summary: >-
  3GPP has no prose changelog page for its APIs. The real changelog is git: the OpenAPI documents live in
  GitLab on forge.3gpp.org, one long lived branch per Release, and every TSG plenary produces a tag per
  Release. The tags below were read from the live repositories on 2026-07-25 and are the machine readable
  record of what the API set looked like at each plenary.
