yochananmarqos [1] filed a deletion request for catalyst-browser-rc- bin [2]: There hasn't been an RC in years and this package is very old. The latest stable version is 3.9.6. Upstream only releases beta versions before stable releases. [1] https://aur.archlinux.org/account/yochananmarqos/ [2] https://aur.archlinux.org/pkgbase/catalyst-browser-rc-bin/
