Turn 10 are busy releasing updates to FM7. You can find all updates and their release notes in this FM7 release notes thread on the fm.net forum.

The Oct 3 update addressed a number of stability-related issues for PC players and fixed some bugs in the game. The Oct 10 update also fixes a couple of issues, but more importantly changes the benefits associated with Forza Edition cars. They now only have CR-based benefits, and they're all percentage-based. This was done to address exploits used to gain ridiculous amounts of CR and XP.

I'll try to keep the thread updated as new releases come out, but know that you can always check out the fm.net thread for release notes!
