1.21 now would be great 😊
Thank you for the effort.

I just wanted to test it with other mods for a bit and discovered that there is practically no content mods for Fabric 1.20.6, lol. And all "modpacks" are basically vanilla + sodium + REI

I will not touch 1.21 untill its finished (that is, 1.22 starts to come out). Porting is a massive pain in the ass, tbh I had hoped that just changing numbers in gradle.properties and renaming a few classes would be enough but it was not, and even such a small mod took me a whole day to port. And Im still thinking about porting villager trades mod... And about porting RELT to forge, because, apparently, its much more useful for modpacks than for vanilla game... Idk, too much routine work for a game that I barely even play nowadays

Yet it's finished, if you plan support for minor versions with possible big changes (ouf), that's on you.
But I get your decision 😊

I have updated my fork of this mod to 1.21, if you are interested in that you can grab the release from here.
Additionally, I have opened a pr so the update might get integrated in the mod itself

Thank you so much @tyrannus00!
I tested your fork right now, works fine on the Client but my server got this crash: https://pastebin.com/raw/Yf2eUAt7
Tested on newest REI release "RoughlyEnoughItems-16.0.744-fabric.jar".

Can soon be closed when @GrigLog accepts your PR 😄
