+# Migration from `1.7` to `1.8`
+
+## Config files
+
+- The config version have been changed
+- You can now configure restore hooks
+
+See detailed instructions below.
+
+## Config Version
+
+The version field of the config file has been changed from `2` to `3`.
+
+## Hooks
+
+Since `1.8` both backup and restore hooks are possible.
+For this reason, backup hooks have been moved one layer deeper, you have to move them in a `backup` object.

+    from: /foo/bar
+    hooks:
