v23.03.1 was released on 29 August, 2023.
Release Notes:
OVN v23.03.1 - 29 Aug 2023
--------------------------
- Bug fixes
- CT entries are not flushed by default anymore whenever a load balancer
backend is removed. A new, per-LB, option 'ct_flush' can be used to
restore the previous behavior. Disabled by default.
- Always allow IPv6 Router Discovery, Neighbor Discovery, and Multicast
Listener Discovery protocols, regardless of ACLs defined.
- Send ICMP Fragmentation Needed packets back to offending ports when
communicating with multichassis ports using frames that don't fit through a
tunnel. This is done only for logical switches that are attached to a
physical network via a localnet port, in which case multichassis ports may
have an effective MTU different from regular ports and hence may need this
mechanism to maintain connectivity with other peers in the network.
- ECMP routes use L4_SYM dp-hash by default if the datapath supports it.
Existing sessions might get re-hashed to a different ECMP path when
OVN detects the algorithm support in the datapath during an upgrade
or restart of ovn-controller.
- Add CoPP for the svc_monitor_mac. This addresses CVE-2023-3153.
v23.03.0 was released on 3 March, 2023.
Release Notes:

systemd units.
