Additions

General

Lighting

• Added dynamic lighting.

  • Due to this, caves have now been made darker.

• Shadows appear below mobs.
• Changed shading on the sides of blocks.

Changes

Blocks

Brown Mushroom

• Changed texture from .

TNT

• Placing a TNT block, and then destroying it, causes the layer below to turn to wood, but only blocks made of the same material get replaced. This was used by Notch to debug flooding.

Mobs

Mob

• TNT was removed from hotbar.
• The player now spawns with 99 stone slabs, stone, water blocks and lava blocks.
  • These changes can only be found by modding as the game runs in Creative by default.

• The player only has one bubble of air bubble when breathing underwater, down from 10.

  • These changes can only be found by modding as the game runs in Creative by default.

• Rain now goes through glass.
• The world is now generated as a small size by default.
• Grass block no longer spreads.
