+## Any previous release → 1.4.0-alpha3
+
+We've made a small update to the LDAP integration to support more complex user nesting within the LDAP tree ([related issue](https://github.com/DefGuard/defguard/issues/1242)).
+
+If you were already using the integration, you shouldn't notice any changes. However, we **strongly recommend backing up your database before the upgrade and afterwards verifying** the following to ensure everything continues to work as expected:
+
+* Your Defguard user list and user devices remain unchanged
+* All users can still log in without issues
+
+If you encounter any problems, please report them on our [GitHub](https://github.com/DefGuard/defguard/issues).
+
 ## Any previous release → 1.3.0
 
 * The LDAP integration has became an enterprise feature. You will need to purchase the enterprise license if you exceed the free limits. See [license.md](../enterprise/license.md "mention") for more information regarding the license.

 To use this feature, your LDAP user entries must posses the "memberOf" attribute (or it's equivalent, defined using the member attribute), which may not be available by default on your LDAP server. This may require enabling an appropriate module.&#x20;
