   Added ``rte_eth_get_monitor_addr()``, to be used in conjunction with

+  A new helper API has been added to make using Ethernet PMD power management
+  easier for the user: ``rte_power_ethdev_pmgmt_queue_enable()``. Three power
+  management schemes are supported initially:
+
+  * Power saving based on UMWAIT instruction (x86 only)
+  * Power saving based on ``rte_pause()`` (generic) or TPAUSE instruction (x86 only)
+  * Power saving based on frequency scaling through the ``librte_power`` library

 * **Added GENEVE TLV option in rte_flow.**
 
   Added support for matching and raw encap/decap of GENEVE TLV option.

    =======================================================
 
+* config: Removed the old macros, included in ``rte_config.h``,
+  to indicate which DPDK libraries and drivers are built.
+  The new macros are generated by meson in a standardized format:
+  ``RTE_LIB_<NAME>`` and ``RTE_<CLASS>_<NAME>``, where ``NAME`` is
+  the upper-case component name, e.g. ``EAL``, ``ETHDEV``, ``VIRTIO``,
+  and ``CLASS`` is the upper-case driver class, e.g. ``NET``, ``CRYPTO``.
+
 * cryptodev: The structure ``rte_cryptodev`` has been updated with pointers
   for adding enqueue and dequeue callbacks.
