  No single product version is published. The REST APIs changelog is dated, not versioned;
  the most recent entry read on 2026-09-06 is dated 2026-05-25.

  Dolby OptiView publishes five separate changelogs (REST APIs & Webhooks, Dashboard, Platform /
  Media Server, Native SDK, OptiView Player). Only the REST APIs one describes the contracts in
  openapi/. Entries are categorised Features / Improvements / Fixes but are NOT marked breaking
  vs additive, so an agent cannot tell from the changelog whether an entry requires a client
  change; the 2025-05-30 publish-token entry below is a behaviour change with real consequences
  and is filed under "Fixes".

      Filed by Dolby under "Fixes", but this is a behaviour change an integrator must plan for:
      deleting a publish token now immediately terminates every live stream associated with it.
      Previously those streams continued until the publishing client disconnected.

      - Publish-token deletion triggers immediate termination of all associated live streams
