After Ryan Lochte went rogue at this summer's World Championships with a new breast-to-free turn in the 200 IM, FINA has issued a clarification to its rule on IM turns: "Being on the back when leaving the wall for the Freestyle portion of the Ind. Medley is covering more than one quarter of the distance in the style of Backstroke and is, therefore, a disqualification. Backstroke swimming is only defined as being on the back."
Read more about the new rule on Swimming World's website and look for the next edition of Streamlines.
