Unfortunately sometimes users have no control over it in many software. "Regressions" is probably the wrong word[0], but new features by definition have new bugs in them (they're code that wasn't there before, so the bugs in that code weren't there before); the problem is that some security fixes for the pre-feature-X version aren't available without adding the new bugs introduced in feature-X code. 0: I was aiming for the opposite of update in the sense of adding bugs rather than removing them.
