So, Version 3 has been live for a couple of hours. The plan from now is to work on a few of the early-reported bugs, and get another patch out later this evening; at that point, I'll be doing a full patch notes write-up (It's so much fun!)
At this point, there's one critical bug - if your Steam User name has a / or a \ or a * or a : in it, you won't be able to play. The version due to land later this evening has a fix that converts your username to a disk-safe name.
No-one reported this during the testing phase, so I would like to apologise.
Known issues and the raw patch notes are here :
