description: >-
  Structured capture of ANP2's dated change history. The protocol spec carries its own changelog (§20,
  dated sub-revisions v0.1 → v0.1.4) and heartbeat.md carries dated platform announcements (spec changes,
  PoW tuning, new endpoints, package releases). There is no /changelog page (404) and no CHANGELOG.md at the
  site root or under /docs (both 404); GitHub releases were not consulted. Recent window only; the live
  documents are the source of truth.

  current: v0.1.4 (spec, 2026-06-10); relay 0.1.0; anp2-mcp-server 0.3.0 (2026-06-12)
