==================
.. **Read this first.**
The text in the sections below explains how to update the release notes.
Use proper spelling, capitalization and punctuation in all sections.
Variable and config names should be quoted as fixed width text:
``LIKE_THIS``.

New Features
------------
.. This section should contain new features added in this release.
Sample format:
* **Add a title in the past tense with a full stop.**
Add a short 1-2 sentence description in the past tense.
The description should be enough to allow someone scanning
the release notes to understand the new feature.
If the feature adds a lot of sub-features you can use a bullet list
like this:
* Added feature foo to do something.
* Enhanced feature bar to do something else.
Refer to the previous release notes for examples.
Suggested order in release notes items:
* Core libs (EAL, mempool, ring, mbuf, buses)
* Device abstraction libs and PMDs
- ethdev (lib, PMDs)
- cryptodev (lib, PMDs)
- eventdev (lib, PMDs)
- etc
* Other libs
* Apps, Examples, Tools (if significant)
This section is a comment. Do not overwrite or remove it.
Also, make sure to start the actual text at the margin.
=========================================================
* **Added non-EAL threads registration API.**
Added a new API to register non-EAL threads as lcores. This can be used by
applications to have its threads known to DPDK without suffering from the
non-EAL previous limitations in terms of performance.
* **rte_*mb APIs are updated to use the DMB instruction for ARMv8.**
ARMv8 memory model has been strengthened to require other-multi-copy
atomicity. This allows for using the DMB instruction instead of DSB for IO
barriers. The rte_*mb APIs, for ARMv8 platforms, have changed to use the DMB
instruction to reflect this.
* **Added support for RTS and HTS modes into mempool ring driver.**
Added the ability to select new ring synchronisation modes:
``relaxed tail sync (ring_mt_rts)`` and ``head/tail sync (ring_mt_hts)``
via the mempool ops API.
* **Added the support for vfio-pci new VF token interface.**
From Linux 5.7, vfio-pci supports to bind both SR-IOV PF and the created
VFs, where it uses a shared VF token (UUID) to represent the collaboration
between PF and VFs. The DPDK PCI driver has been updated to gain the access
to the PF and VFs devices by appending the VF token parameter.
* **Added the RegEx Library, a generic RegEx service library.**
Added the RegEx library which provides an API for offload of regular
expressions search operations to hardware or software accelerator devices.
Added Mellanox RegEx PMD, allowing to offload RegEx searches.
* **Added vhost async data path APIs.**
4 new APIs have been added to enable vhost async data path, including:
* Async device channel register/unregister APIs.
* Async packets enqueue/completion APIs (only split ring was implemented).
* **Added vDPA device APIs to query virtio queue statistics.**
Added new vDPA APIs to query virtio queue statistics, to get their names and
to reset them.
* **Updated Mellanox mlx5 vDPA driver.**
Updated Mellanox mlx5 vDPA driver with new features, including:
* Added support for virtio queue statistics.

The ``ECPRI`` item has been added to support eCPRI packet offloading for
5G network.

Added a new mbuf dynamic field and flag to provide a timestamp on which
packet transmitting can be synchronized. A device Tx offload flag has been
added to indicate the PMD supports send scheduling.
* **Updated PCAP driver.**
Updated PCAP driver with new features and improvements, including:
* Support software Tx nanosecond timestamps precision.
