Minecraft 1.17 Snapshot 21w19a – Patch Notes

Here are the patch notes of the Minecraft Snapshot 1.17 21w19a.


  • The maximum length of item names in the anvil UI has been increased from 35 to 50
  • Made geodes significantly rarer
  • Unfinished items (Sculk Sensor, Bundles, and Candles) have been removed from the creative inventory
  • Recipes for unfinished items (Bundles, Candles) have been removed


  • The pack now includes recipes related to bundles and candles


  • Upgraded to Java 16
  • Added mineable/axe, mineable/hoe, mineable/pickaxe and mineable/shovel block tags. Blocks with these tags can be destroyed more quickly with the matching tool.
  • Added needs_stone_tool, needs_iron_tool and needs_diamond_tool block tags. If a block requires the correct tool to drop, these tags determine which tier of that tool is required.
  • Changed the syntax of the /item command


Minecraft now uses a more recent version of Java. If you are using a default setup the Launcher will download and install the correct version. If you are using a custom Java setup or a third-party launcher, you will need to ensure that your Java installation is version 16 or above.


New syntax:

  • /item replace <target> with <item stack> [<count>] – same as old replaceitem
  • /item replace <target> from <source> [<modifier>] – copies item for source to target(s), optionally applying modifier
  • /item modify <target> <modifier> – modifies item (without copying)

For example, /item replace block ~ ~ ~ container.0 from entity @s enderchest.0 will copy first item from player’s enderchest to first slot of container player is currently standing on.
