scheme: dated release notes per API release, grouped by year (2022–2026); no semantic version numbers — the API
  version string stays ea
current_version: ea
cadence: biweekly (a release pair roughly every two weeks)
entry_count: 71
latest: REST API Updates (August 19–20, 2026)
breaking_changes_recorded: false
note: Every entry is additive or corrective — new operations, new tags, new fields, filter documentation reformatting.
  The changelog records field-level deprecations (e.g. the attendee unsubscribed field) but no removal of an operation
  or a version retirement in the published window.
