+  component: BDR
+  component_version: 5.6.1
+  details: |
+    Some DDL commands can be safe in situations PGD does not allow them yet. For example rewriting
+    ALTER TABLE that only does immutable conversions. The `bdr.permit_unsafe_commands` now allows user
+    to override the safety check and execute the command anyway, if they are know the command is safe.
