+* **Added bucket mempool driver.**
+
+  Added bucket mempool driver which provides a way to allocate contiguous
+  block of objects.
+  Number of objects in the block depends on how many objects fit in
+  RTE_DRIVER_MEMPOOL_BUCKET_SIZE_KB memory chunk which is build time option.
+  The number may be obtained using rte_mempool_ops_get_info() API.
+  Contiguous blocks may be allocated using rte_mempool_get_contig_blocks() API.

+* **Added IFCVF vDPA driver.**
+
+  Added IFCVF vDPA driver to support Intel FPGA 100G VF device. IFCVF works
+  as a HW vhost data path accelerator, it supports live migration and is
+  compatible with virtio 0.95 and 1.0. This driver registers ifcvf vDPA driver

+* **Added OcteonTx TIM Driver (Event timer adapter).**
+
+  The OcteonTx Timer block enables software to schedule events for a future
+  time, it is exposed to an application via Event timer adapter library.
+
+  See the :doc:`../eventdevs/octeontx` guide for more details
+
+* **Added DPAA2 QDMA Driver (in rawdev).**
+
+  The DPAA2 QDMA is an implementation of the rawdev API, that provide means
+  to initiate a DMA transaction from CPU. The initiated DMA is performed
+  without CPU being involved in the actual DMA transaction.
+
+  See the :doc:`../rawdevs/dpaa2_qdma` guide for more details.
+
+* **Added DPAA2 Command Interface Driver (in rawdev).**
+
+  The DPAA2 CMDIF is an implementation of the rawdev API, that provides
+  communication between the GPP and NXP's QorIQ based AIOP Block (Firmware).
+  Advanced IO Processor i.e. AIOP is clusters of programmable RISC engines
+  optimised for flexible networking and I/O operations. The communication
+  between GPP and AIOP is achieved via using DPCI devices exposed by MC for
+  GPP <--> AIOP interaction.

+* service cores: no longer marked as experimental.
+
+  The service cores functions are no longer marked as experimental, and have
+  become part of the normal DPDK API and ABI. Any future ABI changes will be
+  announced at least one release before the ABI change is made. There are no
+  ABI breaking changes planned.

+* ethdev: several changes were made to the flow API.
+
+  * Unused DUP action was removed.
+  * Actions semantics in flow rules: list order now matters ("first
+    to last" instead of "all simultaneously"), repeated actions are now
+    all performed, and they do not individually have (non-)terminating
+    properties anymore.
+  * Flow rules are now always terminating unless a PASSTHRU action is
+    present.
+  * C99-style flexible arrays were replaced with standard pointers in RSS
+    action and in RAW pattern item structures due to compatibility issues.
+  * The RSS action was modified to not rely on external
+    ``struct rte_eth_rss_conf`` anymore to instead expose its own and more
+    appropriately named configuration fields directly
+    (``rss_conf->rss_key`` => ``key``,
+    ``rss_conf->rss_key_len`` => ``key_len``,
+    ``rss_conf->rss_hf`` => ``types``,
+    ``num`` => ``queue_num``), and the addition of missing RSS parameters
+    (``func`` for RSS hash function to apply and ``level`` for the
+    encapsulation level).
+  * The VLAN pattern item (``struct rte_flow_item_vlan``) was modified to
+    include inner EtherType instead of outer TPID. Its default mask was also
+    modified to cover the VID part (lower 12 bits) of TCI only.
+  * A new transfer attribute was added to ``struct rte_flow_attr`` in order
+    to clarify the behavior of some pattern items.
+  * PF and VF pattern items are now only accepted by PMDs that implement
+    them (bnxt and i40e) when the transfer attribute is also present for
+    consistency.
+  * Pattern item PORT was renamed PHY_PORT to avoid confusion with DPDK port
+    IDs.
+  * An action counterpart to the PHY_PORT pattern item was added in order to
+    redirect matching traffic to a specific physical port.
+  * PORT_ID pattern item and actions were added to match and target DPDK
+    port IDs at a higher level than PHY_PORT.
+
+* ethdev: change flow APIs regarding count action:
+  * ``rte_flow_create()`` API count action now requires the ``struct rte_flow_action_count``.
+  * ``rte_flow_query()`` API parameter changed from action type to action structure.
