[arch-proaudio] How to rename an AUR package

Hey friendly people, an AUR package that I have created needs an update to a new version. At the same time, I was notified that I should rename it, i.e. add suffix "-bin" as it is a binary package. Could someone please explain to me what would be the best way to do this? A high level explanation should suffice. I am especially concerned about how to let existing users know of the package rename. Many thanks! Daniel
