Classic 0.0.12a (22 h 36 m, 19 maio 2009 ano – 22 h 46 m, 19 maio 2009 ano)
Descrição:
 Bedrock
    Unobtainable to the player.
    Initially referred as "unbreakable stone".
    Bedrock and the layer above (if at the bottom 
    of the world) is always dark even if exposed 
    to the sky.
    Cannot be broken, placed against or 
    otherwise selected.
Water
    A type of liquid.
    Does not drown the player.
Lava
   A type of liquid.
   Does not deal damage to the player.
Border
   An infinite ocean now surrounds the map.
   The player can no longer pass the edge of the 
   map.
Controls
    Pressing F cycles between four levels of 
    render distance.
    Pressing N generates a new level.
Swimming
    Only applies to players. Humans move at full 
    speed in water.
Humans
    No longer get reset on level reset, meaning 
    there is no way to get rid of mobs now
Physics
    Water and lava now flow to fill any available 
    space below or next to it.
        With just one water source the entire world 
         will be flooded.
    Water next to lava produces stone.
New Level Generator
    Terrain is more messy with more bumps 
    visible on the surface.
    Lakes occur when the surrounding water is at 
    a higher level than the terrain.
    All dirt with access to sunlight will not 
    become grass upon world generation if 
    below water level.
    Lava lakes also spawn occasionally.
    Surface dirt layer is more uniform.
    There is almost always a layer of grass with 
    dirt under it above stone.
    Cliff faces can no longer be made of pure dirt 
    and grass.
    Worlds made before this version will receive 
    a bedrock layer at the bottom of the map and 
    an ocean surrounding it.
