note: 'Cvent publishes a dated changelog for the whole /ea REST contract on a roughly two-week cadence, 71 entries
  deep, running back to September 2022. Only the ten most recent releases are captured here — this is a recent-window
  artifact, not a mirror. Items are the operations, schemas, enums and scopes each release names, transcribed
  from the page. Hospitality-relevant rows (Housing, RFP Management, Venue Profiles, Venue Meeting Rooms, Travel
  RFPs, Event Travel) appear throughout, which is the useful signal: the hospitality surface is actively shipping,
  not parked.'
