🆕 How to allow newer versions of Minecraft
In order to allow more recent Minecraft versions to join your server, you need to install the plugin ViaVersion.
If you would like to add backward compatibility to your server (all the way back to 1.9) then you need to use a plugin called ViaBackwards which requiresViaVersion.
This allows all versions of Minecraft from 1.9.x to 1.13.x to join your server, although it can be buggy sometimes. Luckily the developers are constantly improving it.
