+## [1.1.0] - 2025-12-08
+
+### Changed
+- Merged `EnhancedAgentDetails` into `AgentDetails` to unify agent detail typing across scopes and middleware.
+
+### Deprecated
+- `EnhancedAgentDetails` is now an alias of `AgentDetails` and marked as deprecated. Existing imports continue to work without breaking changes; migrate to `AgentDetails` when convenient.
+
+### Notes
+- This release is non-breaking. A minor version bump reflects additive API changes and deprecation guidance.
