   us extending existing enum/define.
   One solution can be using a fixed size array instead of ``.*MAX.*`` value.
 
-* mbuf: Some fields will be converted to dynamic API in DPDK 20.11
-  in order to reserve more space for the dynamic fields, as explained in
-  `this presentation <https://www.youtube.com/watch?v=Ttl6MlhmzWY>`_.
-  As a consequence, the layout of the ``struct rte_mbuf`` will be re-arranged,
-  avoiding impact on vectorized implementation of the driver datapaths,
-  while evaluating performance gains of a better use of the first cache line.
-
 * ethdev: The flow director API, including ``rte_eth_conf.fdir_conf`` field,
   and the related structures (``rte_fdir_*`` and ``rte_eth_fdir_*``),
   will be removed in DPDK 20.11.
