Java Edition Infdev 20100330-1

A version of Minecraft Infdev was released on March 30, 2010, at 12:03 UTC.

Additions

 * Level format
 * tag
 * Set to 1 if the chunk is populated (trees and ores have been generated)
 * Chunks generated during inf-2010327 do not have this tag, so they will generate new trees and ores.
 * This fixes the bug causing trees and ores to regenerate under the right conditions.

Changes

 * Smelting time increased back to 8 seconds per item from 4.

Fixes

 * 5 bugs fixed
 * Fixed a bug which caused the contents of containers (i.e. chests and furnaces) to sometimes not be saved.
 * Fixed the broken lighting on slabs.
 * The top of the world is no longer fully lit, and it no longer causes crashes.
 * Fixed a bug that caused trees and ores to regenerate if the world was reloaded.
 * Blocks no longer keep their data value when being broken, which was resulted in newly-planted crops to take on the bock data (and therefore growth stage) of block previously occupying that space.
