+* **Added support for --base-virtaddr EAL option to FreeBSD.**
+
+ The FreeBSD version of DPDK now also supports setting base virtual address
+ for mapping pages and resources into its address space.
+
+* **Added Lock-free Stack for aarch64.**
+
+ Enabled the lock-free stack implementation for aarch64 platforms.
+
+* **Extended pktmbuf mempool private structure.**
+
+ rte_pktmbuf_pool_private structure was extended to include flags field
+ for future compatibility.
+ As per 19.11 release this field is reserved and should be set to 0
+ by the user.
+
++* **Changed mempool allocation behavior.**
+
+ Changed the mempool allocation behaviour so that objects no longer cross
+ pages by default. Note, this may consume more memory when using small memory
+ pages.
+
+* **Added support for dynamic fields and flags in mbuf.**
+
+ This new feature adds the ability to dynamically register some room
+ for a field or a flag in the mbuf structure. This is typically used
+ for specific offload features, where adding a static field or flag
+ in the mbuf is not justified.
+
+* **Added support for hairpin queues.**
+
+ On supported NICs, we can now setup hairpin queues which will offload packets
+ from the wire, back to the wire.
+
+* **Added flow tag in rte_flow.**
+
+ The ``SET_TAG`` action and ``TAG`` item have been added to support transient
+ flow tag.
+
+* **Extended metadata support in rte_flow.**
+
+ Flow metadata has been extended to both Rx and Tx.
+
+ * Tx metadata can also be set by SET_META action of rte_flow.
+ * Rx metadata is delivered to the host via a dynamic field of ``rte_mbuf``
+ with ``PKT_RX_DYNF_METADATA``.
+
+* **Added ethdev API to set supported packet types.**
+
+ * Added new API ``rte_eth_dev_set_ptypes`` which allows an application to
+ inform a PMD about a reduced range of packet types to handle.
+ * This scheme will allow PMDs to avoid lookup of internal ptype table on Rx
+ and thereby improve Rx performance if the application wishes to do so.
+
+* **Added Rx offload flag to enable or disable RSS update.**
+
+ * Added new Rx offload flag ``DEV_RX_OFFLOAD_RSS_HASH`` which can be used to
+ enable/disable PMDs write to ``rte_mbuf::hash::rss``.
+ * PMDs notify the validity of ``rte_mbuf::hash:rss`` to the application
+ by enabling ``PKT_RX_RSS_HASH`` flag in ``rte_mbuf::ol_flags``.
+
+* **Added Rx/Tx packet burst mode "get" API.**
+
+ Added two new functions ``rte_eth_rx_burst_mode_get`` and
+ ``rte_eth_tx_burst_mode_get`` that allow an application
+ to retrieve the mode information about Rx/Tx packet burst
+ such as Scalar or Vector, and Vector technology like AVX2.
+
+* **Added Hisilicon hns3 PMD.**
+
+ Added the new ``hns3`` net driver for the inbuilt Hisilicon Network
+ Subsystem 3 (HNS3) network engine found in the Hisilicon Kunpeng 920 SoC.
+ See the :doc:`../nics/hns3` guide for more details on this new driver.

+ user plane. Test and test-crypto-perf applications have been updated for
+ unit testing.
+

+
+* **Enabled Single Pass GCM acceleration on QAT GEN3.**
+
+ Added support for Single Pass GCM, available on QAT GEN3 only (Intel
+ QuickAssist Technology P5xxx). It is automatically chosen instead of the
+ classic 2-pass mode when running on QAT GEN3, significantly improving
+ the performance of AES GCM operations.
+

+
+ * Added support for asymmetric session-less operations.
+ * Added support for RSA algorithm with pair ``(n, d)`` private key
+ representation.

+
+* **Added external buffers support for dpdk-test-compress-perf tool.**
+

+ allocate and use memory zones as external buffers instead of keeping the
+ data directly in mbuf areas.
+
+* **Updated the IPSec library.**
+
+ * Added Security Associations (SA) Database API to ``librte_ipsec``. A new
+ test-sad application has also been introduced to evaluate and perform
+ custom functional and performance tests for an IPsec SAD implementation.
+
+ * Support fragmented packets in inline crypto processing mode with fallback
+ ``lookaside-none`` session. Corresponding changes are also added in the
+ IPsec Security Gateway application.
+
+* **Introduced FIFO for NTB PMD.**
+
+ Introduced FIFO for NTB (Non-transparent Bridge) PMD to support
+ packet based processing.
+
+* **Added eBPF JIT support for arm64.**
+
+ Added eBPF JIT support for arm64 architecture to improve the eBPF program
+ performance.
+
+* **Added RIB and FIB (Routing/Forwarding Information Base) libraries.**
+
+ Added Routing and Forwarding Information Base (RIB/FIB) libraries. RIB and
+ FIB can replace the LPM (Longest Prefix Match) library with better control
+ plane (RIB) performance. The data plane (FIB) can be extended with new
+ algorithms.
+
+* **Updated testpmd with a command for ptypes.**
+
+ * Added a console command to testpmd app, ``show port (port_id) ptypes`` which
+ gives ability to print port supported ptypes in different protocol layers.
+ * Packet type detection disabled by default for the supported PMDs.
+
+* **Added new l2fwd-event sample application.**
+
+ Added an example application ``l2fwd-event`` that adds event device support to
+ the traditional l2fwd example. It demonstrates usage of poll and event mode IO
+ mechanism under a single application.
+
+* **Added build support for Link Time Optimization.**
+
+ LTO is an optimization technique used by the compiler to perform whole
+ program analysis and optimization at link time. In order to do that
+ compilers store their internal representation of the source code that
+ the linker uses at the final stage of the compilation process.
+
+ See :doc:`../prog_guide/lto` for more information:
+
+* **Added IOVA as VA support for KNI.**
+
+ * Added IOVA = VA support for KNI. KNI can operate in IOVA = VA mode when
+ ``iova-mode=va`` EAL option is passed to the application or when bus IOVA
+ scheme is selected as RTE_IOVA_VA. This mode only works on Linux Kernel
+ versions 4.10.0 and above.
+
+ * Due to IOVA to KVA address translations, based on the KNI use case there
+ can be a performance impact. For mitigation, forcing IOVA to PA via EAL
+ ``--iova-mode=pa`` option can be used, IOVA_DC bus iommu scheme can also
+ result in IOVA as PA.
