 * metrics: The function ``rte_metrics_init`` will have a non-void return
   in order to notify errors instead of calling ``rte_exit``.
 
-* cmdline: ``cmdline`` structure will be made opaque to hide platform-specific
-  content. On Linux and FreeBSD, supported prior to DPDK 20.11,
-  original structure will be kept until DPDK 21.11.
-
 * security: The functions ``rte_security_set_pkt_metadata`` and
   ``rte_security_get_userdata`` will be made inline functions and additional
   flags will be added in structure ``rte_security_ctx`` in DPDK 21.11.
