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]

πŸ‘ Image
Stony Peaks

  • 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]

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

  • 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.

Biomes

  • 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.

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.

Pillager outposts

  • Now generate in all the new mountain biomes.

Swamps

  • Swamps are less likely to overlap cold or dry biomes, and they no longer place hanging water.

Villages

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]
