      - >-
        Support for MCP protocol revision 2026-07-28, served from the same endpoint as 2025-11-25, which
        remains fully supported. Clients on the new revision select a revision per request; older clients
        continue to negotiate at initialize. Tool names, input fields and result content are identical
        under both. No client action required.
      - >-
        tools/list results now carry ttlMs (3600000) and cacheScope public per SEP-2549, on the 2026-07-28
        path only — the tool catalogue is static and identical for every caller, so cache it.
  - version: '1.3.0'
    date: '2026-07-28'
    breaking: false
    added:
      - 'Allow: POST header and a documentation pointer on 405 responses from /mcp.'
      - Documented the RateLimit-* response header family.
      - Terms Of Use page (2026-07-26) plus links from the other documentation.
      - >-
        README overhaul (2026-07-26) — quick start with a complete working request, table of contents,
        endpoint summary table, full error catalogue (six money-value categories, exclusive-bound behavior
        of rate and period, enum categories, prose-to-camelCase parameter name map), the 429 body
        (details, retryAfter) and Retry-After header, the five MCP tool names mapped to REST equivalents,
        a "Using Results Well" section, a dedicated attribution section.
    changed:
      - >-
        Rewrote MCP tool and parameter descriptions for clearer model-facing guidance — the provider notes
        these descriptions are part of the interface and change as minor versions.
      - Moved shared response conventions into the MCP server `instructions`.
      - Endpoint paths written relative to the REST base URL, matching openapi.yaml.
    fixed:
      - >-
        Corrected conflicting base URL declarations in the README that could produce invalid /v1/v1/… paths.
