  Google Sites has NO API-specific changelog. It shares the Google Workspace developer
  release notes, a dated, per-product feed covering every Workspace developer surface.
  Searching that page for Sites entries on 2026-09-12 found exactly two substantive
  items across its whole history - both about the classic-to-new Sites transition,
  neither a change to the Sites Data API itself. The Sites Data API's own version has
  been frozen at GData 1.4 with "a single supported version"; nothing has shipped to it
  in the release notes window.

    type: feature
    breaking: false
    summary: >-
      Reports API added the Google Sites customer usage report to
      customerUsageReports.get, letting admins view Google Sites usage across a domain.
      This is the Admin SDK, not the Sites Data API.

    No changelog entry has ever announced the Sites Data API deprecation. It is
    communicated only as an HTML banner on the documentation, with no date and no
    sunset.
