Don't know really, I got my hands on Kerio Personal Firewall 4.0.2 which was announced on fileforum.com, and isn't in Beta status according to the about window. Kerio probably decided not to release it. I never did like it that much anyway, it wouldn't allow me to remote desktop to another PC that had kerio 4.0.2 installed and wouldn't even popup the windown asking to allow access. It crashed a few times too.
