But do they care about bugs in previous versions? Or do they only address bugs in the current/beta version? I suspect the latter, which means there's a growing set of non-critical bugs which get re-reported in every version but never fixed (priority always lower than shipping new features). Otherwise, I don't know how to explain the seemingly increasing instability of the software: memory leaks, crashes, etc. I even bought a new MacBook Pro this year, and maxed out the RAM at 16gb, but Safari still crashes and has the same frustrating issues like the occasional won't-refresh-local-url-without-quitting-and-restarting. Such bugs don't get added with new features, they've been there for a while in previous versions.
