September 2025: Delivered two major features in wso2/carbon-identity-framework focused on reliability, performance, and maintainability. Replaced asynchronous event publishing with direct synchronous publish on the adapter manager, and enhanced webhook error handling with centralized decryption error management and prefixed error codes for clarity. Expanded test coverage for the new paths and error scenarios. Result: more predictable event delivery, faster incident resolution, and clearer observability.
