Now it forces this to be broadcastable. +Since this affects some legacy code, this change will require discussion +during alpha or early beta testing, and a decision to either keep the +stricter behavior, or add in a hack to allow the previous behavior to +work. + The functions np.diag, np.diagonal, and <ndarray>.diagonal now return a view into the original array instead of making a copy.
