Communications Broker (Comm Broker) now runs in a Docker container. This improves security, removing the requirement to maintain a specific version of Linux.
OS compatibility
Comm Broker 2.5.1 is compatible with most versions of Linux that support Docker.
Upgrade support
You cannot upgrade directly to version 2.5.1. Instead, you must download the Comm Broker 2.5.1 package, uninstall the previous version of Comm Broker, and perform a clean install as described in the Unmanaged Communications Broker Installation and Configuration Guide.
