+## [10.0.0-beta.0](https://github.com/adcontextprotocol/adcp-client-python/compare/v9.0.0-beta.3...v10.0.0-beta.0) (2026-10-27)
+
+
+### ⚠ BREAKING CHANGES
+
+* **protocol:** the wire pin is AdCP 3.3.0-beta.0 (adcp_version "3.3-beta.0" by default; pin adcp_version="3.2" for a 3.2 contract). adcp.types.UniversalMacro is a RootModel union; the closed enum is UniversalMacro3. The identity preview modules are removed and adcp.types.experimental_identity binds the generated 3.3 types (RequestSigning.profiles is list[Profile], PrincipalChangedWebhook.reason is the generated enum). adcp.signing.identity_schema_bundle is removed. Legacy RFC 9421 SigningConfig / RequestSignatureVerification construction emits a DeprecationWarning. evaluator_id is gone from evaluator specs. See MIGRATION_v9_to_v10.md.
+* **a2a:** With request signing configured, A2A requests that break the AdCP 3.3 operation-resolution hardening clauses (duplicate or case-variant keys, batches, malformed Parts, extra DataParts, mismatched task continuations) are refused with request_body_malformed or INVALID_REQUEST.
+* **webhooks:** WebhookReceiver rejects bodies over 1 MiB (was 10 MiB) and JSON deeper than 64 or with more than 100,000 members with HTTP 413 before signature verification, and adds the rejection reasons body_too_complex, content_encoding_unsupported and body_framing_invalid. Client responses past the depth or member bounds raise ADCPResponseTooComplexError.
+* **signing:** BrandJsonJwksResolver and the other brand.json fetchers raise ValueError for max_body_bytes above 2 MiB, the AdCP 3.3 cap verifiers must not read past.
+* **canonical-formats:** PixelTrackerDowngrade.v1 is now V1UrlTracker or None. Check it before reading asset_id or url. See MIGRATION_v9_to_v10.md.
+* **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.
+* **signing:** adcp.signing.b64url_decode accepts only RFC 7515 base64url (no padding, no standard-alphabet characters, no non-zero trailing bits) and raises ValueError for anything else. public_key_from_jwk reads a JWK through joserfc, so its ValueError text changes. private_key_from_jwk raises ValueError when a JWK's x (or y) isn't the public key of its d. adcp.signing.publisher_pins.jwk_thumbprint returns the RFC 7638 thumbprint as a base64url str instead of the digest bytes.
+* **types:** adcp.types.generated_poc no longer imports. Use adcp.types.domains, or run adcp migrate v3-to-v4 --apply.
+* **reporting:** row storage tables, provider inputs and locators are renamed to the AdCP names above, REPORTING_ROW_ENCODING_V1 is replaced by REPORTING_ROW_FORMAT_V1 and REPORTING_ROW_ALGORITHM_V1, and {period_date} renders the source timezone date as YYYY-MM-DD instead of the UTC date as yyyy/MM/dd, and a custom key template without {revision_key} is refused unless its binding is read_only. create_schema migrates existing databases; stop older writers first.
