dario773 [1] filed an orphan request for zathura-cb-git [2]:

No activity for several years

I assume it went under the radar, that this specific PKGBUILD is maintained by a different person than the other zathura related PKGBUILDs? Firstly: Years of inactivity is not valid as it got an update in the beginning of 2022. And a comment from 2019 isn't an indicator of activity. Secondly: In general: Those are -git packages, where it can be normal that there is a long time no activity because of dead/slow upstream or no breaking changes. But dunno about the state of the other zathura related PKGBUILDs. Are those broken in their current state? Best regards
