+* **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.
