It's meant a lot of different things in the past. The initial version (the "strong" hypothesis) has been roundly rejected. Claims associated with it are what people usually think of ("the Ancient Greeks couldn't see the color blue!") when they think of Sapir-Whorf. Weaker versions with much more narrow claims are debated and controversial, but even for those, it's the most flashy (and least supported) claims that get the most popular press.
