  ToolOracle publishes no standalone changelog page (/changelog, /docs/changelog 404). Dated change history lives in three
  machine-readable places — an x-changelog array inside the OpenAPI info block, "WITHDRAWN (date)" markers inside MCP tool
  descriptions, and a support_changelog MCP tool ("Recent changes, new tools, deprecations, breaking changes. Agents check to adapt.")
  on https://tooloracle.io/support/mcp/ — plus dated blog posts. This artifact captures the dated entries that were actually fetched.
