  SegmentStream has no developer changelog. Product changes are announced as
  dated posts in the "Product Updates" category of the marketing blog, written
  for marketers rather than integrators — they carry no version number, no
  breaking-change flag, and no per-endpoint or per-tool diff. docs.segmentstream.com/changelog
  and segmentstream.com/changelog both return 404.

  - title: What's new in SegmentStream — May '26
    date: '2026-05-18'
    url: https://segmentstream.com/blog/product-updates/may-2026-product-update
    breaking: false
    additions:
      - Predictive Cross-Channel Attribution
      - Self-Reported Attribution surfaced inside every User Journey
      - Adobe Analytics integration
      - Snowflake integration
    highlights: Plus assorted UI enhancements.
  - title: Visit Scoring is becoming Predictive Attribution
    date: '2026-05-06'
    url: https://segmentstream.com/blog/product-updates/visit-scoring-becomes-predictive-attribution
    breaking: false
    renaming: true
    additions:
      - >-
        The machine-learning capability previously shipped as the standalone
        Visit Scoring attribution model becomes an additional layer that applies
        across all attribution models.
    highlights: >-
      A product rename with a behaviour change. Agents and integrations that
      referenced the "visit-scoring" model by name are the population affected,
      but no deprecation notice, sunset date or migration note was published
      alongside it.
  - title: Introducing the SegmentStream MCP Server
    date: '2026-02-25'
    url: https://segmentstream.com/blog/product-updates/introducing-segmentstream-mcp-server
    breaking: false
    additions:
      - >-
        Hosted Model Context Protocol server at https://mcp.segmentstream.com/mcp,
        letting AI assistants connect to and act through the measurement and
        optimization engine.
    highlights: The launch of the provider's primary agent surface.
gaps:
  - >-
    No entry records a change to the MCP tool surface itself. The server exposes
    ~63 tools (mcp/segmentstream-mcp.yml) and there is no published record of
    when a tool was added, renamed, or removed — the highest-value missing
    signal for an agent integrator, since tool names are the call contract.
  - >-
    No RSS/Atom feed or machine-readable changelog was found for the product
    updates category.
