Java Edition 1.18 experimental snapshot 3

1.18 experimental snapshot 3 is the third experimental snapshot for Java Edition 1.18, released on August 10, 2021, which makes numerous changes to world generation and bug fixes.

World generation

 * Aquifers
 * Aquifers can go deeper and are more likely to connect with cave systems further down.
 * Added more high-frequency variation to aquifers, to reduce the risk of massively huge areas with waterfilled caves everywhere.
 * Underground lakes and flooded regions are more likely to be spread out instead of concentrated in one region.


 * Badlands
 * Tweaked badlands so they sometimes show up in flat areas next to plateaus, and made the red sand generate higher up (to account for the generally higher terrain).
 * Eroded badlands no longer create floating pillars on top of the water surface.


 * Beaches
 * Tweaked beaches a bit, to make them more inclined to show up on flat coastlines rather than hilly areas.
 * Reduced the amount of stone shores.


 * Desert Temples
 * Desert temples spawn on the surface rather than at a fixed y level.


 * Mountains
 * Made peak biomes and meadows less likely to generate in flat low elevation areas.
 * Snowy slopes and snowcapped peaks no longer place dirt under the snow.


 * General
 * Tweaked biome placement to reduce the risk of temperature clashes (such as a snowy biome in the middle of a desert).
 * Temperature clashes still happen, but not as often.
 * Tweaked biome placement to allow for more noisiness and diversity again, essentially dialing back some of the changes from last snapshot.
 * This means microbiomes are more likely to happen again, but they will usually be of matching temperatures (for example a small forest inside a plains biome).
 * Smoothed out the cliffs in shattered terrain a bit, so they don't look like chunk errors.
 * Grass no longer generates under water.
 * Reduced the risk of incorrect surface placement such as grass patches in deserts.
 * Reduced the risk of river biome generating in dry mountain gorges.

Fixes

 * Fixed goat spawning (they weren't spawning in the new mountain biomes)
 * Fixed an issue where players in multiplayer can face far more or far fewer enemies than intended, particularly when other players are flying. Each player now gets their fair share of mobs.

Trivia

 * Unlike 1.18 Experimental Snapshot 1, the title of this version is written in lowercase.

Issues
This version is not supported on the bug tracker, and therefore issues affecting it will be resolved as "Invalid".
