Java Edition 1.7.2

1.7.2, the first release of The Update that Changed the World, is a major update to Minecraft released on October 25, 2013, which added many new biomes, new generated structures, new flowers, stained glass, better networking, new commands and more.

A pre-release for 1.7.2 was released earlier on October 25, 2013, though the full release of 1.7.2 is identical to this pre-release.

Blocks

 * Stained glass

 * Doing this yields 16 stained glass panes, like normal glass.
 * Water, nether portals and other stained glass blocks remain visible when looked at through a stained glass block.
 * Looking through a solid wall of glass blocks, is equivalent to looking through a single piece (this does not apply to glass panes of any kind).
 * Air blocks make the view blurrier each time.
 * Adjacent glass of different colors will ignore each other's colors, and will only render the terrain behind, with the color of the outermost piece of glass.
 * Other translucent blocks may have different effects.
