I am not a developer myself, only user, and have no idea how github works. But my developer is a Prestashop partner so maybe they have left some notes somewhere. I have same username HelenI in Prestashop forum and I have written some about my experience using ASM.
I have also done some over-the-Internet user tests with Guillaume from Prestahop to give my feedback on stock management in Prestashop.
ASM is dead to Prestashop and 1.7. does not help with inventory management in any way. So I dont think they will work on it anymore.
