Yes, 2.6.8 changes the way prices are managed so that only one price is stored per day and in the case of currency exchange rates it’s stored in the direction that the number is larger than 1. The reason for the latter is to retain as much precision as possible, particularly in cases of fixed-decimal rounding. For currencies which trade in the range of 1 - 100 to one this may seem to be not important, but several minor currencies trade in the ~10000 to 1 range and rounding those prices can lose most of the significant digits if done in the wrong direction.
