ASPaper on 1.21.11: common questions

Does ASPaper support Minecraft 1.21.11?

Yes. 93 builds have been published for 1.21.11, the newest being build 17166. 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 ASPaper 1.21.11?

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

Which ASPaper build should I run on 1.21.11?

The newest one, build 17166, published 3 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 ASPaper'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.
