Do you have any external interfaces other than RESTCONF?
Yes, akka uses port 2550 and by default communicates with unencrypted, unauthenticated messages. Securing akka communication isn’t described here, but those concerned should look at the “Configuring SSL/TLS for Akka Remoting” section at http://doc.akka.io/docs/akka//2.4.17/scala/remoting.html.
Is this release compatible with the previous release?
Yes
Any API changes?
No
Any configuration changes?
Preview for Distributed Datastore Tell-Based protocol. This is enabled using etc/org.opendaylight.controller.cluster.datastore.cfg’s
use-tell-based-protocol knob and should eliminate most sources of AskTimeouts.
