=======================================================
+* **Added write combining store APIs.**
+
+ Added ``rte_write32_wc`` and ``rte_write32_wc_relaxed`` APIs
+ that enable write combining stores (depending on architecture).
+ The functions are provided as a generic stubs and
+ x86 specific implementation.
+
+* **Added prefetch with intention to write APIs.**
+
+ Added new prefetch function variants e.g. ``rte_prefetch0_write``,
+ which allow the programmer to prefetch a cache line and also indicate
+ the intention to write.
+
+* **Added the rte_cldemote API.**
+
+ Added a hardware hint CLDEMOTE, which is similar to prefetch in reverse.
+ CLDEMOTE moves the cache line to the more remote cache, where it expects
+ sharing to be efficient. Moving the cache line to a level more distant from
+ the processor helps to accelerate core-to-core communication.
+ This API is specific to x86 and implemented as a stub for other
+ architectures.
+
+* **Updated CRC modules of the net library.**
+
+ * Added runtime selection of the optimal architecture-specific CRC path.
+ * Added optimized implementations of CRC32-Ethernet and CRC16-CCITT
+ using the AVX512 and VPCLMULQDQ instruction sets.
+
+* **Added the FEC API, for a generic FEC query and config.**
+
+ Added the FEC API which provides functions for query FEC capabilities and
+ current FEC mode from device. Also, API for configuring FEC mode is also provided.
+
+* **Added thread safety to rte_flow functions.**
+
+ Added ``RTE_ETH_DEV_FLOW_OPS_THREAD_SAFE`` device flag to indicate
+ whether PMD supports thread safe operations. If PMD doesn't set the flag,
+ rte_flow API level functions will protect the flow operations with mutex.
+
+* **Added flow-based traffic sampling support.**
+
+ Added new action: ``RTE_FLOW_ACTION_TYPE_SAMPLE`` to duplicate the matching
+ packets with specified ratio, and apply with own set of actions with a fate
+ action. When the ratio is set to 1 then the packets will be 100% mirrored.

``--portmask=N``
where N represents the hexadecimal bitmask of ports used.
+* **Added raw data-path APIs for cryptodev library.**
+
+ Cryptodev is added with raw data-path APIs to accelerate external
+ libraries or applications which need to avail fast cryptodev
+ enqueue/dequeue operations but does not necessarily depends on

Removed Items
-------------
* ethdev: ``rte_eth_rx_descriptor_done()`` API has been deprecated.
-* Renamed internal ethdev APIs:
+* ethdev: Renamed basic statistics per queue. An underscore is inserted
+ between the queue number and the rest of the xstat name:
+
+ * ``rx_qN*`` -> ``rx_qN_*``
+ * ``tx_qN*`` -> ``tx_qN_*``
+
+* ethdev: Renamed internal functions:
* ``_rte_eth_dev_callback_process()`` -> ``rte_eth_dev_callback_process()``

+* ethdev: Modified field type of ``base`` and ``nb_queue`` in struct
+ ``rte_eth_dcb_tc_queue_mapping`` from ``uint8_t`` to ``uint16_t``.
+ As the data of ``uint8_t`` will be truncated when queue number under
+ a TC is greater than 256.
+
* vhost: Moved vDPA APIs from experimental to stable.
+* vhost: Add a new function ``rte_vhost_crypto_driver_start`` to be called
+ instead of ``rte_vhost_driver_start`` by crypto applications.
+
+* cryptodev: The structure ``rte_crypto_sym_vec`` is updated to support both
+ cpu_crypto synchrounous operation and asynchronous raw data-path APIs.
+
+* cryptodev: ``RTE_CRYPTO_AEAD_LIST_END`` from ``enum rte_crypto_aead_algorithm``,
+ ``RTE_CRYPTO_CIPHER_LIST_END`` from ``enum rte_crypto_cipher_algorithm`` and
+ ``RTE_CRYPTO_AUTH_LIST_END`` from ``enum rte_crypto_auth_algorithm``
+ are removed to avoid future ABI breakage while adding new algorithms.
+
+* scheduler: Renamed functions ``rte_cryptodev_scheduler_slave_attach``,
+ ``rte_cryptodev_scheduler_slave_detach`` and
+ ``rte_cryptodev_scheduler_slaves_get`` to
+ ``rte_cryptodev_scheduler_worker_attach``,
+ ``rte_cryptodev_scheduler_worker_detach`` and
+ ``rte_cryptodev_scheduler_workers_get`` accordingly.
+
+* scheduler: Renamed the configuration value
+ ``RTE_CRYPTODEV_SCHEDULER_MAX_NB_SLAVES`` to
+ ``RTE_CRYPTODEV_SCHEDULER_MAX_NB_WORKERS``.
+
+* security: ``hfn_ovrd`` field in ``rte_security_pdcp_xform`` is changed from
+ ``uint32_t`` to ``uint8_t`` so that a new field ``sdap_enabled`` can be added
+ to support SDAP.
+
+* ipsec: ``RTE_SATP_LOG2_NUM`` has been dropped from ``enum`` and
+ subsequently moved ``rte_ipsec`` lib from experimental to stable.
+
+* baseband/fpga_lte_fec: Renamed function ``fpga_lte_fec_configure`` to
+ ``rte_fpga_lte_fec_configure`` and structure ``fpga_lte_fec_conf`` to

* bpf: ``RTE_BPF_XTYPE_NUM`` has been dropped from ``rte_bpf_xtype``.
+* acl: ``RTE_ACL_CLASSIFY_NUM`` enum value has been removed.
+ This enum value was not used inside DPDK, while it prevented to add new
+ classify algorithms without causing an ABI breakage.

+* sched: Added ``subport_profile_id`` as argument
+ to function ``rte_sched_subport_config``.
+
+* sched: Removed ``tb_rate``, ``tc_rate``, ``tc_period`` and ``tb_size``
