let's use what we learn from Skywind to improve the process for Skyblivion.... Considering the core team is working on Skywind now, I figure it would be even more difficult not to forget anything. So I propose a tracker.
I'll try to keep track of what's released and where but you can update yourself also ;)
One sheet per release being prepared (meaning the current release being worked on is 0.2). When the release happens, the sheet gets locked and a new one is created (with potential left over).
Hope this helps.
