Java Edition 1.7.2

1.7.2, the first release of The Update that Changed the World, was a major update to Minecraft (Java Edition), which added many new biomes, new generated structures, new flowers, stained glass, better networking, new commands and more.

Blocks

 * Stained glass
 * Glass can be dyed into all 16 colors.
 * This is done by putting a colored dye in the center of a crafting table and surrounding it with 8 pieces of normal glass, yielding 8 stained glass.
 * Stained glass can be crafted into stained glass panes using the same recipe as normal glass panes.
 * Doing this yields 16 stained glass planes, 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.
 * Has ID number 95, which replaces the Locked Chest's data value.


 * Wood Varieties
 * Acacia wood
 * Silver outside with orange inside.
