You have an example I see no issues using the latest rss feed nor have there been any changes in that script for a few versions really. I do not beleive that script other than changing the version number has changed since it was reworked in the 4 series. It is a self contained script.
Remember if you do not allow guests to view content they will not be able to view content in the rss script.
