What is new in 1.21.11

Mounts of Mayhem was released on 9 December 2025 and is about mounts and mounted combat: a new weapon, new mounts and enemies that ride too.

Nautilus

You can tame, saddle and ride a nautilus under water. The zombie nautilus appears with a Drowned on its back.

The spear

A new weapon in every material, from wood to netherite, with a quick jab and a charge attack whose damage grows with your speed.

Lunge

An enchantment for the spear only: a jab pushes you forward. It does cost hunger.

Zombie horsemen

Zombie horses now spawn naturally, sometimes with a spear-wielding zombie on top.

Netherite horse armor

Upgrade diamond horse armor with a netherite upgrade template at the smithing table.

Camel husk

A desert mob with a spear-wielding husk in front and a parched behind.

Paper, Purpur, Vanilla or Fabric, in every version on our mirror. We add the right Java automatically.

Switch later

With the wizard in the panel you pick another type or version. We back up your server first, then it is reinstalled.

Plugins and mods

A plugin or mod has to support your server version. After a new release it often takes a while before everything is updated; check before you switch.

Players on the same version

A Java player connects with the version the server runs. When you switch, tell your players which version to pick in the launcher.

Frequently asked questions

Can I switch to another Minecraft version later?
Yes. With the wizard in the panel you pick another type or version. We back up your server first, then it is reinstalled with the right Java.
Does my world come along to a new version?
Minecraft converts a world to the new version as soon as the server loads it. Going back to an older version does not work well, so keep the backup from before the switch.
Will my plugins work on a new version?
Only if the plugin supports that version. Check the plugin page before you switch; after a big release, updates sometimes take a while.
Can players on another version join?
Not by default: a Java player picks the same version as the server in the launcher. With a plugin such as ViaVersion you can let newer clients join an older server.
