As long as the "old" version that Fantastico provides is 1.0 on Drupal 5.7+, I think we can handle that. Once we get to 1.0, we'll be busy converting to Drupal 6, which will allow us to slow down and actually write a changelog and remember what our code really did 3 or 6 months ago. It'd be really nice not to need a 1.1 release for some time after the initial 1.0. I think we'll find plenty to backport during the D6 conversion, but it's a goal at least.
