OK we’re back from vacation and we’ve made a new experimental snapshot with a bunch of tweaks. Try it out (ideally in survival) and give us feedback!
This update can also be found on minecraft.net. See also snapshot 1 and snapshot 2.
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).
Red sand is back! 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).
Made peak biomes and meadows less likely to generate in flat low elevation areas.
Smoothed out the cliffs in shattered terrain a bit, so they don’t look like chunk errors.
Snowy slopes and snowcapped peaks no longer place dirt under the snow. Mountains look less dirty now 🙂
Added a new mountain biome: Stony peaks. This is just a variant of lofty/snowcapped peaks that uses stone and gravel instead of snow and ice, and is used to avoid temperature clashes such as a snowcapped peak sticking up from a jungle.
Added structures to some of the new mountain biomes. Pillager outposts generate in all the new mountain biomes. Villages generate in meadows.
Tweaked beaches a bit, to make them more inclined to show up on flat coastlines rather than hilly areas. Also reduced the amount of stone shores.
Coastlines and river banks are less likely to get messed up by aquifers. That is, 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 will mostly use sea level.
Inland low-elevation areas are less likely to have flooded caves all over the place.
Aquifers can go deeper and are more likely to connect with cave systems further down. That means if you dive into a deep lake on the surface (or in a mountain), you will sometimes encounter air pockets that lead to a cave system.
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.
Fixed goat spawning (they weren’t spawning in the new mountain biomes)
Swamps are less likely to overlap cold or dry biomes, and they no longer place hanging water. Swamps are even happier now.
Desert temples spawn on the surface rather than at a fixed y level.
Eroded badlands no longer create floating pillars on top of the water surface.
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. We don’t have support for actual rivers generating above sea level, so if a mountain gorge is above sea level then it will be dry.
Mob spawning no longer speeds up in low terrain or slows down in high terrain. The new spawning speed is similar to 1.17 spawning at y=64. This change is intended to make spawning more consistent in the updated overworld.
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.
NOTE: These snapshots are experimental! Some features may be significantly changed or even removed if needed to improve performance.
Low performance (we are working on performance optimization for the normal snapshots coming later)
Nether terrain is messed up
End pillars don’t generate (however they do generate when you respawn the dragon…)

Download this zip file
Unpack the folder into your “versions” folder of your local Minecraft application data folder (see below if you are confused)
Create a new launch configuration in the launcher and select “pending 1.18_experimental-snapshot-3”
Start the game and the remaining files will be downloaded
Play in a new world! Note: This version is not compatible with other snapshots.
Finding the Minecraft application data folder
Windows: Press Win+R and type %appdata%.minecraft and press Ok
Mac OS X: In Finder, in the Go menu, select “Go to Folder” and enter ~/Library/Application Support/minecraft
Linux: ~/.minecraft or /home//.minecraft/

We are mostly interested in feedback about the new world generation overall, and what it is like to play in it. We are also looking for feedback on the updated mob spawning. We changed so that mobs only spawn in complete darkness in order to make it easier to spawn-proof the new larger caves.
New feature requests are not so useful at this point, since the scope of the Caves & Cliffs update is already large enough and we want to focus on finishing the features that we’ve already announced.
Note that we don’t use the bug tracker for experimental snapshots. If you find any new important bugs you can post them here.
What about the previous Caves & Cliffs preview datapack? Can I open old worlds in this experimental snapshot? What about Bedrock? When will these features show up in normal snapshots?
These questions are answered in the original post for the first experimental snapshot
