I agree that we shouldn't be polluting our code to support obsolete formats prior to the 1.0 release.

Another simple option is to start a Wiki page documenting all configuration format changes that may impact existing users (each change identified with a SVN version) and when we release a milestone add it to the wiki page to indicate where the milestones are in relation to the svn versions.  This way a user can look up the changes impacting their existing configurations since the version/milestone they were using.  Each change on the wiki could have a short description and a link to the JIRA issue that discusses it in detail (since the JIRA issues will be used for the release notes in milestone releases). The descriptions in the JIRA issues should explain the issue with the configuration format prior to the change, an overview of the new format and the changes the user must make to move to the new configuration format.

Hopefully there won't be heaps of these changes, but IMHO at this stage of the game it would be a pitty getting bogged down in backwards compatibility.  We should have a disclaimer about compatibility for milestone and unstable builds on the download page to ensure users have reasonable expectations.
