The snapshot server has been updated.
New Minecraft snapshot version is: 21w19a.
CHANGES IN 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
CHANGES TO THE CAVES & CLIFFS PREVIEW
Download the updated datapack.
- The pack now includes recipes related to bundles and candles
TECHNICAL CHANGES IN 21W19A
- 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
JAVA 16
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.
ITEM COMMAND
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.

PERFORMANCE METRICS REPORTING
These will be saved to a zip file in debug/profiling/<yyyy-MM-dd_HH.mm.ss-[levelname]-[version]>.zip and could be used for performance regression analysis if included in bug reports.
The exact metrics, output format, and names are susceptible to change between versions. Our plan is to continue iterating on which metrics to capture.
CLIENT F3+L SHORTCUT
Pressing F3+L while in the game will start a recording for 10 seconds capturing metrics such as tick durations, used heap sizes and other more detailed stats.
Pressing F3+L before the 10 second limit will end the recording early.
This shortcut is always available to clients, even on multi-player servers where it will record client-side performance.
DEDICATED SERVER PERF START/STOP COMMAND
perf start will start a recording for 10 seconds capturing metrics such as tick durations, used heap sizes and other more detailed stats.
perf stop before the 10-second limit will end the recording early.
