Which Java for which Minecraft

A server needs the Java its Minecraft version was built for. The wrong one does not start, and the error rarely says why.

On FadeHost the Java follows the version: switch a server from one release to another and it starts with the right Java on its own. What Java errors look like.

Questions about versions

What is the latest Minecraft version?

Minecraft: Java Edition 26.3, released on September 15, 2026. The update is called Wilderness Bound.

Why is it Minecraft 26 and not 1.22?

Since 26.1 the number is year.drop.hotfix: the first part is the year, the second counts the game drops of that year, and a third marks a hotfix. 26.1 was the first release on it; the release before it was 1.21.11.

Which Java version does a Minecraft server need?

It depends on the Minecraft version: 26.1 to 26.3 needs Java 25; 1.20.5 to 1.21.11 needs Java 21; 1.18 to 1.20.4 needs Java 17; 1.17 to 1.17.1 needs Java 16; 1.7.2 to 1.16.5 needs Java 8. On FadeHost the server starts with the right Java for its version on its own.

Can I run a server on an older Minecraft version?

Yes. Every release listed here can be picked when you create a server, and an existing server can be switched from the panel. Older versions are common for modpacks, which stay on the version they were built for, and for PvP servers.

Can a world go back to an older version?

No. A world opened in a newer version is converted and cannot be opened in an older one again. Take a backup before you update, and keep it until you are sure.
