As far as substantive releases go (adding new features as opposed to bug fixes), clearly some take longer than others. It seems to be the case that there are shorter release cycles in which you make one or two substantive additions to the game, and others that involve some major structural change which necessitates rewriting numerous aspects of the code and, therefore, results in a longer development time to the release.
How many major structural changes remain with DF that will require extended development cycles/release periods like the one that we are currently experiencing? Can you list the remaining major structural changes to DF that you presently envision as necessary to complete DF 1.0?
Obviously, development plans change and some releases take longer than others, so I don't mean for this question to pin you down on any specific development plan or release schedule, but I think it would be encouraging to me and the community to hear that there is some discrete number of major structural changes that will happen leading up to DF 1.0, and each of these long release cycles does, in fact, complete some certain major structural elements, thereby reducing the number of future extended release cycles.
