As for datapack version beta.0.17.0 I can't say the required versions for sure, just use the newest possible.

This is a Datapack, not a Mod.  (Guide on installing a Datapack at the bottom of the page.)

Project still in development, beta builds are stable to play unless otherwise stated, you can help by sending feedback on the Origins and what you think could fit in there.
Development is currently slowed down until I can make free some more of my time for it.
