Download

Patch 20.3.3

Fixes:

  • Fixed crash caused by the biome music

Release 20.3.2

Changes:

  • Changed the texture of the Axe of Regrowth.
  • The Axe of Regrowth now replants saplings on the same block that was broken instead of the one below.
  • If Woodworks or Quark are installed, the chests in the temple will be replaced with jungle chests.

Release 20.3.1

Main changes:

  • Phantom Library is no longer required. It was a fun experiment, but it only made things more likely to crash.

Additions:

  • Jungle spores can now be collected from jungle vines.
  • Added the Axe of Regrowth, an axe that can replant saplings when chopping down trees.
  • Added the Blade of the Jungle, a sword that has a 10% chance to inflict poison on hit.
  • Amethyst geodes in the underground jungle have been replaced with "honey geodes".

Changes:

  • Changed the texture of the temple key to match the upcoming trial key.

Fixes:

  • Fixed crash when generating giant mushrooms underground.

Release 20.3.0

Main changes:

  • Underground Jungle now requires the Phantom Library.
  • The version number now follows the convention <minecraftMajor>.<minecraftMinor>.<modVersion>. That means version 20.3.0 is the first version for Minecraft 1.20.3.

Additions:

  • Added ru_ru language

Fixes:

  • Fixed the biome generating on the surface when TerraBlender is installed (for real this time... I hope)
  • Fixed crashes in versions past 1.20.2
