This page covers a development version that has a major issue under certain conditions.
 
The dedicated server for this version has a security vulnerability in the Log4j library that could be used to perform a remote code execution exploit. It can be addressed by appending a certain JVM argument to the server startup command line.[1]

General

[edit | edit source]

NBT format

  • Spawners now have a new [NBT Compound / JSON Object] CustomeSpawnRules [sic] tag, which lets players override the spawn rules of the spawned mob.
    • In the tag, players can specify [Int] BlockLightLimit, which indicates the highest block-light the spawner spawns mobs at.

Changes

[edit | edit source]

General

World generation

[edit | edit source]

Beaches

  • Beaches are generally wider.
    • In some places there is a chance where no beaches generate at all, to provide some variation.

Extreme hills

  • Renamed mountains to extreme hills, and gravelly mountains to gravelly hills.

Mountains

  • Sheep now spawn in meadows.
  • Rabbits now spawn more frequently in meadows.
  • Donkeys now spawn less frequently in meadows.
  • Blue orchid no longer spawns in meadows.
  • Meadows sometimes spawn a lone oak or birch, often with a bee nest.
  • Hostile mobs now spawn in the new mountain biomes.
  • Infested stone now generate in the new mountain biomes.

Ore distribution

  • Emerald ores now generate in the new mountain biomes.

Ore veins

  • Made ore veins slightly larger and more frequent.

Biomes

Swamp

  • Swamps now generate properly.

Lush caves

  • Are now slightly smaller and slightly less common.

General

  • Biome placement is a bit smoother and less noisy. Fewer microbiomes dotting the terrain. Biomes tend to be a bit larger and less fragmented.
  • Underground biomes interfere less with surface biomes. They can still leak out of cave entrances sometimes.
  • Increased the height of some of the peaks.
    • Now can rarely reach up to Y=260.
  • Slightly increased the chance of finding large areas with flat terrain.
  • Structures now mostly show up in the right biomes.
  • Toned down the megacave entrances a little bit, and made them less likely to go all the way down to deepslate level.
  • Made cheese caves a little bit smaller on average, and a bit less likely to intersect the surface.
  • Reduced the chance of sand and gravel being placed in such a way that they immediately fall down on generation.
    • Some are now replaced with sandstone or stone.

General

[edit | edit source]

Clouds

  • Raised cloud level from 128 to 192.
