Just a quick note with more about the Releases RDF we have here at PHPDeveloper.org:

If you'll remember a few days ago, we announced that our Releases RDF was pulling items from the phpClasses.org website to announce new classes, well, more work has been done to so the same thing for SourceForge and their software announcements. The Releases RDF will now (hourly) be updated with their latest content as well....

UPDATE: while the ball was rolling, I decided to go all the way with it, and get data from Freshmeat.net as well. Hopefully, this will help to cover quite a bit of the larger PHP-related software releases....
