+* cmdline: ``cmdline_stdin_exit()`` now frees the ``cmdline`` structure.
+ Calls to ``cmdline_free()`` after it need to be deleted from applications.
+
+* cmdline: Made ``cmdline`` structure definition hidden on Linux and FreeBSD.
+
+* cmdline: Made ``rdline`` structure definition hidden. Functions are added
+ to dynamically allocate and free it, and to access user data in callbacks.
+
+* mempool: Added ``RTE_MEMPOOL_F_NON_IO`` flag to give a hint to DPDK components
+ that objects from this pool will not be used for device IO (e.g. DMA).
+
+* mempool: The mempool flags ``MEMPOOL_F_*`` will be deprecated in the future.
+ Newly added flags with ``RTE_MEMPOOL_F_`` prefix should be used instead.
+
+* mempool: Helper macro ``MEMPOOL_HEADER_SIZE()`` is deprecated.
+ The replacement macro ``RTE_MEMPOOL_HEADER_SIZE()`` is internal only.
+
+* mempool: Macro to register mempool driver ``MEMPOOL_REGISTER_OPS()`` is
+ deprecated. Use replacement ``RTE_MEMPOOL_REGISTER_OPS()``.
+
+* mempool: The mempool API macros ``MEMPOOL_PG_*`` are deprecated and
+ will be removed in DPDK 22.11.
+
+* net: Renamed ``s_addr`` and ``d_addr`` fields of ``rte_ether_hdr`` structure
+ to ``src_addr`` and ``dst_addr``, respectively.
+
+* net: Added ``version`` and ``ihl`` bit-fields to ``struct rte_ipv4_hdr``.
+ Existing ``version_ihl`` field is kept for backward compatibility.
+
+* ethdev: Added items and actions ``PORT_REPRESENTOR``, ``REPRESENTED_PORT`` to
+ flow API.
+
+* ethdev: Deprecated items and actions ``PF``, ``VF``, ``PHY_PORT``, ``PORT_ID``.
+ Suggested items and actions ``PORT_REPRESENTOR``, ``REPRESENTED_PORT`` instead.
+
+* ethdev: Deprecated the use of attributes ``ingress`` / ``egress`` combined
+ with ``transfer``. See items ``PORT_REPRESENTOR``, ``REPRESENTED_PORT``.
+
+* ethdev: ``rte_flow_action_modify_data`` structure updated, immediate data
+ array is extended, data pointer field is explicitly added to union, the
+ action behavior is defined in more strict fashion and documentation updated.
+ The immediate value behavior has been changed, the entire immediate field
+ should be provided, and offset for immediate source bitfield is assigned
+ from destination one.
