Mod help? please

I just downloaded 0.A-1706 and it says that the medieval and old guns mods are obsolete. Does this mean that they do not work anymore or that the stuff in them was added in to the game and they are not needed?

They are now in the game by default, if you want them out*, you need to enable the “No_medieval_weapons” mod or similar.

*Which was the whole point of breaking them out into mods in the first place.
