Comment 9 for bug 355086

Providing notification of this external to NEWS.Debian would mean adding it to the Release Notes. Typically, the Release Notes for each flavour of Ubuntu is restricted to packages shipped by default in that flavour. As wesnoth is not included by default in any flavour, this package is typically not considered for release notes. Significant changes for most packages are also reported in NEWS.Debian: if you are performing a distribution upgrade, and need to ensure data compatibility with new upstream versions of software, you may do best to inspect at least the NEWS.Debian changes for those packages of particular concern, if not the full changelog.

    Of course, if you want to write a data file conversion tool, I'm sure that would be appreciated upstream. In the presence of such a tool, it becomes feasible to attempt to migrate user data.
