Hi Folks, What do people think about adding a version number to the notification systems, so that consumers of notification messages are protected to some extent from changes in the message contents ? For example, would it be enough to add a version number to the messages - or should we have the version number as part of the topic itself (so that the notification system can provide both a 1.0 and 1.1 feed), etc ?
