+## for Core-CMS v3.12
+
+### Redirect Deprecated Templates
+
+**If** the custom project directory:
+
+- has `templates/standard.html` or
+- has `templates/fullwidth.html` or
+- has `templates/home.html`
+
+Then:
+
+1. Copy the templates to become deprecated templates:
+    - from `custom_project_dir/templates`
+    - to `custom-project-dir/templates`
+
+    > **Warning**
+    > The name `custom_project_dir` **must** match the old name as it was, including dashes.
+
+2. Edit the deprecated templates to extend the new templates e.g.
+
+    ```django
+    {% extends "custom_project_dir/templates/standard.html" %}
+    ```
+
+3. Update `settings_custom.py` to support deprecated templates:
+
+    ```diff
+        ('custom_project_dir/templates/standard.html', 'Standard'),
+        ('custom_project_dir/templates/fullwidth.html', 'Full Width'),
+    +   ('custom-project-dir/templates/standard.html', 'DEPRECATED Standard'),
+    +   ('custom-project-dir/templates/fullwidth.html', 'DEPRECATED Full Width'),
+    ```
