  OpticOdds maintains a dated changelog on its ReadMe-hosted developer hub,
  categorised Added / Improved / Removed. Entries are prose one-liners with no
  semantic version attached — the API is versioned by URL path (v3) and the
  changelog tracks changes within v3 rather than releases of it.

    or identifier values, and neither is flagged as breaking by the provider.
    There is no deprecation window, Sunset header, or advance notice attached
    to either.
  - >-
    Cadence is roughly monthly and the log is current — the newest entry is
    2026-08-07, twenty days before this pass.
