+## Breaking Changes
+- Agent refactoring: this release comes with many new improvements to the Akri agent!
+  - In order to prevent deletion of existing Instances on Configuration update, the agent now only looks for updates to the capacity and broker capacities.
+  - Agent no longer needs access to the CRI socket for slot reconciliation.
+  - Added a finalizer to ensure clean-up of resources.
+- Update to the Instance CRD to better handle upgrades.
