I don't think that it will have a huge impact, but I need to change a few things regarding to the bandwidth tab in the coming days. If there should be any issues, I will fix them directly after the fork and provide a new update as soon as possible.

It may happen that users with little SP are not able to perform all actions in the coming days. I think casting votes will still be possible for all users, but more costly operations like 'follows' and 'posting/commenting' could be affected and lead to some error messages. It's difficult to predict how far that will go, but I don't think that it will take much time until it will work stable.
