There are plenty of bugs in pretty much all software. No one realistically expects them all or even most of them to be fixed in something as large as an OS with any version really. The last release of a particular version is just that, the last release of that version, it carries no implications of it being perfect or bug-free or anything like that. Again, it's just simple reality that has been in play for many years across many companies and all kinds of software (and even hardware).
Nice try, Tim.
