Setting ctype doesn't change anything when rendering as it is always overwritten on Feed.php line 306. `$this->ctype = ($format == 'atom') ? 'application/atom+xml' : 'application/rss+xml';` This seems to be missing a check to see if it has been set before. ``` if(null == $this->ctype){ $this->ctype = ($format == 'atom') ? 'application/atom+xml' : 'application/rss+xml'; } ```
