I'll double check but as far as I'm aware they are all up-to-date. They are also all legit!
Regarding your other point, I was able to consistently real-time bounce one track alternative, so I agree it's good to have that option, but I'm still perplexed why real-time is fine but not offline. Right now, though, I got a huge freeze when loading another alternative and can't even force quit the app via Terminal!
