  • Cactus on sand will break if water or lava is in the block above.
  • Cobwebs now catch snowballs, eggs, thrown potions, XP bottles, and ender pearls, causing the item form of the projectile to be dropped. (Removed in 15w49b)
Crops and nether wart

Powered rails and activator rails
  • Powered rails and activator rails no longer transmit power to each other.

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


All mobs
  • Improved path finding

Non-mob entities[]

Arrow entity
  • Now take the thrower's motion into account. For example, an arrow fired forward by a player in a speeding minecart will fly faster relative to the ground, an arrow fired backwards will fly slower, and an arrow fired sideways will have 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 will become dropped items if near zero momentum after being bounced.
SmallFireball entity
  • No longer damages (or angers) fire-immune entities.
Thrown projectiles (snowballs, eggs, ender pearls, bottles o' enchanting, and thrown potions)

  • /playsound now auto-completes itself when pressing TAB.
