ceph-deploy with --release (--stable) for dumpling?

[nigel.d.williams@xxxxxxxxx (Nigel Williams)]

ceph-deploy --release dumpling or previously ceph-deploy --stable
dumpling now results in Firefly (0.80.1) being installed, is this
intentional?

I'm adding another host with more OSDs and guessing it is preferable
to deploy the same version.
