 A major chart version change (like v1.2.3 -> v2.0.0) indicates that there is an incompatible breaking change needing manual actions.
 
+### From 51.x to 52.x
+
+This includes the ability to select between using existing secrets or create new secret objects for various thanosrule config. The defaults have not changed but if you were setting:
+* `thanosRuler.thanosRulerSpec.alertmanagersConfig` or
+* `thanosRuler.thanosRulerSpec.objectStorageConfig` or 
+* `thanosRuler.thanosRulerSpec.queryConfig` 
+
+you will have to need to set `existingSecret` or `secret` based on your requirement
+
+For instance, the `thanosRuler.thanosRulerSpec.alertmanagersConfig` used to be configured as follow:
+
+```yaml
+thanosRuler:
+  thanosRulerSpec:
+    alertmanagersConfig:
+      alertmanagers:
+        - api_version: v2
+          http_config:
+            basic_auth:
+              username: some_user
+              password: some_pass
+          static_configs:
+            - alertmanager.thanos.io
+          scheme: http
+          timeout: 10s
+```
+
+But it now moved to:
+
+```yaml
+thanosRuler:
+  thanosRulerSpec:
+    alertmanagersConfig:
+      secret:
+        alertmanagers:
+          - api_version: v2
+            http_config:
+              basic_auth:
+                username: some_user
+                password: some_pass
+            static_configs:
+              - alertmanager.thanos.io
+            scheme: http
+            timeout: 10s
+```
+
+or the `thanosRuler.thanosRulerSpec.objectStorageConfig` used to be configured as follow:
+
+```yaml
+thanosRuler:
+  thanosRulerSpec:
+    objectStorageConfig:
+      name: existing-secret-not-created-by-this-chart
+      key: object-storage-configs.yaml
+```
+
+But it now moved to:
+
+```yaml
+thanosRuler:
+  thanosRulerSpec:
+    objectStorageConfig:
+      existingSecret:
+        name: existing-secret-not-created-by-this-chart
+        key: object-storage-configs.yaml
+```
 ### From 50.x to 51.x
 
 This version upgrades Prometheus-Operator to v0.68.0, Prometheus to 2.47.0 and Thanos to v0.32.2
