 ## Upgrading
 
+### 3.8.1
+
+This bugfix version potentially introduces a rename (and recreation) of one or more ServiceAccounts. It _only happens_ when you use one of these customization:
+
+```yaml
+# Case 1) - only happens when you do not specify a custom name (repoServer.serviceAccount.name)
+repoServer:
+  serviceAccount:
+    create: true
+
+# Case 2)
+controller:
+  serviceAccount:
+    name: "" # or <nil>
+
+# Case 3)
+dex:
+  serviceAccount:
+    name: "" # or <nil>
+
+# Case 4)
+server:
+  serviceAccount:
+    name: "" # or <nil>
+```
+
+Please check if you are affected by one of these cases **before you upgrade**, especially when you use **cloud IAM roles for service accounts.** (eg. IRSA on AWS or Workload Identity for GKE)
+
 ### 3.2.* 
 
 With this minor version we introduced the evaluation for the ingress manifest (depending on the capabilities version), See [Pull Request](https://github.com/argoproj/argo-helm/pull/637).
