I heard that they're planning a patch sometime this week that has over 600 changes which probably includes bug fixes, performance enhancements, feature additions and other improvements. It was just a rumour here in the forums though which I dunno the source but they did reference 600 changes so it seemed likely to have come from some official source. They seem to be doing well so far with putting out 2 patches in less than a week so I'm guessing we'll keep seeing that for a while.
This was said by Eurogamer. But the news suppose to be false according to pcgames. This was just a misunderstanding a CDP official claims because these improvements were already released with the day one patch.
They of course continue to support the game but no official release date was mentioned thus far.
