Spigot on 1.21.6: common questions

Does Spigot support Minecraft 1.21.6?

Yes. 13 builds have been published for 1.21.6, the newest being build 4518. 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 Spigot 1.21.6?

Java 21 or newer. The requirement comes from Minecraft 1.21.6 itself rather than from Spigot, so it applies to any server software running this version. A newer Java than that is fine.

Which Spigot build should I run on 1.21.6?

The newest one, build 4518, published 13 mo 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 Spigot'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.
