A small ViaVersion addon. (As it only works with ViaVsersion duh)
Get it on SpigotMC
I wrote the code in a few hours back at the end of 2021, up until January 9th, 2022. Since then i have not worked on it.
It should work still fine, it won't add new versions to the config file automatically.
In the config files (and on Spigot) you can read how to add them.
The plugin only interacts with the Viaversion API.
The plugin has BStats integration.
