'''17w49a''' is the ninth [[Minecraft:snapshot]] for [[Minecraft:Java Edition 1.13]], released on December 6, 2017<ref>{{snap|17w49a|December 6, 2017}}</ref>, which adds block and item tags and fixes bugs.<br />
<br />
== Additions ==<br />
=== General ===<br />
'''[[Minecraft:Tag]]s'''<br />
* Items and blocks can now be "tagged" with an ID.<br />
** Block tags can be used when testing for blocks in the world.<br />
** Items tags can be used when testing for items in inventories.<br />
* Tags are created using [[Minecraft:data pack]]s in <code>data/(namespace)/tags/blocks</code> or <code>data/(namespace)/tags/items</code>.<br />
** For example: <code>data/(namespace)/tags/blocks/foo.json</code>.<br />
** This creates a block tag called <code>(namespace):foo</code>.<br />
** The json file contains a list of all blocks that should be "tagged".<br />
* There are two default tags for both the item form and the block form: <code>minecraft:wool</code> for all wool blocks and <code>minecraft:planks</code> for all wood plank blocks.<br />
<br />
== Changes ==<br />
=== General ===<br />
'''Crafting'''<br />
* Recipes can now refer to a tag instead of an item.<br />
<br />
== Fixes ==<br />
