  Two changelogs exist and they are about different things. The API changelog at DevNet has exactly
  two entries in three years and covers which API families are documented, not what changed inside
  them. The product release notes at docs.xdr.security.cisco.com move roughly weekly (2.72 on
  2026-08-19) but describe console features, not the contract. Neither one tells an API consumer
  that CTIA is now v2.71.0 or that IROH is at build 1.0.107 — those versions are only visible in
  the live x-iroh-version / x-iroh-api-version / x-ctim-version response headers.
