FeedDiscussionsPlus Plugin updated to support 2.5 (as well as 2.3)
Supporting both versions concurrently turned out not to be that simple. Sorry for the delay...
Let me know if you have any issues.
(For curious developers: The plugin is back-end heavy that required deviation from the standard Vanilla plugin setup process and that in turn required different approaches in 2.3 and 2.5 - double the work in order to provide the user interface my intranet users wanted.)
