  The OneNET Studio 更新日志 (release log) is the only dated, structured changelog China
  Mobile publishes for any API. It is thin — two entries — and has not been updated since
  2021, while the platform documentation itself has moved to a newer generation at
  /doc/v5/develop. Product-level change traffic runs instead through the untimestamped
  平台公告 (platform announcements) board. The IoT Card, communication-capability and
  internet-capability platforms publish no changelog at all.
