The last big change I can remember was when they added the new tactics. Box and one and isolation. Problem is none of them seem to be that popular and it was a long time ago now. They have made a few economic changes in recent seasons. 5th and 8th not paying salaries, salaries going down, free agents coming back, then less free agents coming back with the $10-$20,000 minimum salaries needed, the salary floor and probably a lot of others. There was also the new scouting system which is a lot better than the old one although I still think they need to improve the median standard of the draft (not the top). So that is a lot of changes really.
