9.0.0 (2026-10-24)

⚠ BREAKING CHANGES

  • reporting: the PostgreSQL reporting stores, the row storage providers, the change feed, the ownership-migration helpers and ReliableReportingService.postgres leave adcp; install adcp-reporting-storage[pg] (plus gcs/s3/azure) and import them from adcp_reporting_storage. The adcp[reporting-gcs], [reporting-s3] and [reporting-azure] extras are removed. See docs/reporting-storage-package-migration.md.
  • codegen: a JSON document carrying null for an optional property whose schema does not admit null is now refused by model_validate_json and TypeAdapter.validate_json, and the published JSON Schema of such a property has no null arm. A Python None is still accepted. JSON produced with exclude_none=False must be read back in Python mode (model_validate(json.loads(...))).
  • types: SyncCreativesRequest.creatives is now list[CreativeAsset] | None. Handlers must guard it before iteration or use request.creatives or [] for assignment-only requests.
  • compat: server handlers receive requests already upgraded to the latest supported minor. A 3.1 buyer's request reaches the handler as adcp_version: "3.2", so reading the version from handler params, including resolve_requested_adcp_version(params), returns the served version, not the buyer's. Read ToolContext.resolved_adcp_version for the buyer's negotiated version and answer in the latest shapes; the SDK converts the response down. (Added after release.) (#1559)
