+#### New Helmfile default: Restricting characters for directory and filenames in fileshare module
+
+**Target group:** All openDesk deployments using the fileshare module, as they may already contain files or directories with characters that are now restricted.
+
+openDesk now enforces restrictions on the characters allowed in directory and filenames by explicitly disallowing the following set: `* " | ? ; : \ / ~ < >`
+
+The reason is that desktop clients can not handle all characters due to restrictions in the underlying operating system and therefor syncing these directories and/or files will fail.
+
+This change was introduced because desktop clients cannot reliably handle certain characters due to operating system limitations, causing file synchronization to fail when these characters are present.
+
+For existing deployments, any files or directories containing restricted characters must be renamed before updates within the file or (sub)directory can succeed.
+
+Nextcloud provides tooling for renaming affected files using an [`occ command`](https://docs.nextcloud.com/server/latest/admin_manual/occ_command.html#sanitize-filenames) that can be executed by the operator, the command also supports a dry-run mode.
+
+You can customize the default restriction settings in `functional.yaml.gotmpl`:
+
+```
+functional:
+  filestore:
+    naming:
+      forbiddenChars:
+        - '*'
+        - '"'
+        - '|'
+        - '?'
+        - ';'
+        - ':'
+        - '\'
+        - '/'
+        - '~'
+        - '<'
+        - '>'
+```
