=========================================================
+* **Added bucket mempool driver.**
+
+ Added bucket mempool driver which provides a way to allocate contiguous
+ block of objects.
+ Number of objects in the block depends on how many objects fit in
+ RTE_DRIVER_MEMPOOL_BUCKET_SIZE_KB memory chunk which is build time option.
+ The number may be obtained using rte_mempool_ops_get_info() API.
+ Contiguous blocks may be allocated using rte_mempool_get_contig_blocks() API.
+
* **Added PMD-recommended Tx and Rx parameters**
Applications can now query drivers for device-tuned values of
* Added support for Solarflare XtremeScale X2xxx family adapters.
* Added support for NVGRE, VXLAN and GENEVE filters in flow API.
* Added support for DROP action in flow API.
+ * Added support for equal stride super-buffer Rx mode (X2xxx only).
+ * Added support for MARK and FLAG actions in flow API (X2xxx only).
* **Added Ethernet poll mode driver for AMD XGBE devices.**
See the :doc:`../nics/axgbe` nic driver guide for more details on this
new driver.
+* **Updated szedata2 PMD.**
+
+ Added support for new NFB-200G2QL card.
+ New API was introduced in the libsze2 library which the szedata2 PMD depends
+ on thus the new version of the library was needed.
+ New versions of the packages are available and the minimum required version
+ is 4.4.1.
+
+* **Added support for Broadcom NetXtreme-S (BCM58800) family of controllers (aka Stingray)**
+
+ The BCM58800 devices feature a NetXtreme E-Series advanced network controller, a high-performance
+ ARM CPU block, PCI Express (PCIe) Gen3 interfaces, key accelerators for compute offload and a high-
+ speed memory subsystem including L3 cache and DDR4 interfaces, all interconnected by a coherent
+ Network-on-chip (NOC) fabric.
+
+ The ARM CPU subsystem features eight ARMv8 Cortex-A72 CPUs at 3.0 GHz, arranged in a multi-cluster
+ configuration.
+
+* **Added IFCVF vDPA driver.**
+
+ Added IFCVF vDPA driver to support Intel FPGA 100G VF device. IFCVF works
+ as a HW vhost data path accelerator, it supports live migration and is
+ compatible with virtio 0.95 and 1.0. This driver registers ifcvf vDPA driver
+ to vhost lib, when virtio connected, with the help of the registered vDPA
+ driver the assigned VF gets configured to Rx/Tx directly to VM's virtio
+ vrings.
+
+* **Added support for virtio-user server mode.**
+ In a container environment if the vhost-user backend restarts, there's no way
+ for it to reconnect to virtio-user. To address this, support for server mode
+ is added. In this mode the socket file is created by virtio-user, which the
+ backend connects to. This means that if the backend restarts, it can reconnect
+ to virtio-user and continue communications.
+
* **Added crypto workload support to vhost library.**
New APIs are introduced in vhost library to enable virtio crypto support
including session creation/deletion handling and translating virtio-crypto
request into DPDK crypto operations. A sample application is also introduced.
+* **Added virtio crypto PMD.**
+
+ Added a new poll mode driver for virtio crypto devices, which provides
+ AES-CBC ciphering and AES-CBC with HMAC-SHA1 algorithm-chaining. See the
+ :doc:`../cryptodevs/virtio` crypto driver guide for more details on
+ this new driver.
+
+* **Added AMD CCP Crypto PMD.**

+ The compressdev library provides an API for offload of compression and
+ decompression operations to hardware or software accelerator devices.
+
+* **Added a new compression poll mode driver using Intels ISA-L.**
+
+ Added the new ``ISA-L`` compression driver, for compression and decompression
+ operations in software. See the :doc:`../compressdevs/isal` compression driver
+ guide for details on this new driver.
+
+* **Added the Event Timer Adapter Library.**
+
+ The Event Timer Adapter Library extends the event-based model by introducing
+ APIs that allow applications to arm/cancel event timers that generate
+ timer expiry events. This new type of event is scheduled by an event device
+ along with existing types of events.
+
+* **Added OcteonTx TIM Driver (Event timer adapter).**
+
+ The OcteonTx Timer block enables software to schedule events for a future
+ time, it is exposed to an application via Event timer adapter library.
+
+ See the :doc:`../eventdevs/octeontx` guide for more details
+
+* **Added Event Crypto Adapter Library.**
+
+ Added the Event Crypto Adapter Library. This library extends the
+ event-based model by introducing APIs that allow applications to
+ enqueue/dequeue crypto operations to/from cryptodev as events scheduled
+ by an event device.
+
+* **Added Ifpga Bus, a generic Intel FPGA Bus library.**
+
+ The Ifpga Bus library provides support for integrating any Intel FPGA device with
+ the DPDK framework. It provides Intel FPGA Partial Bit Stream AFU (Accelerated
+ Function Unit) scan and drivers probe.
+
+* **Added IFPGA (Intel FPGA) Rawdev Driver.**
+
+ Added a new Rawdev driver called IFPGA(Intel FPGA) Rawdev Driver, which cooperates
+ with OPAE (Open Programmable Acceleration Engine) share code provides common FPGA
+ management ops for FPGA operation.
+
+ See the :doc:`../rawdevs/ifpga_rawdev` programmer's guide for more details.
+
+* **Added DPAA2 QDMA Driver (in rawdev).**
+
+ The DPAA2 QDMA is an implementation of the rawdev API, that provide means
+ to initiate a DMA transaction from CPU. The initiated DMA is performed
+ without CPU being involved in the actual DMA transaction.
+
+ See the :doc:`../rawdevs/dpaa2_qdma` guide for more details.
+
+* **Added DPAA2 Command Interface Driver (in rawdev).**
+
+ The DPAA2 CMDIF is an implementation of the rawdev API, that provides
+ communication between the GPP and NXP's QorIQ based AIOP Block (Firmware).
+ Advanced IO Processor i.e. AIOP is clusters of programmable RISC engines
+ optimised for flexible networking and I/O operations. The communication
+ between GPP and AIOP is achieved via using DPCI devices exposed by MC for
+ GPP <--> AIOP interaction.
+
+ See the :doc:`../rawdevs/dpaa2_cmdif` guide for more details.
+
* **Added device event monitor framework.**
Added a general device event monitor framework at EAL, for device dynamic management.
Linux uevent is supported as backend of this device event notification framework.
+* **Added support for procinfo and pdump on eth vdev.**
+
+ For ethernet virtual devices (like tap, pcap, etc), with this feature, we can get
+ stats/xstats on shared memory from secondary process, and also pdump packets on
+ those virtual devices.
+
+* **Added the BPF Library.**
+
+ The BPF Library provides the ability to load and execute
+ Enhanced Berkeley Packet Filter (eBPF) within user-space dpdk application.
+ It also adds dependency on libelf.

API Changes
-----------
Also, make sure to start the actual text at the margin.
=========================================================
+* service cores: no longer marked as experimental.
+
+ The service cores functions are no longer marked as experimental, and have
+ become part of the normal DPDK API and ABI. Any future ABI changes will be
+ announced at least one release before the ABI change is made. There are no
+ ABI breaking changes planned.
+
+* eal: ``rte_lcore_has_role()`` return value changed.
+
+ This function now returns true or false, respectively,
+ rather than 0 or <0 for success or failure.
+ It makes use of the function more intuitive.
+
+* mempool: capability flags and related functions have been removed.
+
+ Flags ``MEMPOOL_F_CAPA_PHYS_CONTIG`` and
+ ``MEMPOOL_F_CAPA_BLK_ALIGNED_OBJECTS`` were used by octeontx mempool
+ driver to customize generic mempool library behaviour.
+ Now the new driver callbacks ``calc_mem_size`` and ``populate`` may be
+ used to achieve it without specific knowledge in the generic code.
+
+* mempool: xmem functions have been deprecated:
+
+ - ``rte_mempool_xmem_create``
+ - ``rte_mempool_xmem_size``
+ - ``rte_mempool_xmem_usage``
+ - ``rte_mempool_populate_iova_tab``
+
* mbuf: The control mbuf API has been removed in v18.05. The impacted
functions and macros are:
memory footprint which helps in better cache utilization when large number
of meter objects are used.
+* ethdev: The function ``rte_eth_dev_count``, often mis-used to iterate
+ over ports, is deprecated and replaced by ``rte_eth_dev_count_avail``.
+ There is also a new function ``rte_eth_dev_count_total`` to get the
+ total number of allocated ports, available or not.
+ The hotplug-proof applications should use ``RTE_ETH_FOREACH_DEV`` or
+ ``RTE_ETH_FOREACH_DEV_OWNED_BY`` as port iterators.
+
* ethdev, in struct ``struct rte_eth_dev_info``, field ``rte_pci_device *pci_dev``
replaced with field ``struct rte_device *device``.
fall-back value. Previously, setting ``nb_tx_desc`` to zero would have
resulted in an error.
+* ethdev: several changes were made to the flow API.
+
+ * Unused DUP action was removed.
+ * Actions semantics in flow rules: list order now matters ("first
+ to last" instead of "all simultaneously"), repeated actions are now
+ all performed, and they do not individually have (non-)terminating
+ properties anymore.
+ * Flow rules are now always terminating unless a PASSTHRU action is
+ present.
+ * C99-style flexible arrays were replaced with standard pointers in RSS
+ action and in RAW pattern item structures due to compatibility issues.
+ * The RSS action was modified to not rely on external
+ ``struct rte_eth_rss_conf`` anymore to instead expose its own and more
+ appropriately named configuration fields directly
+ (``rss_conf->rss_key`` => ``key``,
+ ``rss_conf->rss_key_len`` => ``key_len``,
+ ``rss_conf->rss_hf`` => ``types``,
+ ``num`` => ``queue_num``), and the addition of missing RSS parameters
+ (``func`` for RSS hash function to apply and ``level`` for the
+ encapsulation level).
+ * The VLAN pattern item (``struct rte_flow_item_vlan``) was modified to
+ include inner EtherType instead of outer TPID. Its default mask was also
+ modified to cover the VID part (lower 12 bits) of TCI only.
+ * A new transfer attribute was added to ``struct rte_flow_attr`` in order
+ to clarify the behavior of some pattern items.
+ * PF and VF pattern items are now only accepted by PMDs that implement
+ them (bnxt and i40e) when the transfer attribute is also present for
+ consistency.
+ * Pattern item PORT was renamed PHY_PORT to avoid confusion with DPDK port
+ IDs.
+ * An action counterpart to the PHY_PORT pattern item was added in order to
+ redirect matching traffic to a specific physical port.
+ * PORT_ID pattern item and actions were added to match and target DPDK
+ port IDs at a higher level than PHY_PORT.
+
+* ethdev: change flow APIs regarding count action:
+ * ``rte_flow_create()`` API count action now requires the ``struct rte_flow_action_count``.
+ * ``rte_flow_query()`` API parameter changed from action type to action structure.
+
ABI Changes
-----------
Also, make sure to start the actual text at the margin.
=========================================================
+* ring: the alignment constraints on the ring structure has been relaxed
+ to one cache line instead of two, and an empty cache line padding is
+ added between the producer and consumer structures. The size of the
+ structure and the offset of the fields remains the same on platforms
+ with 64B cache line, but change on other platforms.
+
+* mempool: ops have changed.
+
+ A new callback ``calc_mem_size`` has been added to ``rte_mempool_ops``
+ to allow to customize required memory size calculation.
+ A new callback ``populate`` has been added to ``rte_mempool_ops``
+ to allow to customize objects population.
+ Callback ``get_capabilities`` has been removed from ``rte_mempool_ops``
+ since its features are covered by ``calc_mem_size`` and ``populate``
+ callbacks.
+ Callback ``register_memory_area`` has been removed from ``rte_mempool_ops``
+ since the new callback ``populate`` may be used instead of it.
+
* **Additional fields in rte_eth_dev_info.**
The ``rte_eth_dev_info`` structure has had two extra entries appended to the
type ``uint16_t``: ``burst_size``, ``ring_size``, and ``nb_queues``. These
are parameter values recommended for use by the PMD.
+* ethdev: ABI for all flow API functions was updated.
+
+ This includes functions ``rte_flow_copy``, ``rte_flow_create``,
+ ``rte_flow_destroy``, ``rte_flow_error_set``, ``rte_flow_flush``,
+ ``rte_flow_isolate``, ``rte_flow_query`` and ``rte_flow_validate``, due to
+ changes in error type definitions (``enum rte_flow_error_type``), removal
+ of the unused DUP action (``enum rte_flow_action_type``), modified
+ behavior for flow rule actions (see API changes), removal of C99 flexible
+ array from RAW pattern item (``struct rte_flow_item_raw``), complete
+ rework of the RSS action definition (``struct rte_flow_action_rss``),
+ sanity fix in the VLAN pattern item (``struct rte_flow_item_vlan``) and
+ new transfer attribute (``struct rte_flow_attr``).
+
+**New parameter added to rte_bbdev_op_cap_turbo_dec.**
+
+ A new parameter ``max_llr_modulus`` has been added to
+ ``rte_bbdev_op_cap_turbo_dec`` structure to specify maximal LLR (likelihood
+ ratio) absolute value.
+
+* **BBdev Queue Groups split into UL/DL Groups**
+
+ Queue Groups have been split into UL/DL Groups in Turbo Software Driver.
+ They are independent for Decode/Encode. ``rte_bbdev_driver_info`` reflects
+ introduced changes.
+
+
Removed Items
-------------
Also, make sure to start the actual text at the margin.
=========================================================
+* **pdump is not compatible with old applications.**
+
+ As we changed to use generic multi-process communication for pdump negotiation
+ instead of previous dedicated unix socket way, pdump applications, including
+ dpdk-pdump example and any other applications using librte_pdump, cannot work
+ with older version DPDK primary applications.
