20w19a is the fifteenth snapshot for Java Edition 1.16, released on May 6, 2020,[1] which fixed bugs and made tweaks to mob spawning.


World generation[]

The Nether


  • Added a statistic for distance by strider.





  • Now uses the top texture on the bottom face.
Crimson and warped doors
  • Texture changed to include hinges.
Crimson and warped roots
Nether sprouts
  • Now require shears to be obtained.
  • Are now randomly offset, similarly to grass and flowers.
Redstone wire
  • Now visually connects when traveling up soul sand, 8-layer snow stacks and the back of upside-down stairs.
  • Particles are now generated across the entire area of the redstone wire; previously they only appeared at the center.
    • This now causes the particles to appear at the incorrect positions when millions of blocks away from the spawn point, due to precision loss[2] (see Java Edition distance effects).
Twisting vines and weeping vines
  • Lowered the amount that they grow when using bone meal.


  • Mobs can no longer spawn within blocks occupied by a wither rose (except wither skeletons).
  • Spawning has been tweaked to more closely follow mob caps.
    • Mobs in soul sand valleys and warped forests will create a radius around them that prevents other mobs of the same type from spawning, which gets bigger as more mobs spawn.
  • Now have their own mob category and mob cap.
Hoglins and piglins
Iron golems

World generation[]

The Nether


Creative inventory
  • Block categories and tag names are no longer bold.
Recipe book
