=========================================================
+* **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 check for ensuring allocated memory addressable by devices.**
+
+ Some devices can have addressing limitations so a new function,
+ ``rte_mem_check_dma_mask``, has been added for checking allocated memory is
+ not out of the device range. Because now memory can be dynamically allocated
+ after initialization, a dma mask is kept and any new allocated memory will be
+ checked out against that dma mask and rejected if out of range. If more than
+ one device has addressing limitations, the dma mask is the more restricted one.
+
+* **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.**
+
+ Added new Flow API actions to:
+
+ * Modify source and destination IP addresses in the outermost IPv4/IPv6
+ headers.
+ * Modify source and destination port numbers in the outermost TCP/UDP
+ headers.
+
+* **Added new Flow API action to swap MAC addresses in Ethernet header.**
+
+ Added new Flow API action to swap the source and destination MAC
+ addresses in the outermost Ethernet header.
+
* **Add support to offload more flow match and actions for CXGBE PMD**
Flow API support has been enhanced for CXGBE Poll Mode Driver to offload:
- * Action items: push/pop/rewrite vlan header.
+ * Match items: destination MAC address.
+ * 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.**
+
+ The ``netvsc`` poll mode driver now supports the Accelerated Networking
+ 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 support for Rx descriptor status API in EF10 datapath implementation.
+ * Added support for TSO in EF10 datapath implementation.
+ * Added support for Tx descriptor status API in EF10 (ef10 and ef10_simple)
+ datapaths implementation.
+
+* **Updated the enic driver.**
+
+ * Added AVX2-based vectorized Rx handler.
+ * Added VLAN and checksum offloads to the simple Tx handler.
+ * Added the count flow action.
+ * Enabled the virtual address IOVA mode.
+
+* **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 TAP Rx/Tx queues sharing with a secondary process.**
+
+ A secondary process can attach a TAP device created in the primary process,
+ probe the queues, and process Rx/Tx in a secondary process.
+
+* **Added classification and metering support to SoftNIC PMD.**
+
+ Added support for flow classification (rte_flow API), and metering and
+ policing (rte_mtr API) to the SoftNIC PMD.
+
+* **Added Crypto support to Softnic PMD.**
+
+ The Softnic is now capable of processing symmetric crypto workloads such
+ as cipher, cipher-authentication chaining, and aead encryption and
+ decryption. This is achieved by calling DPDK Cryptodev APIs.
+
+* **Added cryptodev port to port library.**
+
+ Cryptodev port is a shim layer in the port library that interacts with DPDK
+ Cryptodev PMDs including burst enqueuing and dequeuing crypto operations.
+
+* **Added symmetric cryptographic actions to the pipeline library.**
+
+ In the pipeline library an added symmetric crypto action parsing and action
+ handler are implemented. The action allows automatically preparing the crypto
+ operation with the rules specified such as algorithm, key, and IV, etc for
+ the cryptodev port to process.
+
+* **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:
+
+ * AES-CMAC algorithm.
+
+* **Updated the AESNI MB PMD.**
+
+ The AESNI MB PMD has been updated with additional support for AES-GCM
+ algorithm support.
+
+* **Added NXP CAAM JR PMD.**
+
+ 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 support for Dynamic Huffman Encoding to Intel QAT comp PMD.**
+
+ The Intel QuickAssist (QAT) compression PMD has been updated with support
+ for Dynamic Huffman Encoding for the Deflate algorithm.
+
+* **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 lock free reader/writer concurrency to hash library (rte_hash).**
+
+ Lock free reader/writer concurrency prevents the readers from getting
+ blocked due to a pre-empted writer thread. This allows the hash library
+ to be used in scenarios where the writer thread runs on control plane.
+
+* **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 Telemetry API.**
+
+ Added the telemetry API which allows applications to transparently expose
+ their telemetry via a UNIX socket in JSON. The JSON can be consumed by any
+ Service Assurance agent, such as CollectD.
+
+* **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.
+
+* **Added cryptodev FIPS validation example application.**
+
+ Added an example application to parse and perform symmetric cryptography
+ computation to the NIST Cryptographic Algorithm Validation Program (CAVP)
+ test vectors.
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 deprecated functions attach/detach were removed in 18.11.
+ ``rte_eal_dev_attach`` can be replaced by
+ ``rte_dev_probe`` or ``rte_eal_hotplug_add``.
+ ``rte_eal_dev_detach`` can be replaced by
+ ``rte_dev_remove`` or ``rte_eal_hotplug_remove``.
+
+* 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()``.
+
+* ethdev: The deprecated functions attach/detach were removed in 18.11.
+ ``rte_eth_dev_attach`` can be replaced by ``RTE_ETH_FOREACH_MATCHING_DEV``
+ and ``rte_dev_probe`` or ``rte_eal_hotplug_add``.
+ ``rte_eth_dev_detach`` can be replaced by
+ ``rte_dev_remove`` or ``rte_eal_hotplug_remove``.
+
+* ethdev: A call to ``rte_eth_dev_release_port()`` has been added in
+ ``rte_eth_dev_close()``. As a consequence, a closed port is freed
+ and seen as invalid because of its state ``RTE_ETH_DEV_UNUSED``.
+ This new behaviour is enabled per driver for a migration period.
+
* A new device flag, RTE_ETH_DEV_NOLIVE_MAC_ADDR, changes the order of
actions inside rte_eth_dev_start regarding MAC set. Some NICs do not
support MAC changes once the port has started and with this new device
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: Added ``dma_maskbits`` to ``rte_mem_config`` for keeping more restricted
+ dma mask based on devices addressing limitations.
+
+* 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.
