=========================================================
+* **Reorganized the mbuf structure.**
+
+ * Align fields to facilitate the writing of ``data_off``, ``refcnt``, and
+ ``nb_segs`` in one operation.
+ * Use 2 bytes for port and number of segments.
+ * Move the sequence number in the second cache line.
+ * Add a timestamp field.
+ * Set default value for ``refcnt``, ``next`` and ``nb_segs`` at mbuf free.
+
+* **Added mbuf raw free API**
+
+ Moved ``rte_mbuf_raw_free()`` and ``rte_pktmbuf_prefree_seg()`` functions to
+ the public API.
+
* **Added free Tx mbuf on demand API.**
Added a new function ``rte_eth_tx_done_cleanup()`` which allows an application
to request the driver to release mbufs from their Tx ring that are no longer
in use, independent of whether or not the ``tx_rs_thresh`` has been crossed.
+* **Added EAL dynamic log framework.**
+
+ Added new APIs to dynamically register named log types, and control
+ the level of each type independently.
+
* **Added descriptor status ethdev API.**
Added a new API to get the status of a descriptor.
* **Added interrupt mode support for virtio-user.**
- Implemented Rxq interrupt mode support for virtio-user as a virtual
+ Implemented Rxq interrupt mode and LSC support for virtio-user as a virtual
device. Supported cases:
* Rxq interrupt for virtio-user + vhost-user as the backend.
* Rxq interrupt for virtio-user + vhost-kernel as the backend.
+ * LSC interrupt for virtio-user + vhost-user as the backend.
+
+* **Added event driven programming model library (rte_eventdev).**
+
+ This API introduces event driven programming model.
+
+ In a polling model, lcores poll ethdev ports and associated
+ rx queues directly to look for packet. In an event driven model,
+ by contrast, lcores call the scheduler that selects packets for
+ them based on programmer-specified criteria. Eventdev library
+ added support for event driven programming model, which offer
+ applications automatic multicore scaling, dynamic load balancing,
+ pipelining, packet ingress order maintenance and
+ synchronization services to simplify application packet processing.
+
+ By introducing event driven programming model, DPDK can support
+ both polling and event driven programming models for packet processing,
+ and applications are free to choose whatever model
+ (or combination of the two) that best suits their needs.
+
+* **Added Software Eventdev PMD.**
+
+ Added support for the software eventdev PMD. The software eventdev is a
+ software based scheduler device that implements the eventdev API. This
+ PMD allows an application to configure a pipeline using the eventdev
+ library, and run the scheduling workload on a CPU core.
+
+* **Added Cavium OCTEONTX Eventdev PMD.**
+
+ Added the new octeontx ssovf eventdev driver for OCTEONTX devices. See the
+ "Event Device Drivers" document for more details on this new driver.
Resolved Issues

=========================================================
+* **LSC interrupt cannot work for virtio-user + vhost-kernel.**
+
+ LSC interrupt cannot be detected when setting the backend, tap device,
+ up/down as we fail to find a way to monitor such event.

API Changes
-----------
flagged by the compiler. The return value usage should be checked
while fixing the compiler error due to the extra parameter.
+* **Reworked rte_vhost library**
+
+ The rte_vhost library has been reworked to make it generic enough so that
+ user could build other vhost-user drivers on top of it. To achieve that,
+ following changes have been made:
+
+ * The following vhost-pmd APIs are removed:
+
+ * ``rte_eth_vhost_feature_disable``
+ * ``rte_eth_vhost_feature_enable``
+ * ``rte_eth_vhost_feature_get``
+
+ * The vhost API ``rte_vhost_driver_callback_register(ops)`` is reworked to
+ be per vhost-user socket file. Thus, it takes one more argument:
+ ``rte_vhost_driver_callback_register(path, ops)``.
+
+ * The vhost API ``rte_vhost_get_queue_num`` is deprecated, instead,
+ ``rte_vhost_get_vring_num`` should be used.
+
+ * Following macros are removed in ``rte_virtio_net.h``
+
+ * ``VIRTIO_RXQ``
+ * ``VIRTIO_TXQ``
+ * ``VIRTIO_QNUM``
+
+ * Following net specific header files are removed in ``rte_virtio_net.h``
+
+ * ``linux/virtio_net.h``
+ * ``sys/socket.h``
+ * ``linux/if.h``
+ * ``rte_ether.h``
+
+ * The vhost struct ``virtio_net_device_ops`` is renamed to
+ ``vhost_device_ops``
+
+ * The vhost API ``rte_vhost_driver_session_start`` is removed. Instead,
+ ``rte_vhost_driver_start`` should be used, and no need to create a
+ thread to call it.
+
+ * The vhost public header file ``rte_virtio_net.h`` is renamed to
+ ``rte_vhost.h``
+
+
