Recently upgraded from 1.21 to 1.21.1 and pretty much all of the mods I wanted to run are either updated for 1.21.1, or aren't, but still works on 1.21.1.
Regions Unexplored is one of the very very few 1.21 mods I ran that does -not- work on 1.21.1. Crash right away at startup.

So my question is pretty simple.
Will RU be updated for 1.21.1 (or simply 1.21.x)?
If yes, is there a potential timeframe for that?

I am in no way demanding that it should be updated. It's your mod and you do what you want with it. I'm merely asking so that I know what the plans are. :)
Cheers!

We will be updating to 1.21.4 (as that's latest as of rn), just got to find the time to do since well. Irl responsibilities etc. Sorry about that

Would it be possible to make it 1.21.x then? So it works with both .1 and .4 ?
