Minecraft wiki entry for Unused_textures, associated text: The texture was eventually removed from Java Edition in 13w02a and Pocket Edition in v0.8.0 alpha build 2 due to the deprecation of terrain.png in those versions. It was removed from Xbox 360 Edition in TU12 due to being replaced by the vertical dispenser texture, although it still technically persists in the base game as the original terrain.png was never removed, despite never being used in TU3 onwards.
