The one argument argument I would make towards mentioning LISTEN/NOTIFY is that there is a big push on the development side to do more evented-programming. While it is not a new feature, I think you could attract a new set of developers by showing what LISTEN/NOTIFY can do. One of the most requested features for the new version of Redis was a similar publish/subscribe type system, but of course in this case it was new.

Now while I understand that this is not a new feature, a good way to capture some of the evented-programming interest is to make some follow-up blog posts after the announcement showing some examples of using LISTEN/NOTIFY and perhaps mentioning the improvements.
