  None published. The release notes describe additions only; legacy discovery paths are kept live as aliases
  rather than removed (see lifecycle/). The 0.11.0 note records the MCP surface at 13 tools; the live server
  answers 41, so the tool set has more than tripled in eleven days without any entry describing a removal.
