[pgpool-general: 8208] Upgrading pgpool in a cluster

I'm currently running pgpool 4.1.4. I'd like to upgrade to the latest stable release, 4.3.2. I have a cluster with 3 pgpool nodes running in it. Is it possible to upgrade a single host in the cluster and have them still talk to each other? Or will I need to take down the cluster and upgrade all nodes at once?
