1.21.5

Minecraft 1.21.5 filled in the ground cover of the overworld: nine new plant blocks, brown and blue chicken eggs, and the first of the test blocks for map makers. It was released on March 25, 2025 as a follow-up to the release before it.

At its heart, 1.21.5 is a spring drop that filled the overworld's empty ground with plants. The standout addition is bush, Firefly Bush, Wildflowers, Leaf Litter and the dry grasses. The first game drop after the Winter Drop, built out of the 25w02a to 25w10a snapshots.

This page breaks 1.21.5 down into 3 headline features, 1 notable gameplay or technical change, 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 Spring to Life update is bush, Firefly Bush, Wildflowers, Leaf Litter and the dry grasses.

In full, 1.21.5 adds bush, Firefly Bush, Wildflowers, Leaf Litter, Cactus Flower and the short and tall dry grasses, Blue Egg and Brown Egg, laid by the new chicken variants, and Test Block and Test Instance Block for automated map testing. Together these are what make Spring to Life worth updating to, and each appears in the Major Features list on this page.

Beyond new content, 1.21.5 reworks how parts of the game behave. The notable changes include protocol 770, data pack 71, resource pack 55. Changes like these are typical of a point release, which refines an existing update rather than replacing it.

To play Minecraft 1.21.5 on Java Edition, open the official Minecraft Launcher, select the Java Edition tab, and use the version dropdown beside the Play button to choose 1.21.5. As a point release it sits in the release list alongside the other stable builds.

Before updating an existing world to 1.21.5, it is good practice to copy the save folder first. Worlds from 1.21.4 upgrade in place, but newly generated chunks will use 1.21.5's world generation while older chunks keep their original terrain.
