That's the intended behavior of mixed-version clusters -- once an older
node leaves the cluster, it can't rejoin without being upgraded. This
allows new features to become available once all older nodes are gone.
Mixed-version clusters should only be used in a rolling upgrade, i.e.
upgrading each node in turn and returning it to the cluster.

The feature set applies to all RPMs of a particular version. You can't
mix and match RPMs from different versions.

The feature set of each released version can be seen at:
1.1.13 through 1.1.15 had feature set 3.0.10

The stock packages in the repos should be fine. All newer versions
support rolling upgrades from 1.1.13.
