As we are working our way towards the full release of the game we have fewer huge new features to add in these updates. We have a number of super exiting features lined up for the release, but as we like to keep those under wraps for now.
Still we don't want to hold out on bugfixes. For a full list of fixes have a look at the Changelog forum topic: http://steamcommunity.com/app/207140/discussions/2/598199244892373717/
Meanwhile we opened a new season of King of Speed! We have a video of the edition of last weekend. You can also vote there for the new contender for next weekend.
