We still highly recommend backing up your world before loading it in this snapshot.

Changes in 21w40a

  • World generation tweaks
  • Changes to mob spawning
  • Copper Ore now drops 2-5 (from 2-3) Raw Copper items
  • In the Stonecutter, a Block of Copper can be converted to four Cut Copper
  • A bunch of biome variant with similar features but different shapes have been merged into one, since the shape is controlled independently now
  • Renamed some biomes

World Generation

  • Updated ore distribution to make branch mining deep down more rewarding. Updated ore distribution chart
    • For example, added more unexposed diamonds
    • Iron ore now generates above 80, with more iron ore as you go higher
    • Extra gold generates below height -48
  • Non-cave biomes no longer change with height - so no more savannas in the sky and things like that
  • Tweaked the relative size of some biomes to match 1.17 a bit closer.
  • Increased the average size of most biomes (this also means biomes aren't in the same places as before)
  • Fixed some aquifer issues (a side effect of this is that aquifers are in different places now compared to last snapshot)
  • Slightly increased the frequency of underwater magma
  • Increased the amount of dungeons, especially below height 0
  • Gravel now generates below height 0
  • Villages are slightly more spread out
  • Removed water lake features, Aquifers provide local water levels

Mob Spawns

  • Axolotls now only spawn in water, above clay blocks, in lush caves
  • Glowsquids now only spawn in water blocks, under height 30
  • Cod, Salmon, Pufferfish, Tropical Fish, Squid and Dolphins now only spawn in water from height 50 to height 64
  • Tropical Fish now also spawn in lush caves at any height
  • Zombies once again spawn in dripstone caves - drowned can also spawn there however
  • Goats no longer spawn in stony peaks

Technical Changes in 21w40a

  • Optimized AI for Axolotls, Goats, Hoglins, Zoglins, Piglins, Piglin Brutes and Villagers
