note: >-
  NSE publishes no API changelog page. The only dated, structured change history for its Web APIs
  lives inside the revision-history table at the front of each protocol PDF. The recent window for
  the RFQ Web API is transcribed below verbatim; the same pattern holds for the CBRICS (v1.16) and
  OFS (v1.3.4) protocol documents.
