Minecraft 25w10a Update - What's New
The last snapshot before the 1.21.5 pre-releases. It brought the tntExplodes game rule from Bedrock, custom data on every entity, a new main menu panorama and new textures for test blocks.
Overview
Minecraft 25w10a is a weekly development snapshot for Minecraft: Java Edition, published on March 5, 2025. Snapshots are Mojang's weekly previews of in-progress features (development week 10 of 2025), shipped early so the community can test and report problems before anything is finalized. This one logs 8 changes you can try in a throwaway test world.
The work in this update spans changes and technical. On the changes side it brings new main menu panorama for the first drop of the year and Blocks broken by a piston now play their breaking sound.
This build is part of the development cycle leading to 1.21.5 (the Spring to Life drop). 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
Snapshots are opt-in through the official launcher. Always make a copy of any world before opening it in 25w10a, because development builds can corrupt saves and there is no guarantee the world will open in a later version. Use a fresh test world to try the new content safely.
For server admins
Do not run 25w10a on a public server. Snapshots are unsupported by server software and most plugins. 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
- Snapshots ship roughly once a week during active development and are enabled through the "Latest snapshot" toggle in the official launcher.
- The content here was being developed toward 1.21.5 (the Spring to Life drop); individual features may have been adjusted, renamed, or removed before that version shipped.
- Always keep a backup of important worlds before changing versions; the Astroworld versions database tracks client and server compatibility for 25w10a.
