MarsSeed [1] filed a deletion request for lib32-caps [2]: Unmaintained since 5 years, and seems not needed anymore.
Same is true for its only AUR dependent, lib32-alsaequal (deletion request submitted). [1] https://aur.archlinux.org/account/MarsSeed/ [2] https://aur.archlinux.org/pkgbase/lib32-caps/
