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.

WAXING COPPER AND OXIDIZATION

Axes can scrape off wax and oxidation of Copper Blocks

Lightning strike hitting Copper will clean its oxidation

CHANGES IN 21W11A

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

TECHNICAL CHANGES IN 21W11A

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

IN-GAME CLIENT METRICS REPORTING

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.
