The appearance of levels has been changed, though nothing about the power of your character has been affected. The old level system showed extremely high levels and we wanted to bring the numbers down to realistic looking values. Your new level is just your old level divided by 100. The purple bar underneath indicates how close you are to getting another level. The yellow experience bar indicates how close you are to being able to train your stats just as it has always been. Nothing about the way leveling or bonuses that help leveling has changed other than the appearance of the number. All level requirements have of course been divided by 100 as well.
