We are glad to announce the release of:
neutron 21.1.0: OpenStack Networking
This release is part of the zed stable release series.
The source is available from:
https://opendev.org/openstack/neutron
Download the package from:

Please report issues through:
https://bugs.launchpad.net/neutron/+bugs
For more details, please see below.
21.1.0
^^^^^^
New Features
************
* Address scope is now added to all OVN LSP port registers in the
northbound. Northd then writes the address scope from the northbound
to the southbound so it can be used there by the ovn-bgp-agent.
Known Issues
************
* Until the OVN bug
(https://bugzilla.redhat.com/show_bug.cgi?id=2162756) is fixed,
setting the "reside-on-redirect-chassis" to true for the logical
router port associated to vlan provider network is needed. This
workaround makes the traffic centrallized, but not tunneled, through
the node with the gateway port, thus avoiding MTU issues.
Upgrade Notes
*************
* The default value for the "metadata_workers" configuration option
has changed to 0 for the ML2/OVN driver. Since [OVN] Allow to
execute "MetadataProxyHandler" in a local thread
(https://review.opendev.org/c/openstack/neutron/+/861649), the OVN
metadata proxy handler can be spawned in the same process of the OVN
metadata agent, in a local thread. That reduces the number of OVN SB
database connections to one.
Bug Fixes
*********
* [bug 2003455 (https://bugs.launchpad.net/neutron/+bug/2003455)] It
is added an extra checking to ensure the "reside-on-redirect-
chassis" is set to true for the logical router port associated to
vlan provider network despite having the
"ovn_distributed_floating_ip" enabled or not. This is needed as
there is an OVN bug
(https://bugzilla.redhat.com/show_bug.cgi?id=2162756) making it not
work as expected. Until that is fixed, we need these workaround that
makes the traffic centrallized, but not tunneled, through the node
with the gateway port, thus avoiding MTU issues.
* Normalise OVN agent heartbeat timestamp format to match other
agent types. This fixes parsing of "GET /v2.0/agents" for some
clients, such as gophercloud.
* Neutron can record full connection using log-related feature
introduced in OVN 21.12. For more info see *bug
LP#<https://bugs.launchpad.net/neutron/+bug/2003706>*
Other Notes
***********
* Since OVN 20.06, the "Chassis" register configuration is stored in
the "other_config" field and replicated into "external_ids". This
replication is stopped in OVN 22.09. The ML2/OVN plugin tries to
retrieve the "Chassis" configuration from the "other_config" field
first; if this field does not exist (in OVN versions before 20.06),
the plugin will use "external_ids" field instead. Neutron will be
compatible with the different OVN versions (with and without
"other_config" field).
