I should have done this earlier.
Now supports minecraft 1.21.4
This version was actually tested in the minecraft launcher!
This version of the mod has been compiled with java 22 due to wich it is incompatible with all versions of the game as even minecraft 1.21.4 recognises only versions compiled with java 21 or below.
Sadly I cannot take down a version wich I have already uploaded so it'll have to stay here.
Should you attempt to load this file, then the game will crash before you even get to the mojang logo.
Do not use this!!
It works with 1.21.3 too
A bit of screaming at gradle later and it's now compiled with java 17 and hence compatible with all versions from 1.19 all the way through to 1.21.1
It should work with this version too... Seems like it.
Works only in public chat and not with No Chat Reports encryption.
