  CDISC publishes change information in three separate places, and only one of them is machine-readable to an
  unauthenticated client. The CDISC Library API's own release notes live in the Atlassian knowledge base, which
  is served behind a Cloudflare bot challenge; the dated, structured change history that IS readable belongs to
  the open-source CORE rules engine on GitHub.

  transcribed here — the release bodies are long and change often; follow the feed URL for the detail.
