Opera had torrent support at the time I stopped using it, I never heard they had discontinued that feature but I'm assuming they did, both because it probably would have been mentioned in this comment chain already and also because making that decision should have been inevitable. I never used bittorrent before joining oink, I think I remember on joining thinking I would just use opera and then installing utorrent after finding out client whitelisting was a thing. Maybe I was already on oink when opera added the feature and I thought I'd try it because I was already using opera. Maybe this is all a fever dream, who can really say.
