Water test (May 18, 2009)
[edit | edit source]This section documents an unreleased version.
While there is proof of this version's existence, it was never released to the public.

Word of Notch post, YouTube video (reupload)
- Additions
- Bedrock
- Unobtainable to the player.
- Cannot be broken, placed against or otherwise selected.
- Surrounds the map on all four sides two blocks below ocean level, and also the bottom of the world.
- Water
- It was originally opaque, rendered as a full block and on the same layer as all other blocks (meaning it had shadows).
- The player can swim in it, but mobs move under it at full speed. Swimming underwater was fast at first, as seen in the video.
- Spreads from the world border on world generation to fill any empty space next to it.
- World border
- An infinite ocean and invisible barrier now surrounds the map, making it impossible to fall off the world.
- Pressing F now cycles between four levels of render distance.
- Pressing N generates a new level, but without a level generation screen.[verify for Java Edition] Mobs also don't spawn on level reset.
- Bedrock
- Changes
- New terrain generator
- Terrain is more messy, with more bumps visible on the surface.
- Terrain now generates in islands.
- No blocks can generate on ocean level, the terrain is always one block above it.
- Dirt with access to sunlight will not become grass block upon world generation if below ocean level.
- New terrain generator
Trivia
[edit | edit source]- Water was made transparent before the release of 0.0.12a. To do this, Notch had to make it render on a new layer, which is why it lost its shadows. Water would stay without shadows until the release of 0.0.14a_08.
Lava test (May 19, 2009)
[edit | edit source]This section documents an unreleased version.
While there is proof of this version's existence, it was never released to the public.

- Lava
- Translucent.
- Added shortly before the full release of 0.0.12a, as the screenshot of it posted on Notch's blog is from May 19th, 2009 at 21:09 UTC (an hour and a half before the version was released).
- Water
- Is now translucent and no longer renders as a full block.
- Now generates within the world instead of spreading from the world border upon the world's creation.
