In the past have you downloaded and used Beta versions on your live board? Do you download and just play around to learn new features? Don't you download it at all?
I have never upgraded a live board to a "beta" release. It's not only a security risk, but I've seen some funky things happen to those who have upgraded.
I would never run beta on my live site! Besides the fact that I would never get my tracker integration code updated fast enough to run the beta on my live site....
I've done it before, yeah. But it's not something we'll need to worry about anymore, I guess, since they're not releasing beta releases anymore (according to the leaked screenshots).
