Apple releases Safari 3.0.1 for Windows through Apple Software Update and through its website (http://www.apple.com/safari/) today. Apple is addressing the security issues found shortly after the Public Beta was released. (http://www.macrumors.com/2007/06/12/safari-beta-security-slammed;-8-vulnerabilities-found/)
I guess that’s why Apple released the Public Beta, they want work the bugs out.
