+### MariaDB Client Compatibility
+
+MariaDB client tools require different versions depending on the server:
+
+**Legacy client (10.6)** - Required for:
+
+- MariaDB 5.5
+- MariaDB 10.1
+
+**Modern client (12.1)** - Works with:

+- MariaDB 10.11
+- MariaDB 11.4, 11.8
+- MariaDB 12.0
+
+The reason is that MariaDB 12.1 client uses SQL queries referencing the `generation_expression` column in `information_schema.columns`, which was added in MariaDB 10.2. The application automatically selects the appropriate client version based on the target server version.
