+## 0.4.11 (2023-12-21)
+
+### Improvements
+
+- Added handling for aggregation properties when initializing the integration, so it will patch the aggregation properties after creating the relations (PORT-5717)
+- Changed entity property in the `portResourceConfig` to be required instead of optional, as we don't support creation of blueprints as part of the app config (PORT-4549)
