Minecraft 1.21.4-pre2 Update - What's New
Second pre-release for 1.21.4 with Creaking behavior adjustments and pale garden generation fixes.
Overview
Minecraft 1.21.4-pre2 is a pre-release for Minecraft: Java Edition, published on November 22, 2024. Pre-releases are feature-complete candidates handed out near the end of a version's development so plugin authors and server owners can test against a near-final build. This one carries 4 logged changes, mostly final-stretch fixes.
The work in this update spans bug fixes. On the bug fixes side it brings Adjusted Creaking detection angle thresholds and pale hanging moss placement rules. It also resolves 4 reported bugs, which is typical maintenance work that keeps worlds and servers stable.
This build is part of the development cycle leading to 1.21.4. Treat it as a preview rather than a destination: features can change, be renamed, or be cut entirely before they reach the stable release, so it is meant for testing and feedback, not for your main world or a live server.

What This Means
For players
As a pre-release, 1.21.4-pre2 is close to final but still a test build. It is a good way to preview 1.21.4 early, but keep your main world on the current stable version until the full release lands.
For server admins
Do not run 1.21.4-pre2 on a public server. Development builds like this exist so you can test plugins and mods ahead of launch, not to host players. Spin up a private staging instance, confirm your plugins load, and report regressions while there is still time to fix them before release.
