The first version of Indev 0.31 was released on December 23, 2009 at 00:40 UTC.^[1][2]

This is the first version of the Indev development cycle of Minecraft, and the first paid version of Minecraft (available at €9.95), as Notch released this version for paid users to test out new features.^[1]

Lighting

• Added dynamic lighting.
• There are 9 different light levels.
  • Due to this, caves have now been made darker.
• Blocks in the inventory and hotbar are affected by lighting – upon generating a new world they appear dark, then go back to normal brightness after a while.
• Shadows appear below mobs.
• Changed shading on the sides of blocks.

Bedrock

• Added to the bottom layer of the world again.
• Hardness is now equal to 999.

Brown mushroom

• Changed model from .
• Inventory sprite changed from to .

Dandelion

• Changed model from .
• Inventory sprite changed from to .

Lava

• Inventory sprite changed from to (the geometry is now subtly different).

Red mushroom

• Changed model from .
• Inventory sprite changed from to .

Rose

• Changed model from .
• Inventory sprite changed from to .

Sapling

• Changed model from .
• Inventory sprite changed from to .

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.^[3] This was used by Notch to debug flooding.^[4]

Water

• Changed model from .
• Inventory sprite changed from to (the geometry is now subtly different).
• The side faces now have a separate, dedicated "flowing" texture.

Mob

• Uses a new model and texture, known as "Rana".
• Can now spawn again.

Game modes

• This version is in Creative mode by default.

Survival mode

• These changes can only be found by modding, as the game runs in Creative mode by default.
  • As a side effect of the entity removal, blocks no longer drop items when broken and attempting to fire arrows does not do anything.
  • The player only has one air bubble when breathing underwater, down from 10.
  • TNT was removed from the hotbar.
  • The player now spawns with 99 stone slabs, stone, water blocks and lava blocks.

• The item forms of blocks are now lit differently and have been rotated such that the top texture now faces the opposite direction. The left and right sides of blocks are now lit the same. If a block used a solid white texture, the top would remain white, whereas the other two sides would be the same shade of grey:
   #828282
• The inventory sprites for water (still and flowing), lava (still and flowing), saplings, dandelions, roses, and red and brown mushrooms also changed in this version, but are excluded from the following table as they had other visual changes beyond just shading.
