Minecraft has been one of the most popular sandbox games over the years. Mojang Studios is gearing up to launch the 1.17 Update for the game, also known as the Caves and Cliffs Update which will be adding a plethora of new content to the game.

MORE FROM MINECRAFT: Minecraft Bedrock Beta Update – Patch Notes (Today, March 11)

Ahead of the release of the Caves and Cliffs update, the developers have been releasing a number of snapshots and beta updates to test some of the features upcoming Caves and Cliffs. A few weeks ago, Glow Squids made their way into the game via a snapshot and it quickly became a hit in the community. The last snapshot added Lush Caves to the biome alongside numerous other bug fixes and performance improvements.

When will Snapshot 21w11a release?

Minecraft Snapshot 21w09a was slated to release a couple of weeks ago but it was canceled due to some reason. We got the Lush Cave snapshot after that and a new Snapshot comes out every week. Snapshot 21w11a has already been released and is available for download.

Minecraft Snapshot 21w11a – Patch Notes


Lightning rods can now, for the very first time ever, be waterlogged

New functionality for applying and removing wax from Copper

Bonemealing rooted dirt now grows hanging roots underneath


Right-click with Honeycomb on Copper Blocks to wax them

Use honeycomb in a dispenser to wax Copper Blocks

Axes can scrape off wax and oxidation of Copper Blocks

Lightning strike hitting Copper will clean its oxidation


Waxed Copper Blocks can be crafted into 4 Copper Ingots

Tweaked the cave sizes

Slightly increased the frequency of Diamond Ore blobs

Hanging roots block now renders randomly offset

Breaking a Big Dripleaf stem now drops a Big Dripleaf Block

Moss Blocks can be crafted with cobblestone or stone bricks to make the mossy versions of those blocks

The facing direction of Small Dripleaf Blocks is now determined by which direction the player is facing when placing it

Fully-grown Amethyst Clusters now drop 4 Amethyst Shards (or more with Fortune) when mined with a pickaxe, and drop 2 Amethyst Shards when broken by hand, piston, or other means


Added F3+L shortcut to generate and persist performance metrics from in-game


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. These will be saved to a zip file in debug/profiling/

.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, and our plan is to continue iterating on which metrics to capture.
