Final rules for Olympics Spectators?

Does anyone know the final rules for cameras for Olympics Spectators. They were supposed to be released last week, but I can't find them.
I have heard rumors of all of the following - hoping if there is a rule, it's i)
i) Camera and lens < 12 inches long
ii) lens < 6 inches long
iii) no detachable lens
iv) No focal length > 300mm

Any insights?
