We try to notify this list when API changes are made in Drupal 7, so contrib and custom developers have a chance to fix their code before they have the pain of figuring out why it's broken.

(issue) The function file_directory_path() was removed. If your code uses it, you now have a fatal error. The new public:// streamwrapper notation is probably what you want instead.
