Apple unveiled Safari 4 beta today, calling it the world’s fastest and most innovative browser.
The Nitro engine in Safari 4 runs JavaScript 4.2 times faster than Safari 3 according to Apple.
New features that are supposed to make browsing more intuitive and enjoyable include Top Sites, for a visual preview of frequently visited pages; Full History Search, to search through titles, web addresses and the complete text of recently viewed pages; Cover Flow, to easily flip through web history or bookmarks; and Tabs on Top. The new Safari web browser looks very impressive. If it really improves productivity is still to be found out. The new features look stunning though.
Safari 4 is a public beta for both Mac OS X and Windows and is available immediately as a free download at www.apple.com/safari. Via this Apple announcement. Update: Read my first impressions of Safari 4.
