garyvdm [1] filed a deletion request for meld-beta [2]: The new gtk3 port is now available in extra, so I don't plan on maintaining this package further. Those who want to use dev versions should rather use meld-git. [1] https://aur.archlinux.org//account/garyvdm/ [2] https://aur.archlinux.org//pkgbase/meld-beta/
