for specific offload features, where adding a static field or flag
in the mbuf is not justified.
+* **Added hairpin queue.**
+
+ On supported NICs, we can now setup haipin queue which will offload packets
+ from the wire, backto the wire.
+
+* **Added flow tag in rte_flow.**
+
+ SET_TAG action and TAG item have been added to support transient flow tag.
+
+* **Extended metadata support in rte_flow.**
+
+ Flow metadata is extended to both Rx and Tx.
+
+ * Tx metadata can also be set by SET_META action of rte_flow.
+ * Rx metadata is delivered to host via a dynamic field of ``rte_mbuf`` with
+ PKT_RX_DYNF_METADATA.
+
* **Updated the enic driver.**
* Added support for Geneve with options offload.
``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.**
- 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 new device IDs to support E810_XXV devices.
* **Added cryptodev asymmetric session-less operation.**
* Enabled SR-IOV - Partially supported at this point, VFIO only.
* 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 Flow API for LACP, VRRP, BGP and so on.
* Supported FW version get.
* **Updated Mellanox mlx5 driver.**
* 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.
+ * Added hairpin support.
+ * Added ConnectX6-DX support.
* **Updated the AF_XDP PMD.**
* **Updated the IPSec library.**
- Added SA Database API to ``librte_ipsec``. A new test-sad application is also
- introduced to evaluate and perform custom functional and performance tests
- for IPsec SAD implementation.
+ * Added SA Database API to ``librte_ipsec``. A new test-sad application is also
+ introduced to evaluate and perform custom functional and performance tests
+ for IPsec SAD implementation.
+
+ * Support fragmented packets in inline crypto processing mode with fallback
+ ``lookaside-none`` session. Corresponding changes are also added in IPsec
+ Security Gateway application.
* **Introduced FIFO for NTB PMD.**
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 compilation process.

Removed Items
-------------
* ethdev: changed ``rte_eth_dev_owner_delete`` return value from ``void`` to
``int`` to provide a way to report various error conditions.
+* ethdev: The deprecated function ``rte_eth_dev_count`` was removed.
+ The function ``rte_eth_dev_count_avail`` is a drop-in replacement.
+ If the intent is to iterate over ports, ``RTE_ETH_FOREACH_*`` macros
+ are better port iterators.
+
+* ethdev: RTE_FLOW_ITEM_TYPE_META data endianness altered to host one.
+ Due to the new dynamic metadata field in mbuf is host-endian either, there
+ is the minor compatibility issue for applications in case of 32-bit values
+ supported.
+
+* ethdev: the tx_metadata mbuf field is moved to dymanic one.
+ PKT_TX_METADATA flag is replaced with PKT_TX_DYNF_METADATA.
+ DEV_TX_OFFLOAD_MATCH_METADATA offload flag is removed, now metadata
+ support in PMD is engaged on dynamic field registration.
+
* event: The function ``rte_event_eth_tx_adapter_enqueue`` takes an additional
input as ``flags``. Flag ``RTE_EVENT_ETH_TX_ADAPTER_ENQUEUE_SAME_DEST`` which
has been introduced in this release is used when used when all the packets
align the Ethernet header on receive and all known encapsulations
preserve the alignment of the header.
+* security: The field ``replay_win_sz`` has been moved from ipsec library
+ based ``rte_ipsec_sa_prm`` structure to security library based structure
+ ``rte_security_ipsec_xform``, which specify the Anti replay window size
+ to enable sequence replay attack handling.
+
+* ipsec: The field ``replay_win_sz`` has been removed from the structure
+ ``rte_ipsec_sa_prm`` as it has been added to the security library.
