There was a question over in the Beta topic (now closed) about how quickly the beta process went, and I thought I'd comment on that here.
Between the great work of the Alwil team, and the feedback from beta testers, betas here do tend to proceed to final release fairly quickly, typically a couple of weeks or less. That's for sub-versions like this new one, of course -- full versions, like the upcoming avast 5, will probably take a fair bit longer in beta before becoming final. And as has almost always been the case in the past, we'll probably see quite a few sub-versions of 5, particularly in its early days, to fine-tune it and clean up bugs that either didn't turn up in beta or stubbornly defied fixing.
