Tell feature requesters when their feature ships

For a small paid web service with a few hundred real users, people who send thoughtful feature requests are often the most engaged customers. A common problem is that the requested feature may be built weeks later, but the person who asked for it never hears about it.

The original request gets buried in old messages or comments, and finding the requester later feels like too much work. As a result, a customer may leave quietly without knowing the feature they wanted is now available.

A public changelog alone may not close the loop with the exact people who cared enough to ask. A simple way to track requests, requesters, and shipped features can help keep those valuable users close.
