=========================================================
+* **Added PMD-recommended Tx and Rx parameters**
+
+ Applications can now query drivers for device-tuned values of
+ ring sizes, burst sizes, and number of queues.
+
* **Added RSS hash and key update to CXGBE PMD.**
Support to update RSS hash and key has been added to CXGBE PMD.
* Added support for NVGRE, VXLAN and GENEVE filters in flow API.
* Added support for DROP action in flow API.
+* **Added Ethernet poll mode driver for AMD XGBE devices.**
+
+ Added the new ``axgbe`` 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.
+
+* **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 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 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 device event monitor framework.**
+
+ Added a general device event monitor framework at EAL, for device dynamic management.
+ Such as device hotplug awareness and actions adopted accordingly. The list of new APIs:
+
+ * ``rte_dev_event_monitor_start`` and ``rte_dev_event_monitor_stop`` are for
+ the event monitor enable and disable.
+ * ``rte_dev_event_callback_register`` and ``rte_dev_event_callback_unregister``
+ are for the user's callbacks register and unregister.
+
+ Linux uevent is supported as backend of this device event notification framework.

API Changes
-----------

=========================================================
+* mbuf: The control mbuf API has been removed in v18.05. The impacted
+ functions and macros are:
+
+ - ``rte_ctrlmbuf_init()``
+ - ``rte_ctrlmbuf_alloc()``
+ - ``rte_ctrlmbuf_free()``
+ - ``rte_ctrlmbuf_data()``
+ - ``rte_ctrlmbuf_len()``
+ - ``rte_is_ctrlmbuf()``
+ - ``CTRL_MBUF_FLAG``
+
+ The packet mbuf API should be used as a replacement.
+
+* meter: updated to accommodate configuration profiles.
+
+ The meter API is changed to support meter configuration profiles. The
+ configuration profile represents the set of configuration parameters
+ for a given meter object, such as the rates and sizes for the token
+ buckets. These configuration parameters were previously the part of meter
+ object internal data strcuture. The separation of the configuration
+ parameters from meter object data structure results in reducing its
+ memory footprint which helps in better cache utilization when large number
+ of meter objects are used.
+
+* ethdev, in struct ``struct rte_eth_dev_info``, field ``rte_pci_device *pci_dev``
+ replaced with field ``struct rte_device *device``.
+
+* **Changes to semantics of rte_eth_dev_configure() parameters.**
+
+ If both the ``nb_rx_q`` and ``nb_tx_q`` parameters are zero,
+ ``rte_eth_dev_configure`` will now use PMD-recommended queue sizes, or if
+ recommendations are not provided by the PMD the function will use ethdev
+ fall-back values. Previously setting both of the parameters to zero would
+ have resulted in ``-EINVAL`` being returned.
+
+* **Changes to semantics of rte_eth_rx_queue_setup() parameters.**
+
+ If the ``nb_rx_desc`` parameter is zero, ``rte_eth_rx_queue_setup`` will
+ now use the PMD-recommended Rx ring size, or in the case where the PMD
+ does not provide a recommendation, will use an ethdev-provided
+ fall-back value. Previously, setting ``nb_rx_desc`` to zero would have
+ resulted in an error.
+
+* **Changes to semantics of rte_eth_tx_queue_setup() parameters.**
+
+ If the ``nb_tx_desc`` parameter is zero, ``rte_eth_tx_queue_setup`` will
+ now use the PMD-recommended Tx ring size, or in the case where the PMD
+ does not provide a recoomendation, will use an ethdev-provided
+ fall-back value. Previously, setting ``nb_tx_desc`` to zero would have
+ resulted in an error.
+
ABI Changes

=========================================================
+* 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.
+
+* **Additional fields in rte_eth_dev_info.**
+
+ The ``rte_eth_dev_info`` structure has had two extra entries appended to the
+ end of it: ``default_rxportconf`` and ``default_txportconf``. Each of these
+ in turn are ``rte_eth_dev_portconf`` structures containing three fields of
+ type ``uint16_t``: ``burst_size``, ``ring_size``, and ``nb_queues``. These
+ are parameter values recommended for use by the PMD.
