• 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.
• 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.

• 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.

Word of Notch post

• 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.
