+3. Command `openstack security group rule delete` now requires rule id
+
+  Previously, the command was `openstack security group rule delete --proto
+  <proto> [--src-ip <ip-address> --dst-port <port-range>] <group>`,
+  whereas now it is: `openstack security group rule delete <rule>`.
+
+  * In favor of: Using `openstack security group rule delete <rule>`.
+  * As of: 1.2.1
+  * Removed in: NA
