This page covers a development version that has a major issue under certain conditions.
The dedicated server for this version has a security vulnerability in the Log4j library that could be used to perform a remote code execution exploit. It can be addressed by appending a certain JVM argument to the server startup command line.[1]

1.18 Experimental Snapshot 4 (known as 1_18_experimental-snapshot-4 in the launcher) is the fourth experimental snapshot for Java Edition 1.18, released on August 17, 2021,[2][3] which makes numerous changes and tweaks to world generation.
Changes
World generation
General
- Tweaked biome placement in general to reduce the risk of harsh collisions.
- Now biome placement is a bit smoother and less noisy. This should result in fewer microbiomes.
- Removed surface freezing for hot biomes, and raised the altitude at which snow layers are placed.
- Now is larger and less likely to show up as microbiome splotches.
- Terracotta bands now go higher.
- Their grass and trees now start higher.
- Now is larger and less likely to show up as microbiome splotches.
- Desert pyramids now tend to be partially buried and no longer generate on water.
- The terrain is now more extreme. Fiddled with the placement of shattered terrain and extreme hills in general to make it fit in with the terrain better.
- No longer generates on water.
Ore distribution
- Reduced the number of diorite/andesite/granite blobs on the surface.
- Copper ore blobs now are bigger in dripstone caves.
- More iron is generated.
- Reduced the likelihood of rivers being cut off and turning into steep dry river gorges in mountainous terrain.
- Rivers tend to either carve a fjord through the mountain range, or raise the terrain to form a saddle valley between the peaks.
- Now have fewer dirt blocks.
- Tweaked swamp placement a bit.
- Are less likely to extend far out from the coastline.
- Rivers in swamps now tend to be shallower.
