+ Enabled the lock-free stack implementation for aarch64 platforms.
+
+* **Extended pktmbuf mempool private structure.**
+
+ rte_pktmbuf_pool_private structure was extended to include flags field
+ for future compatibility.

+ by the user.
+
++* **Changed mempool allocation behavior.**
+
+ Changed the mempool allocation behaviour so that objects no longer cross
+ pages by default. Note, this may consume more memory when using small memory
+ pages.
+
+* **Added support for dynamic fields and flags in mbuf.**
+
+ This new feature adds the ability to dynamically register some room
+ for a field or a flag in the mbuf structure. This is typically used
+ for specific offload features, where adding a static field or flag
+ in the mbuf is not justified.
+
+* **Added support for hairpin queues.**

+
+ * Tx metadata can also be set by SET_META action of rte_flow.
+ * Rx metadata is delivered to the host via a dynamic field of ``rte_mbuf``
+ with ``PKT_RX_DYNF_METADATA``.
+
+* **Added ethdev API to set supported packet types.**
+
+ * Added new API ``rte_eth_dev_set_ptypes`` which allows an application to
+ inform a PMD about a reduced range of packet types to handle.
+ * This scheme will allow PMDs to avoid lookup of internal ptype table on Rx
+ and thereby improve Rx performance if the application wishes to do so.
+
+* **Added Rx offload flag to enable or disable RSS update.**
+
+ * Added new Rx offload flag ``DEV_RX_OFFLOAD_RSS_HASH`` which can be used to
+ enable/disable PMDs write to ``rte_mbuf::hash::rss``.
+ * PMDs notify the validity of ``rte_mbuf::hash:rss`` to the application
+ by enabling ``PKT_RX_RSS_HASH`` flag in ``rte_mbuf::ol_flags``.
+
+* **Added Rx/Tx packet burst mode "get" API.**
+
+ Added two new functions ``rte_eth_rx_burst_mode_get`` and
+ ``rte_eth_tx_burst_mode_get`` that allow an application
+ to retrieve the mode information about Rx/Tx packet burst
+ such as Scalar or Vector, and Vector technology like AVX2.

+ allocate and use memory zones as external buffers instead of keeping the
+ data directly in mbuf areas.
+
+* **Updated the IPSec library.**
+
+ * Added Security Associations (SA) Database API to ``librte_ipsec``. A new
+ test-sad application has also been introduced to evaluate and perform
+ custom functional and performance tests for an IPsec SAD implementation.

+ LTO is an optimization technique used by the compiler to perform whole
+ program analysis and optimization at link time. In order to do that
+ compilers store their internal representation of the source code that
+ the linker uses at the final stage of the compilation process.
+
+ See :doc:`../prog_guide/lto` for more information:
+
+* **Added IOVA as VA support for KNI.**
+
+ * Added IOVA = VA support for KNI. KNI can operate in IOVA = VA mode when
+ ``iova-mode=va`` EAL option is passed to the application or when bus IOVA
+ scheme is selected as RTE_IOVA_VA. This mode only works on Linux Kernel
+ versions >= 4.9.0.
+
+ * Due to IOVA to KVA address translations, based on the KNI use case there
+ can be a performance impact. For mitigation, forcing IOVA to PA via EAL
+ ``--iova-mode=pa`` option can be used, IOVA_DC bus iommu scheme can also
+ result in IOVA as PA.
+

API Changes
-----------
Also, make sure to start the actual text at the margin.
=========================================================
+* eal: made the ``lcore_config`` struct and global symbol private.
+
+* eal: removed the ``rte_cpu_check_supported`` function, replaced by
+ ``rte_cpu_is_supported`` since dpdk v17.08.
+
+* eal: removed the ``rte_malloc_virt2phy`` function, replaced by
+ ``rte_malloc_virt2iova`` since v17.11.
+
+* eal: made the ``rte_config`` struct and ``rte_eal_get_configuration``
+ function private.
+
+* mem: hid the internal ``malloc_heap`` structure and the
+ ``rte_malloc_heap.h`` header.
+
+* vfio: removed ``rte_vfio_dma_map`` and ``rte_vfio_dma_unmap`` that have
+ been marked as deprecated in release 19.05.
+ ``rte_vfio_container_dma_map`` and ``rte_vfio_container_dma_unmap`` can
+ be used as substitutes.
+
+* pci: removed the following functions deprecated since dpdk v17.11:
+
+ - ``eal_parse_pci_BDF`` replaced by ``rte_pci_addr_parse``
+ - ``eal_parse_pci_DomBDF`` replaced by ``rte_pci_addr_parse``
+ - ``rte_eal_compare_pci_addr`` replaced by ``rte_pci_addr_cmp``
+
+* The network structure ``esp_tail`` has been prefixed by ``rte_``.
+
+* The network definitions of PPPoE ethertypes have been prefixed by ``RTE_``.
+
+* The network structure for MPLS has been prefixed by ``rte_``.
+
* ethdev: changed ``rte_eth_dev_infos_get`` return value from ``void`` to
``int`` to provide a way to report various error conditions.
* ethdev: changed ``rte_eth_dev_owner_delete`` return value from ``void`` to
``int`` to provide a way to report various error conditions.
+* ethdev: The deprecated function ``rte_eth_dev_count`` was removed.
+ The function ``rte_eth_dev_count_avail`` is a drop-in replacement.
+ If the intent is to iterate over ports, ``RTE_ETH_FOREACH_*`` macros
+ are better port iterators.
+
+* ethdev: ``RTE_FLOW_ITEM_TYPE_META`` data endianness altered to host one.
+ Due to the new dynamic metadata field in mbuf is host-endian either, there
+ is a minor compatibility issue for applications in case of 32-bit values
+ supported.
+
+* ethdev: the tx_metadata mbuf field is moved to dynamic one.
+ ``PKT_TX_METADATA`` flag is replaced with ``PKT_TX_DYNF_METADATA``.
+ ``DEV_TX_OFFLOAD_MATCH_METADATA`` offload flag is removed, now metadata
+ support in PMD is engaged on dynamic field registration.
+
* event: The function ``rte_event_eth_tx_adapter_enqueue`` takes an additional
input as ``flags``. Flag ``RTE_EVENT_ETH_TX_ADAPTER_ENQUEUE_SAME_DEST`` which
has been introduced in this release is used when used when all the packets
- enqueued in the tx adapter are destined for the same Ethernet port & Tx queue.
+ enqueued in the Tx adapter are destined for the same Ethernet port ans Tx
+ queue.
+
+* sched: The pipe nodes configuration parameters such as number of pipes,
+ pipe queue sizes, pipe profiles, etc., are moved from port level structure
+ to subport level. This allows different subports of the same port to
+ have different configuration for the pipe nodes.
ABI Changes
Also, make sure to start the actual text at the margin.
=========================================================
+* policy: Please note the revisions to the :doc:`../contributing/abi_policy`
+ introducing major ABI versions, with DPDK 19.11 becoming the first major
+ version ``v20``. ABI changes to add new features continue to be permitted in
+ subsequent releases, with the condition that ABI compatibility with the major
+ ABI version is maintained.
+
+* net: The Ethernet address and other header definitions have changed
+ attributes. They have been modified to be aligned on 2-byte boundaries.
+ These changes should not impact normal usage because drivers naturally
+ align the Ethernet header on receive and all known encapsulations
+ preserve the alignment of the header.
+
+* security: The field ``replay_win_sz`` has been moved from the ipsec library
+ based ``rte_ipsec_sa_prm`` structure to security library based structure
+ ``rte_security_ipsec_xform``, which specify the anti-replay window size
+ to enable sequence replay attack handling.
+
+* ipsec: The field ``replay_win_sz`` has been removed from the structure
+ ``rte_ipsec_sa_prm`` as it has been added to the security library.
+
+* ethdev: Added 32-bit fields for maximum LRO aggregated packet size, in
+ struct ``rte_eth_dev_info`` for the port capability and in struct
+ ``rte_eth_rxmode`` for the port configuration.
+ Application should use the new field in struct ``rte_eth_rxmode`` to configure
+ the requested size.
+ PMD should use the new field in struct ``rte_eth_dev_info`` to report the
+ supported port capability.
