Minecraft Beta Version 1.17.20.22

We have another Bedrock Beta update today, and we've fixed a bunch of bugs! Also, we've made a fairly significant change to the way hostile mobs spawn – to test this out you'll need to enable the Caves and Cliffs Experimental Features. We're hoping this change will make your cave spelunking trips slightly safer, but you'll still need to avoid falling in lava with a hotbar full of diamonds. Not that that ever happens, right?

Please continue to send us your feedback in the pinned threads at aka.ms/CavesCliffsFeedback, and search and report any new bugs you may encounter at bugs.mojang.com.

Experimental Features

• Monsters will only spawn in complete darkness  
  • This change is being made to balance the player's ability to light up the new larger caves and make them safe from monster spawning 
  • Note that this change only affects block-light and not sky-light 
  • Please send us your feedback on this change at aka.ms/CCMobSpawningFeedback!
