'''15w46a''' is the 40th [[Minecraft:snapshot]] for [[Minecraft:Java Edition 1.9]], released on November 12, 2015.<ref>{{link|url=https://www.mojang.com/2015/11/minecraft-snapshot-15w46a/|archive-url=https://web.archive.org/web/20151113051511/https://www.mojang.com/2015/11/minecraft-snapshot-15w46a/|title=Minecraft snapshot 15w46a|author=Searge|website=Mojang.com|date=Nov 12, 2015}}</ref>

== Changes ==
=== Blocks ===
'''[[Minecraft:Banner]]s & [[Minecraft:sign]]s'''
* Now replace replaceable blocks such as [[Minecraft:grass]], instead of trying (and failing) to be placed on them.

'''[[Minecraft:Farmland]]'''
* Mobs smaller than 0.512 cubic blocks can no longer turn farmland to dirt by jumping or falling on it.
** This includes [[Minecraft:rabbit]]s, [[Minecraft:chicken]]s, [[Minecraft:bat]]s, [[Minecraft:ocelot]]s, [[Minecraft:wolves]], [[Minecraft:cave spider]]s, [[Minecraft:endermite]]s, [[Minecraft:silverfish]], small [[Minecraft:slime]]s, small [[Minecraft:magma cube]]s, and all current baby mobs.

'''[[Minecraft:Iron bars]]'''
* Their sides now include an edge texture.

'''Rails'''
* [[Minecraft:Powered rail]]s and [[Minecraft:activator rail]]s now transmit power to each other.

'''[[Minecraft:Redstone]]'''
* Hitbox for redstone is now smaller based on the connections, similarly to [[Minecraft:fence]]s.

'''[[Minecraft:Redstone block]]s'''
* Now emit power through adjacent blocks.
** Reverted in [[Minecraft:15w47a]].

=== Items ===
'''Filled [[Minecraft:bucket]]s'''
* Now replace single snow layers when {{control|used}} on the top, instead of placing the water or lava in the air above the snow layer.

=== Mobs ===
'''General'''
* Mobs can no longer spawn inside blocks that block movement but are transparent, such as [[Minecraft:leaves]].
* Also, mobs can no longer spawn in blocks containing any type of [[Minecraft:rail]]s, buttons, tripwire hooks, pressure plates, levers, redstone torches, redstone repeaters, comparators, or redstone dust.
* Something about rendering has changed; screenshots taken with the exact same position, viewing angle, FOV, etc. as an equivalent screenshot in 15w45a or earlier will differ.{{info needed|what changed, exactly?}}

'''[[Minecraft:Iron golem]]s'''
* If spawned in 15w46a and later, they have 100% knockback resistance.

'''[[Minecraft:Rabbit]]s'''
* Smaller than before.
* Chance to drop a rabbit's foot is now 10% + 3 percentage points per level of Looting (was 2.5% + 1 percentage point per Looting).
* 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).
* Are faster when panicking.
* 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 from {{health|10}} to {{health|3}}.
* Naturally-spawned rabbit's skin depends on the biome. When breeding rabbits, there is a 5% chance the baby matches 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.
* <code>MoreCarrotTicks</code> no longer has any effect.
** When destroying crops, <code>MoreCarrotTicks</code> is set to 40 rather than 100.
* Rabbits eating carrot crops now reduces the growth stage by 1 level, only removing the crop block entirely if the growth stage was 0.

'''[[Minecraft:Snow golem]]s'''
* No longer leave a trail of snow if the [[Minecraft:game rule]] <code>mobGriefing</code> is false.

'''[[Minecraft:Wolves]]'''
* Collar, when tamed, is now red, as it had been in releases before 1.8, rather than orange.

=== World generation ===
'''[[Minecraft:Ocean monument]]s'''
* Now require a 16 block square radius of deep ocean, not just a single deep ocean block at the center.

=== Gameplay ===
'''[[Minecraft:Experience]]'''
* Now is collected at the middle rather than at the head.
** This means that if a large amount of experience is collected, it no longer blocks the player's view.
* Blocks no longer drop XP when the <code>doTileDrops</code> gamerule is false.
