I know that this history is incomplete, but as far as I know, this is the best reconstruction of Element´s history before 1.15 we have (including my additions in reply #51 ). That´s a pity. If I had known in June 2009, how much I would soon like the game, I would have made screenshots of all Patch Notes and Development News.
I also know, that I asked zanz in 2010, if he had Patch Notes of the time before 1,15 and he said no. But maybe zanz can tell us more...
