utils.mkOverlays required being output as outputs.overlays.${system}.packagename
This does not match the flake schema.
A new function has been created, utils.makeOverlays
It is called in the final outputs outside of the flake-utils like where the mk*Module functions are called instead of inside where mkPackages is called
The utils.mkOverlays is being depreciated and may be entirely removed eventually.
This will require a slight modification to your flake.nix, view the main flake.nix file, or the templates for guidance, simply delete the old overlays output, and paste the new one in.
