Detailed changelog (since v3.1.0)

Note: This was already published previously. If you just got a second notification for this, it's because something went wrong when placing the original tag on the right commit, and the corresponding release was deleted by GitHub when the tag was adjusted. No action is required and if you previously pulled from the old tag, you still have the latest released code. Sorry for the inconvenience!
