+
+### Fixed
+
+- **`listUnifiedExecutions` deserialization**: Fixed Jackson deserialization failure on `UnifiedListExecutionsResponse` — added `@JsonCreator` and `@JsonProperty` annotations to constructor. Without this, `listUnifiedExecutions()` threw "no Creators, like default constructor, exist" error.
+- **SSE streaming endpoint path**: `streamExecutionStatus()` now uses correct `/api/v1/unified/executions/{id}/stream` path (was incorrectly pointing to `/api/v1/executions/{id}/stream` which is the Execution Replay API)
