Major changes include: - Much more readable reverse dependencies separated in groups - Improved recursive dependency report - More readable .config files: add comments to signal end of menus - More warnings for incorrect Config.in entries, such as a 'choice' default not contained in the 'choice' - Hability to properly display pseudographics with non-latin locales - Recursive dependencies are now treated as errors - this should make it harder for them to creep in.
