Default salary cap is now $90M, max salary is now $30M
This applies to new leagues only. If you want to change it in existing leagues, enable God Mode (in the Tools menu).
Additionally, all of the financial parts of the game (like TV revenue, merchandising, etc) have been scaled up too, and they will automatically adjust as you change the salary cap. Previously they didn't change at all, so it was very difficult to run a profitable team in a league with a high salary cap, and too easy with a low salary cap.
Let me know if you think this has introduced any balance issues. It is supposed to just be a cosmetic change, with every dollar amount 50% higher.
