This map got an update, specifically in the sewer section. Secret 7 in the video is no longer available but the other sewer related secrets are still the same, they just look different. How you get to them hasn't changed. A new poster was added that can be found in the new sewer section where you go up a giant spiral in space. The poster can be found in a floating wardrobe pretty much right at the start of the spiral ascent.
