Release notes for VPP 21.01
===========================

Release Highlights
------------------

The FD.io VPP 20.09 release comprises more than 562 commits since the
previous release, including 274 fixes. Notable changes in this release
were the Virtio driver adding packet buffering on the transmit path to
handle slow back-ends which often have jitter and delays in free’ing
buffers, and also adding support for Virtio 1.1 packed rings. FD.io VPP
IPSEC added support for multi-point on IPSec interfaces, brings the
meshed benefits of IP to IPSec tunnels. The FD.io VPP Cloud NAT (CNAT),
added support source NAT ICMP and DHCP. The FD.io VPP FIB added support
for source address selection (SAS) and flow hashing on the inner
packets. Finally the FD.io VPP Perfmon plugin has been substantially
rewritten, to support measuring bundles of counters, and reporting
statistics per graph node.

Reflecting the API change policy introduced in the 20.09, please review
the following sections below: - Newly deprecated API messages: please
note that if you are using a deprecated message, they will soon be
removed in a subsequent release. Collaborate with the feature maintainer
on the best approach to mitigate. - In-progress API messages: They are
work-in-progress, and are *not* subject to the policy, and may change or
even be removed at any time. Please collaborate with the feature
maintainer on plans to productize the message before using in any
product. In-progress APIs must eventually become stable or be removed.
