You can get the difference between the two transformations by multiplying the new one by the inverse of the old. (If these matrices are pure rotations, with no translation/scale/shear, then this inverse is just the transpose) $$R_\text{diffference} = R_1 \times R_0^{-1}$$ Now you can extract the quaternion representing the rotation from this difference ...
