The difference is that stable release features not change except in case of emergency, so you can upgrade from one stable Postfix version to the next without having to reconfigure Postfix. And when features do have to change, there is a great deal of backwards compatibility. The snapshot releases introduce new features, and those can still change in incompatible ways. For example, postscreen is a prototype that I threw together in a few weeks so that I could present some new measurements at a conference. Once this program is finished sites will almost certainly need to update configuration files. Wietse
