And what else did Apple unveil today, hmm? How about the final version of Safari 4! Yup, it should be available to download today at some point.

Apple’s touting Safari 4′s Javascript performance, something that shouldn’t surprise those of you running WebKit. Apple says it’s eight times faster than IE8′s Javascript engine, and also passes the Acid3 test at 100/100. IE8′s score? 21/100.

The biggest news, though, is that, like Google Chrome, Safari 4 now hands each plugin off to its own process. So if you’re watching a YouTube video and the Flash plugin crashes, only that tab will crash and not the whole browser. God that makes me happy.

That is all.
