World generation

 * The Nether

 * Mineral veins of soul sand now generate in soul sand valleys at level of the lava ocean.

Gameplay

Blocks

 * Blackstone

 * 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
