Frequently asked

Does Multi-Threading work on Minecraft 1.21.10?

Yes. 1.21.10 is the newest Minecraft version Multi-Threading declares support for, and the claim comes from the author's own release metadata rather than from a compatibility list somebody maintains by hand.

Which Minecraft versions does Multi-Threading support?

Everything the author has declared, from 1.21.1 up to 1.21.10. The full list is in the table above, with the Java runtime each version needs next to it.

Do I need to install Multi-Threading on the client or the server?

The server only. Players join with an ordinary Minecraft client and install nothing.

Which platform or loader does Multi-Threading support?

NeoForge, Fabric. A build for one platform or loader will not necessarily load on another, so this is the first thing to check before the Minecraft version.

Which Java version do I need for Multi-Threading?

On the newest Minecraft version it supports, Java 21 or newer. The requirement comes from the Minecraft version you run rather than from the modpack itself, so on an older supported Minecraft the answer is that version's Java, not this one.

What licence is Multi-Threading under?

MIT, as stated by the author on the platform we synced it from. Check the project's own page before redistributing or bundling it.

How do I install Multi-Threading?

Use a launcher that imports packs, such as Prism Launcher, the Modrinth App or the CurseForge app, and open the pack file with it. The launcher installs the right loader and mods for you; installing a pack's mods by hand is the error-prone way.

Where do I download Multi-Threading safely?

Start with the author's page on Modrinth, which is where the data here is synced from. MCReference does not host or repackage files. The download link goes to the source recorded for that release; verify the publisher, filename and checksum before running it.
