Apple have released a Security Patched version of Safari for Windows (v 3.0.1). The patch fixes security vulnerabilities in Safari I wrote about earlier this week.
There is still no fix for the bug I highlighted earlier this week (clicking on the x to close a window with multiple tabs doesn’t alert you and goes ahead and closes all tabs).
It is still beta software and should be used with extreme care for the moment.
The download links are on the Safari Download page.
