description: >-
  Cisco publishes an "API Changelog" page for the Support APIs. As fetched on
  2026-08-19 it contains no entries. Each of the eight APIs gets one heading and one
  sub-heading reading "(changelog begins)", with no dated entry beneath it — the
  page is a scaffold that was stood up and never filled in. That is recorded here as
  the finding, not papered over: a consumer of these APIs currently has no published
  record of what changed, when, or whether a change was breaking.

    note: >-
      Cisco's Developer Support page names this forum as "your primary source for
      official updates". It returns 403 to an anonymous client, so the only stated
      channel for API change announcements is not anonymously readable either.
