The lock-free stack implementation is enabled for aarch64 platforms.
+* **Changed mempool allocation behaviour.**
+
+ Objects are no longer across pages by default.
+ It may consume more memory when using small memory pages.
+
+* **Added support of 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 hairpin queue.**
+
+ On supported NICs, we can now setup haipin queue which will offload packets
+ from the wire, backto the wire.
+
+* **Added flow tag in rte_flow.**
+
+ SET_TAG action and TAG item have been added to support transient flow tag.
+
+* **Extended metadata support in rte_flow.**
+
+ Flow metadata is extended to both Rx and Tx.
+
+ * Tx metadata can also be set by SET_META action of rte_flow.
+ * Rx metadata is delivered to host via a dynamic field of ``rte_mbuf`` with
+ PKT_RX_DYNF_METADATA.
+
+* **Updated the enic driver.**
+
+ * Added support for Geneve with options offload.
+ * Added flow API implementation based on VIC Flow Manager API.
+
* **Added Hisilicon hns3 PMD.**
Added the new ``hns3`` net driver for the inbuilt Hisilicon Network
Subsystem 3(HNS3) network engine found in the Hisilicon Kunpeng 920 SoC.
See the :doc:`../nics/hns3` guide for more details on this new driver.
+* **Added NXP PFE PMD.**
+
+ Added the new PFE driver for the NXP LS1012A platform. See the
+ :doc:`../nics/pfe` NIC driver guide for more details on this new driver.
+
+* **Updated iavf PMD.**
+
+ Enable AVX2 data path for iavf PMD.

+* **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.
+
* **Updated the Intel ice driver.**
Updated the Intel ice driver with new features and improvements, including:
* Added support for device-specific DDP package loading.
* Added support for handling Receive Flex Descriptor.

- Added SA Database API to ``librte_ipsec``. A new test-sad application is also
- introduced to evaluate and perform custom functional and performance tests
- for IPsec SAD implementation.
+ * Added SA Database API to ``librte_ipsec``. A new test-sad application is also
+ introduced to evaluate and perform custom functional and performance tests
+ for IPsec SAD implementation.
+
+ * Support fragmented packets in inline crypto processing mode with fallback
+ ``lookaside-none`` session. Corresponding changes are also added in IPsec
+ Security Gateway application.
* **Introduced FIFO for NTB PMD.**
Added eBPF JIT support for arm64 architecture to improve the eBPF program
performance.
+* **Added RIB and FIB (Routing/Forwarding Information Base) libraries.**
+
+ RIB and FIB can replace the LPM (Longest Prefix Match) library
+ with better control plane (RIB) performance.
+ The data plane (FIB) can be extended with new algorithms.
+
* **Updated testpmd.**
* Added a console command to testpmd app, ``show port (port_id) ptypes`` which
gives ability to print port supported ptypes in different protocol layers.
+* **Added new example l2fwd-event application.**
+
+ Added an example application `l2fwd-event` that adds event device support to
+ traditional l2fwd example. It demonstrates usage of poll and event mode IO
+ mechanism under a single application.
+
+* **Added build support for Link Time Optimization.**
+
+ 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 compilation process.
+
+ See :doc:`../prog_guide/lto` for more information:

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 the minor compatibility issue for applications in case of 32-bit values
+ supported.
+
+* ethdev: the tx_metadata mbuf field is moved to dymanic 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.
+* 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.
=========================================================
+* 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 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.
