Known Changes and Deprecations

OVS agent deprecated in favor of OVN

Impact: Open vSwitch ML2 agent (openvswitch) is formally deprecated in 2025.2. It remains functional but will be removed in a future release. New deployments should use OVN.

Action: No immediate action required for existing OVS deployments. Plan migration to OVN for a future upgrade cycle. See deploy/reference/decision-guides/networking.md for migration guidance.


Podman support promoted to supported (from experimental)

Impact: Podman is now a fully supported container runtime alongside Docker in 2025.2. Previous versions treated Podman support as experimental.

Action: If using Podman, no changes needed. If considering switching from Docker to Podman, this can be done during an upgrade to 2025.2.

In globals.yml:

container_engine: "podman"  # default is "docker"
