Lists the vintage dates of a FRED series: the dates on which its values were first released or revised (St. Louis Fed ALFRED). Use a date from this list as the as_of parameter of /series/{series_id} to read the series exactly as it was published then - the basis of a backtest that must not see later revisions. Newest first by default; limit bounds the list and the response declares when more dates exist.
