No seriously what is going on with this mod? 1.16 and 1.17 and 1.18.1?

I have heard nothing on it in forever, and I'm a massive fan of the Giant Redwood trees from this mod...

So, where the heck is the version for 1.18.1?

or can someone make me a mod that latterly just adds the Giant Redwood Trees for 1.18.1?
