Minecraft Snapshot 21w20a

Another snapshot is now going out. This time around, we fixed quite a few bugs, and we also introduced some changes to some Caves & Cliffs features, and additionally, we added some extra context for the narrator.

Changes in 21w20a#

• Actually made geodes rarer this time
• GUI narration now includes position and usage of hovered or focused element
• Tilling rooted dirt with a hoe will now convert it into dirt, and pop out a hanging roots item
• Axolotls will now only play dead when in water
• Llamas no longer spit at players in peaceful mode

Technical changes in 21w20a#
