I've made quite a few changes to Upgrades, which you can view here on the
Upgrade page.
The biggest change is that of Power+. Power+, to be renamed to Inferno with due time, is now a monthly based upgrade. The idea of this change is to get back to the roots of Power+, making it limited with special perks.
The lifetime upgrades, now in the order of Onyx, Power and Supporter are to stay under the same names and look with different perks. All of this can be seen on the above linked Upgrade page.
The Investors group is to be deleted and Verified is to be redone with a better, more secure process. Yes, you will have to apply for Verified again once the new system is in place.
At the time of import, all current Power+ and above users will be given Onyx and Power.
Power+ users will be given one free month of the new Power+ from the time of launch, and those who had Supporter will get two free months. These do not stack.
