Java Edition 1.18 experimental snapshot 6

1.18 experimental snapshot 6 is the sixth experimental snapshot for Java Edition 1.18, released on September 1, 2021, which introduces changes to terrain generation and tweaks biome placement.

Mobs

 * Horses, mules, and donkeys
 * Now follow players holding golden carrots, golden apples, and enchanted golden apples.


 * Llamas
 * Now follow players holding hay bales.

World generation

 * Aquifers
 * Aquifers under oceans or rivers are more likely to link to the underground.
 * More likely to find cave openings on ocean floors that actually lead somewhere instead of being cut off.
 * Caves at Y=0 to Y=40 which under oceans are more likely to be flooded.


 * Giant tree taiga and giant spruce taiga
 * No longer considered as cold climates.
 * Decreased the chance of mixed in with snowy biomes, caused a small reshuffle of other biomes to maintain the overall balance.


 * Grove and snowy slopes
 * Decreased the chance of generating on mountain peaks.
 * Altered generation so that they tend to spawn farther away from contrasting temperatures.


 * Springs
 * Slightly reduced the number of water springs.


 * Swamps
 * Now generate in dry areas.
 * Decreased the chance of being fragmented.


 * Canyons
 * Underwater variants readded
 * No longer use a specific carver for underwater canyons. Instead, they generate on ocean floors, using normal noise caves and carvers.
 * Now have more natural variation.


 * General
 * Decreased the chance of generating cold microbiomes.
 * Slightly increased the number of underwater magma blocks, to increase the chance of finding air when diving in aquifers.
 * Cave carvers can now carve through sand and gravel on ocean floors.

Fixes

 * Fixed decreased generation rate of lush caves.
