mod_pubsub_serverinfo: Include hostname in default pubsub node name This change ensures that every host publishes to a unique node by default, which is important when publishing info about multiple hosts. The old default node name was "serverinfo" The new default node name is in the format "serverinfo/example.com" where example.com is automatically replaced by the publishing host's name. This affects existing deployments in the following ways: - If you already configured pubsub_serverinfo_node explicitly in your config, then nothing will change, your current configuration will still be used. - If you did not specify it in your config (i.e. used the default) then the module will switch to publishing to the new node. If your configuration is correct this shouldn't be noticed, because the new node will automatically be created and configured by the module. If you want, you can clean up the old 'serverinfo' node using: prosodyctl shell pubsub delete_node pubsub.example.com serverinfo
