Will there be a version for 1.20+ at some point? I saw some people talking about 1.19.3 but nothing about 1.20s so I was just wondering

No rush of course! Love the mod!!!!!

Still works in 1.20.4 by having a config/fabric_loader_dependencies.json:

{
	"version": 1,
	"overrides": {
		"betterbiomeblend": { "-depends": { "minecraft": "" } }
	}
}

}

It didn't work for me for some reason. I made a .json file because I didn't have one in the config folder and pasted what you said in the comment.

Here's the log when I try starting the game, it might help.

Hmm I think I only tested it in a modpack which also had Indium?
