Just to confirm -- the changes to the "slaughter" rules won't invalidate any existing match transcripts, right? (i.e. they don't change the actual game tree)

If we have changes that modify the actual game tree, we need to increment the version number for the game, since otherwise match transcripts that reference this version will no longer make sense. If the changes are just cosmetic -- just adding base/input, just cleaning up rules, etc, but not changing the game tree itself -- it's safe to deploy the changes without increasing the version number. That's what I've been doing so far for the base/input roll out.
