Minecraft 1.21-pre3 Update - What's New
Third pre-release addressing final issues before the 1.21 release candidate. Focused on polish and stability.
Overview
Minecraft 1.21-pre3 is a pre-release for Minecraft: Java Edition, published on June 5, 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 addresses remaining crash issues and ominous trial event reward balancing. 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 (Tricky Trials). 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-pre3 is close to final but still a test build. It is a good way to preview 1.21 early, but keep your main world on the current stable version until the full release lands.
For server admins
Do not run 1.21-pre3 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.
Background & Context
