Java Edition Infdev 20100325

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

Additions

 * Re-implemented caves.
 * Re-implemented block ticks, allowing for crops to grow, fire to spread, and grass to spread to dirt.

Bugs

 * The game progressively degrades in performance, becoming unbearably slow within minutes of loading a world.
 * 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

 * The game no longer randomly crashes with the "session conflict" screen.
