So you remember when each release was made? And also when the corresponding release branch was cut? If you remember all that, then I understand why you don't need ChangeLog's. And mind you, in my scenario many times the date of the change is not given. Rather, someone complains about something in version XX.YY, and I suspect some feature/change, but don't have a clear idea whether that feature/change was introduced before or after that version.
