Diffing man 5 postconf changes between releases


I currently use Postfix version 3.1.0. I know that there are announcements of feature changes between each release of Postfix via e-mail and I read these, but I was wondering if there was an easy way to see the changes to the configuration parameters between versions ?

For example, can I somehow diff the difference between man 5 postconf on version 3.1.0 and the current release of Postfix ? When I say diff, I am hoping to be able to see just the new configuration parameters.

The only way I can think of doing this is to dump the default configuration from postconf from one version and then diff that against the default configuration from postconf from the current version. That will tell me new parameters, but it won’t show me if the documentation for existing parameters has changed.

If there isn’t an easy way to do this, is this in fact documented somewhere (perhaps a list of configuration parameter changes on the website that I just haven’t found yet) ?
