  Cat Digital runs a dated "Release Notes" manager and a "News and Announcements"
  feed on the Digital Marketplace. Both are indexed and reachable by name, but the
  page bodies are behind a Cloudflare bot policy that answers 403 to every
  non-browser client, and Caterpillar's own copy says additional release-notes
  content requires login. So the changelog SURFACE is confirmed to exist and is
  linked; the structured entry list below carries only what could be established
  from outside that wall, and is deliberately short rather than padded.
