kops: kubefed v1.7.2 Unable to join cluster to federation - error: server does not support API version "federation/v1beta1"

I am working on creating a federation with three clusters created with kops. The clusters spin up and I am able to init the federation successfully. However when I try to join one of the clusters I receive an error error: server does not support API version "federation/v1beta1"

Here are the steps I took:

#Create the "master"
kops create cluster --zones=us-west-1a federation-master.example.com
kops edit cluster federation-master.example.com
 -- Update Kubernetes version 1.7.0 to 1.7.2 
kops update cluster federation-master.example.com --yes

#Create the two "slaves"
kops create cluster --zones=us-east-2a ohio-slave.example.com
kops edit cluster ohio-slave.example.com
 -- Update Kubernetes version 1.7.0 to 1.7.2 
kops update cluster ohio-slave.example.com --yes

kops create cluster --zones=us-west-2a oregon-slave.example.com
kops edit cluster oregon-slave.example.com
 -- Update Kubernetes version 1.7.0 to 1.7.2 
kops update cluster oregon-slave.example.com --yes

#Initialize the federation
kubefed init testenv-federation --host-cluster-context=federation-master.example.com --dns-provider="aws-route53" --dns-zone-name="example.com."

This is not the first attempt at running federated kops clusters. I have successfully joined two “slave” clusters with kubefed v1.6.7 on top of clusters created with kops v.1.6.2. There are some features in 1.7 that I would like to leverage so I wanted to get a new federation created with kubefed/kubectl v1.7.2.
