Java Edition 15w40a

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

Mobs

 * General
 * Changes to mob pathfinding.
 * Mobs now avoid cacti and fire.
 * Blazes will not avoid 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 cannot actually reach it.


 * Shulkers
 * No longer attack in peaceful difficulty.
 * Shulker bullets despawn in peaceful, but not shulkers themselves.

Gameplay

 * Health
 * Health regenerates every half-second instead of  every 4 seconds, when saturation is not empty.
 * Regenerating health increases exhaustion by 4 points rather than 3.
