Minecraft 24w36a Update - What's New
A 1.21.2 snapshot that let data packs and resource packs define their own equipment. Bundles in the hotbar empty one group of items at a time, squid spawn eggs only give adults, and converted mobs keep their share of health.
Overview
Minecraft 24w36a is a weekly development snapshot for Minecraft: Java Edition, published on September 4, 2024. Snapshots are Mojang's weekly previews of in-progress features (development week 36 of 2024), 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 experimental features, changes, and technical. On the experimental features side it brings a bundle used from the hotbar drops one group of items at a time.
This build is part of the development cycle leading to 1.21.2 (the Bundles of Bravery drop, after 1.21). 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.
Changes

Known Issues

- Ender pearls could teleport to the wrong location in this snapshot
What This Means
For players
Snapshots are opt-in through the official launcher. Always make a copy of any world before opening it in 24w36a, 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 24w36a 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.
