Frequently asked

Does Vanilla Backport Compat work on Minecraft 1.21.1?

Yes. 1.21.1 is the newest Minecraft version Vanilla Backport Compat 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 Vanilla Backport Compat support?

Everything the author has declared, from 1.20.1 up to 1.21.1. The full list is in the table above, with the Java runtime each version needs next to it.

Do I need to install Vanilla Backport Compat on the client or the server?

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

What does Vanilla Backport Compat need to run?

It declares Vanilla Backport as required, so that has to be installed alongside it or it will not load. Each one is linked in the dependencies section above.

What licence is Vanilla Backport Compat 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 Vanilla Backport Compat?

Data packs install per world: put the downloaded file in that world's datapacks folder and run /reload, or add it when creating the world. No loader is involved. On a server, the world folder lives next to the server jar.

Where do I download Vanilla Backport Compat 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. When available, recorded download links go to the source for that release; verify the publisher, filename and any available checksum before running it.
