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 3 (known as 1_18_experimental-snapshot-3 in the launcher) is the third experimental snapshot for Java Edition 1.18, released on August 10, 2021,[2][3] which makes numerous changes to world generation and fixes bugs from previous experimental snapshots.
Additions
[edit | edit source]World generation
[edit | edit source]
- A new mountains biome that is a variant of lofty/snowcapped peaks that uses stone and strips of gravel, instead of snow and ice.
- Is used to avoid temperature clashes.
Changes
[edit | edit source]Mobs
[edit | edit source]General
- Mob spawning is now consistent throughout all altitudes increasing spawn rates in higher altitudes and decreasing spawn rates in lower altitudes.
- The spawning rates are similar to 1.17's spawning rate at Y=64.
World generation
[edit | edit source]- 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.
- 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.
- Tweaked biome placement to reduce the chance of temperature clashes.
- Tweaked biome placement to allow for more noisiness and diversity.
- This allows for the reintroduction of microbiomes.
- 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 spawn on the surface rather than at a fixed y-level.
- 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.
- Now generate in all the new mountain biomes.
- Swamps are less likely to overlap cold or dry biomes, and they no longer place hanging water.
- Now generate in meadows.
General
- Smoothed out the cliffs in shattered terrain a bit.
- Coastlines and river banks are less likely to be intersected by aquifers.
- Local water levels are mostly used in terrain that doesn't border a river or ocean.
- Cave openings and ravines that intersect an ocean or river mostly use sea level.
- Inland low-elevation areas are less likely to have flooded caves everywhere.
- Grass no longer generates underwater.
- Reduced the chance of incorrect surface placement.
- Reduced the chance of river biome generating in dry mountain gorges.
Fixes
[edit | edit source]- Fixed goats not 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.
- MC-30560 was fixed by this version, although it was not marked as such due to the bug tracker not handling experimental snapshots.
Issues
[edit | edit source]This version is not supported on the bug tracker, and therefore issues affecting it will be resolved as "Invalid".[4]
