There’s a new release of Safari 4 (4.0.2) featuring improved stability in the “Nitro” Javascript engine and “the latest compatibility and security fixes” according to Apple: Apple - Downloads - Application Updates - Safari.

Now if only they would bring back that progress bar in the address line. It was a very handy way to see page loading progress, and I still keep looking up there expecting to see the blue progress bar filling in…
