Yup, the group serialization won't change, so the files should remain compatible. In fact the "real" useful change will be turning the servers into objects, but that will take a lot of work, and these other changes are sort of meant to "clear out the undergrowth" first, as it were. > Please write tests when doing this refactoring work, so that it is > easier to detect when changes cause compatibility problems. Will do -- another (eventual) goal of these changes is to separate out data structures from representation, so the tests could create a dummy server and groups and test them without needing a whole installation in place.
