  document-history table of each versioned client specification. Entries below
  are the recent window from the Saturn Web Services specification (the most
  actively revised Euronext API document). The EWS specs carry their own
  histories (Indices v1.3 of 27 Jan 2020; EOD Summary v1.0 of 18 May 2016).
