This should have been posted in the help board sonce you're merely asking a question and not really bringing anything up for discussion.
As Jenga mentioned, all that can be done is minor changes to the game. Some may strengthen the security and help us be more protected.
FeralHeart itself cannot be updated for now as the game's creator KovuLKD has chosen not to let the staff have the source file which is necessary to make greater changes to the game.
We cannot blame him for keeping the files for himself. It is his creation, after all.
