Java Edition 23w13a or b

23w13a_or_b is an April Fools' joke snapshot, supposedly the first and only snapshot for the "Vote Update", released on April 1, 2023, which adds a system where players vote for gameplay features or mechanics to be implemented. This snapshot is a fork of 23w13a.

The snapshot was reuploaded about three hours after the release, to fix some crashes related to transformations and to remove inappropriate color names.

Trivia

 * Bartosz Bok showed a video of a minecart with 3d wheels 3 years ago.
 * The Wob item either appears to be a reference to a common crafting misconception. A post about this was made on Twitter that tagged the YouTuber PhoenixSC, who made a concept for this and seems to be the inspiration for the feature.
 * The "Trails & Tails" rule could also be a reference to a PhoenixSC video based off a misspelling of the update's title in an official article. The typo since has been fixed.
 * The "No Round Shapes Allowed" cape may be a reference to the YouTuber Mysticat, who is known for creating a circle using only command blocks in Minecraft. This is mainly supported due to the background of the cape matching the YouTuber's skin.
 * The "181 Choices" splash doesn't exist in the  file, but is generated by the game on startup instead.
 * Rule and  contain a misspelling of lava, based off a bug that appeared in 22w44a.
 * Rule can be "Replace 'k' with 'K'", which causes the miscapitalization of "block" into "blocK", based off a bug that appeared in 20w45a.
 * This is the second version of Minecraft, where the player can go to creative mode without cheats, the first being ???(idk the version, but u had to press 'B'. probably 1.0 or so). This is done by crafting a spawn egg (type is not relevant) with the nbt tags, that summons a repeating command block minecart executing "/gamemode <Playername> 1".
 * This is the first Minecraft Version that allowes the player to get any item/block with any nbt tags without cheats by getting a repeating comand block minecart executing "/fill <...>" or "/summon " (see above).
 * It is also possible to "nuke" a server with such a minecart similar to Bedrock Edition.
