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
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.**
+
+ Added the new ``ccp`` crypto driver for AMD CCP devices. See the
+ :doc:`../cryptodevs/ccp` crypto driver guide for more details on
+ this new driver.
+
+* **Updated AESNI MB PMD.**
+
+ The AESNI MB PMD has been updated with additional support for:
+
+ * AES-CMAC (128-bit key).
+
+* **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.
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.

API Changes
-----------
Also, make sure to start the actual text at the margin.
=========================================================
+* 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``.
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.
+
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.
