Changes

Blocks

Minecraft:Stone

• Water next to lava produces stone.

Mobs

Mobs

• No longer get reset on level reset, meaning there is no way to get rid of mobs now.<ref>Template:Link</ref>

Non-mob entities

Minecraft:Player

• Player jump height increased by about 0.5 blocks.<ref>Template:Ytl</ref>

World generation

General

• An infinite ocean now surrounds the map, making it impossible to fall off the world.
• The player can no longer pass the edge of the map.
• Terrain is messier with more bumps visible on the surface. It also now generates in islands.
  • The terrain always generates one block above ocean level.
  • Lakes occur when the surrounding water is at a higher level than the terrain.
  • All Minecraft:dirt with access to sunlight doesn't become grass blocks upon world generation if below water level.
• Minecraft:Lava lakes also spawn occasionally.
• Worlds made before this version receive a bedrock layer at the bottom of the map and an Minecraft:ocean surrounding it.

Trivia

• The video released by Notch on May 18th showing off 0.0.12a is actually a developer variant that was never released to the public. See Development for more information on this.
• To make the water and lava texture display slightly shorter than a block, its texture from Minecraft:terrain.png gets shifted down a bit in-game. This causes the texture to overlap with the block below at some angles.
• The 0.0.13a-launcher jar contains the level generation files for this same version, which is also the same terrain generation files used in the full, public release of it (and 0.0.12a_01-03). It has variables that can enable and disable the uniform dirt layer, and it has been disabled for the public variant of 0.0.12a (or at least 0.0.12a_03 for certain). It also has variables for the water filling up the world from the corners, which can be disabled.
