  Sparx Systems publishes two separate dated change streams that matter to an integrator: the
  Enterprise Architect product release/build history (per-version history.html pages on
  sparxsystems.com) and the release notes for the MCP Server add-in. The MCP server notes below
  were fetched verbatim; the product release train is recorded with lower confidence because
  sparxsystems.com serves a Cloudflare managed challenge to non-browser clients (HTTP 403), so
  its history pages could not be fetched directly during this pass.
