"Safari 4 is an incredible success on Mac and Windows with more than 11 million downloads in the first three days," said Philip Schiller, Apple's senior vice president of Worldwide Product Marketing. "Safari users love the incredible speed and innovative features like Top Sites, Full History Search and Cover Flow."
The new operating system will also make Safari more resistant to crashes by running plug-ins in a separate process, so even if a plug-in crashes, the browser continues to run and the user simply has to reload the affected page. Safari running on Snow Leopard also delivers HTTP streaming, making it easy to deliver high-quality audio and video in industry standard formats from any web server without the need for browser plug-ins.
Safari 4 is available for both Mac OS X and Windows as a free download at Apple's Safari website.
