Pufferfish on 1.21.3: common questions

Does Pufferfish support Minecraft 1.21.3?

Yes. 6 builds have been published for 1.21.3, the newest being build 27. 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 Pufferfish 1.21.3?

Java 21 or newer. The requirement comes from Minecraft 1.21.3 itself rather than from Pufferfish, so it applies to any server software running this version. A newer Java than that is fine.

Which Pufferfish build should I run on 1.21.3?

The newest one, build 27, published 20 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 Pufferfish'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.
