Yesterday Apple released a Beta of Safari for Windows, some user, including me, think it is more Alpha. Thor Larholm found a security lack after two hours. I found two bugs related to the rendering engine WebKit. Several other people experienced problems with Font rendering in the whole Application.

Excerpt from the License of Safari 3:

You should help Apple and the WebKit Team to fix as many Bugs as possible till the official release in October.

Download it, use it (but carefully), report Bugs to the WebKit Team
