This release improves feed handling and back end preview behavior. Legacy feed configurations now migrate the feed base URL correctly, while news feeds once again support their own base URL. In addition, fragment rendering in the back end has been adjusted to avoid issues with nested requests, and exceptions from fragment responses are now handled correctly in the preview.
