In recent months I released new, limited versions of the mod for 1.20.1, 1.20.2, and 1.18.2. I know there are newer versions of Minecraft, and I plan to get to them, too! First things first, though: Folks requested these versions on the Discord server, so those are what I targeted first.
As far as the mod being limited to the four original horse breeds right now, that's being fixed right now. The reason I released the mod with only four is because I wanted to focus on getting new magical horse models working, and get something out for people to use in a short time frame, especially since development was taking me a long time when I had less availability. If I had waited until I had all the horse breeds finished before releasing, none of these versions would be available even today.
I've been wanting to do this for a long time, and I'm happy to finally be able to give The Ultimate Unicorn Mod the attention it needs! Come and see me on the Discord Server!
Oh yeah, almost forgot: a new release is coming out in the next day or two.
