Namespace: I just made two important changes to the location and person tags that are breaking changes. After some discussion with Angelo at Blubrry, we decided to remove the name="" attribute from these tags and move that string to the element's node value.
<podcast:person name="Dave Jones" />
Same with location:
<podcast:location name="Mount St. Helens" />
<podcast:location>Mount St. Helens</podcast:location>
@Castopod@dave Maybe it makes sense for me to hold off on updating till you have updated your feed, since you're the only place I know of that has this. Then I can test out if the changes works instantly :)
