We posted a changelog as a wiki so its easier to navigate and update. You can now access it via the command menu as well as you can visit directly here:

While this is far from complete it should cover most of the changes in the game. As we add more I'll try and keep the wiki updated, just posting in blogs and in the forum is hard to track down all the changes so I thought this would make life a bit easier
