MarsSeed [1] filed a request to merge 3mux-git [2] into 3mux [3]: Upstream is not actively maintained since 2021, except for 2 merged patches for MacOS build.
AUR/3mux-git is long abandoned and broken. But not worth keeping as per the above statement. AUR/3mux works, and is on the latest release version. [1] https://aur.archlinux.org/account/MarsSeed/ [2] https://aur.archlinux.org/pkgbase/3mux-git/ [3] https://aur.archlinux.org/pkgbase/3mux/
