The players got the new date in game and I'v added it to the description(Now a bit better to see). The reason for the late notification is that I made the decision yesterday. And the reason for the delay: I created content, which I did't added to game, because I wanted to do improvements and bugfixes first. Now I have many bugs fixed, but the new content is not implemented. I said which content will be in the next update and the update isn't finished, until all new content is in game and working correctly.
@giantboss I would suggest to calm down, because it's just a small delay.
