=========================================================
+* **Added support to free hugepages exactly as originally allocated.**
+
+ Some applications using memory event callbacks (especially for managing
+ RDMA memory regions) require that memory be freed back to the system
+ exactly as it was originally allocated. These applications typically
+ also require that a malloc allocation not span across two separate
+ hugepage allocations. A new ``--match-allocations`` EAL init flag has
+ been added to fulfill both of these requirements.
+
+* **Added API to register external memory in DPDK.**
+
+ A new ``rte_extmem_register``/``rte_extmem_unregister`` API was added to allow
+ chunks of external memory to be registered with DPDK without adding them to
+ the malloc heap.
+
+* **Support for using virtio-user without hugepages**
+
+ The --no-huge mode was augmented to use memfd-backed memory (on systems that
+ support memfd), to allow using virtio-user-based NICs without hugepages.
+
* **Updated the enic driver.**
* Added support for ``RTE_ETH_DEV_CLOSE_REMOVE`` flag.
* Added the handler to get firmware version string.
* Added support for multicast filtering.
+* **Added dynamic queues allocation support for i40e VF.**
+
+ Previously, available queues of VF is reserved by PF at initialize stage.
+ Now both DPDK PF and Kernel PF (>=2.1.14) will support dynamic queue
+ allocation. At runtime, when VF request more queue number exceed the initial
+ reserved amount, PF can allocate up to 16 queues as the request after a VF
+ reset.
+
+* **Added ICE net PMD**
+
+ Added the new ``ice`` net driver for IntelĀ® Ethernet Network Adapters E810.
+ See the :doc:`../nics/ice` NIC guide for more details on this new driver.
+
+* **Added support for SW-assisted VDPA live migration.**
+
+ This SW-assisted VDPA live migration facility helps VDPA devices without
+ logging capability to perform live migration, a mediated SW relay can help
+ devices to track dirty pages caused by DMA. IFC driver has enabled this
+ SW-assisted live migration mode.
+
+* **Added security checks to cryptodev symmetric session operations.**
+
+ Added a set of security checks to the access cryptodev symmetric session.
+ The checks include the session's user data read/write check and the
+ session private data referencing status check while freeing a session.
+
+* **Updated the AESNI-MB PMD.**
+
+ * Add support for intel-ipsec-mb version 0.52.
+ * Add AES-GMAC algorithm support.
+ * Add Plain SHA1, SHA224, SHA256, SHA384, and SHA512 algorithms support.
+
+* **Enabled checksum support in the ISA-L compressdev driver.**
+
+ Added support for both adler and crc32 checksums in the ISA-L PMD.
+ This aids data integrity across both compression and decompression.
+
+* **Added a compression performance test tool.**
+
+ Added a new performance test tool to test the compressdev PMD. The tool tests
+ compression ratio and compression throughput.

Removed Items

Also, make sure to start the actual text at the margin.
=========================================================
+* eal: Function ``rte_bsf64`` in ``rte_bitmap.h`` has been renamed to
+ ``rte_bsf64_safe`` and moved to ``rte_common.h``. A new ``rte_bsf64`` function
+ has been added in ``rte_common.h`` that follows convention set by existing
+ ``rte_bsf32`` function.
+
+* eal: Segment fd API on Linux now sets error code to ``ENOTSUP`` in more cases
+ where segment fd API is not expected to be supported:
+
+ - On attempt to get segment fd for an externally allocated memory segment
+ - In cases where memfd support would have been required to provide segment
+ fd's (such as in-memory or no-huge mode)
+
+* eal: Functions ``rte_malloc_dump_stats()``, ``rte_malloc_dump_heaps()`` and
+ ``rte_malloc_get_socket_stats()`` are no longer safe to call concurrently with
+ ``rte_malloc_heap_create()`` or ``rte_malloc_heap_destroy()`` function calls.
+
+* sched: As result of the new format of the mbuf sched field, the
+ functions ``rte_sched_port_pkt_write()`` and
+ ``rte_sched_port_pkt_read_tree_path()`` got an additional parameter of
+ type ``struct rte_sched_port``.
+
* pdump: The ``rte_pdump_set_socket_dir()``, the parameter ``path`` of
``rte_pdump_init()`` and enum ``rte_pdump_socktype`` were deprecated
since 18.05 and are removed in this release.
+* cryptodev: The parameter ``session_pool`` in the function
+ ``rte_cryptodev_queue_pair_setup()`` is removed.
+
+* cryptodev: a new function ``rte_cryptodev_sym_session_pool_create()`` is
+ introduced. This function is now mandatory when creating symmetric session
+ header mempool. Please note all crypto applications are required to use this
+ function from now on. Failed to do so will cause
+ ``rte_cryptodev_sym_session_create()`` function call return error.
+
ABI Changes
-----------
Also, make sure to start the actual text at the margin.
=========================================================
+* mbuf: The format of the sched field of ``rte_mbuf`` has been changed
+ to include the following fields: ``queue ID``, ``traffic class``, ``color``.
+
+* cryptodev: as shown in the the 18.11 deprecation notice, the structure
+ ``rte_cryptodev_qp_conf`` has been added two parameters of symmetric session
+ mempool and symmetric session private data mempool.
+
+* cryptodev: as shown in the the 18.11 deprecation notice, the structure
+ ``rte_cryptodev_sym_session`` has been updated to contain more information
+ to ensure safely accessing the session and session private data.
+
+* security: New field ``uint64_t opaque_data`` is added into
+ ``rte_security_session`` structure. That would allow upper layer to easily
+ associate/de-associate some user defined data with the security session.
