FERMIPY IS A WIDELY-USED HIGH-LEVEL WRAPPER AROUND THE FERMI SCIENCE TOOLS SIMPLIFYING THE ANALYSIS OF LAT DATA AND PROVIDING NEW FUNCTIONALITIES THEREBY ENHANCING THE SCIENTIFIC RETURN OF FERMI ACROSS THE BOARD. IT HAS BEEN ALREADY USED FOR SEVERAL SCIENTIFIC PUBLICATIONS BOTH FROM WITHIN AND FROM OUTSIDE OF THE FERMI COLLABORATION. IN THIS WORK WE WILL MAINTAIN AND ENHANCE FERMIPY SUPPORT IT WITH BUG FIXES KEEP IT UP TO DATE WITH THE SCIENCE TOOLS AND REVIEW AND MANAGE INPUTS AND CONTRIBUTIONS FROM THE COMMUNITY THROUGH THE GITHUB INTERFACE. WE WILL ALSO IMPLEMENT NEW FEATURES SUCH AS FULL-SKY ANALYSIS FOR DIFFUSE EMISSION AND THE "BRACKETING IRFS" METHOD TO ASSESS SYSTEMATIC UNCERTAINTIES ON MODEL PARAMETERS.
