--- Comment #4 from Jeremy Eder jeder@redhat.com --- There was a user request in the github issue for an updated flannel in F22. He specifically was looking for 0.5.3, so I guess that should be alright. Although if you are going to push an update, maybe just push the latest 0.5.4. Your call.
Thanks!
