Java Edition Infdev 20100325

A version of Minecraft Infdev was released on March 25, 2010.

Additions

 * Re-implemented caves.
 * Ores now generate in ore blobs.
 * Re-added many particles.
 * Re-implemented block ticks, allowing for crops to grow, fire to spread, grass to spread to dirt, and more.
 * Can no longer place fire on the sides of non-flammable blocks
 * Flowers pop off when not exposed to sunlight
 * Slabs will now make double slabs when possible.
 * Furnaces now work like they did before Infdev.

Bugs

 * The game progressively degrades in performance, becoming unbearably slow within minutes of loading a world. (This is caused by flowers that are generated in places where they break as soon as they appear, resulting in an increase in the number of entities. In rare cases, a flower or chunk will break in such a way to spawn insane amounts of entities, bringing the game to a grinding halt in seconds.)
 * Above-ground cave entrances cut into trees and brick pyramids, resulting in half-destroyed trees and brick pyramids containing caves. The entrances also do not turn dirt into grass, which results in patches of dirt strewn across the terrain near cave entrances.

Fixes

 * Due to the removal of the duplicate login detection, the game no longer randomly crashes with the "session conflict" screen.
