Comment 31 for bug 1668093

Prior to the update I had a diff when rehashing like:
$ ssh-keyscan 10.245.71.133 > ~/.ssh/known_hosts; for i in $(seq 1 20); do ssh-keygen -H; diff -Naur ~/.ssh/known_hosts.old ~/.ssh/known_hosts; done

Removing the known_hosts file and upgrading to proposed version.

After the update I see one diff when initially adding the entries, but then now bad rehashing anymore.

Verified Xenial and Yakkety.
