 ### Fixed
 
+- Freeing disk space counts only the people who subscribe to a feed: an episode is no longer taken as heard by everyone because someone who has since unsubscribed heard it, and their pins no longer keep files for good.
 - An episode whose file turns out to be a torrent shows as downloaded once it is, instead of being fetched again on every check of its feed, and no longer holds up the checking of other feeds while it downloads and seeds.
 - Downloading the latest 65 to 100 items of a feed queues them at once, instead of hanging until most had downloaded and holding up adding feeds and Refresh meanwhile.
 - Changes to the feed list made at the same moment, such as two people adding feeds, or a feed added while the server settings change, no longer undo one another.
