Java Edition Indev 0.31 20091223-1

The first version of Indev 0.31 was released on December 23, 2009 at 00:40 UTC.

This is the first version of the Indev development cycle of Minecraft, and the first paid version of Minecraft (available at €5.00), as Notch released this version for paid users to test out new features.

Mobs

 * Rana.png Rana
 * Has the player's shadows.
 * All other mobs no longer spawn.

General

 * Lighting
 * Added dynamic lighting.
 * There are 9 different light levels.
 * Due to this, caves have now been made darker.
 * Oddly, 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.

Gameplay

 * Game modes
 * This version, as well as 20091223-2, is in Creative mode.
 * Survival mode can be added back via modding as always, however.
 * Survival mode
 * The player now spawns with 99 stone slabs, stone, water blocks and lava blocks (leftover from an unreleased Indev 0.30 version)
 * TNT was removed from hotbar.
 * Removed Primed TNT, arrows, block drops and all mobs except Rana from the code.
 * Blocks no longer drop items when mined.
 * Attempting to fire arrows will not do anything.
 * No survival build of this version was released, so these changes go unused, and can only be found via modding.


 * Multiplayer


 * Multiplayer was made partially inaccessible (although the multiplayer code still exists and can be re-enabled).
 * Connecting to a multiplayer server will cause players to spawn in a bedrock cube.
 * The game will act as if it is in Singleplayer – chat is inaccessible and the player list cannot be opened.


 * General
 * New work-in-progress level format
 * Level saving/loading no longer works.
 * Dandelion (item) JE1.pngrs in the build screen are now shown with both sprites crossed.
 * The player's fist no longer displays.
 * Rain will now go through glass.
 * The world is now generated as a Small size by default.

Bugs

 * Generating new world in a huge size sometimes causes a lot of Ranas to spawn close to the player, resulting in the game freezing for some time.
 * Placing a block on a slab causes the space between to be completely dark.
 * The top of the map is completely dark.
 * Block breaking particles are pitch black.
 * Placing a TNT block, and then destroying it, will cause the layer below to turn to wood, but only blocks made of the same material get replaced.
 * This was intentional and was used by Notch to debug flooding.
