Ok, if a torrent changes it's contents (with the exception of renaming only),
the result is always a _new_ torrent, it does never change the old one.

What does happen now depends on what the tracker is done:

1. If the tracker does still track the old torrent file nothing does change.
   Everybody that still has the old torrent file can still share and download
   the old image like before.

2. If the tracker does no longer track the old torrent, all seeders and
   downloaders can continue their work with all their peer connections they
   already have but it becomes unlikely that they will get new connections.
   Thus inlike you use some alternative technologies, the swarm is slowly
   dying.

In no case does corruption occur from the protocol.
