoppers.
  • PaymentItem NBT tag removed.
Cactus
  • Breaks if lava is adjacent.
  • Cactus on sand breaks if water or lava is in the block above.
Cobweb
  • Cobwebs now catch snowballs, eggs, thrown potions, XP bottles, and ender pearls, causing the item form of the projectile to be dropped.
Crops & Nether wart
  • Hitbox now changes as the plant grows.
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.
Elytra
  • Increased damage when flying into a wall.
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.
Fire
  • Chance of going out in rain increased by 20 percentage points (now 20% + 3 percentage points per age).
Furnace
  • The lit_furnace block is no longer available as an item.
Lily pads
  • Bounding box changed, now 15/256 high (from 1/16) and inset from three edges of the block by 1/16.
Pistons
  • Unextended pistons, downward-facing pistons, and upward-facing piston extensions are now considered to have a solid top surface, like upside-down stairs and top-half slabs.
    • Among other things, this means mobs can now spawn on them.
Tripwire and 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.
Trapped chest
  • Now appears in the Redstone tab of the Creative inventory instead of Decoration Blocks.

Items[edit]

Melons
  • Melons and glistering melons are now oriented the same way (Removed in 15w49b).

Mobs[edit]

General
  • Improved pathfinding
  • Knockback no longer changes the Y-axis speed of flying and falling mobs.
Cave spiders, endermites, magma cubes, silverfish, slimes, spiders, wither skeletons, zombies, zombie pigman
  • Now fight back when hit by other mobs.
Ender dragon
  • Can no longer ride anything.
  • Can no longer have status effects.
Enderman
  • Can no longer pick blocks from behind walls.
Horse
  • Now rotates with the player.
Shulker
  • No longer float above the ground.
Skeleton
  • No longer find shade to hide under if equipped with a helmet.
Snow golem
  • Using shears on a snow golem removes the pumpkin head (and remove 1 durability from the shears).
    • The pumpkin is not dropped.
Wither

Non-mob entities[edit]

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.
Bottles o' enchanting, eggs, ender pearls, snowballs, thrown potions
  • No longer collide with non-opaque blocks.
    • Even non-opaque blocks that are solid, such as glass (see MC-93636).
  • Are "caught" and converted to the item form by cobwebs.
  • 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 fly slower, and an arrow fired sideways has motion in the direction of minecart travel.
SmallFireball entity
  • No longer damages (or angers) fire-immune entities.

World generation[edit]

End portal
  • In the 0.0000000001% chance that all 12 frame blocks generate with eyes already present, the portal is immediately activated.
    • This means once again, it is possible to access the End without going to the Nether.

Command format[edit]

/playsound
  • Now auto-completes itself when pressing TAB.
/particle
  • Now has an optional player parameter to specify which players can see the particle when inside the range. When left out, everyone in range can see the particles.
    • Also added a params parameter to specify particle parameters (for iconcrack_, …).
Sound events
  • Renamed entity.arrow.successful_hit to entity.arrow.hit_player.

Gameplay[edit]

Combat
  • Sweep attacks now do 1♥ damage to mobs affected by the knockback.
  • The Infinity enchantment no longer affects spectral and tipped arrows.

  • Sneaking now increases exhaustion by half as much as walking.
Frost walker enchantment
  • Now functions whenever the player is standing on ground, regardless of whether the ground is a solid block or not.
  • No longer works on armor stands.
Lightning
  • No longer destroys item frames, leash knots, paintings, and armor stands.
Status effects
  • Health Boost effect now shows multiple red hearts instead of the one similar to Regeneration.
  • Absorption effect now shows a single red heart with a yellow outline around it.
  • Nausea effect now stops instantly when cleared using Milk or with commands.
