What about all the test cases that were written for new features in past releases?
I believe those are more commonly referred to as unit tests. They may or may not be run as part of automated regression testing; I've seen it handled both ways. They're often at a far lower (and less interesting) level than "real" regression test cases, which, in my experience, are designed to call attention to ambiguous changes in behavior--"Is that expected/intended from the recent code changes, or did somebody break something while fixing/improving/adding something else?"
To put it another way, the practical distinction (often) is that unit tests are at the component level, while regression tests are at the system level. YMMV, of course.
