* **Add new vDPA PMD based on Mellanox devices.**
Added a new Mellanox vDPA (``mlx5_vdpa``) PMD.
See the :doc:`../vdpadevs/mlx5` guide for more details on this driver.
* **Added support for virtio-PMD notification data.**
Added support for virtio-PMD notification data so that the driver
passes extra data (besides identifying the virtqueue) in its device
notifications, expanding the notifications to include the avail index and
avail wrap counter (When split ring is used, the avail wrap counter is not
included in the notification data).
* **Updated testpmd application.**
Added support for ESP and L2TPv3 over IP rte_flow patterns to the testpmd
application.
* **Added algorithms to cryptodev API.**
Added new algorithms to the cryptodev API:
* ECDSA (Elliptic Curve Digital Signature Algorithm) is added to
asymmetric crypto library specifications.
* ECPM (Elliptic Curve Point Multiplication) is added to
asymmetric crypto library specifications.
* **Added synchronous Crypto burst API.**
A new API has been introduced in the crypto library to handle synchronous cryptographic
operations allowing it to achieve performance gains for cryptodevs which use
CPU based acceleration, such as Intel AES-NI. An implementation for aesni_gcm
cryptodev is provided. The IPsec example application and ipsec library itself
were changed to allow utilization of this new feature.
* **Added handling of mixed algorithms in encrypted digest requests in QAT PMD.**
Added handling of mixed algorithms in encrypted digest hash-cipher
(generation) and cipher-hash (verification) requests (e.g. SNOW3G + ZUC or
ZUC + AES CTR) in QAT PMD possible when running on GEN3 QAT hardware.
Such algorithm combinations are not supported on GEN1/GEN2 hardware
and executing the request returns ``RTE_CRYPTO_OP_STATUS_INVALID_SESSION``.
* **Queue-pairs are now thread-safe on Intel QuickAssist Technology (QAT) PMD.**
Queue-pairs are thread-safe on Intel CPUs but Queues are not (that is, within
a single queue-pair all enqueues to the TX queue must be done from one thread
and all dequeues from the RX queue must be done from one thread, but enqueues
and dequeues may be done in different threads.).
* **Updated the ZUC PMD.**
* Transitioned underlying library from libSSO ZUC to intel-ipsec-mb
library (minimum version required 0.53).
* Removed dynamic library limitation, so PMD can be built as a shared
object now.
* **Updated the KASUMI PMD.**
* Transitioned underlying library from libSSO KASUMI to intel-ipsec-mb
library (minimum version required 0.53).
* **Updated the SNOW3G PMD.**
* Transitioned underlying library from libSSO SNOW3G to intel-ipsec-mb
library (minimum version required 0.53).
* **Changed armv8 crypto PMD external dependency.**
Changed armv8 crypto PMD external dependency. The
armv8 crypto PMD now depends on the Arm crypto library, and Marvell's
armv8 crypto library is not used anymore. The library name has been changed
from armv8_crypto to AArch64crypto.
* **Added inline IPsec support to Marvell OCTEON TX2 PMD.**
Added inline IPsec support to Marvell OCTEON TX2 PMD. With this feature,
applications will be able to offload entire IPsec offload to the hardware.
For the configured sessions, hardware will do the lookup and perform
decryption and IPsec transformation. For the outbound path, applications
can submit a plain packet to the PMD, and it will be sent out on the wire
after doing encryption and IPsec transformation of the packet.
* **Added Marvell OCTEON TX2 End Point rawdev PMD.**
Added a new OCTEON TX2 rawdev PMD for End Point mode of operation.
See the :doc:`../rawdevs/octeontx2_ep` for more details on this new PMD.
* **Added event mode to l3fwd sample application.**
Added event device support for the ``l3fwd`` sample application. It demonstrates
usage of poll and event mode IO mechanism under a single application.
* **Added cycle-count mode to the compression performance tool.**
Enhanced the compression performance tool by adding a cycle-count mode
which can be used to help measure and tune hardware and software PMDs.
* **Added OpenWrt howto guide.**
Added document which describes how to enable DPDK on OpenWrt in both virtual and
physical machines.
Removed Items
-------------
.. This section should contain removed items in this release. Sample format:
* Add a short 1-2 sentence description of the removed item
in the past tense.
This section is a comment. Do not overwrite or remove it.
Also, make sure to start the actual text at the margin.
=========================================================
* **Disabled building all the Linux kernel modules by default.**
In order to remove the build time dependency on the Linux kernel,
the Technical Board decided to disable all the kernel modules
by default from 20.02 version.
* **Removed coalescing feature from Intel QuickAssist Technology (QAT) PMD.**
The internal tail write coalescing feature was removed as not compatible with
dual-thread feature. It was replaced with a threshold feature. At busy times
if only a small number of packets can be enqueued, each enqueue causes
an expensive MMIO write. These MMIO write occurrences can be optimized by using
the new threshold parameter on process start. Please see QAT documentation for
more details.
API Changes
-----------
.. This section should contain API changes. Sample format:
* sample: Add a short 1-2 sentence description of the API change
which was announced in the previous releases and made in this release.
Start with a scope label like "ethdev:".
Use fixed width quotes for ``function_names`` or ``struct_names``.
Use the past tense.
This section is a comment. Do not overwrite or remove it.
Also, make sure to start the actual text at the margin.
=========================================================
* No change in this release.

ABI Changes
-----------
.. This section should contain ABI changes. Sample format:
* sample: Add a short 1-2 sentence description of the ABI change
which was announced in the previous releases and made in this release.
Start with a scope label like "ethdev:".
Use fixed width quotes for ``function_names`` or ``struct_names``.
Use the past tense.
This section is a comment. Do not overwrite or remove it.
Also, make sure to start the actual text at the margin.
=========================================================
* No change, kept ABI v20. DPDK 20.02 is compatible with DPDK 19.11.
* The soname for each stable ABI version should be just the ABI version major
number without the minor number. Unfortunately both major and minor were used
in the v19.11 release, causing version v20.x releases to be incompatible with
ABI v20.0.
The `commit f26c2b39b271 <https://git.dpdk.org/dpdk/commit/?id=f26c2b39b271>`_
fixed the issue by switching from 2-part to 3-part ABI version numbers so that
we can keep v20.0 as soname and using the final digits to identify the DPDK
20.x releases which are ABI compatible.
Tested Platforms
----------------
.. This section should contain a list of platforms that were tested
with this release.
The format is:
* <vendor> platform with <vendor> <type of devices> combinations
* List of CPU
* List of OS
* List of devices
* Other relevant details...
