Apple have updated Safari to version 3.1 to include support for a lot of cutting-edge technology (including client-side database storage), along with adding a native developer dropdown (enabled within the preferences section). With Firefox 3, Opera 9.5 coming soon and, erm, IE8, it’s looking like the browser market is about to make web developer’s lives a lot more interesting soon.
By “interesting” I of course mean more difficult!
P.S. Visit this page in Safari 3.1 to see some funky CSS animation. Coo!
