Over 204 bugs have resolved since RC5. Although bug fixing was a large part of the work, we did extensive changes to the software to add new features and improve how Sophie works. We completely rewrote the entire text edit subsystem to resolve issues found in RC5, along with adding new feature to the template system to enhance the ability of Sophie to make books. During this process we replaced the entire undo/redo subsystem with a new code base which greatly simplified the interface for developers and enabled many more commands/actions to be undoable.
