Java Edition 13w38b

13w38b is the sixth snapshot for Java Edition 1.7.2, which was released to fix some of the bugs and crashes in the 13w38a snapshot.

General

 * Options
 * Super Secret Settings
 * Added bumpy shader.

Blocks

 * Air
 * Redefined the concept of air.
 * Is now an actual block instead of the absence of a block (null).
 * It can be kept in the inventory.
 * It looks like a magenta and black checker pattern (the missing texture) in the inventory, when dropped, and when put into an item frame. But when held in the player's hand, it looks invisible, like an actual air block.
 * Drops from villagers.

World generation

 * Swampland
 * Removed marsh-like areas (later readded in ).

Trivia

 * 13w38b was previously removed from the launcher for some time, but was added back in September 2018.
