  Cubic publishes no dated changelog page for this API. What it does publish is a revision
  history table on pages 1-2 of the feed documentation PDF, which is the only public record of
  how this contract has changed. It is transcribed here verbatim. Note the window: the most
  recent entry is more than five years old, and it records a host move rather than a change to
  the API surface.
