 # Changelog
 
+## [10.0.0-beta.4](https://github.com/adcontextprotocol/adcp-client-python/compare/v10.0.0-beta.3...v10.0.0-beta.4) (2026-10-31)
+
+
+### ⚠ BREAKING CHANGES
+
+* **protocol:** the SDK no longer advertises or accepts AdCP 3.3-beta.2. get_supported_adcp_versions is 3.0, 3.1, 3.2, 3.3-beta.3 and 3.2-rc.7; an adcp_version pin of 3.3-beta.2 or 3.3.0-beta.2 raises ConfigurationError, and a peer that advertises only 3.3-beta.2 for the 3.3 line negotiates down to 3.2. Re-pin to 3.3-beta.3 or omit the pin. adcp.reporting.subscriptions drops project_offering, project_reporting_delivery, project_subscription_state, project_subscription_coverage and serves_settled_subscription_fields, and ReportingSubscriptionEngine.subscription_coverage no longer takes adcp_version. The generated PriorVersion, AccountsWithException and AccountsUnauthorizedItem are now ReportingSubscriptionPriorVersion, ReportingSubscriptionAccountExceptions and ReportingSubscriptionUnauthorizedAccount.
+* **accounts:** AccountRegistry.ensure returns an AccountOutcome instead of an AccountRecord, billing= is optional and required only on the sync_accounts path, and a failed or rejected row is returned as AccountRejected instead of raised. AccountReady keeps account_id and status.
+
