Where Are The Patch Notes?

After a few days, the take them down because there are other news stories. You can check them from the game launcher

But they didn't update all pages with the new stuff, so you can go to an error:404 page and it'll have the old navigation bar which you can use to select Patch Notes news (among other things);
