Today forwards, the Heatmap now includes some of the stuff that wasn't counted before. It now also tracks some stuff that isn't strictly speaking "ready" for the game, like some writing stuff and so forth. Basically, it more accurately grabs when I work on the game on some level. On the other hand, it also now is less clear when I am actually contributing to the code of the game -- but I don't think most of you really care about that. In short: it's less of a pure Git tracker now.
