note: >-
  Derrick publishes no dated changelog for the REST API itself; the only dated, versioned change
  history the provider ships is the derrick-mcp package changelog (recorded here verbatim, dates
  from the npm registry). Product-level changes surface on the public roadmap
  (https://derrick.productlift.dev/) without a dated archive.
