Java Edition 20w19a

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

World generation

 * The Nether
 * Mineral veins of blackstone and gravel now generate in all Nether biomes at level of the lava ocean.
 * Mineral veins of soul sand now generate in soul sand valleys at level of the lava ocean.

Gameplay

 * Statistics
 * Added a statistic for distance by strider.

General

 * Tags
 * Added block tag.
 * Contains the  block tag, as well as wither roses and sweet berry bushes.
 * Mobs cannot spawn in blocks in this tag.

Blocks

 * Blackstone
 * Now uses the top texture on the bottom face.


 * Crimson and warped doors
 * Texture changed to include hinges.


 * Crimson and warped roots
 * Are now randomly offset, similarly to grass and flowers.


 * 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 (see Distance effects in Java Edition).


 * Twisting vines and weeping vines
 * Lowered the amount that they grow when bone meal.

Mobs

 * General
 * 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.


 * Fish
 * Now have their own mob category and mob cap.


 * Hoglins and piglins
 * Now become zoglins and zombified piglins respectively when in the End.


 * Iron golems
 * Villagers can now spawn iron golems regardless of their profession status or latest working time.

World generation

 * The Nether
 * Bastion remnants are now slightly less common.
 * Tweaked biome distribution.

Gameplay

 * Creative inventory
 * Block categories and tag names are no longer bold.


 * Recipe book
 * Clocks and compasses no longer function in the recipe book menu.

General

 * Tags
 * Changed the block and item tags to use their respective  tag.
 * This has effectively made crimson stairs and warped stairs a part of this tag.
