This page covers a release version that has a critical issue under certain conditions.

The dedicated server for this version includes a security vulnerability in the Log4j library that could be used to perform a remote code execution exploit. It can be addressed by appending a certain JVM argument to the server startup command line.^[1]

Other editions with a version "1.7.2":

There is a guide for this update!

See Java Edition guides/The Update that Changed the World for a guide to all of the new features introduced in The Update that Changed the World.

1.7.2, the first release of The Update that Changed the World,^[2] is a major update to Java Edition released on October 25, 2013, which added many new biomes, new generated structures, new flowers, stained glass, better networking, new commands and more.^[3]

A pre-release for 1.7.2^[3] 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.

Biome categorization

Four main categories based on temperature:
- Snow-covered, cold, medium and dry/warm.
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.

- 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

- Added 744 new objective criteria that were previously tracked only through statistics and achievements.

Commands

/time set day

- Syntax examples:
  - /give @p 1 1 0 {display:{Lore:["Hi,","How are you?"],Name:"Nice Stone Block"},ench:[{id:1,lvl:10}]}
  - /summon Pig ~ ~ ~ {Saddle:1,CustomName:"Babe",CustomNameVisible:1}
  - /setblock ~ ~ ~ 397 3 replace {SkullOwner:MHF_Pig}
- This removes the need to use external tools.
/give
- Prints renamed items' name by default in chat. The chat shows the corresponding tooltips when hovered over.

NBT format

Unbreakable tag.
- Applies to items with durability.
- Nullifies any usage dealt to the item.
List tags no longer need to be named.
No longer crashes when given the wrong type (integer/short).
Added <structure>.dat files in data folder for storing structure data.
- Contains .dat called Village.dat, Fortress.dat (Nether Fortress), Temple.dat (Desert temple, jungle temple and witch hut), Stronghold.dat, Mineshaft.dat and others.
- NBT structure consists of the individual parts of each structure, labeled "children", the chunk it originates in, a tag called BB, and an ID for what type of structure it is.
  - The children tags have information on each part of the structure and the type of part it is.

Block/Item IDs

Can be referred to by their names, instead of numbers in commands.
- Named references are planned to be be the only option in the future.
- Necessary for the Plugin API.

General

Block and entity bounding boxes are now completely black instead of dark gray.

Sounds

Sounds and music are stored together in the new .minecraft/assets/sounds folder.
Music now pauses when pausing the game.

Lighting

Several lighting issues fixed.
A lot fewer "black spots" in terrain generation.
- Some black spots occurrences have to be kept, in order to avoid a bug in world generation, associated with a complete removal of them.
Torch bugs in strongholds and mineshafts have been fixed.
The light level actually falls to 7 during thunderstorms.
- Before it stayed at 12 like normal rain, but hostile mobs could spawn as if the light level was 7.
