Java Edition Infdev

Infdev (or Infinite Development) is the third phase in the Development Cycle of Minecraft and is only playable in single player survival mode. Infdev succeeded Indev when a plan for infinite maps was set in place by Notch. Infdev's main new feature was the addition of infinite maps, hence the "inf" in the name.

Infdev works by generating an area of land for the player when they first spawn, then continues to generate more land as the player ventures into unexplored areas. The maps generated by infdev can theoretically be up to eight times larger than the surface of the Earth (though much smaller volume-wise since maps are only about 64 meters deep).

Features

 * Infinite map generation.
 * More craftable items.
 * 3D clouds.
 * Much more complex cave systems.
 * Dynamic fluid system.

Alpha replacing Infdev
Infdev was replaced by Alpha. Infdev no longer gets updated, and its link has been removed from the Minecraft website. As of September 2010, Timmy has removed the Indev and Infdev versions.
