Sponge on 1.21.1: common questions

Does Sponge support Minecraft 1.21.1?

Yes. 200 builds have been published for 1.21.1, the newest being build 252. This is not a declared claim: each build below is a real file the project released for this version.

Which Java version do I need for Sponge 1.21.1?

Java 21 or newer. The requirement comes from Minecraft 1.21.1 itself rather than from Sponge, so it applies to any server software running this version. A newer Java than that is fine.

Which Sponge build should I run on 1.21.1?

The newest one, build 252, published 4 h ago. Later builds for the same Minecraft version are bug fixes and performance work, so there is rarely a reason to run an older one deliberately.

Is this download official?

Yes. Every link points at Sponge's own release or API. MCReference does not mirror, re-host or repackage a jar; where the project publishes a SHA-256 we show it so you can verify the file you got.
