    NEW FEATURES IN 21W06A

    • Added noise caves and aquifers

    NOISE CAVES AND AQUIFERS
    Noise caves are a new way of generating caves, providing more natural variety. They can get really huge sometimes!
    Noise caves come in two flavors:

    • Cheese caves. Like the holes in swiss cheese. These often form caverns of various sizes.
    • Spaghetti caves. Long squiggly tunnels, sometimes wide like tagliatelle.

    WORLD GENERATION

    • Generation range and build limits have been expanded by 64 blocks up and 64 blocks down, to a total range of 384 blocks.
      Underground features, structures, and caves generate all the way down to y -64.

    I've got a server for some friends that we've been playing on since Alpha. Same world, just bloated and busted as updates have happened. We can't bring ourselves to move on from it, no matter how ugly and massive it is.

    I'm curious to see how old worlds are handled with this update. Will old areas suddenly have more underground? or will only new chunks have the deeper depth?

    edit: Oh just finished the video and he says that currently there's no upgrade path, but we may see one before final release.

      They'll definitely have one. They always do. Minecraft has code that runs on new chunks after an update to apply fixes, so they'll come up with safe borders or something.

      Worlds have been preserved since early early alpha builds, and worlds have gone through multiple format changes since then. No promises it'll be pretty, of course. But it'll work.

      edit: Here's some info from a dev.

      The new extended underground isn't done, this is just the first snapshot for it and we got a bunch of things to fix and tweak. And your feedback and bug reports will help guide us! Also, in this snapshot old worlds won't load/convert. But don't worry, they will later :)

      Considering that the world height was expanded into the negative instead of just shifting everything 64 blocks upwards I'll claim that the way the upgrade will work is that old chunk will keep their Y=0 Bedrock layer while new chunks will be generated according to the new world generation.

      I'm curious however how the interaction between old and new chunks will play out. Will we be able to fly under the bedrock of old chunks by digging down and over from new chunks?

      Also curious which effects this will have on the Nether. Will the bedrock layer also be lowered or stay the same like when the build height was doubled in 1.2.

        Considering this is so obvious it was both our first thoughts, I'd expect the devs to think of that. The easiest way is to just pad old chunks with more bedrock on the bottom... Or you could...

        Considering this is so obvious it was both our first thoughts, I'd expect the devs to think of that. The easiest way is to just pad old chunks with more bedrock on the bottom... Or you could generate normal terrain below, which would only be reachable via newly generated areas.

          This line kinda ruins all your ideas, it's in the news post someone linked to here.

          You'll be unable to open old worlds in this snapshot as there is currently no upgrade path towards the new world height
