'''13w42a''' is the twelfth [[Minecraft:snapshot]] for [[Minecraft:Java Edition 1.7.2]], released on October 17, 2013.<ref>{{cite|url=https://www.mojang.com/2013/10/minecraft-snapshot-13w42a/|archive=y|title=Minecraft snapshot 13w42b (Updated!)|author=[[Minecraft:Dinnerbone]]|website=Mojang.com|date=October 17, 2013}}</ref> It allows for more letters to be put on signs, change the texture of [[Minecraft:stained glass]] and makes [[Minecraft:witch]]es a common monster (like creepers and zombies) instead of spawning exclusively in and around [[Minecraft:witch hut]]s.

== Changes ==
=== Blocks ===
'''[[Minecraft:Sign]]s'''
* Different letters can be typed now.

'''[[Minecraft:Stained glass]]'''
* Have a smoother/transparent texture.

'''[[Minecraft:Stained glass pane]]s'''
* Have a smoother/transparent texture.
* The crafting recipes now yield 16 panes instead of 6, to be consistent with regular glass panes.

'''[[Minecraft:Water]]'''
* Transparency slightly adjusted.
* If water is directly adjacent to [[Minecraft:ice]], when looking through the ice, the player cannot see the water.
** However, the player can see the ice when looking through water.
** If water is not directly adjacent to ice, the player can see the water when looking through the ice.<ref>{{tweet|Dinnerbone|390926161091768320|It's a bug, don't expect it to stay sorry. :( The behaviour is very unreliable and it's part of bigger issues.|October 17, 2013}}</ref>
* The player can no longer see the water surface from underwater

=== Items ===
'''[[Minecraft:Map]]s'''
* Now display the color of colored [[Minecraft:wool]] and [[Minecraft:stained clay]], allowing a wider range of colors visible on maps.
* Each different type of [[Minecraft:block]] has a different shading on the map.

=== Mobs ===
'''[[Minecraft:Witch]]es '''
* Now spawn anywhere where the light level is 7 or less, including any biome and underground.

'''[[Minecraft:Zombie]]s'''
* Can only break doors when having the new CanBreakDoors tag set to 1, an up to 10% chance.<ref>https://www.reddit.com/r/Minecraft/comments/2qqgcx/til_minecraft_18_changed_how_zombies_break_doors/</ref>

=== General ===
'''[[Minecraft:Inventory]]'''
* The armor boxes get black when empty and away from cursor.
* Putting cursor over the armor inventory displays which armor is to put on there.

'''[[Minecraft:Resource pack]]s'''
* Rewrote the sound system.
** The player is now able to add new sounds using resource packs.
* Resource packs can now add, remove, supplement, randomize, and group sounds using JSON.
* Sounds and music are now stored together in the new .minecraft/assets/sounds folder.

== Trivia ==

* 13w42a was previously removed from the [[Minecraft:launcher]] for some time, but was added back in September 2018.
