Leaf on 1.21.5: common questions
Does Leaf support Minecraft 1.21.5?
Yes. 49 builds have been published for 1.21.5, the newest being build 68. 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 Leaf 1.21.5?
Java 21 or newer. The requirement comes from Minecraft 1.21.5 itself rather than from Leaf, so it applies to any server software running this version. A newer Java than that is fine.
Which Leaf build should I run on 1.21.5?
The newest one, build 68, 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 Leaf'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.
