chreide [1] filed a deletion request for bas21-bin [2]: I'm the de facto maintainer of this package, and the author of the upstream software. We no longer maintain this legacy version. The software has moved to flatpak (and soon only web) and there is no longer a build to base this aur package on. Usage of this 1.x is discouraged.
