It seems like the extra restrictions on liquids was very short-lived. Either they've decided that the danger is over or the complaints were just too much to handle. They still check PET bottles with some kind of detector, but that just takes a second, and otherwise there's no problem. There is a new poster up explaining about scanning boots and thick-soled shoes through the x-ray machine, and I had to do that once, but you know how it is... taking off your shoes is an everyday thing here, so nobody minds (plus they give you slippers).
