Java Edition 1.18 experimental snapshot 5

1.18 experimental snapshot 5 is the fifth experimental snapshot for Java Edition 1.18, released on August 25, 2021, which makes numerous changes and tweaks to world generation.

Mobs

 * General
 * Removed the height-based spawning change that was made in snapshot 3.

World generation

 * Badlands
 * Slightly decreased the size of Badlands.


 * Caves

Carvers can now replace red sand and calcite during world generation.


 * Dripstone Caves
 * In world generation, grass is replaced with stone (if generated near grass).


 * Jungle Edge
 * Re-added the Jungle Edge biome.


 * Lush Caves
 * Now generate with springs.


 * Mountains
 * Mountain tops are now more jagged and pointy.
 * Mountain areas and peak biomes now are slightly larger on average.
 * Raised the average mountain height


 * Mushroom Fields
 * Tweaked mushroom fields biome, now it matches the shape of the islands better.


 * Rivers
 * Tweaked the depth of rivers and the steepness of river banks.
 * They are less likely to be super deep or get cut off in flat areas.
 * Rivers integrate better with swamps, the river tends to get shallow and merge with the swamp instead of carving through.


 * Swamps
 * Moved swamps slightly more inland.
 * Swamp trees can grow in slightly deeper water than before, populating deeper marshes.


 * General
 * Small lakes features are no longer placed in dry and hot biomes (desert, savanna, badlands).
 * Reduced the number of lake feature placements in other biomes.
 * Water springs can generate in more types of blocks such as dirt and snow, increasing the likelihood of small mountain streams and waterfalls.
 * Reduced the amount of shattered terrain and shattered savanna biome, replacing some of that space with flatter beaches instead.



Fixes

 * Fossils with diamonds no longer generate above deepslate level.
 * Fixed an unintentional change from snapshot 4 that made mountains lower and smoother.
 * Small hills and overhangs (3D noise) generate more often in flat areas, like in the third experimental snapshot.
 * Fixed an indent in the code.
