+### Observations
+
+Comparing to Flux v2.2, in Flux v2.3 helm-controller memory management has
+improved a lot, especially when the cluster has hundreds of CRDs registered.
+In Flux v2.2, helm-controller on Kubernetes v1.28 is running out of memory
+with 100 CRDs registered, while in Flux v2.3 on Kubernetes v1.29
+it can handle 500+ CRDs without issues. Given this results,
+it is recommended to upgrade the Kubernetes control plane to v1.29
+and Flux to v2.3.
