Three new features, and a belated announcement:

1. The Thread Watcher can now auto-watch threads based on filters you’ve set in the “Filters & Highlights” menu. It works by fetching catalog JSON and matching filters against OPs on the specified board(s). Note that auto-watching only works when you select individual boards for a filter (“Boards” can’t be blank) and manually refresh the Thread Watcher, due to client-side CPU/bandwidth concerns (we may add a user specifiable timer in the future).
2. Threads now display the number of unique posters in a thread (based on IP). We’re trialling this as a way to give users an idea of how many active contributors there are in a given thread.
3. Delayed pruning was expanded to all boards except for /b/ some weeks ago. Per the original announcement, once a thread expires it is retained for a period of 48 hours before being pruned.
