=========================================================
+* **Added support for using externally allocated memory in DPDK.**
+
+ DPDK has gained support for creating new ``rte_malloc`` heaps referencing
+ memory that was created outside of DPDK's own page allocator, and using that
+ memory natively with any other DPDK library or data structure.
+
+* **Added hot-unplug handle mechanism.**
+
+ ``rte_dev_hotplug_handle_enable`` and ``rte_dev_hotplug_handle_disable`` are
+ for enabling or disabling hotplug handle mechanism.
+
+* **Support device multi-process hotplug.**
+
+ Hotplug and hot-unplug for devices will now be supported in multiprocessing
+ scenario. Any ethdev devices created in the primary process will be regarded
+ as shared and will be available for all DPDK processes. Synchronization
+ between processes will be done using DPDK IPC.
+
+* **Added new Flow API actions to rewrite fields in packet headers.**
+

+ * Action items: push/pop/rewrite vlan header,
+ rewrite IP addresses in outermost IPv4/IPv6 header,
+ rewrite port numbers in outermost TCP/UDP header,
+ swap MAC addresses in outermost Ethernet header.
+
+* **Added a devarg to use the latest supported vector path in i40e.**
+ A new devarg ``use-latest-supported-vec`` was introduced to allow users to
+ choose the latest vector path that the platform supported. For example, users
+ can use AVX2 vector path on BDW/HSW to get better performance.
* **Added support for SR-IOV in netvsc PMD.**
SR-IOV option in Hyper-V and Azure. This is an alternative to the previous
vdev_netvsc, tap, and failsafe drivers combination.
+* **Added a new net driver for Marvell Armada 3k device.**
+
+ Added the new ``mvneta`` net driver for Marvell Armada 3k device. See the
+ :doc:`../nics/mvneta` NIC guide for more details on this new driver.
+
+* **Added NXP ENETC PMD.**
+
+ Added the new enetc driver for NXP enetc platform. See the
+ "ENETC Poll Mode Driver" document for more details on this new driver.
+
+* **Added Ethernet poll mode driver for Aquantia aQtion family of 10G devices.**

+ * Added support for Tx descriptor status API in EF10 (ef10 and ef10_simple)
+ datapaths implementation.
+
+* **Updated failsafe driver.**
+
+ Updated the failsafe driver including the following changes:
+
+ * Support for Rx and Tx queues start and stop.
+ * Support for Rx and Tx queues deferred start.
+ * Support for runtime Rx and Tx queues setup.
+ * Support multicast MAC address set.
+
+* **Added a devarg to use PCAP interface physical MAC address.**
+ A new devarg ``phy_mac`` was introduced to allow users to use physical
+ MAC address of the selected PCAP interface.
+
+* **Added support for GEN3 devices to Intel QAT driver .**
+
+ Added support for the third generation of Intel QuickAssist devices.
+
+* **Updated the QAT PMD.**
+
+ The QAT PMD was updated with additional support for:
+

+ Added the new caam job ring driver for NXP platforms. See the
+ "NXP CAAM JOB RING (caam_jr)" document for more details on this new driver.
+
+* **Added Event Ethernet Tx Adapter.**
+
+ Added event ethernet Tx adapter library that provides configuration and
+ data path APIs for the ethernet transmit stage of an event driven packet
+ processing application. These APIs abstract the implementation of the
+ transmit stage and allow the application to use eventdev PMD support or
+ a common implementation.
+
+* **Added Distributed Software Eventdev PMD.**
+
+ Added the new Distributed Software Event Device (DSW), which is a
+ pure-software eventdev driver distributing the work of scheduling
+ among all eventdev ports and the lcores using them. DSW, compared to
+ the SW eventdev PMD, sacrifices load balancing performance to
+ gain better event scheduling throughput and scalability.
+
+* **Added extendable bucket feature to hash library (rte_hash).**
+
+ This new “extendable bucket” feature provides 100% insertion guarantee to
+ the capacity specified by the user by extending hash table with extra
+ buckets when needed to accommodate the unlikely event of intensive hash
+ collisions. In addition, the internal hashing algorithm was changed to use
+ partial-key hashing to improve memory efficiency and lookup performance.
+
+* **Added Traffic Pattern Aware Power Control Library**
+
+ Added an experimental library. This extend Power Library and provide
+ empty_poll APIs. This feature measure how many times empty_poll are
+ executed per core, use the number of empty polls as a hint for system
+ power management.
+
+ See the :doc:`../prog_guide/power_man` section of the DPDK Programmers
+ Guide document for more information.
+
+* **Added JSON power policy interface for containers.**
+
+ Extended the Power Library and vm_power_manager sample app to allow power
+ policies to be submitted via a FIFO using JSON formatted strings. Previously
+ limited to Virtual Machines, this feature extends power policy functionality
+ to containers and host applications that need to have their cores frequency
+ controlled based on the rules contained in the policy.
+
+* **Added ability to switch queue deferred start flag on testpmd app.**
+
+ Added a console command to testpmd app, giving ability to switch
+ ``rx_deferred_start`` or ``tx_deferred_start`` flag of the specified queue of
+ the specified port. The port must be stopped before the command call in order
+ to reconfigure queues.
+
+* **Add a new sample for vDPA**
+
+ The vdpa sample application creates vhost-user sockets by using the
+ vDPA backend. vDPA stands for vhost Data Path Acceleration which utilizes
+ virtio ring compatible devices to serve virtio driver directly to enable
+ datapath acceleration. As vDPA driver can help to set up vhost datapath,
+ this application doesn't need to launch dedicated worker threads for vhost
+ enqueue/dequeue operations.
+
API Changes
-----------
Also, make sure to start the actual text at the margin.
=========================================================
+* eal: ``rte_memseg_list`` structure now has an additional flag indicating
+ whether the memseg list is externally allocated. This will have implications
+ for any users of memseg-walk-related functions, as they will now have to skip
+ externally allocated segments in most cases if the intent is to only iterate
+ over internal DPDK memory.
+ ``socket_id`` parameter across the entire DPDK has gained additional meaning,
+ as some socket ID's will now be representing externally allocated memory. No
+ changes will be required for existing code as backwards compatibility will be
+ kept, and those who do not use this feature will not see these extra socket
+ ID's. Any new API's must not check socket ID parameters themselves, and must
+ instead leave it to the memory subsystem to decide whether socket ID is a
+ valid one.
+
+* eal: The following devargs functions, which were deprecated in 18.05,
+ were removed in 18.11:
+ ``rte_eal_parse_devargs_str()``, ``rte_eal_devargs_add()``,
+ ``rte_eal_devargs_type_count()``, and ``rte_eal_devargs_dump()``.
+
+* eal: The parameters of the function ``rte_devargs_remove()`` have changed
+ from bus and device names to ``struct rte_devargs``.
+
+* eal: The scope of ``rte_eal_hotplug_add()``/``rte_dev_probe()``
+ and ``rte_eal_hotplug_remove()``/``rte_dev_remove()`` is extended.
+ In multi-process model, they will guarantee that the device is
+ attached or detached on all processes.
+
* mbuf: The ``__rte_mbuf_raw_free()`` and ``__rte_pktmbuf_prefree_seg()``
functions were deprecated since 17.05 and are replaced by
``rte_mbuf_raw_free()`` and ``rte_pktmbuf_prefree_seg()``.
flag the MAC can be properly configured in any case. This is particularly
important for bonding.
+* The default behaviour of CRC strip offload changed. Without any specific Rx
+ offload flag, default behavior by PMD is now to strip CRC.
+ DEV_RX_OFFLOAD_CRC_STRIP offload flag has been removed.
+ To request keeping CRC, application should set ``DEV_RX_OFFLOAD_KEEP_CRC`` Rx
+ offload.
+
+* eventdev: Type of 2nd parameter to ``rte_event_eth_rx_adapter_caps_get()``
+ has been changed from uint8_t to uint16_t.
+
ABI Changes
-----------
Also, make sure to start the actual text at the margin.
=========================================================
+* eal: added ``legacy_mem`` and ``single_file_segments`` values to
+ ``rte_config`` structure on account of improving DPDK usability when
+ using either ``--legacy-mem`` or ``--single-file-segments`` flags.
+
+* eal: EAL library ABI version was changed due to previously announced work on
+ supporting external memory in DPDK:
+ - structure ``rte_memseg_list`` now has a new field indicating length
+ of memory addressed by the segment list
+ - structure ``rte_memseg_list`` now has a new flag indicating whether
+ the memseg list refers to external memory
+ - structure ``rte_malloc_heap`` now has a new field indicating socket
+ ID the malloc heap belongs to
+ - structure ``rte_mem_config`` has had its ``malloc_heaps`` array
+ resized from ``RTE_MAX_NUMA_NODES`` to ``RTE_MAX_HEAPS`` value
+ - structure ``rte_malloc_heap`` now has a ``heap_name`` member
+ - structure ``rte_eal_memconfig`` has been extended to contain next
+ socket ID for externally allocated segments
+
+* eal: The structure ``rte_device`` got a new field to reference a ``rte_bus``.
+ It is changing the size of the ``struct rte_device`` and the inherited
+ device structures of all buses.
