When joining the server the message doesn't get relayed to discord, leaving messages does relay thought.

Unless you are using the version from our snapshots, 1.20.6 is not supported, so it won't work

Would you know when we might expect support for version 1.20.6?

We aren't doing any official 1.20.6 releases, for a variety of reasons, but the good news is, there are 1.20.6 versions that are available for use.

Since it's server side, you can use it without the players having it.

CraterLib - 1.20.6
SDLink - 1.20.6

That's good to know although I won't be able to use it on Aternos

1.21 was released today. Going to close this for now, since we never officially supported 1.20.6
