I just finished adding all relevant Steam news on the News_and_Dev_Blogs, task which was very exhausting. So I will add what's on the official website later. I had to remove all images. First, because they can't be pasted and need to be uploaded before being inserted (which would take hours to do for that amount of data). Second, because the page would be way too big and too long to load.
I hope this will be useful in the future for research purpose. It will help tremendously in quickly finding what's been done with the game and when.
