qBittorrent, the most popular BitTorrent client, has released version 5.3 and it is a big one, defaulting to supporting both v1 and v2 torrents. Previously you had to D/L a separate v2 client, and almost no one did that.
v2 torrents support individual file torrenting. If a file you want to D/L from a torrent is also included in 10 different torrents you now have 11 sources, not just the one from your initial torrent file. This should really help with abandoned torrents and disappearing files.
