+## 1.2.2
+
+**Release date:** 2024-02-01
+
+This patch release comes with various bug fixes and improvements.
+
+Reconciling empty directories and directories without Kubernetes manifests no
+longer results in an error. This regressing bug was introduced with the
+controller upgrade to Kustomize v5.3 and has been fixed in this patch release.
+
+The regression due to which the namespaced objects without a namespace specified
+resulted in `not found` error instead of `namespace not specified` has also been
+fixed. And the regression due to which Roles and ClusterRoles were reconciled
+over and over due to the normalization of Roles and ClusterRoles has also been
+fixed.
+
+In addition, the Kubernetes dependencies have been updated to v1.28.6. Various
+other dependencies have also been updated to their latest version to patch
+upstream CVEs.
+
+Lastly, the controller is now built with Go 1.21.
