Minecraft:Java Edition guides/The Update that Changed the World

This guide is a simplified overview of all the changes in Minecraft:The Update that Changed the World (Template:JE 1.7.x releases), which assumes at least some familiarity with the Minecraft:Horse Update (Java Edition 1.6.x releases).

Mobs

New

Minecraft:Chicken jockey

Template:Animate

Zombie and zombie villager jockey spawn in Overworld, zombie pigman jockey spawns in Minecraft:the Nether.

Chickens drop: 0–2 Template:ItemLink 1 Template:ItemLink, when not killed by fire. 1 Template:ItemLink, when killed while on fire. Template:Xp if killed by a Minecraft:player or tamed Minecraft:wolf. Baby zombies drop: 0–2 Template:ItemLink, and rarely Template:ItemLinks, Template:ItemLinkes and Template:ItemLinks. Template:Xp, plus Template:Xp per equipment piece (when killed by a Minecraft:player or tamed Minecraft:wolf) Baby zombies also have a 8.5% chance each of dropping their Template:ItemLink Template:ItemLink or any equipped Minecraft:armor that they spawned with. The chance of each can be increased by 1% per level of Minecraft:Looting, up to 11.5% chance. The equipment is usually badly damaged, and may be Minecraft:enchanted. If killed by a Minecraft:charged creeper, it drops a Template:BlockLink.

Biomes

New

Biome variants/technical biomes		Over 20 variants for new and existing biomes. M – Biomes with an M variant are rarer than the normal version of that biome and contain some specific modification, such as taller trees or more water pools. Plateau – Biomes with a plateau variant are like the hills technical biome, but flattened at the top. Mesa (Bryce) – A rare variant of the mesa biome that works similar to ice spikes, with tall clay spikes generating from the sandy mesa floor. Hills – More technical hills biomes have been added to fit with the new biomes. Stone Beach – Generates between mountains and oceans to create rocky cliffs.
Minecraft:Mesa	File:Badlands.png	Contains mountains composed of multiple types of colored Minecraft:hardened clay that are layered in a way that resembles sedimentary rock. There are seven colors including normal, orange, red, yellow, white, light gray and brown. The flat lands below the mountains are similar to a desert biome, but made of Minecraft:red sand instead of sand. Minecraft:Dead bushes and Minecraft:cacti spawn in this biome. Occasional dying forests spawn on top of the clay mountains.	Minecraft:Oak trees (in some variants)

Minecraft:Giant mushrooms Minecraft:Dark oak trees Minecraft:Oak trees Minecraft:Birch trees
Minecraft:Birch forest	File:Birch Forest.png	A forest made entirely of birch trees. Has a variant with taller birch trees that cannot be grown from saplings.	Minecraft:Birch trees

Minecraft:Mega taiga	File:Mega Taiga Hills.png	A forest of giant 2×2 Minecraft:spruce trees, which tower above the regular spruce trees that grow between them.

Changed

• Each biome now has a "temperature" value. Biomes with similar temperature values are more likely to generate next to each other.
• Biomes can be divided roughly into 4 categories based on how their temperature affects precipitation:
  • In hot biomes, it never rains.
  • In warm biomes, it rains at all altitudes.
  • In cool biomes, it rains at low altitudes and snows at high altitudes.
  • In snowy biomes, it snows at all altitudes.
• Many existing biomes have been updated, and some have received slightly different variants where some key aspect of the generation is different:

Minecraft:Desert	File:Desert Lakes.png	Added desert lakes, a desert variant containing water lakes. Similar to pre-1.6 deserts.	Minecraft:Desert wells Minecraft:Desert pyramids Minecraft:Villages
Minecraft:Jungle	File:Jungle.png	New variants include modified jungle, jungle edge, and modified jungle edge. Melons now generate in jungles.	Minecraft:Jungle temples Minecraft:Jungle trees Minecraft:Oak trees

New variants include wooded mountains and gravel mountains. Stone cliffs now generate between mountains and oceans.	Minecraft:Oak trees Minecraft:Spruce trees
Minecraft:Snowy taiga	File:Snowy Taiga Mountains.png	Renamed from "Taiga" to "Snowy Taiga". Added mountainous variant.	Minecraft:Spruce trees

World types

New

Minecraft:Amplified

File:AmplifiedWorldMojang.jpg

It scales up all world generation rules, so it uses the entire world height. Almost all biomes can generate huge mountains that can reach well above Y=200. Extreme hills biomes frequently reach the world height limit at Y=256. Swampland and ocean biomes are unaffected by this world type. Extremely resource intensive and requires powerful computer to run. Ravines here can reach down to bedrock. Contains numerous various landforms that are very rare or non-existent in default generation. Some examples include floating islands, overhangs, large water and lava falls and huge indents. Taiga biomes reach such altitudes that snow starts generating (about Y=130).
