The lock-free stack implementation is enabled for aarch64 platforms.
+* **Added support of 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.
+
* **Updated the enic driver.**
* Added support for Geneve with options offload.
Added the new PFE driver for the NXP LS1012A platform. See the
:doc:`../nics/pfe` NIC driver guide for more details on this new driver.
+* **Updated iavf PMD.**
+
+ Enable AVX2 data path for iavf PMD.
+
* **Updated the Intel e1000 driver.**
Added support for the ``RTE_ETH_DEV_CLOSE_REMOVE`` flag.
Added support for the ``RTE_ETH_DEV_CLOSE_REMOVE`` flag.
+* **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.
+ Another new function ``rte_eth_burst_mode_option_name`` is
+ provided for burst mode options stringification.
+
* **Updated the Intel ice driver.**

* Added support for device-specific DDP package loading.
* Added support for handling Receive Flex Descriptor.
* Added support for protocol extraction on per Rx queue.
+ * Added support for Flow Director filter based on generic filter framework.
* Added support for the ``RTE_ETH_DEV_CLOSE_REMOVE`` flag.
+ * Generic filter enhancement
+ - Supported pipeline mode.
+ - Supported new packet type like PPPoE for switch filter.
+ * Supported input set change and symmetric hash by rte_flow RSS action.
+ * Added support for GTP Tx checksum offload.
* **Added cryptodev asymmetric session-less operation.**
* Supported VLAN filter and VLAN offload.
* Supported Unicast MAC filter and Multicast MAC filter.
* Supported Flow director for LACP, VRRP, BGP and so on.
+ * Supported FW version get.
+
+* **Updated Mellanox mlx5 driver.**
+
+ Updated Mellanox mlx5 driver with new features and improvements, including:
+
+ * Added support for VLAN pop flow offload command.
+ * Added support for VLAN push flow offload command.
+ * Added support for VLAN set PCP offload command.
+ * Added support for VLAN set VID offload command.
+ * Added support for matching on packets withe Geneve tunnel header.
+
+* **Updated the AF_XDP PMD.**
+
+ Updated the AF_XDP PMD. The new features include:
+
+ * Enabled zero copy between application mempools and UMEM by enabling the
+ XDP_UMEM_UNALIGNED_CHUNKS UMEM flag.
* **Added Marvell NITROX symmetric crypto PMD.**
ipv4_cksum|udp_cksum|tcp_cksum|timestamp|
vlan_strip|vlan_filter|vlan_extend on|off
+* Removed AF_XDP pmd_zero copy vdev argument. Support is now auto-detected.
+
+* The following sample applications have been removed in this release:
+
+ * Exception Path
+ * L3 Forwarding in a Virtualization Environment
+ * Load Balancer
+ * Netmap Compatibility
+ * Quota and Watermark
+ * vhost-scsi

=========================================================
+* eal: made the ``lcore_config`` struct and global symbol private.
+
+* eal: removed the ``rte_cpu_check_supported`` function, replaced by
+ ``rte_cpu_is_supported`` since dpdk v17.08.
+
+* eal: removed the ``rte_malloc_virt2phy`` function, replaced by
+ ``rte_malloc_virt2iova`` since v17.11.
+
+* eal: made the ``rte_config`` struct and ``rte_eal_get_configuration``
+ function private.
+
+* mem: hid the internal ``malloc_heap`` structure and the
+ ``rte_malloc_heap.h`` header.
+
+* pci: removed the following functions deprecated since dpdk v17.11:
+
+ - ``eal_parse_pci_BDF`` replaced by ``rte_pci_addr_parse``
+ - ``eal_parse_pci_DomBDF`` replaced by ``rte_pci_addr_parse``
+ - ``rte_eal_compare_pci_addr`` replaced by ``rte_pci_addr_cmp``
+
+* The network structure ``esp_tail`` has been prefixed by ``rte_``.
+
+* The network definitions of PPPoE ethertypes have been prefixed by ``RTE_``.
+
+* The network structure for MPLS has been prefixed by ``rte_``.
+
* ethdev: changed ``rte_eth_dev_infos_get`` return value from ``void`` to
``int`` to provide a way to report various error conditions.
has been introduced in this release is used when used when all the packets
enqueued in the tx adapter are destined for the same Ethernet port & Tx queue.
+* sched: The pipe nodes configuration parameters such as number of pipes,
+ pipe queue sizes, pipe profiles, etc., are moved from port level structure
+ to subport level. This allows different subports of the same port to
+ have different configuration for the pipe nodes.
