(1.16.5 Forge)What's "expandability 2.00 or above"?

I downloaded the "Artifacts" mod, and I did the process of installing it, then when Minecraft launched it said "Mod artifacts requires expandability 2.00 or above"? Is this like how some mods need Curious API or smth? i can't figure it out.

It's a Mod that is required by Artifacts, you need to add the Mod with version 2.00 or above
