1.7

Minecraft 1.7, The Update that Changed the World, overhauled biome generation, adding dozens of biomes, new tree types, and a reworked fishing system. It was released on October 25, 2013 as one of the game's numbered feature updates.

At its heart, 1.7 is a complete rewrite of how the world is generated. The standout addition is a sweeping biome overhaul with acacia and dark oak forests and many new flowers. Its name reflects that existing worlds generated entirely new terrain at their borders.

This page breaks 1.7 down into 10 headline features, 3 notable gameplay or technical changes and 2 documented fixes, and a plain-language summary of why the update matters. Java Edition is the original PC version of Minecraft, available on Windows, macOS, and Linux.

The most talked-about part of the The Update that Changed the World update is a sweeping biome overhaul with acacia and dark oak forests and many new flowers.

In full, 1.7 adds massive biome overhaul with many new biomes, amplified world type, new flowers (Sunflower, Lilac, Rose Bush, Peony, etc.), Stained Glass and Stained Glass Panes, Packed Ice, podzol block, Red Sand, and new fish types (Salmon, Clownfish, Pufferfish), with several further additions listed on the right. Together these are what make The Update that Changed the World worth updating to, and each appears in the Major Features list on this page.

Beyond new content, 1.7 reworks how parts of the game behave. The notable changes include world generation completely overhauled, new server list with icons, and fishing reworked with treasure and junk categories. Adjustments of this kind reshape day-to-day play for existing worlds as much as new ones.

On the bug-fixing side, 1.7 resolves major performance improvements and fixed numerous world generation bugs. Several of these are performance-focused, so the update can feel smoother even where nothing visible changed.

To play Minecraft 1.7 on Java Edition, open the official Minecraft Launcher, select the Java Edition tab, and use the version dropdown beside the Play button to choose 1.7. As a full release it appears in the standard release list by default.

Before updating an existing world to 1.7, it is good practice to copy the save folder first. Worlds from 1.6 upgrade in place, but newly generated chunks will use 1.7's world generation while older chunks keep their original terrain.
