0.0.12a (22 h 36 min, 19 mai 2009 ans – 22 h 44 min, 19 mai 2009 ans)

Description:

0.0.12a was a version of Classic released on May 19, 2009, at 22:36 UTC. It added bedrock, water and lava, along with a world boundary and a new world generator.

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, it's texture from 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.
