Does anyone know when the Safari/WebKit SDK will be posted @ ADC? I read it was supposed to be out Monday, but I haven't seen it (If it is out, where?).
You need an ADC membership. The free Online membership will work fine.
go to http://connect.apple.com - you can sign up for it there. Once you log in, go to the downloads section - it's listed there. (Not called Safari, though, just Web Kit SDK.)
