+* eal: The semantics of the return value for the ``rte_lcore_has_role`` function
+ are planned to change in v18.05. The function currently returns 0 and <0 for
+ success and failure, respectively. This will change to 1 and 0 for true and
+ false, respectively, to make use of the function more intuitive.
+
+* eal: new ``numa_node_count`` member will be added to ``rte_config`` structure
+ in v18.05.
+
+* eal: due to internal data layout reorganization, there will be changes to
+ several structures and functions as a result of coming changes to support
+ memory hotplug in v18.05.
+ ``rte_eal_get_physmem_layout`` will be deprecated and removed in subsequent
+ releases.
+ ``rte_mem_config`` contents will change due to switch to memseg lists.
+ ``rte_memzone`` member ``memseg_id`` will no longer serve any useful purpose
+ and will be removed.
+
+* eal: a new set of mbuf mempool ops name APIs for user, platform and best
+ mempool names have been defined in ``rte_mbuf`` in v18.02. The uses of
+ ``rte_eal_mbuf_default_mempool_ops`` shall be replaced by
+ ``rte_mbuf_best_mempool_ops``.
+ The following function is now redundant and it is target to be deprecated
+ in 18.05:
+
+ - ``rte_eal_mbuf_default_mempool_ops``
+
+* mempool: several API and ABI changes are planned in v18.05.
+ The following functions, introduced for Xen, which is not supported
+ anymore since v17.11, are hard to use, not used anywhere else in DPDK.
+ Therefore they will be deprecated in v18.05 and removed in v18.08:
+
+ - ``rte_mempool_xmem_create``
+ - ``rte_mempool_xmem_size``
+ - ``rte_mempool_xmem_usage``
+
+ The following changes are planned:
+
+ - removal of ``get_capabilities`` mempool ops and related flags.
+ - substitute ``register_memory_area`` with ``populate`` ops.
+ - addition of new ops to customize required memory chunk calculation,
+ customize objects population and allocate contiguous
+ block of objects if underlying driver supports it.
+
+* mbuf: The control mbuf API will be removed in v18.05. The impacted
+ functions and macros are:
+
+ - ``rte_ctrlmbuf_init()``
+ - ``rte_ctrlmbuf_alloc()``
+ - ``rte_ctrlmbuf_free()``
+ - ``rte_ctrlmbuf_data()``
+ - ``rte_ctrlmbuf_len()``
+ - ``rte_is_ctrlmbuf()``
+ - ``CTRL_MBUF_FLAG``
+
+ The packet mbuf API should be used as a replacement.
+
+* mbuf: The opaque ``mbuf->hash.sched`` field will be updated to support generic
+ definition in line with the ethdev TM and MTR APIs. Currently, this field
+ is defined in librte_sched in a non-generic way. The new generic format
+ will contain: queue ID, traffic class, color. Field size will not change.
