ssh - Unknown cipher type 'blowfish'

I just upgraded my Instance from Amazon Linux from "2016.03" to "2018.03" and now none of my autossh tunnels are working.

Turns out "blowfish" is no longer an accepable cypher for ssh.  Now it's "blowfish-cbc"

        [root@ip-10-0-0-89 init.d]# ssh -c blowfish 0
       Unknown cipher type 'blowfish'

         [root@ip-10-0-0-89 init.d]# ssh -V      
        OpenSSH_7.4p1, OpenSSL 1.0.2k-fips  26 Jan 2017

They renamed the cypher to "blowfish-cbc".

         [root@ip-10-0-0-89 init.d]# ssh -c blowfish-cbc 0
...works.
