Upgrade notes

Read the upgrade notes carefully before upgrading Tetragon. Depending on your setup, changes listed here might require a manual intervention.

TracingPolicy (k8s CRD)

returnArgAction no longer accepts Post. Use returnArg to include the return value in events, and omit returnArgAction for the default return-value behavior. Only TrackSock and UntrackSock are supported. Existing policies that set returnArgAction: "Post" should remove the field.
