Rabbit
- Smaller than before.
- Chance to drop the rare drop, rabbit's foot, is 4× what it was before.
- Now only spawn in deserts, flower forests, taiga, mega taiga, cold taiga, ice plains, ice mountains, ice plains spikes, and "hills" and "M" variants of these biomes. Even in these biomes, spawn chance is somewhat reduced (weight 4 out of 44–52 rather than 10 out of 50–58).
- Can now spawn on sand.
- Rabbits are faster when panicking.
- Rabbits no longer prefer begging for food to mating.
- Non-killer rabbits now avoid players within 8 blocks and most hostile mobs within 4 blocks (except slimes, magma cubes, and ghasts), and move faster when doing so. Also, avoidance range for wolves was reduced from 16 to 10 blocks.
- Health reduced to 3 (Heart.svgHalf Heart.svg).
- Naturally-spawned rabbit's skin depends on the biome. When breeding rabbits, there is a 5% chance the baby will match the biome rather than either parent.
- In a snowy biome, 80% white and 20% black & white.
- In a desert or desert hills, 100% gold.
- Otherwise, 50% brown, 40% salt & pepper, 10% black.
- MoreCarrotTicks no longer has any effect.
- When destroying crops, MoreCarrotTicks is set to 40 rather than 100.
- Destroying carrot crops now reduces the growth stage by 1 level, only removing the crop block entirely if the growth stage was 0.
- New sounds for when the killer bunny is attacking.
Iron golem
- Are slightly shorter (2.7 blocks tall rather than 2.9).
- All newly spawned iron golems have 100% knockback resistance.
Mob spawning
- Mobs can no longer spawn inside blocks that block movement but are transparent, such as leaves.
- Mobs can no longer spawn in blocks containing rails, powered rails, detector rails, or activator rails.
- Mobs can no longer spawn in blocks containing buttons, tripwire hooks, pressure plates, levers, redstone torches, redstone repeaters, comparators, or redstone dust
Skins
- Overlay layers (hat, jacket, sleeves, and pants[Verify]) correctly render semitransparent pixels, instead of only fully opaque and fully transparent pixels.
Cobwebs
- Can now turn thrown items in to item form.
Infinite Potion Farms
Using the cobwebs you can place cobwebs over hoppers and have a witch on the other side of the cobwebs, then you yourself will go on the side where the witch isn't there. Over time the witch will notice you and start throwing potions the potions will hit the cobweb, turn in to te item form go into the hopper to the chest.
