I've managed to get to all the affected windows, and have a patch, however it's completely untested. The main window that will be affected is the Persona window. There were major changes, however I think the version that everyone has now will still work, you just won't be able to access the new information that's been added. Also without the new version of the Newcharacterscene2 you won't be able to create a Beastlord.
Lordebon went through the file changes and posted a list by importance of the change, you can see that
here.
