Paper on 1.21.11-pre4: common questions

Does Paper support Minecraft 1.21.11-pre4?

Yes. 5 builds have been published for 1.21.11-pre4, the newest being build 13. 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 Paper 1.21.11-pre4?

Java 21 or newer. The requirement comes from Minecraft 1.21.11-pre4 itself rather than from Paper, so it applies to any server software running this version. A newer Java than that is fine.

Which Paper build should I run on 1.21.11-pre4?

The newest one, build 13, published 9 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 Paper'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.
