Java Edition 15w32b

15w32b was released to fix some bugs and crashes from 15w32a.

Additions

 * Scoreboard
 * Added
 * You can add and remove tags for any entity based on NBT tags of that entity/player.
 * For example will add the tag "test" to all players that are in the air.
 * Tags can be accessed by using the parameters after the selector; will give 1 stone to all players that have the tag "test".
 * You can use to see what tags are on an entity. (Note that in this current version, you can't use tab to get "list")
 * Tags are stored in the playerdata file as strings, not in the scoreboard files.
 * This means that any tag the player binds, has to be bound to an existing online player or an existing entity.
 * Unlike objectives, tags cannot be displayed on the sidebar or anywhere else.
 * Only via the list subcommand can you see which tags an entity has.
 * Added three new objective types: XP, hunger and oxygen.
 * "xp" can be used to track the players exact XP level without any intermediate step.
 * "food" can be used to track the hunger level of the player (ranges from 0 to 20).
 * "air" can be used to see for how long the player has been underwater.
 * Starts at 300 (out of water) and then decreases 1 per tick as long as the player's head is underwater (resets when the player exits the water).
 * The water breathing effect freezes the timer and the respiration enchantment slows down the countdown each time more with each level.
 * World selection screen
 * Now displays a thumbnail per world showing a glimpse of the world (it takes a screenshot when you have just created or opened it for the first time in this snapshot or higher).
 * When the world hasn't been opened in snapshot 15w32b or before, or if the game couldn't make a screenshot thumbnail, there will be a gray-scale image.
 * The thumbnail will be saved in the world folder under  with the name "icon.png".

Changes

 * Shulker
 * No longer teleport by themselves if  is set to 1.
 * Can now be teleported using or.
 * Creative Inventory
 * Removed Arrow of Splashing.
 * World selection screen
 * The exclamation mark from last snapshot, indicating that the world has not been played in the current snapshot yet, will now be shown on top of the thumbnail.
 * It will also warn if a world was played in a newer version of minecraft, telling the player that the world may corrupt, if they open it in an older version.
 * The version number will now display in red if it has been played in a newer version before.
 * The player can now click the play arrow on the thumbnail, just like a server, to open the world.
