Is It possible to quickly replace a version if a major bug slips through?
That's completely impossible with the Mac App Store. I can't skip the review process. But that review process should normally prevent a major bug to slip through.

I have always wondered if it would be practical to have two updates available.
Of course, it's impossible with the Mac App Store.
For the other versions, the current system is good enough => if there's a big problem, I release a new version as fast as I can, and most users don't even notice.
