17w50a is the eleventh snapshot for Java Edition 1.13, released on December 11, 2017^[1]. This is the final snapshot released in 2017.

Additions

Command format

Added a new local coordinate type in commands using ^.
- When specifying coordinates in a command, the player can now use ^ to specify local coordinates instead of world coordinates.
- The axes used for local coordinates are relative to the rotation of the executing entity.
- Like world coordinates, they are measured from the base of an entity.
- The syntax is: ^left ^up ^forwards
- left/up/forwards is the amount of blocks in the specified direction.
- For example, typing /setblock ^ ^ ^3 stone in chat sets a stone block 3 blocks in front of the player in their view.
Tab-completing coordinates when not targeting a block suggests ~ ~ ~ again.

General

Tags

Added the default tags wooden_buttons and wooden_doors for both items and blocks.
The tags buttons and doors now include stone_button and iron_door respectively for both items and blocks.

Changes

Blocks

Ender chests

Now change their texture when the computer time is set to the 24th to 26th of December to suit Christmas.

Item frames

Can now be placed on the top and bottom of blocks.

General

Tags

Can now include other tags (of the same type).
- The player can add for example #foo:bar in a tag value list to reference another tag called foo:bar.
- Self-referencing is not possible.
When overriding a tag, the player can now choose to replace instead of append.
- By default all tags append if another data pack created the tag.
- Adding "replace": true to the tag definition makes that tag replace existing tags instead.
When used in commands, block tags now support block state and data tag arguments.
