Feed Changes

Feeds are re-checked on a rolling basis: daily chart scans re-fetch each show's RSS feed at least weekly, and direct analyses re-fetch on demand. A change is recorded only when a previously observed value differs from the newly observed one; first-time detections are not listed. Hosting platform is detected from the servers that ultimately serve a feed's episode audio. Detection dates reflect when the change was observed, which can lag the actual change by up to a week.
