 * Burning skeletons have a 50% chance of shooting flaming arrows if raw regional difficulty is 3 or greater.


 * Villagers
 * Now run away from nearby husks.

 * Will drink a potion of fire resistance if they don't already have the effect and the most recent damage taken (within the past 2 seconds) was fire damage.


 * Zombies

 * Chance is now (30 × RegionalDifficulty)%; formerly 30% on Easy, 60% on Normal, 90% on Hard.

 * Villages in savanna and taiga biomes now use the appropriate type of wooden fences.
 * Cobblestone now generates around wells instead of gravel.
 * Paths now only replace grass blocks with air above water, lava, sand, sandstone, and red sandstone. All other blocks will be ignored, with blocks below (down to sea level) considered for replacement instead.
 * This allows paths to generate properly under trees.
 * This removes the ability for paths to bridge ravines.
 * Zombie villagers generated in zombie villages no longer despawn (i.e. they have the  flag set).
