I see 1.19.4 branch. But will it support 1.19.2 as well?
1.19.4 is more like 1.20 snapshot packed as minor dot release.
But in reallity 1.19 modding mostly popular on 1.19.2.

Thanks for clarifying. Really excited for this mod on modern mc versions. I remember it being one of my favorites back in 1.16 versions. Thank you for your efforts and good luck! :)

I do plan to support all versions 1.18.2 and onward! The main reason for there being a 1.19.4 branch was because that was the latest version of the architectury template available at the time, so I made things work in that version first.
