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
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
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
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
-----------
* 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
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
- 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.
