Java Edition Infdev 20100617-2

A version of Minecraft Infdev was released on June 17, 2010.

General

 * Getting stuck inside blocks now causes suffocation.
 * The player's hand can now be seen.

Blocks

 * Flowing water that touches flowing lava creates cobblestone.
 * Flowing water that touches standing lava turns the lava into obsidian.

World generation

 * Improved caves.
 * Caves are even more regional, with truly swiss cheese areas being possible but rare.
 * Springs, both water and lava, are more common.
 * Increased variety in tunnel thickness, increasing the odds of branches.
 * Added natural gravel and dirt under ground for more varied caves.
 * Surface springs.

Blocks

 * Lava now only spreads 4 blocks instead of 8.
 * Layer 0 can now have blocks placed in it.

World generation

 * Ores:
 * Prior to this version, all ores were generated with a random amount of veins regardless to the type of ore.
 * Lava springs don't spread.
 * Water flows nicer.
 * Made massive tweaks to the pending tile tick logic (used for liquids and fire), quite possibly fixing a crash bug.
 * The bottom layer is no longer lava, instead filled partially with bedrock including stone gaps.
 * Removed the infinite lava sea from under the world (removed when updating, replaces layer 0 with The Void)

Fixes

 * Fixed a few bugs in liquid spreading code.
 * Fixed invisible waterfalls.
