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.

Additions

1.7.2 block and item additions

Blocks

Stained glass Stained glass panes

• 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.
• 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 ignore each other's colors, and render only 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.

World generation

  • Jungle biomes have been made much rarer.
  • Has a jungle edge which has less foliage, but slowly leads into the main jungle.
  • Jungle trees now generate with branches.

  • The extreme hills edge variant no longer generates.
• Taiga
  • Now generates without snow.
  • Snowy taigas have been implemented as a separate, new biome called "cold taiga".
• Ocean
  • Oceans are smaller and take up much less of the map.
  • Contains only gravel on the floor instead of sand, dirt and gravel.
  • The frozen ocean variant no longer generates.
• River
  • Gravel can now generate in disks.

Biome categorization

• Four main categories based on temperature:

• Biomes avoid getting placed next to a biome that is too different to itself.

Biome elevation

• Much greater variation of elevation in general.
• Most biomes can generate to Y=100.
• Hills technical biomes have been made taller.

Temperature

• Each biome has a base temperature that determines whether the biome is snow-covered, whether it rains or snows, or whether it rains at all.
• Biomes are grouped according to their temperature and attempt to generate next to biomes with similar temperatures.
• Temperature decreases by 0.05 every 30 blocks increase in altitude.

Caverns

• Are less dense and interconnected.

Witch huts

• Now generate with a witch inside.
  • They formerly generated empty, with witches spawning inside later.

Bonus chests

• Can now contain acacia logs.

World boundary

• All blocks beyond X/Z 30 million (±30,000,000) from origin now act as solid blocks.
  • This includes air blocks.
  • This creates essentially an invisible wall at the boundary.
  • This boundary and blocks beyond it cannot be selected, and are unbreakable by any means.
  • Despite functioning like a solid block, it cannot be placed using the /setblock command, and does not exist in an item form, unlike other blocks.
  • As all blocks function as solid, if the player is moved outside the boundary via external tools, they are unable to move outside the block space they are within.
    • Despite that, the camera can still move normally.
  • Ghost chunks still generate.
  • Spiders can climb this boundary, since all blocks function as solid.

Gameplay

Fishing

• Items other than fish can be obtained by fishing.
  • These are divided into three classes.
    • Fish: raw fish, raw salmon, clownfish and pufferfish.
    • Treasure: enchanted fishing rods, enchanted bow, enchanted books, name tags, tripwire hook, lily pads and saddles.
    • Junk: damaged fishing rods, water bottles, rotten flesh, string, leather, bowls, sticks, bones, tripwire hooks, ten stacked ink sacs and damaged leather boots.

  • Armor, bows, fishing rods & swords can receive the enchantment directly without the use of enchanted books.
• New enchantments for fishing rods that can bias the outcome of fishing.
  • Lure – reduces wait time to catch an item; increases the chance of catching fish and decreases the chance of junk and treasure.
  • Luck of the Sea – increases chance of getting treasure and decreases chance of getting junk.
• Enchanted books can receive multiple enchantments at once.

Nether portal

• Can now have different width and height, to allow for design variations.
  • If the one in the Nether is big enough, ghasts can go through them.
• Portals can be activated when any fire block appears inside the frame.
  • Before only the bottom-most blocks would work.
• New nether portal building rules: Any rectangular size from 4×5 to 23×23.

Fog

• Fog now covers 25% of the view distance instead of 75%.

Death screen

• If the player dies and selects the 'Title screen' button, a prompt asks if they are sure they want to quit, and give the player the options to go to the title screen or respawn and continue playing.

Command format

Scoreboard
