  Cvent publishes a single dated changelog for the whole Platform REST API, structured with
  Added / New APIs / New Tags / Updated / Deprecated sections per release. It runs continuously
  from September 2022 to the present — 68 dated releases — on a roughly biweekly cadence tied to
  Cvent's two-day release windows. Entry titles and section labels below are read verbatim from
  that page; highlights are recorded only for the two most recent releases, where the section
  contents could be attributed unambiguously.

deprecations:
  mechanism: '"Deprecated" sections in this changelog'
  occurrences: 14
  most_recent_year: 2025
  note: >-
    Fourteen releases between 2023 and 2025 carry a Deprecated section; none of the fifteen 2026
    releases listed above does. There is no Sunset/Deprecation response header, so the changelog
    is the only deprecation channel. See lifecycle/cvent-registration-lifecycle.yml.
