Snapshot for



Client (.json)

15w40a is the twenty-ninth snapshot released for 1.9.[1]

Changes[edit | edit source]

  • Changes to mob pathfinding.
    • Mobs now avoid cacti and fire.
    • Passive mobs following a player holding food will now go around water, if possible.
  • Entities panicking and on fire will preferentially run towards water within ±5 blocks horizontally and ±4 blocks vertically, even if they can't actually reach it.
  • Shulkers
    • No longer attack in peaceful difficulty.
      • Shulker bullets despawn in peaceful, but not shulkers themselves.
  • Health regenerates 1 (Half Heart.svg) every half-second instead of 1 (Half Heart.svg) every 4 seconds, when saturation is not empty.
    • Regenerating health increases exhaustion by 4 points rather than 3.
