Conductor and Java SDK monthly summary for 2025-03 focusing on simplifying and hardening WorkflowInstanceId handling by removing UUID support and enforcing string-only IDs across core and SDK. These changes reduce type-related errors, improve developer experience, and streamline validation and testing.

February 2025: Implemented annotation-based binding of the current workflow instance ID to worker task parameters across core conductor and Java SDK, with full UUID support. Introduced a new WorkflowInstanceIdInputParam annotation, integrated into AnnotatedWorker, extended validation and String-to-UUID conversion, and added tests. Achievements delivered parity between core and SDK with tests for both String and UUID types. Result: improved ergonomics, reliability, and end-to-end traceability by enabling direct access to the workflow instance ID within worker tasks.
