v21.12.0 was released on 22 December, 2021.
Release Notes:
OVN v21.12.0 - 22 Dec 2021
--------------------------
- Set ignore_lsp_down to true as default, so that ARP responder flows are
installed together with other flows when a logical switch port is created,
without having to wait for the port to be UP. CMS should set it to false
if not desired.
- Added Load_Balancer_Group support, which simplifies large scale
configurations of load balancers.
- Introduced infrastructure for VIF plug providers. When OVN is linked with
an appropriate VIF plug provider CMS can request OVN to plug lports. This
is particularly useful in topologies where the ovn-controller process is
running on SmartNIC control plane CPUs. Please refer to
Documentation/topics/vif-plug-providers/vif-plug-providers.rst for more
information.
- Added Logical_Router_Port "gateway_mtu_bypass" option.
- Added new "inc-engine/recompute" command to all incremental processing
engine clients (ovn-northd and ovn-controller).
- ovn-controller: Add configuration knob, through OVS external-id
"ovn-trim-timeout-ms" to allow specifiying an lflow cache inactivity
timeout after which ovn-controller should trim memory.
